GReddy kits take forever to hit the marketplace. Go to greddy.com-->products-->Turbo Kits.
They're still working on turbo kits for the 240sx and Integra GSR (from 1995!) so who knows.
Hopefully they will put a little more priority on making a turbo kit for the 350z though.

thats so true.....but i dont think they'll slack on the 350

What wheels are on that car?

2 things. first that would be 500hp with 2 turbos, wrx only 1. second, those mitsu turbos are bigger then the wrx to begin with. i think(not positive) the wrx sti claims 300/300 with 17.5 psi not your 20.

Greedy will never release this in a suitable time.

Sorry - besides - 14 psi is pushing it - that VQ ain't gonna like that high compression for its aluminum block. Say bye bye to reliability, longevity, and your warranty.

Everything must be put into focus... sure 350-400RWHP is great but at what expense? I wouldn't plan on doing it personally. I want to keep my Z at least 3-4 years without major problems. I'd be interested in a Supercharger with modest gains, solid reliability numbers, and at least a 5+ year life span on stock internals. If you want to add 6Gs to your car and drop resell considerable why don't you just take what you'd invest and go and buy something like a Z06.

The more you blast the engine the more you are going to pay...

Resell or Reliablity... take your pick.

you mentioned you would do a supercharger. either way you look at it, its still force fed. turbo can be tuned for modest gains with the same reliability as a supercharger.

3rdpower

Turbo with modest gains = supercharger. Why spend 6k and tons of head ache for a high spooling TC with plenty of lag potential?

It just doesn't make any sense to me.

You're going to spend just as much on a supercharger. Also, a supercharger is much less efficient, lacks upgradibility, and hurts your engine more than a turbo. A supercharger will quickly heat soak your engine, whereas a turbo with a large front mount will not. Either way you look at it, the turbo is much better, and that is why we will see twice as many turbo kits as we will superchargers. A supercharger has to create energy, where a turbo simply recycles it. People keep talking about a turbo decreasing the life of your engine. It is how you drive your car, and maintain it that does this. You can easily add a turbo kit to a NA car, and have no issues. If their were such problems, why would companies like Greddy warranty their kits. The problem is that most people who turbo cars do it for racing, and this is why their cars get beat up. People run too much boost, and don't allow the car to properly cool down before shutting off. I know from experience just how reliable a aftermarket turbo'ed car can be. The biggest thing that most people don't know is that boost is VERY addictive. Once you taste it, you want more and more. So, you buy a kit, run low boost, then buy a few more safety addons and turn up the boost slowly. With a supercharger, you can only buy a smaller pulley, and that usually just causes the blower to fail earlier than usual because of the increased heat. We always tell people about this at our shop, but people still want a supercharger due to the myth of turbo's being unsafe. Time and time again, those same customers come back 6 months later to buy a turbo because they are disappointed with their supercharger. Everyone has different goals for this car, that I understand. I just hate to see the myth of turbo's being bad perpetuated on this site. Technology has made these systems extremely reliable nowadays. If you are content with 300whp, then a supercharger will be your best bet, but realize, you cannot easily turn up the boost on that. A turbo can run just as safe with the same power, and then be turned up more when the proper safety options are added on. I will be happy with my car at 400whp, and I'm sure it will be just as reliable as the guy with the supercharger who I keep smoking at the track.

what do you mean by resell or reliability? and a turbo is still better in the future a company may make low compression pistons if not already and then you can run higher boost

I have a question, what produces a higher underhood temperature, one with TT or one that is SC? In my mind, I see the TT as two heatsinks that are dissipating heat into the engine bay. I cannot say much much for the SC except what others say that it builds up heat. But which is greater?

Monkey Man

Menehune:
SC produces much more heat. TT also has the advantage of a front mount intercooler to provide cool air.

3rd Power:
I don't understand why you keep talking about 14psi. The Greddy kit will push 6-8 psi at the stock levels, and that should be good for an easy 350-375 whp. NO ONE in their right mind would run 14psi on a stock engine and expect it to be reliable. I think I speak for most when I say that 350-375 will be plenty of power in this car. And that will be very reliable mind you.

Sorry for the double post

I think 6k for starters Lot more stuff has to be purchased correct?

nosuchsol

No PSI ratings have been verified by Subaru for the new STi. I would expect less than that as compared to engine size v. comparison to old STi - RUMORS RUMORS!! FYI, EVO runs spike boost of 19psi on it's 2l

nosuchsol

Question: Isn't the VQ35DE an open block design? That in itself can be crucial to the safe amounts of boost one could push. It'd be interesting to see how they strengthen that area up.

menehune

But then that's intake air. Centrifugal SC can benefit from intercoolers too. I was leaning more towards the temperature in the engine bay. I guess I wasn't too specific, my fault.

nothing a blockguard cant handle

Not quite.

1 bar is 14.5 psi
1 atm is 14.7 psi

1atm is about 1.01325bar. All from memory so sig fig's may be off.
