Hello,



fist off I have a 1988 rx7 which I've swaped in a 13b-RE engine I've been laying piping for the front mounted intercooler and I've run into an issue with the S4 AFM the thing is too big and I don't know what to do!! Should I convert over to the smaller S5 AFM? currently I'm using the cars original ECU to push the engine with plans to later upgrade to a stand alone system (but this is down the road..) right now I'd just like to be able to drive the beast...



Please any good advice would be appreciated..

Plumb it somewhere between the fmic and the TB. This way, open atmosphere BOVs wont affect air metering. It may even be more accurate.



What TB elbow is that on there? Its not the original Cosmo piece.

Actually it is the original Cosmo piece that's been rotated and reworked.
