what is the differance between a 1st gen b16a and a 2nd gen b16a?

2nd gen is obd1 and 10 more hp.

yeah but is there any differance in the internals or is it just in the ecu

cr is up .2 from 10.2 to 10.4

cool thanx man but as far as u know r those the only differanes our r there more

as far as i know that is the only thing. cams might be more radical but i havent seen any facts on that
