I want to use 4 port turbo irons in a s5 NA, this possible? Tried searching but only came up with a bunch of what are the differences, I just need to know if it'll work.

 

The ideal thing to do is get a turbo engine and use the rotors and crank from an NA motor, preferably the 91. This, of course, would be maximized with some decent porting, specially on the intake.

What do you want to do with this engine combo?

 

Yes it will work, but you'll have to use the TII manifolds as the N/A LIM will not match up with the front or rear ports.

 

I'm planning a holley 4 barrel and 4 port manifold and a custom header, this is going in a bug btw and I'm looking for 200whp
