Seen several TJs fixed up like this.

Not JKs in the area yet.

Really neat I think, especially on a older one.

How does it manage the jk with 105hp? Is it sluggish like our 3.8?

It's 105hp at something like 1800 or 2000 rpms, not redline like the 3.8l

Which equates to a lot more usable hp and torque at low rpms
