Just picked up a gsr teg. Motor is cherry but i want a little bit more hp. Had a boosted ef before and that car was fun until it got stolen. So i want to get back in the game and want to mess around with my teg. Has anyone boosted a stock block/valvetrain gsr before? If so what are your numbers and setup, size turbo, etc...

 

Lots of people have done this. I recommend searching the F/I forum for information on boosting stock B18C1 blocks and then returning with more specific questions.

IIRC 6-7 psi is the general limit of what's safe but I'm sure that depends on a number of factors.

 

Thanks for the input.

 

no such thing as "safe psi" 7lbs out of a gt35 is completely different than a t25

the general is that around 300whp will live for years if the engine is healthy.

push past 400whp and you're on borrowed time


there are a couple of inexpensive options that work well on the gsr

the garrett 50 trim in a .63ar $650

the precision 5431e in a .63ar $670


and the precision 3431e if you absolutely need to save that last $100 over the top 2

my personal choice of those 3 is the 5431e mainly because of the billet wheel

there is a gsr dyno thread in FI that is almost required reading for what you're doing

 

Thanks for the post. Thats exactly what i'm asking about. I ran a garret t3/t04e on my ef with the 60 trim. Good turbo. Well i shall see what i can afford for my car. Thanks for the input guys
