Or, spend less money on a 5.9 create motor with 325 or more HP.

Ya I don't know how a $10,000 crate motor is going to be cheaper than a stroker kit.

I'm planning on getting more torque from the 5.2 now that it's open 'cause it got sand inside ... so if it's going to be on 0.20 why not gettin it up to a 5.9 with the master kit.

the 5.2 has already d44 in rear, but i know that the 5.9 came with a stronger transfer case.

Im pretty sure the transfer case is the same only the trans is stronger. 46re in 5.9
44re in 5.2

What is needed for a 5.2 -> 5.9 swap?

93-95 ZJ V8
5.9 flexplate
5.9 harmonic balancer
5.9 driver's side motor mount
torque converter from 96-98 V8

96-98 ZJ V8
5.9 flexplate
5.9 harmonic balancer
5.9 driver's side motor mount

Notes
You can use a spacer or washers and make the 5.2 motor mount work.

You can oval out one of the holes on the 5.9 flexplate and make a 93-95 torque converter work.

Late '95 ZJs may not need the torque converter because some of them came with '96 flexplate and torque converter.

A complete motor from a 98 5.9 ZJ will bolt right into a 96-98 V8 ZJ. Because of OBD1 and EGR, it will not bolt into a 93-95 ZJ. You will need to use the old throttle body and sensors. If you have emissions testing, you will need to use the old intake manifold and the passenger's side exhaust manifold to maintain the EGR system.

The upside to swapping a 5.9 into a 93-95 V8 ZJ is the 46RH transmission, which is stronger than the 44RE used in the 96-98s.

Technically the 249 and the d44a in the 98 5.9 were better/stronger, not that I've seen a difference. The trans in the 5.9 is a different model than the others.

The vehicle it's a 1997 Grand Cheroke limited made in Venezuela, so it came with d44 in the rear.

you would need to bore the cylinders .090" over and throw in a 5.9 crank(which are external balance by the way) the absolute maximum you can bore one of these over is .060, so you can't get it to a true 360 cubes.

if you're going to stroke it you should just go with a 390 kit.
