1st off u need to tell me what kinda car u have DX/CX = DPI HF/Si=mpfi
all the engines u will swap need to have mpfi.
hey man, B18a is a great engine, it has its downfalls but so do any other engine
B18a Great torquelacks hp after 3rd gear great 4 boost, obd0
B16a Great HP lacks torque, moderately priced obd0
b18c1 good hp and torque but expensive and obd1-2
i suggest going b18a or b16a, any B block will be alot easier to find parts for and much faster than any D-series block, but in our ef's this power requires more work than throwing in a ZC
for a b18a, u will need b-series into ef mounts, integra shift linkage and tranny, integra axels/intermediate shaft, integra clutch cable and speedo cable, as well as the motor. u gotta dent frame on drivers side, put in mounts then it all plugs into Si harness. for the b16a same proceedure but u gotta run a few wires for vtec. if u wonder about anything on theb18a swap, theres a list of me taking a guy through the swap
Here!
so read that and u should know much more about the swap.
