please help! im going to the track tom. 1jz no boost at WOT!

[jdmvigor]

first i have a 93 sc300, with a 1jzgte. i check almost everything already. map sensor, ignitor, timing didnt jump and the tps.. the car can slowly rev up to boost. but it wont boost at WOT and it feels like fuel cut as soon as i WOT. any clues?!?! what happens if the cam or the crank sensor goes out.... can that be a problem?!

Try checking for codes first. Do you hear the turbo spooling but the car doesn't go anywhere? Check for boost leaks as well.

if it doesnt boost it sounds like a timing issue or a turbo issue. there are ways to check the sensors with a meter to see if they are still good~ i say triple check the timing and look at the turbos make sure the compressor is not broken off or soemthing
