Just wanted to post some pics of my ongoing 606 swap, this has been a tough one.
I'm very impressed with my mechanic's work on the 606 swap. I used factory 606 engine mounts to make the job easier, so only modification needed was trimming of the intake manifold. We had custom radiator/intercooler built, used an electric fan as space was pretty tight.
35" tires fit easier than I thought, we only had to trim the body mount behind the rear tires - looked like it would hit at full compression. Viking lift springs with bilstein shocks - didn't measure but around 3" lift. My mechanic built a custom drag link as the front axle was off center by about 1" after lift. We also made a custom drop pitman arm to help make the steering a little less scary.
The 606 with 400hp pump and HX35 is putting some serious power out! I've had a lot of trouble finding a clutch that will handle it. I tried the Larkspeed drivetorque stage 3 clutch from the UK that can be found on ebay and claims to fit a 711.116 transmission, but pressure plate was too large and bolt pattern didn't match flywheel - having a blast trying to get a refund. I ended up getting a new factory pressure plate and clutch. I even cryo treated the pressure plate and it's still wanting to drive through the clutch. I will be working on getting a clutch made for this but it's driveable for now.
Thanks for looking, any questions just ask. I'm not organized enough nor have the free time to post a full build thread with pics. I've built several vehicles and this has been by far the most difficult as far as finding parts, but totally worth it - this truck looks amazing and sounds insane. Hoping to make the 1,000s of 4 door wrangler drivers around here shit their pants!
Intriguing arrangement of the coolers. I see super thick double pass radiator above a rather small intercooler (300-400hp diesels are using intercoolers larger than that radiator). Do you have an EGT gauge?
Is there an oil cooler somewhere in there too?
What factory clutch/FW did you use? Factory for that iron box transmission?
That G definitely will make some of those Jeep folks wonder. Congratulations on getting to finally drive it!
Awesome looking G. Where are you located? 4 door wranglers are a dime a dozen in NC. And most only make it to the mall and you ask them about wheeling and they are like, I would never take this off road. Head shaker for sure.
