today, i was driving down the street, and i raced an old MR2 (i beat him to hell) i did a few pulls to test the car, and it was boosting around 10-11 psi, i did a few more pulls and it went to 15 psi, that was strange, since i dont have any boost controller, i kept driving until i met the mr2 guy, and i after i finished racing him, the car was feeling like it wasn´t getting any fuel, but fuel was ok (car dying if the pedal wasn´t pressed down). i drove it home, and now everytime i try to start the car, it goes through 2500-3000 rpm´s and it dies within 2 or 3 seconds. i popped my hood, and i saw that one of the ends of my wastegate line was off (thats why i overboosted i believe), so i connected it again, but the car keeps doing the same thing, i turn it on, it revs to 2500 and it dies within 1 or 2 seconds, i made sure everything was connected alright, Coils, Maf, etc. i don´t think i blew the engine since the oil is ok, the oil pressure is ok, the water seems fine, no overheating at all, and no smoke. the only way to have the car running is to keep the pedal down. any help is greatly appreciated. :thumb: Here are my mods:

Aftermarket boost gauge
2.5 downpipe and exhaust
16g turbo
stage 2 clutch
ported turbo
 
i was thinking probably of an electric problem... any thoughts? i roughly checked the intercooler piping, and they look alright to me. :(
 
i fixed it!!!! it was a vacumm line that apparently attaches to the valve cover towards the back of it.. thanks for all your assistance guys :thumb:

Cool, glad you got it worked out ;)
BTW, the vac lines that are behind the valve cover are the following: PCV valve, BOV line, FPR line, and Brake Booster (in that order) :thumb:
