When I had my ECM reprogrammed he changed two outputs to control the fans at diff temps. I don't think the ECM comes standard with an electric fan control because most 4.3 used a regular fan.

yea, my computer and harness was redone as well. one output was for a fan. are you running electric fan solely? what tstat are you running? i have a 160* and a standard mechanical fan. want to go to a 180* and electric, the low coolant temp code keeps popping up. i didnt have a cooling issue, just like engines running cool. thats the marine tech in me. also what radiator? mines a stock 4.0. just looking for more info... thanx again.

Yes I'm running electric fans solely a high and low. I'm running the stock thermostat I think its a 180 but not 100% sure. The radiator I have is a 4 core I had made by BTR radiator its was for a CJ7 but fits very nicely.

Well I found one draw back to this swap I did!! Way to much horsepower and torque I keep braking u-joints on the front D30. . But it's a lot of fun 8-).

Just got mine on the road a few weeks ago. Other then a pesky oil leak from the oil filter adapter (added an oil cooler) and a faulty fan controller, its fricken awesome! Wiring was a bit of an issue since I had to fire the guy I hired to finish it up. Wiring is not my forte.

One time saving thing I did was get a GPS adapter to the electronic Autometer speedo. http://www.autometer.com/cat_accesso...l.aspx?vid=234

The Astro van headers and exhaust turned out really nice with the ceramic coating. I'll have to update my thread with some pics.

Next on the list is skid plates and mounting the track bar. I can only get to about 90km/h (55m/h) before death wobble, so track bar is a must.

Update here... Found a shallow pan off a 2wd S-10 at the wreckers. The key is 2wd, all the 4wd S-10s had the deep ones. Had to modify the pickup a bit, but it works.

I didn't know they made a shallow pan but i don't have a problem with it in my build. Here's a few updated pics. I got a D44 in her now with Hydro assist.

Very nice! I haven't wheeled hard enough to break anything yet, but I definitely know my D30 is the weak point in my build. With all the work I've put into it, I'd probably go with chromoly shafts and u joints rather then a new diff.

Hows the mileage? My first tank of gas sucked. Hoping it gets better as the motor breaks in.
