mikron Posted January 24, 2015 Posted January 24, 2015 hello guys it's been a while but I still have my 88 Comanche sport truck. what I need is some info on a carb. my jeep is a 4 cylinder and I was told that there is a ford carb that is a direct change over. if anybody knows of this I would appreciate the help. love love love my truck and miss driving it
Strokermjcomanche Posted January 24, 2015 Posted January 24, 2015 Your 88 will be TBI ( throttle body injection) not an old style carb . Afaik I've never heard of anyone putting a ford carb on a 88 2.5
yxmj Posted January 24, 2015 Posted January 24, 2015 It was the 2.8 (v6) that you could swap a ford carb to.....The TBI in yours is pretty straightforward (I , and others on the site have them)....what is the problem?
Jeep Driver Posted January 24, 2015 Posted January 24, 2015 Impossible anyway. Without TPS feedback your ignition timing is dead. http://comancheclub.com/topic/45169-just-us-25-boysshameless-plug/?hl=jeep+driver&do=findComment&comment=459732

Remember, the 2.5L in the 84 and 85 Cherokees had a carburetor. So it can be done, but it would involve (I assume) not just bolting on a carburetor in place of the throttle body, but also converting the ignition system to the 84-85 system. You would also have to change the fuel delivery system, because a carburetor typically operates at about 7 psi (max), and I'm pretty sure even the TBI injection ran a lot higher than that.
gogmorgo Posted January 24, 2015 Posted January 24, 2015 It was the 2.8 (v6) that you could swap a ford carb to..... But... but... the 2.8 is a GM engine. You can't put a Ford carb on it. SACRILEGE!
Eagle Posted January 25, 2015 Posted January 25, 2015 yeah but it would probley run better. That particular carb was such a piece of ... "work" ... that you could do better just pouring gas into the intake by hand. Years ago I took one to the professional carburetor guy all the local racers knew and used, and he almost threw me out of the shop. He did finally try to tune it up, he only charged me ten bucks, and he said, "If it doesn't run, don't come back." It ran, but it was still a piece of ___.
