Ive already bought a zc but from what I have researched there are 2 differant ones? there really isnt much claification on this...ie..zc does not work on the search engine here..so I ended up goin through 186 crx swap articles..great time...any how is there any real differances in the swap such as bell housings..wiring ect..from what ive read since i have a 88 si its pretty much a simple swap..I have done a few b16 swaps and there not too complicated with the right tools and all the parts needed so I want this swap to go as smoothly

 

There are 3 ZCs actually (well ones that bolt into the 4G chassis) and they are...

DOHC ZC
SOHC ZC
SOHC VTEC ZC

 

What 4th said and also the black top dohc vs the brown top dohc, if you have a dohc you better hope you got the black top. Give us some info on what you got and we'll let you know what to do.

 

well from what i can tell it the doc black top..I know its not vtec...and not the brown top that came out of the crx and as of right now I have a 89-91 si tranny

 

whats the diff between the brown and black

 

the brown tops fit into 1st gen crx's.

 

so the black top fits in the second gen or better

yes. i have a black top zc (well I'm assuming it was a black top- when I got it the valve cover was a polished valve cover- dirty as hell, but it was silver & not black

 

next thought are ls rods a direct swap...I have seen a few posts on it but it wasn't really a deffinate yes or no...from what I have been reading the rods are the main weak link in the enginge..and with a strong set of apr studs and rods with some good quality time on the dyno I should be able to run a little extra boost and still have some dependability
