tbo92 Posted July 11, 2009 Report Share Posted July 11, 2009 Hey all, have the KE55 off the road at the moment.. getting stripped and converted... my daily is now a GP Turbo, Corolla 2! perfect little car, 1.5 turbo sohc. BUT lol i know nothing about the car itself, stock boost? at the moment. when i accelerate it takes off, and boosts up but appears to stall for a split second. and then it takes off again, how ever seems to have much lower boost. say from 7psi to 3psi... turn the car off. start again and away it goes.. i have seen on some other images that there appears to be a BOOST switch on the dash.. could this be causing the issue? it appears to be a high / low boost switch standard! or could it be something else ??? vaccum sensors or what? Cheers all! Quote Link to comment Share on other sites More sharing options...
towe001 Posted July 13, 2009 Report Share Posted July 13, 2009 Wouldn't say no to one of them if i had the chance and had the money. But anyway, i'm no turbo expert but it could be a carbon build up. I'd say get a vacuum gauge on to it and see what the idle's like - might sound ok but.... And then see about a turbo gauge to see what the boost is like. But like i said - i'm no turbo expert Have you tried having a google for things like "Turbo Troubleshooting" ? Quote Link to comment Share on other sites More sharing options...

Thanks for the info... turns out after putting a boost gauge on it - the boost has been wound up to 15PSI! (idiot old man!) so it would seem to me that the map sensor is cutting out and bringing the boost back to a safe lvl.. i think if i wanted to keep that kinda boost i would needa 2 bar map sensor.. how ever i think i will remove the dodgy boost tee he has in there and run standard boost back in it.. should be A ok then! anyone agree?? lol Quote Link to comment Share on other sites More sharing options...
