Im now leaning towards a CA18 instead of the SR20, but I wanted to know if the parts, (ie. turbos, downpipes, FMIC's, ect.) are interchangeable between them. I ask because I have only seen websites that sell parts for the SR. Thanks alot.

the actual turbo yes, but the maifold no. Need to buy a CA manifold. If you go with an SR turbo you will need to get a SR downpipe and frontpipe. the rest of the exhaust is the same.
IF the intercoolers are not swappable than it is an easy fix. The only place it wont fit is where it mates with the Throttle body. The turbo side will need to be adjusted anyways depending on your turbo.
You can use SR:
MAFM
Intake
exhaust
Flywheel
clutch - you must first install a SR flywheel
piggy back electronics (if it comes from japan, the wiring diagram will include instructions for CA's)

 

thanks monkey, if anyone else has any input it'd be appreciated
