I think Jeff Daniels did the 4bt swap for them...

I saw it at a show and apparently it can be street legal here in PA if you retitle your vehicle as a specialty vehicle or rebuilt vehicle or something like that. There was a guy with a TJ thats street legal here in PA running the 4bt and he said on his worst day, he still gets 24 mpg.

sign me up.

To bad the KIT alone is $10k! Then you need an engine and tranny.

I believe the kit is $9500, not including the engine or tranny. $25-30k installed.

Was that with a used engine or a rebuilt crate engine? If its a crate engine that's a good price. I was quoted $25-30 by Jeff's Jeep Yard for a reman crate engine and a nv4500 tranny.
