duster1971 Posted March 23, 2011 Share Posted March 23, 2011 Ok I'm new here and have ownd a 94xj before with 4.0 ho. But now have an 86 mj with 2.5 and was wondering if anybody has links or any thing where I can find performance parts such as header, cam ect. Thanks. O and a back window I got my mj for 300$ its ruff but I like it always wanted one but the guy I got it from let it go to crap so I need rear window drivers side vent window and drivers side miror. For mirors I think I may use the mirios off my 87 isuzu since the frame is brokin on it. Link to comment Share on other sites More sharing options...
jmderyke Posted March 23, 2011 Share Posted March 23, 2011 The internet is probably your best source but searching is involved. There are performance parts for the 2.5 I know mopar makes three different cams, yella terra makes roller rockers and also mopar, borla and pace setter makes headers and ceramic pistons are very easy to get from multiple companies. For some reason they don't list the comanche just jeep 2.5 or wrangler 2.5 thats why it can me a little difficult to find parts. Link to comment Share on other sites More sharing options...
duster1971 Posted March 23, 2011 Author Share Posted March 23, 2011 Thank you I will have to start looking into some roller rockers and a cam gona pass on the header for now and see if the turbo off a car I had with the 2.5 will work I have the whole setup minus the lines and the head considering the head is sohc and not an ic head.

What car did you have that used the Jeep 2.5L engine? And what is an "ic" head? Link to comment Share on other sites More sharing options...
jmderyke Posted March 23, 2011 Share Posted March 23, 2011 That would be nice to see an old mj 2.5 a turbo, but how will you tune it? I havent seen a fuel controller for our old pickups Link to comment Share on other sites More sharing options...
dasbulliwagen Posted March 23, 2011 Share Posted March 23, 2011 MOPAR no longer makes cams for the 2.5, and NO ONE ELSE Ive found makes them anymore either. Clifford performance used to have listings for 2.5 performance parts, but have recently done away with them all. Some say there are places that will regrind a new profile on a stock cam for a performance application, but I have yet to research any of them yet. The best bet for the feeling of more power in a 2.5 is gearing in the axles. Other things you can do are to do away with the engine driven fan and add an electric unit with a fan controller. Ive had good luck with opening up the exhaust, with a gutted and sleeved cat converter, and a Flowmaster 50 series muffler. Ive also done a "COLD" air intake tube, but I really only put that on there to make room for other modifications, and just because I had it laying around. Tune up parts will be the next best bet for better power, including a new 02 sensor. I don't think a turbo system on this truck would be worth the time and energy it will take to make it work. Youll just end up with a partially finished project that youll be unable to finish or make run right. We wish you luck though and let us know what you end up doing.

Ic is an abrevieation I use to describe internal cam or standard cam instead of overhead cam sorry for confusion. Link to comment Share on other sites More sharing options...

I havent seen a fuel controller for our old pickups Gona have to tune it old school before the electronic controlers. Done by getting air fule gauge and bosst controler got to watch make sure it dosnt go lean if it does turn down the bost I'm looking at probly 3-5lbs of bost so I'm leaning away from turbo.

Good to know about cams I did some looking and founs stock cams and a place that sells pistons in 30 over size. I got to figuring the same on turbo way unpredictable off road that and the boost I wuld have to run wuldnt realy show any grand gains and there realy is no replacement for displacment.

streetjeep2.5 Posted March 23, 2011 Share Posted March 23, 2011 I have an 87 2.5 Delta Camshaft Company that was in Tacoma Washington did make and as of 6 months ago still made a "performance" regrind. http://www.deltacam.com/ I have one in my 2.5. And, double the comment about opening up the exhaust. I have a free flowing CAT and a single in dual out Flowmaster. Did have a Clifford header that REALLY helped but it never fit right and I had to modify it. It's now gone. Link to comment Share on other sites More sharing options...

Just remember, it s 20 plus year old 4 cylinder truck with a bunch of miles and use/abuse on it. Take your problems one at a time, and fix them little by little and upgrade when possible and you can't go wrong. Link to comment Share on other sites More sharing options...

duster1971 Posted March 25, 2011 Author Share Posted March 25, 2011 I do not beleave the 2.5 trans will work as I think that year still has the gm bolt pattern on the bell housing. And as for keeping the comanche I say go for it you have 800$ in it now you said you like it know it or not you have alrready made up your mind lol. Its some thing bout these trucks they almost chose you instead of you chosing them. Link to comment Share on other sites More sharing options...
raviolli Posted March 25, 2011 Share Posted March 25, 2011 Its some thing bout these trucks they almost chose you instead of you chosing them. :agree: i never in my life thought i would ever even SIT in a comanche let alone own one but ill never forget the night i was at work and my girlfriend texted me saying her dad was gonna scrap his and told her she could beat it up in the woods. it was like fate...that jeep needed someone to save its life and i came to the rescue. just seeing a picture for the first time i fell in love with it. before then, never even cared for them Link to comment Share on other sites More sharing options...

streetjeep2.5 Posted March 28, 2011 Share Posted March 28, 2011 Was returning from being at the Seminary for 4 years and going to my first church and were at wifes mom and dad's place in Redmond Oregon when we saw the new 1984 XJ. We liked them. Didn't like the little engine offerings, though. Then, in 1994, bought a new XJ 4door 4x2 4.0 auto. AWESOME RIDE! Kept it until February of last year, 247,000 miles and really no trouble. Even only aligned the front end once. SOLD ON JEEPS!!! Found my used 247,000 mile 87 MJ 4x2 in Edgewood in Washington State in 2002. Had it ever since. Overhauled the 2.5 twice (2nd time the fault of ill fitting header), original rear end and tranny, and I think all front suspension. Changed steering gear (manual). BTW, traded the XJ in on a Patriot. Love it also! Uh, yea, sold on JEEPS!!!! Working toward a 327 in my MJ, maybe. Streetjeep, you know! Link to comment Share on other sites More sharing options...
duster1971 Posted March 28, 2011 Author Share Posted March 28, 2011 a 327 huh why not go for the 304 amc engin or a 318 both are bullet proof and run hard that and they are both amc/chrystler. Link to comment Share on other sites More sharing options...
