Hello everyone,
I would greatly appreciate options on this subject as to how one could go about
getting a 4.0 inline 6 to do almost as well or better in hp and torque wise with some
high performance parts. I see this as the most practical course because,
i have put too much money into my 4.0 to let it go easily.
And i like the 4.0 build quality.
I have a 93 Grand Cherokee. Any suggestions anyone??

Thanks everyone and,
Merry Christmas.

 

The only thing I can think of is to throw on a blower but you would still not have that v8 sound. You'd probably manage to match it on fuel consumption though.
