Over the time ive had my bluebird every now and then it tend to have the issue where, as im going to call it, it breaks down and doesnt make any power.
The engine is a u13 SR20 running the stock T25 turbo, 3in exhaust, pod,manual t piece boost control and a front mount. No tune to my knowledge and is stock other than what is mentioned.
Every now and then it breaks down and makes no power usually in cold air with the coolant temp running at normal temp. What happens is below 4k sometimes below 2.5k u accelerate, could be full throttle, 3/4 or even just partial throttle. It will pick up speed but not at the normal rate. Doesnt matter what psi the t piece is set at or even if the cars not running the manual controller at all it will still have the same issue. You can hear the turbo spooling and it will hit boost but it wont go revs pick up reaaalllly slowly till it gets to 4k, 3k or 5k rpm depending how bad it is then all the power will kick back in again and the car will start moving like most turbo SR do. Ill see if i can get a in car video to give an example of what its like to help diagnose the issue.
My initially thought was coz it had a boost leak but ive re done all the gaskets and fixed that and it will still do it. So im not sure if i need a tune or whats going on.
Recently slapped new plugs and leads on some irridium plug gapped at .03in.
Any help or ideas would be much appreciated. I got the old plugs if they are required for photo incase that might tell something.
Cheers
