1987 Supra 1jzgte Swap with R154.
It has been cold for the past few days here in colorado but 22 degrees yesterday and 7 degrees today. I just got the car and wanted to show a buddy a little of the power My 1jzgte has. Well for the past 2 days it has been a little choppy at high RPm but it ran fine about 3 days ago when it was around 45 to 55 degrees. I did here a small pop from the passenger side of the engine (sounded like the turbo's) but i was not under a real boost when it happened and it wasnt to loud but it was detectable. Do you guy's think i have a boost leak, bad spark plugs or should i kind of plan on it missing a little with the temp being as low as it is??
Any help i have only had the car for about a week
