compatibility and model differences
 

OK i just have some quick questions about compatibilty of parts. Are all rotors example, fc n/a, fc turbo, rew, re, renesis, compatible and interchangeable? What a about housings? Also is it true that a s4/s5 lim can only fit on the matching s4/s5 block?

My only model question is, what gave the infini iv the extra 13 hp?

all rotors are interchangable, but have different compressions and weights......

i know about the compression and weight differences, thanks

well as long as it is a 13B based engine... you couldn't use 12A rotors in 13B housings.

yea i knwo thats why i said fc n/a, fc, turbo ect. in the question. What about the infini iv?

Infini IV is the same as any other S5 Turbo... the modificatiosn for additional HP were in electronics, and exhaust.

The 13B is pretty much like Legos, put what ever colors you want together.

what electronics?

ECU was tweaked.
