What is the most economical way to fuel inject a 1990 Grand Wagoneer, Edlebrock intake manifold, 3" exhaust system.


Asked by Oct 24, 2012 at 01:19 AM about the 1990 Jeep Grand Wagoneer 4 Dr STD 4WD SUV

Question type: General

Haven't looked at doing this since 2001.  At that time everyone seemed to want to use a GM TBI system out of a 90 GM 350.  Any new, easier, less expensive ways in 2012?

Nothing easier. Throttle body still easiest to convert to. Your other options are multi port, and that requires new heads...


Thanks for the info. Is the GM TBI 350 still the best one to use?


IMO, yes. Plentiful, easy to repair and find parts for, tried and true system.


Have you received a quote to have this work done? I bought a 1991 Grand Wagoneer a few months ago and am expecting I'll need to do it eventually.
