Hey all I am new to this forum and looking for some advice. I just bought a 03 tt 6spd Z with 82k miles. Pretty much stole the car from a dealer they had no idea what they had. The car has some serious mods like the greddy tt kit with turbosmart wastegates and bov, AP racing front and rear big brakes, and im almost certain it has a built block as I can see somewhat fresh silicone on the upper oil pan and the timing cover. I know that just means its been apart but I cant think of a reason why the engine in a tt car would have been completely apart without at least putting rods and pistons in. What should compression psi be like with a built low compression block? Also the car runs great and pulls hard. No boost gauge or a/f gauge and I cant find what it was tuned with... the factory ECU is bolted in the factory location and I took apart most of the plastic in the car looking for an emanage or haltech and found nothing. What could this car be tuned with...? EPROM? COBB? It also has factory exhaust merged with the tt kit this will be upgraded for sure. Not sure what size injectors... but I want to add a boost controller race gas and put it on the dyno and turn it up. But I want to make for **** sure the block is built before it gets turned up so the oil pan will be coming off and a compression test done. Any advice would be much appreciated!
