For 600bhp the oem 2jz-ecu Mkiv Supra Turbo ecu would work just fine.

Will the engine ecu have any issues once I take away the auto box's ecu?? On the vauxhalls it's simply a case of earthing a pin on the engine ecu to tell it the gearbox is manual.
I'm glad to hear the factory ecu will be happy with 600bhp, if we ignore the obvious turbo, exhaust and intercooler upgrades what else would be required to achieve 600bhp? The engine already has a fuel cut defencer (hks).

For 600rwhp, you'll first need to decide what kind of fuel you want to run (pump gas alone won't work): - pump gas with a heavy shot of methanol? - race fuel (104+ motor octane) - E85? - any other ideas?

To make 600rwhp+, you'll need an aftermarket fuel controller (eg. an A'PEXI AFC Neo), and a small-medium single turbo kit (eg. 57+mm inducer). The oem twins can't make 600rwhp. Be sure you're running Toyota's 550cc injectors (your j-spec 2jz-gte probably came with 440s, so you'll have to swap them out). Together with the meth kit, you'll have enough fuel for 600rwhp, but just barely. For additional safety, I'd recommend an aftermarket fuel pressure regulator, and bump it up to about 50psi base.

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?? ![]()
