Hi all,
Just sorted engine and its all back in sound. Using a sti version 3 standard turbo currently, and was wondering how much boost they can handle. Its currently running 17psi on a zero performance set up.
Dont want to break turbo as engine build emptied my bank account

 

big boy when did it go pop ??

 

That should be a VF23 and iirc that should be okay with a 1.3 bar limit. In new money that's just short of 19 psi.
They have been run at around 20 psi constant without problems. Infact one madman on here was running one at a peak of 27 psi and holding 20 psi!!

 

Cheers fella.
