i plan on getting Turbo for my 2004 G35 coupe 6MT. I was looking at the Greddy twin turbo, but was wondering for those that have the Greddy TT for years now or any turbo. i heard that turbo will make your engine life shorter. How is the car? Also, i want to know what is the safest psi i can boost for my stock engine. can it take at least 8psi? the car already have 151k mile on it.

Aftermarket parts i have on my car right now is
1) HKS exhaust
2) NWP 75mm throttle body
3) plenum spacer
4) berk Catalytic

 

Just keep it as is, buy a corvette if you want speed. You need to build your block to not blow up the G with lots of power.

 

if i can afford a Corvette i rather just boost my G. im not a corvette person. Just wanted to boost it for fun, not serious racing or anything since its also my Daily Drive car all season. any useful info would help for low end boost on stock engine. i know the lower the psi, the safer it is but i dont want to run it to low cause it will just be a waste of the turbo. my range is 7-8 psi, i will go 6 if 6 is safer for stock. Otherwise, i have no problem upgrading my engine just to take 7-8psi.

 

There is a forced induction section. Search there. We won't forge feed you info about boost.

 

These are pretty beginner questions. Like you didn't even as a budget. And a decent non half *** turbo build is probably around 15 to 20 grand depending on if you can do the work or not

 

OP you will need to have deep pockets to properly turbocharge your G. Can't just buy a $3000 kit on eBay, slap it on and call it a day.

Also a good grasp of the English language would help:
