Ok guys I need some help here, this seems to be a common problem but no one seems to have the answer.my sr20det sort of bogs down after it reaches operating temperature.it feels very sluggish until it reaches high rpms.Even when it reaches boost it still feels sluggish until it reaches high rpm.I was told by the guys at enjuku that its a common problem and that it could be the crank angle sensor.what do you guys think?

I was gonna say check your timing. when it is warm if you can and check your battery to see if your getting good volts

My timing is perfect and the battery voltage is 12.5 off and running its 14.3 volts.Ichanged the hose that goes from the walboro fuel pump to the line that goes to the engine.it was all squshy and had one hole in the hose it probably expanded or let out fuel.now it runs a whole lot better tho.

I can't answer that question I'm broke I cant afford a fuel pressure tester lol .I just went straight to the pump because I've had similar issues with those good ol chevrolet 1500 they bog down in a similar manner.and as far as the correct fuel pressures I dont know what its supposed to be.I've read that its supposed to be 35 psi igniton on.and 45 psi with the engine running. I don't know how true this is.

wow i havent been on here for a long a** time.And i figured out what the problem was.The issues were only present when the engine was up to operating temperature,and down here in florida it gets hot as hell so that doesn help to keep the engine any cooler.Anyways it was the mass airflow sensors heated circuit wasnt actually heating up to normal temperature and the resistance was way to low on it.
