XK89CRXSI

Hi I have a 89 crx si and I have a b20a3 block. I would like to know the best way to rebuild it. I want to do the engine now and do turbos, nos, headers, ect... latter. I have $4,000 now +my weekly pay. I want to know what's the best head, cam, pistons, ect... to put into this engine. Oh and what will be a good tranny to add on and change for latter. computer chips the works

First, the B16 is cheap, which is why a lot of people use it.

As for your block, you mean the B20a out of the older 2.0L Preludes? If so, I'm not sure how much help anyone can be for you, since that engine is the red-headed stepchild of Honda B-series engines.

sell that engine its not worth the effort as it has little aftermarket and potential

buy a b18a for $1300 and a mount kit and you'll get more power and the same torque along with a HUGE aftermarket support including any kind of forced induction, etc.

well the guy who had the car before me put a b16 into it allready
and now i have the extra money cuz some guy hit my car and i took him to court so he owes me a good bit

Better yet, sell the engine as it is completely useless in a CRX frame. The B20A used completely different mounts, and has very little in common with any other B series engine, thus making the swap a total custom job. Not to mention the rod/stroke ratio is even worse then the B18A. If you want the satisfaction of a 2 litre engine, buy a B20B or B20Z for the swap. Or, just build the B16 you already have.

Just out of curiosity, were you suckered into buying that B20A? I see a lot of people trying to sell those, pretending like they are the same as the newer -B and -Z engines.
