I had a cheap cold air intake, and full exhaust on my last truck, and it ran faily strong for what it was. For any performance parts check out http://lcengineering.com/ I can also measure my 22re and transmission I have sitting around. I will let you know measurements tomorrow or saturday.
Brian, the car looks amazing, and glad to see you are back on here. My Transmission will be here next week, then I am gonna order all my rear end parts. Then I will be contacting you for an install and a tune.
If you could find the plans for one, I would be more then happy to make it for you for a cheap price. Im a very qualified welder, and I can get you the metal for cheap.
