would that really give someone 40 whp on a t-25 turbo????
and im looking for the most horepower for my car without upgrading the turbo any one have any suggestions on what to buy????

Why not upgrade your turbo? I'm sorry I can't give any input on the intake manifold.

it wouldn't give you any more power with the T25, you're not anywhere near outflowing your stocker. SMIM's are one of the last bolt-on's, if not the last in the upgrade path.

Id focus on upgrading your fuel system right now.

save the money you waste on that and get something that will help you more now. fuel, turbo, tuning devices, etc.

For $650 you could get a 14b, make your own install it, some 550cc injectors, and a S-AFC and make more power than you ever would on the stock T25 with a sheet metal intake manifold. Just a thought.

The reasion why it's just not worth installing an aftermarket sheet metal intake manifold is because of the flow rates of the t-25, runner desine of the intake & cylinder head speed volosity. The 2g head was designed for higer volosity/lower flow # becasue of the size of the runner ports. The t-25 has absolutly no chance of ever maxing out the flow limits of the 2g head. The turbo it's self is only usefull within its boost thresh-hold of 2600 and flow effenct of 5500. If you look at the mathamatical equations of VE and compare it to the Flow #'s of the head & intake you will see that it's impossable to out flow either. High speed volosity stacks, pendium desigine and port size is relitivily worthless at such a low rpm range of the t-25. You need a 14b

Hell just go for the 16g :D
