It's a b20a5. The b21a1 was in 90-91 'ludes.

i see. i just worked on one changing the hydrolic hose for the clutch because it was all leaking at the fittings. i figured they all had the b21a1, that engines a clusterfuck.

I have an 88 that I have fabbed a kit for although it has yet to be fully tuned. I am running 6-7psi on a nissan t25, dsm 450's, front mount, and chipped pr4 w/uberdata. No need to touch the distributor it's already compliant. You will of course have to purchase or fab an obd0-->obd1 conversion harness. Check out www.preludepower.com as was mentioned above. Do lots of searching and you will find the answers to your questions.
There is a company making manifolds as well.
