LMFAO u saw it in a 91 prelude cause its the stock engine in the 3rd gen prelude SiR 2.1L (technically 2.05L)

MY B21A1 in my 1990 prelude SiR is a blessing but generally the stroke eats away the piston rings which causes it to burn oil which is what it is infamous for. the b21a1 is most unique of all b series let alone honda engines. the head and manifold are completely unique compared to other b series heads and manifolds.

and if your looking for vtec no go. preludepower members have experimented with the b16 and b18 vtec heads with very minute gain esp for the money you put into it. we talkin 2g's to vtec it and its just a big no go. the engine itself if rebuilt (prob like mine cause it actually burned less oil than my accord in a 500 mile drive) <burned less than 1/4 qt> driving around town i dont noticeably burn any oil.

this is an infamous engine and should be babied. so turbo out of the question. and to put a turbo on it you have to build you own kit cause there are hardly any brands that make any products for the 3rd gen lude. but if you turbo it dont expect the engine to behave for long.

the stock car itself is sex on wheels and the b21a1 complements it flawlessly but the motor itself is the same hp and like +10 tq of an cb7 EX motor.

ur better off goin b16 with a +20 Hp over both the b21 and the A6 to begin with.

heres my baby V V V

I'd just say this it aint going to work in a cb chassis without modification. Its worthless to put in a cb anyways. With the money you going to end up spending just get a the dohc vtec like h22 or f22b.
