Title: fd roters in a fc
Post by: billybobbooth on April 21, 2011, 07:31:26 AM
I know the fd engine isn\'t a direct bolt in but do the fd roters fit into the fc housings? Not that my engine needs rebuilding but going to buy the parts so when it does i don\'t have a big 3k bill. But i know the fd roters have a higher compretion ratio than the fc. If not ill just buy new fc ones. My plan is to get new housings and roters and oil pump and then use the other parts from my engine. So i can get close to brand new with out too much cost.

Thats what my bridgeported engine has in the Garage, its got FC housings but FD rotors, see if you can get some series 4 FC rotors, those had lower compression than the series 5 rotors, also make sure you get the FD corner springs not the useless FC wire ones lol

FD rotors and FC Turbo II rotors are the same (some later FD ones were clearances but still the same fitting and comp), series 4 turbo (only jap import in the UK) have lower compression. Series 5 non turbo rotors are higher compression.

Make sure you get the FD corner springs, they are much better than the random bit of twisted wire the FCs have as standard lol
