Hi
I'm new and old enough to have fathered the lot of you, so don't be to harsh on me.
I have a b20a5 engine that has been rebuilt by gude performance and will be putting it in a 1990 lude that has a b21a5 engine. It was suggested that I upgrade my obdo ecu to obd1 which I purchased 3 yrs ago.this is a pr4 a61 which is obdi from a 93 acura. My concern is it is for a auto trans. Should I be concerned? Another concern is the fuel rail and injectors. I was told that my stock injectors and rail should be changed and the distributor too. This motor has ported cylinder head, high compression radius cylinders &valve grind, ported intake manifold, ported throttle body, ported header &stage 1 cams This is a long block? that is ready for installation, I think. What parts will fit from the b21a1 to this engine?

thanks
