T5 reliability? 2.5L bellhousing?
Our '92 YJ has 85K on it now and the weak stock drivetrain is showing it's age. It's a 2.5L 4 cylinder with an AX5 and NP231. The rear bearing on the AX5 mainshaft failed at 75K. The Dana 30 front-end just broke a shift fork on the axle disconnect. It's time to think about upgrading.
I want to keep the 2.5L. I want to get rid of the Dana 35 rear, disconnect Dana 30 front, and the AX5. I'd also like to have a gear drive transfer case.
I'm looking at going spring-over with a Scout Dana 44 rear and Scout Dana 30 front. I'll probably stick with 4.10 gears and run 33x9.5 tires (currently running 30x9.50). I'm hoping to gain make up for the taller tires with a lower first gear. Ideally, I'll run a Jeep Dana 300 transfer case. I'm undecided on the tranny. I'd prefer a 5-speed, don't want to buy costly adapters, don't want to spend the money for an NV4500 (nor do I need the strength), so I'm considering the T5 but I don't know much about it yet. Are there any major reliability issues with the T5? Keep in mind it's only going behind the 2.5.
Does the YJ 2.5 have the same bellhousing bolt pattern as the AMC 4-cylinder in the late CJ7s? Is that the same bolt pattern as the 6-cylinder in the CJ7s. I know the CJ7 bellhousing will use a different clutch setup and won't have the mount for the crank position sensor, but I can deal with those things.
Thanks for any help,
