I'm trying to decide between all the turbo companies out there that make kits for the VQ35De. Could someone provide a list of companies that make Twin-Turbo kits?

I have already looked at kits from Greddy, Turbonetics, etc.. and I wasn't too impressed by the numbers. 140 HP gains from the Greddy kit doesn't impress me at all. I'm looking more for quality and potential to make horsepower, as I guess most people are.

I've heard JWT makes a kit too, I'll go check them out right now.

Feel free to let me know about any smaller companies doing TT kits as well, Thanks.

 

Greddy
Turbonetix ST
APS ST/TT
SFR TT
JWT TT

are the ones that immediately come to mind.

 

So a 60% gain in hp on stock internals on a non-fi car doesn't impress you? You might want to buy a subaru.

 

agreed, 140hp is respectable for any bolt on anything imo.

 

Shameless plug...

 

Sorry, I forgot PE - TT.

 

I know this is probably a very vague question..

Which kit has the most potential?

 

The SFR 60-1 hifi TT kit is capable of 1000rwhp. You will need to upgrade your injectors and fuel system and of coarse build-up your motor. You could also put this kit on a completely stock car and build your motor,heads,fuel system down the road. No need to upgrade your turbo or wastegates. On stock Z at 8.5psi on 91 oct. it dynoed 439rwhp and 449ft/lbs of torque, on stock exhaust, and plenum. Was told on stock G35 you might get an extra 15-20 ponies.

 

why would the G35 have an extra 15-20 ponies on an otherwise identical motor... is it because of the dual intercooler setup on the G35 system?

 

From what I was told by Tim at SFR, dyno # results are higher on G35's. Not sure why, give Tim at SFR a call.

 

It sounds like you're looking for APS perhaps? Let me know if you have any questions/concerns regarding their system. We are their major west coast distributor and we'd be more than willing to help you out.

 

Eternal Motorsports is a new company that's coming out with a single turbo kit sometime early next year, that i have on my car now. my car was used for test fitting and tuning. i'm running 383hp and 416tq at 9psi.

 

How is the car holding up? Have any good or bad impressions about the kit? I'm getting the same kit in a couple of months. Here is what's included if anyone is interested they are having a special on the kit right now. PM me if you want to know the original and special price.

I thought a 60-1 was only good for 650-700hp / 550-595rwhp max?

 

They're using 2 of them.
