I haven't posted here in a while. But I recently installed my 1jzgte in my supra and it's not going so well. What all is done I'm upswing a aristo 2jzgte ecu, with aristo 440 injectors, precision 6262 turbo, 40 mil waste gate.
I have ngk plugs gapped to 22. Now my prob. The car is not running worth a crap. It misses bad just on start up and won't idle till it warms up. I can give it pedal and the miss clears out until I try to drive it. Under a load like going up a hill it starts missing agin tell I press the clutch in and rev it up and clear it out. But it still wants to miss. I'm at a lose so any help would be great full.

Check for hairline cracks down the coils, its fairly common if you have the stock ones. Could be losing spark if it arcs up the cracks. On my engine I have my NGK plugs gapped to .27 so that could be something to test too. I used to miss a lot at idle and at crusing speed (1900-2300rpm) because of cracked coils.
