I/C piping
 

Alright so now I have this huge cheap-o ebay fmic, and i was wondering would a s13 piping kit fit the s12 body (the engine is ca18det). I had a friend of mine come over with his s13, i does seem that it should fit...
Has anyone ever tried?

it wont fit unless u modify the piping and maybe even the car, alot.
better is to build new piping, main thing is that our trottle body outlet is over the top and not front mounted as on the ca18det.

When I put the FMIC off my Silvia onto my S13, 90% of the piping fitted.

I think you'll be ok with most of it, but I think you'll have to cut a big hole in your battery tray, cut off the tow eye and cut a whole in the flat peice of metal on the right hand side of the engine bay (parallel with the battery tray.)

Other than that, its just dealing with the throttle body. I'll see if I can dig out any photo's. Good luck.

I have swaped the ca18det engine in my s12, so the throttel body is in the right place.
And well cutting the two holes is unavoidable with fmic, so i have no prob with that (the battery is in the back already, and the tray is gone).
Pictures would be real helpfull ;)
