1991 cherokee, any suggestions out there on how to give her some more horses?
ive been looking into a cold air intake and a performance exhaust system, any suggestions on which of those have been working for people? or anything else that will kick her in gear? (yes... my jeep is a she)

Check the search feature to find similiar threads that go into more detail. but there is also a 99+ intake mod. bored out TB and injectors (more throttle response and fuel economy). Just to name a few more.

i have heard about upgrading injectors. i have a 96. what injectors can i pull out of a car at a junkyard to gain some HP?

strech117

i tried the search feature, couldnt find what i wanted. my abilities arent quite up to most of you guys. is 99+ the company name or am i missing something there?
do they make throttle kits? any idea what size injectors i can get away with without major modification or engine explosion? haha

year model is 99 and newer is what he means. chrysler redesigned the intake and made it flow better so you get better mileage and power.

right right, duh, it was a long day at work. would that maybe be a better bet than something after market? im more concerned about performance than price.

where can we find how to bore the TB?? I have searched and searched the write-ups and nothing.

KTMrider

As far as I know there are are no after market companies that produced intake manifolds. Just go to the local JY and yank it.

This is they guy i used, very happy with overall price and preformance gain. http://www.strokedjeep.com/tbody.html As far as doing it yourself, there is a write up on that. I will try to find that for you.

Some pretty long threads on that topic. I beleive the ford 5.0 injectors do the trick for that year. But i would get someone's else opinion on this that is more knowledgable before you go getting them. And it's more throttle response and MPG gains than HP.

very very helpful! ill be giving him a ring. where is he located?

strech117

i will be looking into that too. never replaced a fuel injector... cant be an easy thing to do. but i like the idea alot.

KTMrider

Don't remember, midwest some where i think. It was 12$ for shipping so i wasn't too concerned.

strech117

very cool, man. haha im across the northern border but i have a mailing address out of north dakota. how does it work? i have to yank mine and send it to him for machining right?

KTMrider

You buy his premachined 1 and then once you get it you send your stock 1 to him and he credits you back the money for the core once he receives it. Then he sells it to the next guy, and the cycle continues. Shoot him an email and he'll tell you what you need to do. Paypal works wonder in this deal.

fantastic, your the man. i dont believe ive ever worked on one, is it a doable "at home" project?
have you heard many good stories about people swapping out for newer intakes manifolds? im getting mixed reviews
