It's out of a late 90's Volvo wagon. The unique part is that the fan has perimeter bolting to the shroud so it's a bit way easier to fab up some mounting. These Volvo fans also have a cool-guy relay for use of the high/low settings of the fan too.
878 miles logged already. It now has 5.38 gears in it too. I wish we could have went deeper with the gears but the JK D44 housing up front would not allow it unfortunately. Now I need to finish my short list. The funny part now that it's out in the world, it's showing up on the Internet with people taking pics of it. Lol
For on road performance, I'd go deeper. Remember that 6th gear is a .62 overdrive with a lot of tire/wheel mass. There's a 4:1 t-case so it will not need any more gear for that. The hydroboost will be nice to have when it's in low range trying to keep it pent up.
It's back now for an oil change and a fire extinguisher install with a quick release mount. While it was here, I replaced the torn rubber shifter boot with a leather piece. I made some escushions to slide over the shifter shafts to cover the safety wire.
I just met up with him this past weekend. He has logged just under 2500 miles so far. He said that this Jeep gets more looks than his cool-guy $700k Porsche. The only issue that we have had is the PWM fan controller decided not to play anymore so a replacement is needed.
