There are slight differences in the 2 motors, but not for your tuning purposes....just use the b18a ones.

There have been differences over the years.
The 1g B18a is from the 90-91 tegs. It has 130hp.

in 1992 the 2nd gen b18a arrived with 140, due to bigger cams (more lift and duration), better exhaust and intake manifolds. The trannies are also different.

In 1994 the b18b came with better head design (coolant passages changed) and different intake manifold again. 142hp officially. (tranny changed again)

Basically, the same motors, but there are differences.

Basically yeah that it's. but don't forget the cams, my orginal 91 B18A cams were a good bit different than a set of 94 cams I installed.

Also the ECU Chages affect power output in a minor way
