I had a run in with an older type of jetta. It looked totally stock. But it was really fast. We didnt actually race but we both took off rolling in 1st gear. We were neck and neck. I dont know much about the cars , but he said he had a Vr6 running 10 pounds of boost. Props to that guy for a bad ass sleeper. Ive got alot of work done including RA gears, cltuch flywheel, vf -34, intercooler, open exhaust...ect.
