S4 NA into REPU HELP!
It's nice to see someone else doing a similar swap, I completed a S4 swap into my FB last spring and just got done doing a engine upgrade last week after the junk yard engine developed a coolant seal issue.

Wow that's pretty nice. Imagine that same setup in rotary truck, then imagine another similar setup in an FB. That's basically what I have in mind. 
How does it run and drive, by the way?

Got some updates. I'm gonna change to a light steel flywheel in the FB. Then I'm free to throw the MegaSquirt at it! I'm very excited!
This frees up a half decent 225mm clutch disc for the S4 NA in the REPU. All I have to do is pull the engine, swap to an RE-SI front cover (same as GSL-SE with the 4 port OMP for EFI), swap to an R5 or similar old school oil pan and install the clutch disc. Then it gets the N326 ECU and everything else!

So far I've test fitted the FC intake manifolds in the truck. The throttle cable needs work and I'll need to get some kind of hose between the AFM and the TB. The stock one is way too long for the engine bay.
