I could get it done real cheap throught a friend... but before I shell out any money, what kind of gains can I expect from this... he said about 10-20 horse is very possible, although most of the work he does is supras.

Thanks,
Luke

 

10-20hp sounds unrealistic unless you are running some major modifications on the stock IM. I say expect no more than 5hp tops. Also, how cheap is cheap?

 

stock intake mani is already optimized for performance...if you could get it better and worth the price, it'd be out by now...but the runners are already the right length and the plenum is the right size...so unless your are F/I or your looking to change your powerband...don't bother
