okay, so I bought the 1991 prelude, it has a B21A1 in it, not exactly sure what's wrong with it, and I have the 1993 Acura Integra with a B18C1 I believe in it, the integra has some frame damage on the front, the hood, fender and front bumper is fubar, but the rest of the car is the best condition integra I've seen. should I part out the integra and save up for a B21? orrrr could somebody point me in the right direction to a B20 from a prelude, because I've been looking and all I can find is B20s from CRVs... also, I was wondering if anyone knew where I could get a cheap rear glass replacement on the prelude, since the back window is busted. the prelude is a 5pseed, and the integra is an automatic... any information/help would be mucho appreciated. +reps to whomever helps.
