A&Q about 350Z
Q:
I was just reading the December issue (Volume 18, No. 12) and theres this "Dear Dave" section where people ask for car advice. This one guy writes in asking for engine swap advice for his 260Z, saying he was thinking about using a tripple weber L28, SR20DET, VQ35DE, or JTR V8.
"Dave" then gave some good advice about stiffening the chassis and went on to explain that his choice would be an SR20 because its light, powerful and has been done before, but that it didn't "sound right" for a Z. "Same with the V8", he said. He also dismissed the VQ35DE because he didn't think it would look or fit well in the engine bay of a 260Z.
It was at this point that he completely dimissed the carbed L28 because it didn't have any real power potential, even though we know that they can make 300 HP in full race form, and still well over 200 HP in street form. He didn't even mention the L28ET option, despite the relative ease and potential of this swap vs. many others. He then said that the RB25DET is the way to go, and that its "about the easiest non L-series swap you can do". What he doesn't mention is how expensive that option would be compared to any of the others. And it certainly isn't the "easiest" non-L series swap, a JTR V8 conversion would be cheaper, make great power, and is very well documented, yet he totally dismissed that as an option. I mean, SRs and RBs are great, but for the cost of either the SR or RB conversion, you could have a well built L28, L28ET, or V8...yet this guy doesn't even really consider them.
Is it just me, or is this "Dave" guy working for "Sport Compact Car" not giving very good advice? Or is it just that everybody gets a hard on anytime the SR or RB is mentioned, so thats what they put in their magazine because thats what sells?

Perhaps you should write in and tell this guy whats up. I think like you said he just said to go with the SR20 becuase it's popular. This guy needs a leason in Z's. Write in and tell him the error of his ways. You never know, they may put your letter in the next issue and the guy with the 260z will get better info as well as other readers realizing that the old L series is still competetive.

300 is more than that stock RB25 will make. i read that same article and put the mag back down. this was a kid writing in for good advice and for the advice he was given he'll need a decent loan! he also mentioned that the VQ35 is one of the "ugliest" engines ever built and seemed to be the primary reason for not going with that swap. seemed like an idiot talking out of his "whats the most popular car to rice up these days?" a$$.

GOOD!
It's about time to finally get rid of carbs. Compare the cost of tripple Webber carbs settup some time to that of a stand alone EFI system. Why pay a hell of a lot more for tripples just to have less mixture control than even basic EFI?
It's also good to dismiss the L28. As much as I like it, it just takes a lot of money to make 2hp/ci in that engine. It's much easier, cheaper, and reliable to drop in a crate V8 and loaf along with 300-400hp before doing any mods at all.
Sorry to burst anyones bubble, but small displacement single cam N/A engines sucking through carbs ARE limited in real potential power.

The cost is only great to make a l28 fast if you pay someone to do it. My budget is under $400, and I am almost entirely done building mine. I did all the work myself. 280zx Turbo oil pump, all new bearings, lash pads, rocker arms, custom ground camshaft, new block, pistons, rings, hand ported e88 head, hand made 4 barrel intake manifold, milled head, decked block, and all the gaskets, Taylor 8mm wires, and all the fluids. Still havent broken the budget with all those parts and work. Cost isn't as great as you may think. The headwork I have done alone, had someone else done it, would be right around 1,100 at a professional shop. Building a 128 is cheap. Having one biult is expensive. I will get it dynoed for ya'll later, along with some 1/4 mile times, 0-60 & all that.
A:
VG30ET is quite a capable engine folks...
Probablly a pain in the butt to put into a 260z though.
And yah, 300hp isn't much...
He should just swap in a v8. Easy as pie.

Give the buy a break. He can't know everything about every car. He gave a pretty good answer IMO, all considering. Not everyone is a z expert, not sure if you noticed, but 260's are 3 decades old. That guy isn't going to know everything about every import in the last 30 years.
Maybe he didn't suggest the L28 because most kids don't want to put a 30 year old engine in their car to replace the 30 year old one they already have. Most people swap for at least a motor of relative reliability compared to the one they already have, if not upgrade. Let the L series be underrated, just makes it that much more special.

no for the guys who do make, hats of to you... but these are usually the guys almost done with a shell-up resto's, and had a badass plan from the start.
id put any of those engines in a Z, regardless of what's better than what. i love the living crap out of my Z, but the time's coming up where i need to rebuild my engine, and im questioning the L myself. (probably do a an f54flattop and shave my n47...clean the **** out of it, and put it back together).
the guy giving advice just seemed like the 240sx guys in my area that want to put SR's into everything... because they think it's the "end-all" motor.
that crap bugs me.

the guy writing in sounds like a young guy and since he is asking a guy that doesn't seem to know a whole lot about early z's which motor he should put in instead of researching, he probably doesn't need his grubbers in an RB swap, an L28ET is going to be the easiest and most cost effective way to extra ponies. and as far as dismissing the carbed L28, the guy obviously hasn't seen a properly tuned, race ready one like norm's or he wouldn't make comments like that and "even if its bored and stroked out to the full 3.0 liters". how about a 3.2?? oh and a race prepped RB25?? haven't seen one in a z, maybe i missed it. doesn't sound like it would be on too many people's budget. I'd rather have a 600 HP L28 like Jeff P's if given the choice, even though the RBs are bitchin engines.

If you could then more people would do it no? I'd like to see this 600HP L28 and know exactly how much he did spend, otherwise there's no logic in saying that it's cheaper than an RB series engine and therefore no real reason for it other than motor preference.
This has infact been discussed before,
It seems many people share the opinion that it costs too much to modify the L28, and that an RB would be the better/cheaper option in the long run.

so only one guy in the second thread you posted chimed in about an RB but everyone else suggested modifying the L28ET...what was the point? the first thread posted was about a kit on ebay, and whether or not it would make the power. we aren't talking about an ebay turbo kit. yes the RB has the advantage with a second camshaft and double the valves but is this the best swap for the kid writing in to the magazine? probably not if he needs a magazine editor to tell him what engine to put in his car.

That engine above is nowhere near that much money. You can find completely rebuilt l28's all day for $400. It's all in the shiny parts, and the triple webers.
A:
steveosupremeo,
The point being that it's a commonly shared opinion amongst YOUR fellow 240Z guys that the L28 costs too much too modify vs just transplanting another engine in. Dont shoot the messenger, I'm only going by what others have said in the past. I'd prefer the L series engine myself over an RB anyway, because here RB's are boring and every second car almost has one.

if they are boring send one this way and i'll drop it in my wifes 240sx so she won't have to stress out that KA anymore, lol. i do agree that a V8 could be dropped in and make more HP for less than a built L28 but the parts for RBs over here are very expensive unlike over there i'm sure. in other words the swap itself might cost less but not the mods thereafter. just two weekends ago there was a Z32 with an RB26 and he did ALL the work himself, putting about 350HP to the wheels (claimed) and had about $6000 in the swap. and he was still using the stock fuel management. i do think i could get that much out of a built L28ET for less but i guess i wouldn't know without actually trying. oh well.

The RB26DETT is a very expensive engine no doubt, and freight to the U.S would definately be the ultimate killer. RBs are overrated in my opinion, alot of my friends are Skyline/RB nuts but as I said they are a VERY common engine here. Every second ricer has a Skyline and the Holden GM Commodore uses an RB30 for example and so does my Mum's Skyline Ti pos, they really are a dime a dozen here. With that said though, not alot of people want to bother with old carbs though as it just cant compete with EFI setups running standalone systems as far as tuning capabilities go.

I have not read this article yet, but the Dave in question is most likely Dave Coleman. He is actually a very articulate and well educated Nissan guy. He even races a 510 in U.S. rally racing. He is in all reality the MOST Datsun friendly guy writing for a major magazine. He knows all about the Z car and attends many of the classic Japanese car shows on the West Coast. I personally think that most of you are reacting emotionally as though this is an attack on you personally. Look at the engines in question. In all reality the SR is most likely the cheapest of the bunch. Especially for someone with a limited amounts of connections in the Datsun community. Have any of you priced a set of trips lately? A decent used set will run most people $750 or more. L28 engines are not exactly all that common any more in a lot of parts of this country also. And even if you get one it could most likely use a rebuild after 23-30 years of use. No one is saying they are not great engines. But an S13 SR20det can be had complete for $1500 almost anywhere these days. Yes there is a cost to the conversion, but we are still talking about a running ready to use drivetrain with more aftermarket support than most of the others. And please, let's not have anyone say how you can get a 300hp V8 for $200. Any V8 worth anything will cost as much as an SR and will also require conversion parts. Looking at it objectively, it's probably the best advice this kid will get.
Brian
A:
I completely agree with Brian's post above, I have subscribed to SCC for the last 6 years or so, and Coleman is a Datsun head, and seems to know more about them than most. I just got my mag a couple of days ago, and I always do the "fast scan" through the thing to see how much Datsun/Nissan stuff is in there, IMO it is probably the ONLY import oriented magazine worth buying, ever notice how they dyno nearly ever car they test or feature? good stuff. One of the editors did a story about his dream car collection a while back, and one of his dream cars was a 240z, but with some Toyota engine, ZG flairs, and some other stuff, bottom line, I thought he gave pretty good advice, although why someone would ask a magazine what they should do with their car is beyond me...
as far as cost, speed costs money, making a Z car fast, as well as safe and reliable isn't what I'd term cheap, I've owned several S30's one '78 with a hot 355 SBC, and a '72 with an L28 and 40 DCOE's, and my current turbo car among others, they were and are all fun cars, but everyone has their own idea of what the ideal Z is... I also liked Brian's comment about the V8, anybody that thinks making 300HP to the ground with a decent quality V8 swap is all that cheap, has a different idea of what cheap is than I do...

As to those sucky carbs, EFI is no doubt a more reasonable way to go but the 44mm Mukinus on my 3.2L make such a great sound that common sense is overruled by auditory sensation. I've driven cars with six of those sucky carbs and the sound is almost overload to the brain......not to mention the throttle response.
A:
I personally would be shocked if EFI made any more power than a well tuned side draft carb set up on an L motor in an N/A application, cold starting, general driveability, and emissions I could believe, but I would doubt EFI could atomize fuel any better than a carb when optimally tuned, the biggest problem is getting carbs tuned that well... and forced induction is worlds easier with a well designed EFI system, though some of the carbed and supercharged V-8's I've played with, roots and centrifugal, run very well. I'm considering lowering the compression in a 427 BBC I own to run a carbed centrifugal in my '69 Camaro, after riding in a buddies Vortech blown, carbed SBC '70 Nova...

I wouldn't be shocked at all... Combined with a standalone system it can do alot more than just adjusting the fuel mixture, the major thing being ignition curves aswell.
The 3D surface graph enables the tuner to get an instant visual representation of the engines fuel and ignition curves. Thus visual feedback quickly shows any erroneous data so tuning becomes faster and safer. The analog style gauges, display real time engine data giving more information at a glance. EMS has an optional Data Logging system that the user can call up at any time.

I dont care how well a carb is tuned it cant even be compared to the performance level of EFI setups combined with stand alone engine management systems or even just a socketed stock ecu, turbo or not.
Overall it's apples and oranges really, some guys prefer carbs other's perfer EFI but EFI is far superior when it comes to serious tuning.

I have loads of personal expierience with stand alone EFI set ups, Accell DFI, Electromotive and run a Haltech E6K on my own car. quicker and easier to tune, maybe, and certainly a better solution for forced induction, but on a normally aspirated engine, I doubt that EFI would make much of a difference in peak power output, as I said in the last post, drivability, emissions, and the not insignificant feature of having your engine start when it very cold outside everytime, are worthy reasons to go with fuel injection on an N/A engine, but I personally don't believe that total power production would be enough of a reason on it's own to dump carbs for EFI, at least on an N/A engine
"The 3D surface graph enables the tuner to get an instant visual representation of the engines fuel and ignition curves.

the 3D graph above does exactly what the text says, gives the tuner instant visual feedback, and is very helpful ensuring you didnt accidentally miss a cell or something, and you can also adjust a bunch of cells at once, instead of messing with jets and emulsion tubes and stuff. and springs and advance weights in the dizzy, and is much easier to get to the end result of an optimum tune, but I stand by my opinion, that the end result (power output) will be so nearly identical EFI vs. Carbs, properly set up and tuned on an N/A enigne as to not give a clear power advantage to either system

I guess talking specifically about an NA engine you could be right, but who cares about NA... hehe :) I'm joking of course, but I'm a turbo fan boy so my opinion is totally biased. Once you go turbo you cant go back, my first Z was an NA and after I got my first turbo I'd hardly drive the NA as it was so painfully slow in comparison. But that's another story for another day lol

some of the stuff posted here on land speed cars by tonyd says they made 40 more hp from the twm itbs than with the webers they had and that they went with the efi because the cost for new 55 webers was as much as it was for the efi and with the efi they got spark control so they went that way. 40hp sounds like a fair bit. there is a lot of stuff in the archives here, i have been reading and reading and its amazing what has been covered and listed but it takes a while with the winter weather here i got nothing but time!

A:
I think this has gotten a little off track...the point was that Dave totally skipped over some of the cheapest and easiest swaps to get more power...and instead went to the thick wallet, deep pocket, Skyline and Silvia engines. Seriously...he didn't even MENTION the L28ET...wouldn't you expect a supposed "Datsun Guy" to at least bring that up? Just kinda "get that idea out there"? The guy who wrote in asking for advice would probably have been very happy to hear about some of the many other options...but he didn't...because Dave totally dismissed them.
As far as him not knowing "everything" about Datsuns...yes...if he is writing for a major import car magazine...I do expect him to be knowledgable about these things. And if he isn't...at least do some research.
I don't think anybody here seriously believes that the L6 is the end all be all of internal combustion engines...because it isn't. But lets face it, well built NA L6 motors...even carbed...are well documented to motivate early Z cars to 14, 13, and sometimes even 12 second quarter miles. How many modern and fuel injected 14, 13, and 12 seconds cars are glorified on a regular basis within the pages of Sport Compact Car?
Short answer: A lot.
And yet...the L6 is completely dismissed. Hell...the May issue of Sport Compact Car featured one of our own "ZCars of the Month"...and it had an NA L6 motor. So why the sudden change of heart?

And the point was made that it's not cheap to get BIG power out of the L series motor so he did get sound advice and for the record 12 seconds isn't that fast at all.

It may not be cheap to get big power out of an L6, but its also not cheap to swap an RB into an S30.
And maybe 12 seconds isn't fast enough for you...but is this guy tryng to win an NHRA championship? 300zxt, you're taking this out of context. He didn't even say how fast he wanted to go...trust me...I have the article right in front of me.
Fast is relative...if he's used to his stock L26, don't you think he would be happy with an L28 that had some headwork, a little bigger cam, decent exhaust...etc? Or even a stock L28ET with the boost cranked up 2 more psi?
I know I would be...not everybody needs 4 digits to their horsepower number to be happy. And how can they disrespect the L6 when they regularly feature cars that are on the same playing field as early Z's with well built L6's...aka...14, 13, and 12 second cars?

Well one would think that "engine swap" advice means exactly that, to swap one kind of engine for another. My guess is that's how the guy interpretted it and answered accordingly.

Hmmm...I think I might have paraphrased it using the term "engine swap". It was implied that he wanted to do an engine swap since he mentioned a few different engines, but he never specifically said thats what he was after. So let me copy it down exactly as it was written in the magazine:
"I have a 260Z project car that I started in college and have almost made roadworthy. I've redone pretty much everything but the engine. Before I go putting time and money into my (t)rusty L26, I've thought up some alternatives that seem like they would pay off bigger."
He also mentioned he wants to race at local SCCA events, and most of these engine swaps would break the rules anyways (which Dave pointed out). Then he started listing off the different options asking for advice. Like I said, he mentioned several non L-series engines, which shows he's open to the idea of swapping, but he never said he was against doing some engine mods...like an L28 build up, etc.
Kind of a judgement call as to what he is or isn't open to. Nonetheless, I still think there are a lot of decent options that weren't even mentioned...and I expect more from a major magazine like Sport Compact Car.

I can see both sides of the story, purists wanting to keep the L series in there and feeling burnt that the option wasn't even seriously considered, and on the other side of it spending money on a newer engine with more aftermarket support and tunability. Idealy you need more information from the guy, but he got free advice and it's up to him to make the final decision. We can b!tch and moan all we want about what he should've been told, fact of the matter is it really depends want you want out of the car. If restoring to an original and wanting to compete in restricted race classes then sticking to the L series would be sweet. But if he doesn't ultimately care about that in the end, and wants a newer engine with more aftermarket support as a blank canvas to work from then that'd be the better choice.

I'd agree with that 300zxt, although the SR and RB engines really don't have a ton of aftermarket stuff in the U.S., there is some, but remember neither engine was ever brought here by Nissan, at least not the turbo models, the SR20DE was available here in at least the SE-R sentra...

12seconds is pretty fast... Consider that a Z06 and a Viper SRT10 do the 1/4 mile in 12ish seconds...
Now you just gotta tell me that the Z06 and the SRT10 are slow cars... Then I can know for sure you are just throwing a giant pile of bullshit around. :P

someone saying 12 seconds isnt that fast are usually people with 18 second cars and live on the internet making such statements! LOL!
A:
While I agree 12 seconds isn't FAST nowadays ,I still think it's damn fast when you are doing it Normally Aspirated with all slightly modified stock 30 year old Datsun parts except camshaft of course.
BTW I looked at your website 300zxt, but I can't find any times for your own daily driven Z.
BTW, what does your personal Turbo car run in the 1/4 mile??

With the mods he has, i'd wager 13seconds max :P
Either way, 12 seconds is still fast as hell!!! Like I said, a Z06 and an SRT10 Viper do the 1/4 mile in 12 seconds... Heck an enzo ferrari only does the 1/4 mile in 11 seconds...

The SR is actually supported widely by many shops here in the U.S., and the RB to a somewhat lesser extent. I can rattle off a whole laundry list of shops that sell parts, and actually have knowledge of these engines here in southern Ca. I can drive to a shop about two miles down the road from my office here in San Diego and buy a stroker kit for an SR if I had the money or need. Now if you live out in BFE, Nebraska I can see how you would have trouble finding parts for these cars.
Money not being an issue, it is probably just as easy to make more power with an L series as it is with an SR or RB. The SR and RB just have more support from the aftermarket.

there is not one local shop in my area that sells SR or RB stuff. but i can go to a salvage yard and get the parts i need to build a bad ass L engine with the exception of the cam and plenty of companies make cams for the car. i've seen the prices for parts for the SR and RB motors, not cheap at all compared to parts for the L series cars in my opinion.

i'm interested too, i don't know what mine run but i'd guess somewhere in the 15 second range right now. maybe high 14s on the 82 with the mods. but of course i'd feel like i'd have a pretty fast street car if i ran 12s. but i guess i'd be a slow poke holding up the left hand lane like norm, LOL!

>Hey 300zxt what does your car run in the 1/4 mile??
I haven't ran it yet actually, there's still alot of mods to do yet for the power level I want to achieve. I'm aiming for 10s over time, although eventually my 86T will be fully drag prepped and not street legal by the time I'm finished! It's been on a backburner for the last 6 months because I'm moving states soon so funds are limited right now and I've only had that car a little over a year but a fair bit has been done to it so far. Oh and I suppose having 2 new Z's doesn't help matters either, I couldn't pass them up! lol I have an addiction...
All in good time though, I'll be sure to keep everyone posted! :)
