Hey guys,

New to the turbo world and I just had a few questions about increasing the psi on my sunbird. I have a 1.8t with the factory t2 turbo and i was wondering how much i can increase the boost on this engine without killing it. I have read on the forums that the pistons are not forged and that nobody seems to like the 1.8t. I am looking to reach the 210 to 230 horsepower range with my engine. I just brought the intercooler, bov (HKS) and a manual boost controller. I already have a equis boost gauge installed because i read that the factory gauge was not accurate. Also do i need to change any injectors, fuel pump, or any other fuel parts to raise my boost to around 10-12psi. I have read the boost faqs and trying searching, but i am on getting stuff for the newer engines and a few posts on the 2.0t being the fastest j-body stock car. Any help on this would be great.

yes you should change the injectors, im not positive, but ive heard that when everyone runs more than 5psi they always change injectors coil packs etc.
