ive been doing some research on the 2.5l in all of it versions, there are several.
Here are some general VIN notes regarding the various 2.5 liter motors:
Vin V 1977-1980 Carb non cross-flow head (intake & exhaust manifold on same side)
Vin 1 1978-1979 Carb non cross-flow head
Vin 9 1979 Carb non cross-flow head
Vin F 1980-1983 Carb export only
Vin 5 1982-1983 Carb cross-flow heads from 1982 on
Vin 2 1982-1986 TBI Thrust brg length 1.009, Head bolt spacing 3.75
Vin R 1982-1992 TBI FWD/RWD/Fiero Thrust brg length 1.009, Head bolt spacing 3.75
Vin U 1985-1991 TBI N-car FWD Only Thrust brg length 0.940, Head bolt spacing 3.67
Vin E 1985-1991 TBI S-10, Astro Van Thrust brg length 1.009, Head bolt spacing 3.75
Vin A 1991-1993 TBI S-10 Thrust brg length 1.009, Head bolt spacing 3.75
i was wondering if anyone knows if the parts for the fiero are compatable w/ the vin E and/or A?
if its possible to take the distributerless ignition of the 87-88 fiero and adapt it to the s10? do i need the ecu from the fiero?
