I understand about the ECU's now, also regarding the fuelling issues at higher powers (the need to up the octane rating) and the need to change the ECU to a manual version I think it would be better for me to use my aftermarket Go-tech Pro-X ecu and cook a loom up using the plugs etc... from the aristo engine loom.
I know this might not sound the easiest solution if it were a 2JZ in a supra but remember this is going into a totally foreign car where nothing is going to be directly compatible, plus the Go-tech gives me tons of options and its totally future proof for upgrades. I am getting pretty good at mapping too
I have actually just returned from going to see the car itself, I have known the owner for years and drove the car itself about 4 years ago so I knew what to expect.
It hadn't been turned over in 3 months, with a quick jump start it started and idled as if it was new!!! The only thing wrong I could find was the valve stem oil seals are leaking oil when the engine is cold so you get blue smoke on startup, I have heard this is a fairly common problem with these engines. Would new seals from Toyota cure the issue??
