Sooooo I was wondering, would there be any advantage to running an s5 NA UIM on my s4 6 port turbo? I know it adds 15ish HP if you go from s4 NA uim to s5 NA UIM (ON AN s4 NA ENGINE), but I'm not sure if the VDI and such would help on a turbo install. I have read up but I think it just made myself more confused. Would a s5 NA uim even fit on a s4 t2 uim?

Could someone give me a clear answer?

Thanks

Long and short of it is no. It won't even come close to fitting.

 

it needs the lim to fit.

 

ok thanks. Just wondering though, if you had the s5 NA LIM, and the S5 NA UIM, would there be any gain in power on a s4 NA-Turbo?

 

It's something I"m about to try on a supercharged engine... I'll post results

 

k thanks
