My 91 si

[BigT91]

I have a 91 prelude w/ a b21a1(hole in block) and i was wondering if any b-series motor would fit in the bay or do i need to buy mounts! i know that the b20b/z will fit no problem but i want either a b16 or gsr b18c mainly but the b20b/z will work

i also need a motor so much help is appreciated! thnx much

No, they won't. Absolutely NOTHING except for another B21 or a B20A will bolt into your car's engine bay. B16s, B17s, B18s, B20B/Zs will NOT work without custom fabrication...

do a h22 but you will be in for some work but the end result will be rewarding

But is that a completely bolt-in swap like a B-series is into a Civic? I know about the mounts, but I was hesitant to list it as a simple drop-in because I'm pretty sure it's a little bit more involved then that...
