1993 240sx: A lot of help needed

[sd2nola]

1. I swaped motors with an sr20det red top...With the MAF sensor plugged in, the car wants to kill unless i rev it. It will only rev to about 3500 rpm. Unplugged the motor will stay at an idel but not rev too well.

2. How-to time the motor.

3. On the valve cover there is a "T" fitting for (i think) oil returns or breather. the hose going to the back of the motor is hooked up but where does the front hose go to.

Thank for your help!

replace the mafs, if that doesn't work, then check the wiring.

timing is done on the black loop at the back of the coilpack harness. put an inductive type timing light on that loop and point it down to the crank pulley. you'll see the 5 or 6 marks on the crank and a pointer coming off the front cover. turn the cas to make the car go to the timing you want it to.

that hose runs to the rubber hose that's attached to the mafs to the turbo.
