I have a 1988 GTU...and am currently having Tofuball port my S5 NA intake manifolds for me. However, with that setup, I will have aux ports, VDI, a bunch of rigged-up setup for an airpump/vac lines to run it all, and will need to tune for the sudden bursts of air as the RPM goes thru.


I also happen to have an S5 T2 LIM, and FD UIM laying around...and, my interest has been set upon this. I know the runners are mega-shorter, and the manifolds will flow a LOT more. Also, having the intake go on the cold side of the engine bay seems neat...I could mount a filter directly on the TB adapter, for awesome throttle response.


My question is...any experience, anyone? I'm at a crosshair, Tofuball hasn't ported my S5's yet, I could have him port these manifolds instead...help!

 

so you want a FD UIM on on your car? do a search if thats your quesion. ports are dif but anything works with time and money

 

No no, that wasn't the question. The question was more of a..which is better? :|
