Just finished my install of a stage 1 universal kit and I love it !!!! I did weld up a custom mount that is part of my battery hold down and coolant reservoir. All of it fits into the stock battery location perfectly. I end up buying a new Toyota windshield washer tank due to a leak from a old WI system that I had installed previously. Fitted the bulkhead and float and reinstalled in the stock location. I did add a low meth/water warning buzzer to the float switch. Tapped and installed the
pressure switch directly where the EGR valve was located on the back of the intake manifold. Easy to view the onset setting and adjust with no hoses to worry about. I also moved ( welded a new bung) the IAT sensor (HKS VPC) from the manifold and relocated it to the exit of the FMIC. This not only solved the heat soak problems the probe had @ the manifold location, but it also put it up stream from the Meth/water to give a more accurate reading ( it won't get wet/colder and want to dump in more fuel).
The Kits Fit, Finish, Tech support, and Customer service were AWESOME!!! Thanks DevilsOwn.
