I bought an 85 gsl-se someone put a 12a in b/c they were broke....pretty hacked up job too. I want to go back to a fuel injected 13b....is there a difference in the 13b block of 1st gen and 2nd gen engines? I may have a donor car for the electronics and intakes etc, but the motor is shot. Could I put the gsl-se intake and everything onto a 2nd gen 13b block? Thanks.
