I have an 06 TJ X and was thinking of doing somewhat of an overhaul on it. I'm planning on putting in a 4.6L Boosted Stroker Long Block from Golen with a Supercharger Kit from Adventure Innovations along with a 3" or 4" Suspension lift. I was wondering if I'd need to install new axles with a higher gear ratio than what it currently has. Currently I have a D30 front with a D35 rear with a 3.07 ratio (stock)and no lift running 33 inch Duratracs. If needed I was looking at installing D44 axles in the front and rear with a 4.56 ratio. With the lift I'm debating making the jump to 35 inch Duratracs if not larger.
Basically:
Stock 06 TJ X
4.0L 6-Cylinder
6-Speed Manual
D30 Front Axle
D35 Rear Axle
3.07 Gear Ratio
33 Inch Duratracs
No Lift
TO
3" or 4" Lift
4.6L Boosted Stroker Long Block from Golen
Supercharger from Adventure Innovations
D44 Front and Rear Axles with a 4.56 Ratio
35 Inch (possibly larger) Duratracs
Sound like a good set-up to you guys? Or would it be worth getting a D60 Rear Axle geared at 4.56 also? Any other ideas?
I think the 3.07 is terrible now as it is. My biggest question is whether the stock axles could handle the Stroker and Supercharger in general, and if they could even be re-geared to 4.56. Or would it just be best to upgrade to front and rear to D44 axles? It's my daily driver, and it just doesn't have the power for all of the Interstates and Mountains where I'm from. At the same time, I take it off-roading a decent amount which is also why I think I may need to upgrade the axles.
What about the transmission? The NSG370 is only rated to 270ft/lbs IIRC. With that engine setup you are probably looking at 350+ft/lbs. It probably wont break if you regear and dont do clutch drops but that is 30% over its rating.
Hopefully I can get the Stroker and Supercharger in for December, the Stroker at the least. Most trails around me are heavy on the mud in spots. That's why I'm thinking of doing both D44 Axles at 4.56 instead of my current D30 and D35 at 3.07. Along with wondering if the pure power of the Stroker and Supercharger breaking them.
There's plenty of garages around here that only do a visual emissions inspection. I don't know how they get away with it, but it happens. Turn the jeep on, take a walk around it, "Okay you're good." That was the way my last Emissions Inspection went. I'm not too worried about it yet. I'm from Pennsylvania, northeastern part of the state.
If you mean visual plus plug into obd2 port and a brief run that is pretty standard but I don't think your proposed setup will pas the obd2 portion of that test so if you want it street legal you may want to research that a little more
I've never had an OBD2 portion done. I can try my luck. If not I guess I'd have to make some modifications or always swap in the old engine if needed, as much of a pain that'd be.
35"+ you will need 4.56 or more.
D35 will break, D30 costs $ to keep it strong.
You can spend $2k an axle for gears, install kit, diff covers, truss, CM shafts, rear discs, trusses, labor.
Do you need a new engine or just want a new engine?
Don't do both stroker and supercharger at the same time. Do the stroker, break it in, get it running and tuned right and then after 1000 miles add the SC.
Stroker also needs supporting parts- aftermarket headers, 2.5" cat back exhaust, bored 62mm TB, CAI, bigger injectors.
Add the SC and then have to retune again.
Does Adventure Innovations even make that kit and is it available?
If it was me I would spring for a Dana 60 in the rear because with that much power you're going to want larger tires (I would go to 37" maybe a little larger) but like stated I would stick with just a striker then if you still want to get the super charger. Gears will be a must and if you have the money I would invest in a d44 front and build that up. That's a big overhaul! I hope you do it so I can read the build thread! Sounds awesome!
I don't know if you are trolling with such a ridiculous post but I think you need to research and spend money on your current setup before jumping to something so extreme.
Why would he spend the money on his current setup when he is going to change the power plant?
Everyone always gets so butt hurt when a guy brings up an extreme build he wants to do. The OP is here to research like most of you are suggesting he should do. STFU if you are just here to criticize. Dude wants a badass jeep, let him build it.
I mean this in the most non-a**holelish way but I honestly think if you don't know the answers to those questions already you need to do a lot more research before you embark on this overhaul. Do you plan to do this work yourself?
The whole thing is just a thought. I have enough money laying around to be able to make it happen. But I know almost everything would have to be re-done if I got the Stroker. My biggest questions were if I should get both D44s or maybe a D44 front and D60 rear with 4.56. Thanks for the information about the supercharger though. The stroker should be all broken in by the time I get around to ordering that. Some stuff me and a couple friends will do ourselves due to them owning garages. Something like the Stroker itself and the Supercharger I'd have done by an actual shop in my area, or maybe further from my area. Whichever shop seems to be the best.
I have planned a similar engine build for my Eagle just because I want to keep it I6 for nostalgia purposes (I'd like it to run in the 14s just because there is a long standing joke that all Eagle wagons run 22s). If I were a sane person I'd be planning on a V8.
You're going to break absolutely everything behind that motor, all the way down to the suspension mounts, if you're planning to run 35s. My hope was 31s and not have to put "too many" D35D shafts in it before the lunchbox locker, AX-15, rear D/S, etc blew up. It will never see a trail and I would expect it to last about 5 minutes if it did.
I don't think you fully understand the type of build you're spitballing about. What have your past rigs and street cars been? When you say you "have the money" do you realize that my 4.0 head alone cost me $600 and that's one of the cheaper parts?
You did not say if this is for rock crawling, street lurking, what?. With all the money you are going to spend you might consider an AEV conversion that is ready to run w/V-8 engine. However if you want to do this (because it may be fun), then know that (as another poster said), you are going to break most everything in back of the engine. If Rock crawing the Dana 44 frt and 60 rear w/4.56 or 4.88 gears would work-depending on what trans you use. Also a HD transfer case with lower crawl ratios. If going that route then 35-37" tires would be a plus. I personally would not put a super charger OR a turbo charger-but to each their own.
This is much more of a street build, since there's practically no real trails around where I'm from. I priced everything out and it's pretty expensive, but that's why I figured I'd upgrade axles and everything before I get the engine, if I get the engine. But who knows, by the time that all comes around the Diesel Wrangler may already be out and I could just dump some money into that instead.
