A New Project

It looks like there is going to be Jeep project break out in Dallas, Oregon.

Last December something in the overdrive broke in my tranny so we have been limping along with other vehicles until the stars lined up better. Now the ZJ is parked in position and ready to start draining fluids and begin a serious tear down.

To me, it makes no sense to put a fresh tranny in behind of a 225K motor, so the engine will meet the machinist and the tranny get some serious thought. I have always thought that the ZJ would be a better rig with the manual tranny so I might end up that direction before it runs again.

I'm not a rock crawler or mountain climber so don't see any major lift work coming, but I would sure like to improve the factory suspension. The corner roll and break dive has always been a bit of a dissapointment. I drive a Saab and have wondered if four wheel disc brakes and stiffer sway bars on the jeep wouldn't be a solid improvement.

I don't see me spending a ton of money on the motor but since I'm going to be into it I think that the heads will get some polish time, I would like to find a better than stock cam, first over pistons and deck the head and it should be a solid improvement for reasonable expense.

Lots of work, lots of fun, if I could find someone else to write the checks I'd be in tall cotton.

ANY input on this project is welcome. Things like cam specs or anybody that has experimented with injector options, rear disk brakes or manual tranny conversions please chime in or send me an email direct, now's the time for me to gather as much info as I can find.

Thanks everybody.

there's an ax-15 swap thread linked in the faq's. it's almost all off the shelf parts for a 93.(except the pedals, which are super hard to come by)

stroke the 4.0 to 4.7, if you're gonna be putting in for head, block, and piston work you may as well take the next logical step and throw a 4.2 crank and rods at it.

rear discs are easy and i'd personally just say get a 96-98 d44a from behind a v8 grand.

Would the d44a swap require a new drive line or ring and pinion?

Sounds like you've been here, with the 4.2 crank and rods do you have a cam recommendation? Is there a reliable online source for the crank and rods?

Thanks

Ron
