2.8l cherokee motor performance questions

[Kennard_Mudder]

Ok, so i searched around and there were some tidbits of knowledge, just not all the answers i wanted/needed.

Ive got an 86 jeep cherokee with the 2.8l motor. Before i bought the jeep the motor was replaced with a new block and had a comp cam installed, along with an edelbrock torker 2 intake, holley 4 bbl carb and a K&N air cleaner. It runs great and ive had less troubles with the v6 than my buddy who has the 4.0, so swapping would be a step backwards in my book. I just ripped my exhaust off (not by choice either) so im thinking about headers, and in my search i found these http://store.edelbrock.com/688021984...he2and4wd.aspx . has anyone used them? also what else can be done to this motor to give it more torque/power. ive seen threads talk about high horsepower 2.8s, just never the setups or the tricks. i have plenty of garage space to do 99% of everything and have access to lathes/mills and their operators for free.

The Edlebrock headers are designed to work with that manifold and compliment each other. They are designed for the S-10 but may also fit the Jeep. Trying them is the only way to know.

i just got off the phone with both some jeep friends of mine and an edelbrock person, both said the kit will work with my jeep. Guess thats a good thing. now i just need to get the cash together and purchase it before they sell out!

[geoffinbc]

Oh LOL I didn't see that they made a Cherokee specific set. Well obviously that will work well.

I never even knew they put a GM 60 degree V6 in a Jeep? That's different... learn something new every day I guess.

i can tell ya for a fact heddman long tubes for a s10 4x4 won't work on a cherokee

[Kennard_Mudder]

voice of experience i assume?

im probably gonna go with the edelbrocks, just because they are designed for the cherokee and because they are on clearance.

[Kennard_Mudder]

Still havent gotten my order in yet. Had a small mishap with a deer and reconstructing my jeeps face... But im probably going to go with the headers after christmas, a nice prerunner bumper soon after, and a 3-4.5 inch lift. Anyone got any advice on making this things sound mean exhaust wise? I currently have an "ultra flow" cat, its like its "not there" *cough*, and its got a good sound, just not enough throat or cackle. I dont know if it works on these motors, but back when we used to do exhaust for v8s a trick for cackle was putting the muffler closer to the front end, the longer the pipe the more it cackled...

[geoffinbc]

Man put the cat back in. If you really want the exhaust to rip then run a descent cat and no muffler and 2.5" pipe.

[Kennard_Mudder]

eh its beat to hell. and currently, its sittin at 300 for a 1/4 custom built bumper with a stinger, or part of that for a cat. I dont have a huge amount of spendin cash, so thats why i go with on sale stuff.

yep, got mine super cheap off a guy that tried them on his and found out the hard way.

[Kennard_Mudder]

well if you still have the cherokee edelbrock is down even cheaper. i picked up the ceramic ones for 118 shipped, well, that was with the free shipping coupon that came in my catalog.

[neo71665]

No xj in my stable, thats why I bought the s-series headers.

[Kennard_Mudder]

ic ic...

got the headers in today. ill have to install them tomorrow. for some reason our little forced air heater doesnt want to keep running... gotta fix that before i go for the headers

Cool. Don't see too many built up 2.8 equipped XJ's anymore; they all opt for the 4.0 straight 6. Looking forward to following this buildup. Late.
