Here is the scenario, just installed a cast manifold turbo kit with a used PTE67 from KTrends on the board. Also just had the trans built by BL. Got the car up and running today and it won't build any boost at all. Also makes a weird sound at about 4k rpms, sounds like a scraping or rubbing of metal. I am still running MAF and everything is installed correctly, to my knowledge. Just won' build boost at all and makes the weird noise. The wastegate isnt opening either. Turbo will spin freely with the car off. I'm lost. Please give me any advice!!!
