A&Q about 350Z
Q:
Today, I was at the dealership while my buddy was looking for a new car. I saw a nice 04 350 with a Nismo exhaust and it also had Nismo strut bars and sway bars. I liked it a lot and was debating on selling my 300ZX TT to buy a new Z. I was thinking I could sel my Z32 for around $13,000 or $14,000 and use $5000 as a down payment on the Z, and another $5000 for the Turbo kit so that it would be a little faster than my Z32 is right now. I was wondering what you guys think and if anyone knows how much the Greddy kit puts down or where it might put me, say, quarter mile time wise for example. Thanks.

If money isnt playing a huge factor (doesnt sound like it does) yeah go for it, I think you would be extremely happy! I think the greddy turbo kits are putting down around 420-30 crank horsepower and I would say high 13's through the 1/4. I think it would be a great idea! DO IT! Nothing like a modern day TT Z car!
A:
I thought 350z's run high 13s stock?
I like the styling of the 300zx better, but those TT 350z's look and sound menacing too.

Yea the new Z is supposed to run 13.9's or so stock. No way would a Turbo kit keep me at that.

Sorry to burst your bubble, but there is simply no way you are going to get a greddy kit bought, installed and tuned for 5K. The Greddy is the least "out of the box" kit there is. In otherwords, you need really good tuning expertise and turbo install experience to do this one right. Because of this, it has the highest blown motor percentage of all the kits out there. Don't get me wrong, its a good kit, its just way more involved that buying the kit and bolting it on.

APS twin turbos plus test pipes and exhaust run mid to high 11 sec. qrs. at approx. 120 mph, on stock engine 350Zs. Easily puts down 500 hp at the egnine but best to build the engine if going over that (400 hp at the wheels) The kit is not cheap though. Cost $7495 for kit itself but is so very complete. (exhaust extra) Including the best fuel system on the market (fuel pump, 500 cc fuel injectors and fuel return system) in a stock forced induction kit. Quality all the way. Even has a bigger oil pan with cooling vents and a shielded crank angle sensor wire. Greddy will do fine but get an upgraded fuel pump and fuel return system which are not in the kit for optimum safety (without the upgraded fuel pump you are almost guaranteed to blow your engine - I know of over 15 blown engines with Greddy w/o a fuel pump). You simply have to have an adequate fuel system period. JWT kit is good but get bigger fuel injectors (kit uses the stock fuel injectors at higher fuel pressure which is not AOK by itself, IMO) and a fuel return system for optimum safety.
There is a fire breathing APS TT 350Z on 350Zmotoring.com being sold by bigbri putting down 700 hp at the wheels with a built engine for $45,000 and no engine problems he says:

Yea. I didn't know the Greddy kit would be like that. I know that every kit requires tuning no matter what, but I found out that some companies like turbonetics make singe turbo kits that puts down more than the greddy one by far. But I dont know if a twin turbo kit would have less turbo lag compared to the single kit being that the turbo would be bigger on the single.

TT has less turbo lag than the way the turbonetics (TN) single T is set up. With TN single T you have a crossover pipe funneling the other 3 cylinder's exhuast into one common flow with the 3 cylinders nearer the turbo and all this goes to a remotely located turbo located where the factory air cleaner used to be. Much more lag and less quick throttle response. But works pretty well but I just do not like all this extra piping/plumbing convoluted setup if you want quick response in curves and such.
You also have less lag with the APS turbo itself, the latest tech dual ball bearing turbo compared to the older technology single ball bearing TN setup. Both get the job done, though.
Now some people want turbo lag for several different reasons and like that one great rush of power with a single T. I like that also but like the quicker virtually instant TT response even more. To each his own.
I do not like the TN single T kit having the turbo where the factory aircleaner was in that you now have a lot more heat in the engine bay. I do like the TT setup in that you have both turbos located right there next to the exhaust manifold on each side of the engine for instant resopnse and less tedious plumbing. With the TN kit, also better to add a fuel return system if you go TN. The Z32 TT and even my old very down market mitus eclipse gsx turbo had a fuel return system. There are good solid safety and reliability reasons why Nissan and mitsu did that. I have heard too many really elite mechanics that will tell you you need a fuel return system on any forced induction with a 350Z.
The other big thing about the APS TT is that it is setup to take you well beyond the power limits of the TN kit if you want to build your engine. The APS kit is solid in all respects up to over 600 hp at the engine with a built engine bottom end. Well after the TN kit runs outta breath. Add bigger than the 500 cc fuel injectors in the APS kit (which are already bigger than the stock 330 cc injectors) and the APS TT will go well higher than that in power.
It just really depends on personal preferences though. My main beef is that the other kits seem to skimp on the fuel system in order to hold down costs and APS provides a very robust fuel system in the stock kit. It is very unsafe to run a less than adequate fuel system.
Oh yeah, the other thing I don't like about the TN kit is that all you get is a "one size fits all chip reflash". That is like tuning in the dark because all cars even of the same make and model run a little different. That is far inferior IMO to APS dealers real time tuning of your car at over 160 engine load/rpm points on a load based dynamometer. Via the unichip in the APS kit that piggybacks the factory computer. Here is some info on why that is much better. Gets more power and much safer:
This will tell you why you need a fuel return:
Be careful as all the kits other than APS tell you their kit's fuel system is safe as is and they are not. Upgrade the fuel system if you get a kit other than APS and you'll be ok (up to a point). I would not run a kit that did not allow real time tuning (i.e., TN chip reflash).
You will pay a little more with APS but it is a complete kit. By the time you upgrade the other kits, in almost all cases you will have spent more than the APS kit. I like APS cause I do not like mixing and matching different components of differing manufacturers in order to get a complte kit. Sharif has a Greddy kit upgraded with all the right stuff and his 350Z is a fire breathing monster! Either way works, but get your system complete one way or the other if you want to give your engine its best chance to hold up with forced induction.

Below is the kit I like. It is the best forced induction kit for 350Zs period as far as quality, safety, completeness, power/reponse, and price:
A:
APS 3" inch exhaust for APS TT 350Z kit. (The APS 2.5" test pipes into 2.5" exhaust is all you really need up to 600 engine hp, but the 3.5" test pipes into 3" exhaust really rocks but is kinda loud, he he.)
underneath view, APS 3.5" test pipes into 3" exhaust:

I forgot all about Greddy and Turbonetics when APS arrived on the scene. Kinda like comparing an old 1960's F4 Phantom to a F15 fighter plane.
F15 Eagle. 460 plus air to air victories (world wide), zero air to air losses:

In answer to your question, though, the APS twin turbos together put out more air than the TN single does. The APS turbos put out 41 lbs per minute each or 82 lbs/min combined. Now this is enough turbo boost capability to take a 350Z up to 800 engine hp. Plus Garrett bills the newest technology dual ball bearing, oil lubricated, and water cooled turbos in the APS kit as "the fastest spooling turbo on the the planet". IMO, the Greddy and Tubonetics kit is not even in the same league as the APS TT. Not even close.
