I'm doing an engine swap and i know it would be easiest to just use a 87-88 13bt but i want more power, but if i had a fd ECU, fmic w/ piping, motor mounts, and the 13rew would that be all i need???



along with exhaust, intake, boost control, timer, etc... i should make OK power i think..

 

why would you bother with the fd ecu? get a power fc, the s5 is very close to the fd

huh?? wouldnt the fd ecu be cheaper? control the engine w/o tuning, and be a quick performance upgrade? *shrug* and cant the 13rew handle 600+hp where as the 13bt looses reliabilit around 400hp unlss modified/rebuilt which would equal Mas Denero????
