hey i love this site i've been glancing at it while i had my qr25de ...but im a 240 newb and im woundering what should i do when i buy my s13? im planning on leaving the ka for a while but then im going to swap a sr20det so does any one know any interchangable parts? ..well i was thinking about apexi n1 cat back for my first ...

 

www.SRswap.com is a good place and will give you a lot of info

This site is helpful as well http://www.sr20detinfo.com/2003meet.htm

The exhaust is interchangeable, the MAF, the Tranny(I forgot if you need to change the bellhousing)...Maybe more...I cant remember off the top of my head

 

what about an apexi filter??? >.<... im dumb

 

The filter itself, sure. Most filters are pretty much universal
