wrpoole Posted January 25, 2013 Author Share Posted January 25, 2013 havent picked gear ratio yet or turbo size also add a rail shifter for the aw4 Link to comment Share on other sites More sharing options...
mnkyboy Posted January 25, 2013 Share Posted January 25, 2013 I don't follow. A 14b is a turbo size but yet you don't know what size turbo yet. Link to comment Share on other sites More sharing options...

mnkyboy Posted January 25, 2013 Share Posted January 25, 2013 That makes more sence. A 14b is either a mitsi turbo or a Toyota diesel engine. So your gonna turbo the 2.5l then Link to comment Share on other sites More sharing options...

mvusse Posted January 25, 2013 Share Posted January 25, 2013 I would start with a 4.0, and add a turbo to it if you really want that. Currently in the process of fitting a D60 under the front. Not as simple as it seemed. Thought about a 14b in the rear, but too big and don't want to spend the money to shave it. Opting for a Sterling 10.25" instead.

mnkyboy Posted January 25, 2013 Share Posted January 25, 2013 Ive been considering that on my 2.5l too. Link to comment Share on other sites More sharing options...
wrpoole Posted January 25, 2013 Author Share Posted January 25, 2013 well i was able to acquire the axles for $300 together and the manche for $400 in great condition then the aw4 and trasfer case for $200 when i start my build thread i will be doing it for bottom dollar everything Link to comment Share on other sites More sharing options...
jimoshel Posted January 26, 2013 Share Posted January 26, 2013 My idea. Take a Mack 3500. Remove the cab. Install a MJ cab. Don't have to mess with swapping axles, transmission,etc, etc. Link to comment Share on other sites More sharing options...
Alexia Posted January 26, 2013 Share Posted January 26, 2013 If you can do the turbo for cheap then go for it. The electronics for ignition and fuel control get expensive. Link to comment Share on other sites More sharing options...

ftpiercecracker1 Posted January 26, 2013 Share Posted January 26, 2013 If you have the $$$ to actually do the things you have planned I have a very hard time understanding why you would want to keep the 2.5. Even turboed it probably won't be more powerful than the 4.0 or even close for that matter. Link to comment Share on other sites More sharing options...
mnkyboy Posted January 26, 2013 Share Posted January 26, 2013 A 4.0l puts out around 135hp at the wheels a 2.5l turbo can put out 180-200hp at the wheels fairly easily. Link to comment Share on other sites More sharing options...
gogmorgo Posted January 26, 2013 Share Posted January 26, 2013 yes... but to get that much out of it, you need to completely rebuild the thing. You're effectively doubling the output with those numbers. The original internals could support a mild turbo, maybe seven or eight psi at the most (and that's really pushing it), which might net you an extra 30-40hp, but to get 200 at the wheels, you're looking at more like 20psi. Don't expect that to last too long before kaboom. Link to comment Share on other sites More sharing options...
mnkyboy Posted January 26, 2013 Share Posted January 26, 2013 8psi would give you a lot more then 30-40hp. Link to comment Share on other sites More sharing options...
mountainman Posted January 26, 2013 Share Posted January 26, 2013 I can see both sides of the coin here as i build high HP imports. It would be a cool thing to have, but the problem is i don't know how strong or efficient this 2.5 is. To get good solid numbers from it, is going to be quite a learning curve. What cam to match the chambers it has, and what rods can you get that will withstand triple the stock stress load. I think for wheeling and crawling youd prob be better off with a 4.0. Since it IS the displacement your attempting to create by putting a turbo on the little 2.5. When you need the torque and that big crank to bump something or to crawl up a steep @$$ rock bed at 1500-2000 rpm, you won't have it. Youll have a little gutless 2.5 that only makes a decent number when its on boost. So you will have to mash on the thing all the time and that doesnt work well in crawling. Rock bouncing and mud pits sure. So it depends on what you expect from this thing. With tons and 39.5s I'm gonna guess granite grinder. So id pop in a JY 4.0, or if you live in a no smog county and have time, put an LS1 in it. But a turbo 2.5, too many IFs. Bunch of damn crap under the hood to come loose and go wrong, boost pipes and intercooler everywhere, building the engine so it can handle the HP, getting good management and injectors, then a clutch to hold it all, building wiring harness for custom management (none of this will smog anyways) and finally having a tuner who actually knows what they are doing, to tune this little sucker. Hope this helps. Link to comment Share on other sites More sharing options...
mountainman Posted January 26, 2013 Share Posted January 26, 2013 8psi would give you a lot more then 30-40hp. Yes, the rule of thumb is a properly sized turbo on any engine... 10 psi should roughly double the flywheel HP. Link to comment Share on other sites More sharing options...
jimoshel Posted January 26, 2013 Share Posted January 26, 2013 I think just the challenge, fun, of building an engine like that would be enough. Every time a discussion on 4 cylinder racing engines comes up I remember the old Indy Offenhausers'. Just hearing one of them scream past and I would have to go change my drawers. A man takes a 500CI engine, gets 500HP at the rear wheels. Big deal. A man takes 150ci engine and gets 500hp at the rear wheels, BIG DEAL! Link to comment Share on other sites More sharing options...

A man takes 150ci engine and gets 500hp at the rear wheels, BIG DEAL! thats kinda what I'm after cuz I'm kinda a big deal B) i do have a 98 zj that i recently blew a tranny in so when the time comes and the lil 2.5 does perhaps get blown up i would be able to swap it in from what one of the local comanche enthusiast said that the 2.5 motor in the jeep is the same as the turbo'd 2.5 shadow or daytona which is where this idea was born anybody know if this is true or not?

mnkyboy Posted January 26, 2013 Share Posted January 26, 2013 The chysler and jeep 2.5ls are unrelated. The only dodge that got the Jeep 2.5l was the Dakota. Link to comment Share on other sites More sharing options...
