ComancheFan1991 Posted September 30, 2015 Posted September 30, 2015 Is it possible to convert the 2.8 to Fuel Injection, and would it do any good? I know that GM did put TBI on some of their engines, but not the 2.8.
Strokermjcomanche Posted September 30, 2015 Posted September 30, 2015 My 86 S-10 blazer with a 2.8 had TBI . I had an 86 2door cherokee plow vehicle that had a fuel injected 3.4 conversion from a 93 Camaro with all of the fuel injection/ harnesses from the Camaro swapped over as well .
Crash Posted September 30, 2015 Posted September 30, 2015 It can be done. As stated already, GM had a few versions of the 2.8, 3.1, 3.4 etc from Carb, to TBI, to MPFI. However, it would seem to me that an injected SBC of any generation would be about the same work and have more gain.

Shoehorning a SBC into a Comanche involves a LOT of work, adapters, and then you get to deal with the cooling issues. Converting a 2.8L that's already in the vehicle to fuel injection, especially a TBI system, would be several orders of magnitude less work. That said, it would also be polishing a turd. IMHO it would make more sense to grab an injected 3.4L out of a rear-wheel drive GM car, with the injection harness, and swap that into the MJ.
