Feed Back
I have used the red FJ40 now for several months. working on and refining issues and bugs. I wanted to give some feedback on the build and specifically some of the parts used.
1. Corbeau seats are awesome, fit like a glove and very comfortable.
2. 4x4 Labs, Luke's, steering setup is tight, no slop, no stabilizer is needed. At 70 MPH on the interstate you can hold one finger on the steering wheel. This setup is for spring under and he also has a spring over setup. The Saginaw steering head is responsive and takes a little getting used to as compared to the mini-truck power steering on the '75 FJ40. But overall, I love it. Very nice setup. Drives like a modern vehicle.
3. The TPI 350. I am not sure you could ask for a better engine. more than enough power and torque. In 2WD high range I idled around on the dirt roads at my hunting club without my foot on the gas pedal and the truck climbed hills, without lugging. The ECU controls the IAC (idle air control) flawlessly to try and maintain the idle rpm. Therefore, a great creeper at idle.
At 70 MPH the rpm is approximately 2550 to 2600. it will run 70 all day long with lots of pedal left. But, who needs more speed in a 40!
4. Cooling- aluminum 4 row radiator, Taurus 2 speed fan. Hypertech fan switch with 176 on, for low speed, with temp sensor on the side of the head. The high speed is controlled by the ECU at 220 on or the AC on. I did put a manual over ride switch for the high speed to control the fan if needed. I mounted the stock LC 2F temp sensor in the top of the water pump, which feeds the stock temp gauge. I also have a temp sensor mounted on the right head at the rear which feeds the 3 pod gauge set mounted under the radio slot. Therefore, I get two reading on the engine temp. The stock gauge barely gets above the first mark on the stock gauge at normal operations. When I first start it up, I see the needle going up almost to the second mark on the stock gauge and then the thermostat, 180 degree, opens and it drops back to the first mark. Under 65 mph the head temp gauge reads 190. with the AC on, outside temp above 70, and cruising at 65 mph (2450 rpm) the head temp may get above 200 or 210 but still in the green on the gauge. pushing it to 70 mph the head temp gets to 220 and the stock gauge (sensor mounted in water pump) gets close to the 2nd mark on the stock gauge. Therefore, I am satisfied with the engine temps and actually with the cold weather like it is the heating unit actually does not blow warm enough in my opinion.
5. transmission and transfer case. I wish it were lower geared in first. The Mark's adaptor works great, a little noise out of the throw out bearing. I did not rebuild the transmission or transfer case with the idea that one day I would install an H55 and split case. I've read all the right ups on the install of an H55 and would love to see some feedback from anyone who has done it and has used the H55. is it worth the expense and effort?
That is all I have right now. I just wanted to give some feed back. I read a lot of install and how to threads but seldom do you see feedback after the build and actually the item being used. Something may look cool, sound good and all glitzy from the first look. However, the actual real life performance is really crappy.
I hope this helps someone.
