Hi all,
My sr20det seems to shudder once it hits around 7-8psi, and from them on (to around 15psi max) it feels as if the brake is on a little. It certainly doesnt accelerate as much as it should even though the boost guage still says up to 15psi.
It has been happening since i removed and re-installed the stock turbo.
I checked the intercooler piping 3 times already, first time replaced one clamp which was threaded, second time replaced another one that was suspect, 3rd time replaced the other 2. After each time it felt normal until i boost it around 5-6 times, then starts shuddering again. I thought i must have done something wrong when i put the turbo back on...
It used to shudder and feel flat after 11psi, now does it all at 7psi. I thought there might a leak somewhere else in the plumbing and hit it around the block a few times to see exactly when the problem starts and after a while the exhaust temp light turned on..
Pulled into the driveway and low and behold its red hot just after the cat. After this im thinking it could be lack of fuel, or blockage somewhere. Tomorrow i will reset ecu, clean afm, replace fuel filter, and maybe spark plugs. I will also remove the intercooler and maybe put the stock one back on.
A friend in a skyline has said he has had similar things happen to his car but goes away after a while.
I dont think its fuel (unless i have had bad luck lately). I use optimax all the time, and i just filled it (still had the problem on the old tank). I also filled it at the space station at lane cove which goes through alot of fuel.
Anyone else had a similar problem or that could give me some pointers as to where i should look?
Any help is greatly appreciated...
