Ok new idea for the GST

[delta727]

Okay, after a lot of thinking....I dont want 400HP in the 99 GST anymore as I see that I would need to rebuild the bottom end and I dont want to. Now I would like to get between 250 to 300HP daily out of the GST. Can I do this on the stock bottom end? If so, is there a kit any of you all recommend? Or a particular turbo? I would prefer a kit but if I could get some help with the needed parts I would be okay I think. Thank You.

250-300 where? Wheels? Crank? You can get 280 out of the crank with the T25 with proper tuning. 280 to the wheels is different.

Look at a 16G or t-28 turbos. You will not be unhappy with either one until you get the need for more power.

Looking for 250 to 300HP at the wheels...and 16G or T28 how is the HRC 16G turbo upgrade kit?

You have a 7-bolt 4G63. providing you don't get crankwalk your engine is actually capable of producing 450 CRANK hp on a stock bottom end, as long as you have the proper fuel to accompany the boost, it is all good.

For you, why not get a 20G and a big FMIC, with that you'll get some lag and that is pretty good for a FF car. 6-bolt engine can handle even more HP on the stock bottom end, just make sure you tune the car and you can make ALOT of HP

good luck

225 at the wheels with the stock T25.. and Im sure more could have been made with head work and cams and what not

Im still waiting to dyno the Big 28 though.. hopefully soon..

I would go for the Big28 for your hp needs and being a 2g you got direct bolt-on potential.

Later,
