b18's are most commonly from integras, and the b20 that came in the early model prelude is a completely different engine. stay away from that b20.

Absolutely not. The B20A/B21A is completely different from all other B-series engines. Stay far away from it.

Depends on what you're looking to achieve and what your budget is.

well the b18a/b's and b20's have the same crankshaft so you wont accomplish anything there. but when it comes to the prelude b20, they are different from traditional b series engines so i doubt it'll work.

But why would you want to do that?

to me those old b20a5 prelude motors are garbage to me. if you wanted to go b20 do a b20b there cheap but the cylinder walls are weak though from what I have heard.

B20B/Z's have "weak" cylinder walls because they're a B18B block, overbored .2L.

I'd recommend the JDM '99-01 B20B or the B20Zx if he just wants to run a straight B20. It's a 20hp and 500 RPM difference.

If he plans to run a VTEC head, then as you said, might as well get the JDM '95-98 B20B or the B20Bx since you have to change the pistons . . .
