what did you have to do to make it hold up to 500trq-450hp?! Christ, I'd be happy if it made 250-275, Im gonna turbo my 4.0 xj, probally use a megasquirt for tuning. Ive had experience with turbo's and tuning with my cobra, But do you have any sugestions or tricks about the 4.0 with boost?
help!! i am going to build one of these as i currently buy jeeps that dont run and get them back on the street. i love these and would really like to build a 4.0 to show non believers whats up. can you give me a detail on how you built this? parts, machined, turbo......? thanks
what did you do with the computer to increase injector pulse width in relation to boost? I was thinking of doing this but dont know where to get a computer flashed.
I'm working on a turbo stroker. I have a turbo from a 6.0 powerstroke. Bored .060"+ it comes out to roughly 4.66l. Why the e-85? I'm planning on installing mine in a 2000 Laredo so I'm keeping my electronic ignition & fuel injection obviously but I'd have to get it reprogrammed for a different fuel. But if theres an advantage I'm all ears to suggestions.
@SpliffbobSmokeplants Its true you get higher octane levels with with 85% alcohol, but your fuel mileage drops through the floor. It runs cooler and works well with higher compression because it lacks the thermal output of straight gasoline. E85 would probably work well in a carburated application, but you will run into entirely too many hurdles to make it work with the Chrysler JTEC controller. Ill put another post up after this to try to explain it more in detail.
Since you have to make up for the lack in thermal energy in alcohol with more volume, you need a higher rate fuel pump, larger injectors and a way to increase the pulse width when running flat out at full boost. It takes a TON of E85 to supply enough fuel to a boosted engine to prevent a catastrophic lean condition. I dont know that you could manipulate the JTEC with enough false inputs to actually keep it from melting down. Sounds like a cool build, but id stick with gas to be safe.
what did you do to it? im guessing reswirling the heads, maybe porting, tuning, performance computer a few other things and the turbo. i'd intercool it to.
@09adge13 Chrysler had actually planned on continuing production of the 4.0L but they couldn't get the economy and emissions they were looking for with it.
the 4.2 has bigger internals like said, thats why guys sawp 4.0 fuelinjected heads on them, so its the power of the 4.2, but the drivebility/performance, fuel milege of the 4.0. i wish i never sold mine, time to find another, and turbo it. this thing sounds like a diesel!!! lol
Sounds awesome, and great numbers. I'd love to have a small turbo on the 4.0, but that's more power than I'd ever need. I wonder how a turbo would fare on the 2.5.
@DardeeChar It IS a good engine, and very capable of lasting well over 200K miles with regular service. Yeah, it's an iron lump, a smooth torquey, somewhat economical,reliable durable iron lump though. That engine pretty much saved the Cherokee from the mediocrity it was suffering with the GM 2.5-4 or 2.6 V-6 junk it was first on the market with. It's something that AMC really got right.
It shoved the stock 60,000 mile head gasket out at 15 lbs. And cracked 2 stock pistons. I built the header based off the stock one. Sorry, I will not be making kits or headers for sale. The engine is going in a 1979 AMC Spirit drag car. I have new forged pistons on the way. This is an on going project and I fully expected to break a few things. Shooting for 500hp with a cam change and the next test. Also going to E-85 fuel. Thanks for the interest!
@TurboAMC what rods are you using? you may want to consider lowering the compression either with the new pistons if possible or rod/crank, i assume your using arp head studs? have you experimented with the 258 block?
es muy importante for you to tell us your findings. What is the website? I have the appetite, i want to fight. I was not too good at tae bow but i certainly WANT A turbo!!!
did you have to custom make the exhaust manifold?and how much boost can you run on a stock head gasket?ive heard 5psi if you dont want to hurt anything
how much boost can a stock 4.0 handle?

@SpliffbobSmokeplants a lot of people with turbos are starting to use E-85, higher octane levels, makes it run better.

No the 4.2 has the longer stroke thats how you make a stroker by putting it in the 4.0 block.
