XDR 4.0 can reuse mounts with bolt in mounts or weld in. 2.5 require weld in mounts. I did my swap into a 2.5 since the cost difference between the two couldn't make up the price point.

I did find a few other NOVAK websites -

Www.novakautoparts.com
Www.novak-adapt.com

Were you referring to one of these?

Yea Novak Jeep Conversions - Home sorry about that

JeepersDave The location of the radiator is the same between the 2.5 and 4.0. The real difference is the motor mounts which are about 5 1/2" farther forward on the 4.0. In the case of a V8 swap it doesn't matter since the mounts have to come out anyway

Evpjr The Engine compartment in the 4.0L and the 2.5L are the same, but the location of the radiator, maybe set a little further back so as to accommodate the shorter engine block and allowing the fan to bring more air flow through it.

Physical Differences Between TJ Engine Compartments

If I wanted to drop a V8 (& auto tranny) into a 1997-1999 TJ, should there be a preference as to whether the TJ was originally a 2.5L or a 4.0L?

Is there a difference in the engine compartment, or with the firewall? Or are they pretty much identical, when it comes to the areas under the hood and body?
