The engine in my 2001 TJ is knocking. I was considering buying a wrecked XJ for the 4.0 engine. But Id also like to have HP30 out of it and the AW4 tranny.

Anyone know of a reason that couldn't use the 4.0L out of an XJ? Or any particular years I need to look for?

For the HP30, I need a 92-98 model.
Not sure on the engine or tranny, but I'm reading up on it...

I am considering using a 5.3 LS style engine with a 4L60E tranny. I'm pretty familiar with the GM drive train. Do you have a write up on your 5.9?

You sure? The top end is the same, but the blocks are different. TJs had two different blocks, 97-99/00-06, XJs used the same block 96-01, but used two different heads, 96-99/00-01.

It would work, but it's not a bolt in ordeal. WJ engine swap would be more direct.

thx... that's what I was looking for. I was hoping I could use the same short block. GM has spoiled me with the V8 stuff all being interchangeable. My 4.0L engine sounds like a diesel its knocking so loud.

As much as I'd love to do a V8 swap, time is a big factor. I was looking for a quick fix for the 4.0L engine and then have the option of using the HP30 and AW4 later on. But I don't think it's going to be that easy.

I'll keep digging, but it's looking like I need to scrap that idea.

That's not out of the picture... I may do that.
