1985 Pontiac Firebird 2.8MPFI

Hey guys, my car is an 89 Trans am l98 350mod...... blah blah blah anyways, i have a question, i just aquired an 85 Pontiac fuel injected 2.8, beat to hell with a very nice motor, i have an 85 GMC jimmy 4x4 carburated, my question for yo is what exactly do i have to do to make the efi motor go into the jimmy, what is the fuel pressure spec on the pump, if i can interchange the tank i will, if not do i have to run a return line into the existing fuel tank, and replumb? i would then have to get an aftermarket electric fuel pump, So for anyone who have converted a carbed 2.8 to an EFI multiport then I would appreciate any available information. Thanks in advance matt manglos

 

The pump setup would be the same as if you were cramming a 350 TPI into the Jimmy, so maybe you could search the net for info on that. The pump isn't the same though, same max pressure, same size, but the V6 pump flows less than the V8 pump.

As to the motor itself, you'll need to swap the computer and main engine harness as well. Don't know much about the rest. Karl (KED85) has an S10 blazer and might be able to help you out more...
