Thanks for your input. I suspected as much, because while the power did increase it was very little. If I had time, I would have replaced the entire trap oxidizer with tubing similar in diameter to the turbo and exhaust. But, this is my daily driver and it was a weekend project and I didn't have access to the proper material. I have been researching the possibility of exchanging the intake, exhaust and turbo with Federal parts, but after doing some research on your links, it sounds like I need to try and locate a VNT and fit it to the car. By the way, very interesting work you have done on your 240. I would ultimately like to integrate a 5 speed into my 300, tighten the suspension and tweek the fuel and turbo system for increased power. I would be interested in any further information you could offer. Feel free to email me at:
