Hi guys, I'm new on here......don't have too much experience but here goes..... Thinking of swapping a B18c4 into my 93 DelSol, which already has d16z6 in it. I think the B18c4 isn't used in any USDM car, is this true? AFAIK, b18c4 is OBD2, is it recommended to swap for OBD1 (or go Hondata or similar)? Will I have any problems with driveshafts or ground clearances (already dropped 2")? I realise I will need different mounts, but any extra possible pitfalls, problems, tips or recommendations would be appreciated! The b18c4 seems like the favoured engine for the Japanese tuners! Apparently, Tatsuru Ichishima states that this is his favourite B series engine. And the B18C5 comes a reasonable second best.
