    after a 4 year battle with social security, they finally approved my claim. now, i want to build my jeep with the back pay.
    i was going to put the 200hp turbo v6 in for its fuel injection and ease of bolt up, but i have a 72 buick 350 sitting in storage. since i am swapping to yj springs, itll just need an extra leaf for the added 50lbs or whatever. i can put one of the newer FITech kits on it so i dont need a return line and set it up that way.
    9:1 pistons with an rv cam and it should move the cj6 around nicely. or i can keep the 2bbl intake and drop the howell on it as well and not have to pay that $400 for the 4bbl intake from ta performance.

    due to the saginaw style steering, the rods run beside the exhaust and wont allow a rear exit on the drivers side. so they have 2 passenger side manifolds on it (i dont know if thats factory or after market) but with the turbo, the pipes would have to be run crazy i think. with the 350, just swap the exhaust right and left and have front exit on both sides. then down and under.

    maybe have the odd fire flywheel rebalanced for that instead of the even fire.
    so the new idea would be"
    buick 350 FI
    sm420
    dana 18 with over drive
    dana 44 with lockers, 4.56 (with jk gears) and chromoly axles
    sittin on 35's
    and a 1/2 cab.

    thoughts?
    i also have a 78 even fire small port and the offenhauser dual port intake. that would be a smoother running v6. bolt in. with a holley 470 truck on top. would all need rebuilt, but hey..

    That's a solid parts list either way. Biggest question is always what do you really want to do with it, how much time do you want to spend on it and how much do you want to spend? Every time I get giddy with ideas I remind myself that plenty of go devils and ndt's made it over the Rubicon before a spring lift existed.

    i want a jeep i can drive on the street. i dont mind it being rough or noisy. im a "functional or beauty" type of guy. i just got my social security approved and 4 years of back pay coming. i want it built right and strong for moderate trails.my wife and i both have bad backs, but want to do trails and 4x4in to take pics or prospect/gem hunt. maybe take it hunting if i can find a lease or something. but i would drive it daily.
    thats why i am wanting fuel injection. ease of starting, tuning is automatic etc. take the turbo v6, its FI, smooth, bolts right up and has power when i need to pass. its the first gen so it doesnt have gobs of power (less than a normal v8), but itll get good mileage. turbo when i need for mud, or just keep it below spool rpm and cruise. call it part time v8 power.

    i think ill put it in and route the wiring. i have the whole harness and computer, engine with the turbo plumbing, trans and t-case that i need to clean up and put in it. ill need to setup the gas tank with a return line. it has the normal under seat tank, plus a 19 gallon reserve tank. once it gets going, it should be fun.

    i really want to go through the rubicon and moab. i want to hit the good trails of the US and maybe canada or mexico or something. im not looking for 42"s or anything crazy, just good flex and 35"s.

    but with our backs, we cannot afford to break on the trail, so i wanna over build it for security, then baby it on the road.

    Trying to make head or tails out of your thoughts. See your wanting to run 35's and be reliable, that is pushing the limits of a Dana 44. Even with upgrades, your starting to get into the 1 ton axle range with that size tire, and yes I know there have been a lot of rigs built with 44's and 35's. Myself I'm going to run 33's with a Dana 44 front axle, with a good limited slip differential. I'm afraid with a locker in the front with a Dana 44 and 33's I'd be snapping parts. Not really a fan of 1 tons under a little CJ myself but, lot less likely to need trail repairs than the Dana 44 Down side of the 1-tons is they do reduce ground clearance, and add a lot of unsprung weight.

    As far as the motor goes, I'd go with as little extra wiring as possible. Probably go with a HEI ignition and a stand alone after market EFI. Don't know a lot about turbos on gas motors so I have no opinion on those. V8 vs V6 myself I'd probably do a V8 but, built right and geared right the V6 would probably be good.

    As far as the SM420 with an add-on overdrive, myself I'd go with a modern 5-speed OD manual trans.

    Don't forget good high back suspension seats, your backs will really appreciate them!

    Not sure what your build budget is. But, for ultimate combination of fuel mileage, off-road crawling power, and reliability. A new Cummins crate motor backed by a modern 5 speed trans, and a Atlas 4 speed transfer case would be the ultimate setup. But, also the cost would be nearly where my entire build cost might be!

    well, the over drive is in the dana 18.
    budget? hmm. ive been kicking around the thought of tons/portals and linked suspension. but then it would become less a street compatible jeep and more trail only.
    not going cummins. if i have to get in the mud somewhere, i dont wanna pop out in china. ive seen some of the new smaller diesels in jeeps tho...
    the v6 it came from the factory with had 140hp/160 torque at the engine. the v6 turbo replacing it was conservatively rated at 200/300 net. itll have enough power when i need it. no turbo when on the trails, only when needed (passing or whatever). and, its the same engine as factory with tons of upgrades.

    ive been trying to look up the nv4500 conversions but they dont make an adapter for the dana 18 unless its an early (92-95) chevy 4x4 trans. those are pretty hard to find. if i change my dana 18 to teralow, ill have like 107: crawl ratio, plus over drive for the hiway. i have the cj6 so wheel base isnt an issue with longer transmissions, its just finding one with a low first for the rocks. sm420 is what i have, sm465 which would give me access to newer transfer cases but then i would have to swap rear ends.

    right now, its all up in the air.
    the 68 cj5 is the one that needs the 420 because of its length. thats why i have been kicking around the idea of going with something new on the cj6.

    im wondering about finding a dodge v6 and putting an nv4500 behind it (they are everywhere) with a 231/231 and making a good trail/rock rig out of it. however, i dont know much about the trans patterns on the dodge and even if it would bolt up or how to adapt the shift linkage/pedal setup. i wouldnt doubt the power of the modern v6's. they push around full sized pick ups towing trailers. that would give me 186:1 and would drive quieter than the noisy d18. either 69:1 or 186:1 when doubled up. assuming it would all bolt up...
    i am just at a loss.
