bought a 1990 civic Gl a couple of months ago and since ive finnished my rx7 this week im finally going to start on it. but im stuck on what engine to get for it so was just wondering what you guys have done or heard about thats gone down well.
There are multiple swaps that have been done that work well in that chassis. The most common swaps are B series swaps. These come in the form of DOHC Non VTEC and DOHC VTEC motors with the latter being more expensive for complete motors. The B swap has been done to death so getting it to fit and even finding cheap swaps is very very possible. Another fairly common (although not as common as the B swap) is the H22/F20B swap. These motors are both DOHC VTEC motors. They are cheaper than some B swaps and when coupled with the B series tranny they are very very capable setups. Less common due to expense is the K swap. These are newer engines first found in the RSX. They use i-VTEC and are DOHC as well. They are still pretty expensive for complete swaps. Mounts are made for all of these motors and there is plenty of tech support online that will assist you in whichever route you choose.
