Ok here is the situation, I have a 98 civic dx and i want to swap in a si motor, B16. Now my question is which B16 will fit in my car. Everyone I have talked to has told me different things. Some people say go with the B16A1 its the cheapest swap, and then other people say that there is no way the B16A1 will fit in my car. So which motor fits and where would be the best place to get the complete swap. Thanks for the info.

 

in that car any B series motor will fit u just have to use the 99+ si mounts

 

all b16's will fit. its just a matter if you are getting a motor with a cable or hydro tranny. since you have a 98, you'll want to get a 2nd gen b16 with a hydro tranny(92 or newer) since your car is setup with a hydraulic clutch.
