Anyone see why this wouldn't work with 4.0's? Mopar Performance ECU Matthew

Thought I would toss up a pic of my MJ She got her summer tires on this weekend. 33" Wrangler MTR's. I know I'm a little early in the season but I was talking to ClassicXJ the other day and it woke up the slumbering beast. Still have some things to get taken care of but I think I can get it...

Hastings I like the looks of their valve seals vs the new (Chevy) ones that were mailed to me by the engine builder. The spring mechanism to hold the seal on the valve guide looks very flimsy. He also said there is no distinction between the exhaust seals and the intake seals -- Yet the mopar...

I estimate I've put approx 2500 to 3000 miles on my stroker. Today while driving home I had sudden drop in power and the idle became rough. Temp was exactly where it should be and so was oil pressure. I was close to home so I drove it. Let the engine cool off and then started pulling the plug...

Finally got approval to go ahead and order a front bumper for my MJ. I've been trying to get in touch with Terry via the phone numbers posted on his website with no luck whatsoever for the last few days. I sure hope he's still around as I have been salivating over their products for a long...

I was driving down the street and saw a friend of mine walking on the sidewalk. I blipped the horn and nothing happened. found that the horn was bad. (tried cleaning contacts/ground first). Replaced horn with new one and blipped horn -- nothing happened. Went through testing from steering...

I completed the first 500 miles on my Golen Stroker today. (I picked it up last Tuesday) I've been considerate and haven't asked too much out of it yet. On the way home this afternoon I noticed that my oil pressure was low. I pulled into a Jiffy lube as soon as I could. To my surprise, the...

I'm in a pickle. I was overzealous in my exhaust decisions for my Comanche stroker project. I have a Borla Header and Downpipe, Random Technologies Hi Flow Cat, 2.5" SS exhaust tubing with a Magnaflow Dual output exhaust with a tip behind the mudflaps on either side... (this one)...

Finally got my stroker fired up today! I haven't driven my mj in three months and I oughtta have it back mid next week. It sounded good today but my next stop after I pick it up is to drop it off for it's new exhaust :) Sorry everyone...I'm just excited. Matthew

I picked up a dana 44 rear axle today for an xj and part of the work needed is new brakes...basically everything... I was wondering if anyone has a complete overhaul kit? all parking brake parts, cables, clips, springs, guides, adjustable screws... I can't seem to find anything complete on...

I've got a line on an XJ 44. I want to grab it for my MJ. Is the width between the spring perches the same on either vehicle? Or will the spring perches need to be relocated? I know that the MJ is spring under vs the spring over on the XJ. Figure I can pick up this axle and rebuild it and...

I've been building a custom intake for my soon to be renix stroker. the air tubes I've come across are designed for the HO rubber intake which is straight, unlike the renix which have a strong bend in them. My question is about the location of the 'bungs' for the line which runs to the...

I recently ordered a bunch of stuff from them for my mj, new upper and lower control arms, their track-bar/mount combo, airtube etc. The upper track bar mount that they shipped was the wrong one. A quick phone call, two minutes of measuring and they shipped out the right one free of charge...

I've searched and haven't come up with an answer that is satisfactory to me, so I'm going to ask a gearing question. Here is what I can tell you... I have a 1990 Jeep Comanche with an AW4 with 120k miles and a blown headgasket. I have a Dana 30 and a 35 with 3.55's as best as I can tell I'm...

I'm in the process of getting a 4.6 liter stroker for my '90 Jeep Comanche. The builder can offer me either the newer HO head or an original head. I've searched but have been unable to come up with anything conclusive about the swap. Basically, can I put the 4.0 HO head on the engine, reuse...
