boost on stock motor

john buck · 11-10-2006, 05:44 PM

i was just wondering how much boost you can run on a bone stock 7m-gte. and also about how much hp can you make before the internals need to be upgraded. i did a search and turned up nothing. any help would be appreciated. thanks

Really anything -past 9 is pointless on stock.

Shim the wastegate and remove both cats and you’ll get 14psi just before fuel cut-out, goes like a rocket.

Both Cats...I thought thats only if you had the Cali model.

The UK 7M-GTE has two cats, one in the down pipe and one at the beginning of the main exhaust.(where the down pipe bolts onto the straight part of the exhaust).Providing the motor vehicle was registered before 1992 there is no restriction in removing them in the UK.

i tried asking this b4 too but never really got a straight answer

if u shim the wastegate
how much is still safe
considering the fact that the internals are stock
the fuel delivery system is still stock
most likely upgrades will be an intake and exhaust
how much can u push it?

Becuase of a few things:
1. If you have a stock headgasket say goodbye to that. You want more boost than 9_PSI? Buy a BHG.
2. You will hit fuel cut past this. (9 _PSI is a rough number)
