i've owned a couple prelude's with B21 swaps and you cant even tell any diff. ! they run the same as the stock B20a5. not worth the money you pay for jdm!!! lol
i just bought an B20a5 from a guy in here a lil while back, and i'm about to put it in the car soon.
maybe i canmake you a deal on the whole car and motor.
it's a clean 91 si.
