Q:
I got a new set of toys today. I have been waiting for these parts for a few days. Needless to say they have created quite a stir with a few people.
I am planning a roller rocker cylinder head and things are looking good for the build.

So you were the one that bought those off of ebay, I was wondering who would be the one to get them.
Are you going to design a new camshaft to go with these rockers then?
I cant wait to see them installed and the effect they will have with your motor.
The only replacement for displacement is boost
A:
That's great. Your car can be down for another year and you can now claim to have 650hp. Keep up the good work. HEHE!

Are those the ones made by Malvern? I seriously considered going with his roller setup, those look very similiar if not the same.

<That's great. Your car can be down for another year and you can now claim to have 650hp. Keep up the good work. HEHE!>
No James, this is going to be a special application. My car will be ready by the 15th, in fact I have been invited to a private day at Fontana Raceway. I just may take the car.
True my car has been down for a few lengthly times, but it has nothing to do with money, or what I was doing. Fact is I just cant do all of the machine work I need to have done, and some of the machine work I wont do just because I wanted it completed by some of the shops I have dealt with in the past. I have to say, Nathan did a very nice job on my cylinder head, and truthfully, he did about the best job I have ever seen on a nissan head and I have looked at a few. Just for your information James, I really don't know what your problems is, but I can tell you one thing. I am really not in a hurry on my car at this point. I know exactly how it is going to perform. In fact, there are people I know of that don't even bother posting on the internet that have very close to what I have, and their dyno numbers are higher then ANYTHING I have EVER seen posted on any forum, yes even your numbers james, not that they are all that impressive anyway. So when you start producing 700 foot pounds of torque with your setups, then talk to me, until then,shut the F$#K up.
I am not interested in your Hp numbers in the least. No, what I am interested in is when does the TORQUE come on, how far it lasts, and how much you produce. So that being said, show me something that is impressive, because up to this point you have not. The graphs I have seen from you are just about what I was making, or a few foot pounds over when I had a leak between #2 and #3 cylinders, and with the recommendation from you on how to set my valve last, WHICH I should have NEVER listened to, hurt my numbers significantly.
Just a little history, David Webber at Malvern was working on these parts in a Nissan application in 1999. As you know David has passed away, so my only other contact was the guy that did all of the R&D on the project. I was able to get his phone number yesterday, and gave him a call. Seems his shop is no longer in business, and he was not home. I would like to get his information on the project and what the final outcome was. I am going to wait on letting the manufacturer out on this one to save the guy from getting inundated with lookieloos. This is not going to be a cheap build at this point. After all of the R&D is completed and all the NRE charges are paid we will see just what the setup can be bought for.
Just to give a little more info though. I am thinkinjg on the new beehive valve springs, stainless steel valves, and believe it or not a P90 head for the project. I like the idea of build it and run it without messing with valve adjustments.
So there is more work to be done. I have contacted Nathan at BC, Ron at Isky, I still need to get into contact with Bob Beatty I use to work with regarding some of the finer details about cam lobe hardening, you may have heard of him, and if not look at the members of the 235 mile an hour club that ran on the salt flats, he is a member. I did also speak to Clark Steppler and discussed some of the engineering challenges as well. So there is still some work to do, and a good machinest friend about modifying the cam towers, also, I just may go with a set of needle bearings for the cam, so I have to get some more info on the bearings for that little project.
Needless to say, this is going to be expensive for the first head, but with a little work, it just may be a viable option for the L28 engines at a cost that people would be willing to spend the money on.

Jeff, you have to know I am just trying to get your goat. My setup made 509ft-lbs@wheels. The highest torque value I see on your website was 410ft-lbs@wheels. Only 100 more to go!
I have also seen others make more power than me so it bothers me not. I exceeded my expectations considering the small turbochargers, lack of cam and adequate head work. I also backed it up with consistent 134mph runs in the 1/4.
I have to give you hell as it is in my nature to do so. Until we see proof I have to give you hell regarding your claims. Heck, I can't even call your car a dyno queen because you haven't backed up your claims with a dyno graph saying it makes 600hp.
I do hope you reach your goals, but there has to come a point where you substantiate your continual claims. BTW, what is the estimated 1/4 times. Did you not use to post it was going to run low 10's or high 9's?

<410ft-lbs@wheels. Only 100 more to go!> WRONG it was 475 foot pounds.
Yes James you do get my goat to be frank. I really dont know why you have to do that kind of thing.
Dyno queen, well maybe, I guess its all in the way you look at it. I dont abuse my car at the track, why, first off I haven't been able to get a few critical parts to last any length of time in the car like the clutch, until I hooked up with Robin at Superior friction, problem solved. I ran the car five runs getting on the freeway @ 27 psi of boost and took out the diff, I took the car to the MSA show that year and it was howling for mercy. Then I rebuilt the diff with all new parts, the car was down again, and I still haven't been able to verify if the R200 is just to small or not.
Then I wanted to upgrade the fuel management, and I needed to up grade the turbo. I first ran a TO4E with a 62-1 compressor with the stock exhaust turbine housing and exhaust manifold. I felt I would reach crossover with that setup to get to 30psi of boost. So I spent mucho money on the South Flordia Performance header that turned out to be a total mightmare, so now I am on the second rework with that part, and again a new turbo the garret part. Then the upgrade of the fuel management in the car, and you like to give me crap about running the Nissan box, and maybe it is not the Ideal fuel management, but that will soon be a thing of the past for tuning, so I dont know if you have taken a close look at my pics, but I had to get a 4" inlet pipe to the turbo, and the intercooler pipes through the radiator support without hacking the hell out of the car in the process, and which I might add you gave me crap about the sizing of the intercooler and the pipes a while back. then the tranny upgrade I did, only to find out by the time I completed the install Gforce decided to do a new gearset of the old part. Calling the UK to verify the diff carrier because Quaife USA doesn't know what the hell they are selling. And that is not the half of it.
So I get all this s#it completed, and a new oring fuel rail I designed and machined all of the parts for and then I got a new head because I was not happy with the cam I was running and the new grind would not even come close to working in the head without coil bind, so a new head, done the way I should have done it in the first place. So I finally get all of this crap finished up and go to get it on the dyno and tuned and it screws up, the ignition MSD failed, and it spun the oil pump drive gear in the shaft and screwed the timing, which all four of us, and everyone I have talked to said they NEVER had seen before, happen to my car.
So in addition to waiting for some work to be completed for months on end, of which I have spent thousands and thousnads of dollars for, reworking parts that again I have spent thousands of dollars for because the builders cant get their s#it together and put every other project in front of mine, AFTER I gave them thousands and thousands of my hard earned dollars to them to get excuse after excuse as to why my parts were not done.
Then after I have gone through all this s#it, I get to listen to you give me s#it about how my car is this or that, YEA it pisses me off James. I have done everything I can to get the work done, thrown boats loads of money at it and it still took forever. Hell I have two registration tags that I never put on the car because it was down, it never left the garage. Sio YEA I get a little ticked when you give me crap about my car. I put some outstanding engineering and design work into my car, that I am quite sure nobody has done to any zcar, the frickin car looks stock with nice tires and wheels on it, but I can tell you one thing, NO production car has touched it when it was or is running hands down.
I did not build a track B!tch that can only be driven at the track. I built a car that I can have some fun with, hell it doesn't even have a roll bar yet.
The car will be in the 10's no problem, and it will last doing those numbers. I dont think you have ever taken the time to realize the difference between 500hp and a 600hp car and all that is involved to make a well rounded car. Oh don't forget about the brakes, I had the first set of 12" brakes on a zx car that I know of, and there again, I had to redesign the system because of the engineering error made in the first place, and AFTER I had that upgrade completed 2 years, THEN AZ zcar decided to do a 12" upgrade for the ZX. It seem like every upgrade I have done to the car has been copied, by business that MAKE money off the whole deal AFTER I blazed the trail for them. EVEN the FRICKIN exhaust was copied, after the companies I approached in the first place asid it would not sell only to now sell a sub standard part in my oinion years AFTER I did the work.
So dont give me any s#it James, I have done a exhaust upgrade, waterpump upgrade, tranny upgrade, brake upgrade, suspension upgrade, tire/wheel upgrade, diff upgrade, Damper upgrade, ALL of which someone else has capitolized on for their own car, or financial gain through a business. So yes that does have a tendancy to piss people off to see so many make profit off my broken back, money spent for R&D, just so I can have the kind of car that I like. Not to mention all of the engine upgrades I have completed, custom oil pan, that was suspose to fit, but was built for a 240z, that I modified to fit the zx cars, that started out @ 750.00 for a pan I could have built for 200.00 ONLY to hack it up to get the damn thing to fit.
Now you give me crap about building a roller cam setup for the L28, which ON ONE has EVER done before, mr doom and gloom, so I will say it again shut the F$ck up James, you really piss me off at times.
Now, the car will not get into the 9's! IF I WAS going to build a drag car, I would do the car totally differently, and one of the first changes would be the tranny and go automatic, I just lose to much time shifting, it's hard on the drive train, and to much hassle to keep. Then a roll cage foe sure, then go back to the engine mods, wheels and tires, half shafts, and diff. so there you have it.

Jeff,
Now that is cool. Don't let anyone get to you. My take on cars is enjoy doing what your doing. If it takes a while so what. Since you're doing something not done before take pride in it.

I started to read your reply, but became very dizzy in the process. Sorry for the mistake, 35ft-lbs to go. Here is a list of things you still need to purchase:
1) larger turbo(will even give it to you at cost)
2) custom intake(stocker won't cut it)
3) fuel management(JWT=Bad Choice in my opinion)

Damn Jeff, that was a one big excuse! Nine (count em) NINE paragraphs!
You say you don't even want to drag race it, but then you claim it "will be in the 10s no problem" You mean except for the problem of anybody actually seeing it run in the 10s, right?
Admit it, what you really mean is "I will claim it is in the 10s no problem. Even though it will never run in the 10s people will believe me because I talk up the size of my car's E-Penis on zcar.com every day".
Don't hate the messenger, James is just telling you that you talk too much and your car never performs. The truth hurts, get over it and quit whining.
A:
Not to take any sides, but, jeff...you should definitely go bigger with the turbo, bigger intake...I'd do a megasquirt before JWT, personally...
Your car is very impressive. The workmanship is excellent. I don't think the cost of some components was worth the performance gained even in some instances where parts weren't available, but cost obviously hasn't been a factor in this build.
I'd like to stay out of the pissing contest, but c'mon, this is typical motorhead behavior, we should all be used to it by now. Even the guys you respect the most get their share of naysayers...and rightfully so. We don't build powerful cars just to be humble about them. We boast about our own. We doubt our competition.
I would have also taken a bit of offense at the statement initially, but I don't think it's worth getting all riled up about...
I KNOW!!!! JEFF PRIDDY VS. JAMES THAGARD WINNER TAKES ALL DRAG RACE EXTRAVAGANZAA!!! THIS YEAR @ MOTORSPORT!!!
LOL.....
BTW- to clarify!!! I love both of your guys' vehicles, you have both been instrumental to the Z community for many years and we all thank you both for posting your trials and tribulations for our benefit here at zcar.com. Now can't we all just get along?!
