Quick question. for the years 88-91 crx/civic, is the si the only model that has the mpfi setup? and all other models dpfi? reason i am asking is because i bought a tb for an 88-91 civic/crx, off of egay for really cheap, and all it says was 88-91 civic throttle body. and it showed a pic of the back of the tb and it looks like it should fit the si intake manifold. i just want to make sure that the mounting holes line up. any input is appreciated. thanks
