Justin, thanks for the info about the EGT's. I agree with Cole that gas turbos don't seem to see this as diesels do. Perhaps with the slower combustion of diesel as some of the fuel continues to burn past the exhaust valve as it is pushed down to the turbo. However, with the 5cyl issue with cracking manifolds, the EGT's are still important. The way to find out is to do it. I'll be adding a vacuum/boost, EGT, and fuel mixture gauges. I have oil temp, oil pressure, and coolant temp gauges too but that may make it look too much like a cockpit?
