Hello,
I was wondering what the differences in the b18a and b18b were? From what I read the B18a puts out 130 HP and the b18b puts out 140HP. What in the b18b gives it more hp?

Thanks for any info

seriously search

 

130?

 

the 90-91 B18a had 130 and the 92-93 had 140. 90-91 id OBD-0 and 92-93 is OBD-1 slight differences such as the OBD. The B18b's exhaust cam is slightly better in lift but alittle shorter on duration, also the ports in the head of a B18b are a bit bigger as well

 

Thanks 4 the info.

 

and a 4-2-1 manifold instead of the 90-91 4-1
