Yeah, I am going to focus most of my time in the intake. Ports need to be enlarged, and it wont be hard as the intake is aluminum. Yay! The biggest issue I see with it, is the EGR crossover is under it. I am tempted to plug the intake crossover, but the car runs so poor cold Im also temped to hook up a switch to the vacuume line on the passenger side manifold flapper to heat the intake up a bit on those cold starts. The car runs fine when the motors hot, but on those 38 degree mornings it stumbles when its cold, runs fine when you let it warm up though. Another reason I want to plug the EGR crossover besides the heat is that it hurts spool up. Have to pressureize all that exhaust gas under the intake along with the all the exhaust in the manifolds and the crossover. Its like having big tube manifolds when you are trying to spool the turbo, but dont give any mid to upper range HP increase.
So its walking that fine line, making it faster, or making it more streatable. I think streatable wins this time.
My other stupid Idea was take the stock CT intake, cut the bottom out of it, put in a small liquid intercooler inside the intake like most of the new blown ZR1 vettes and the edelbrock superchargers have and have a hidden intercooler. Big problem with that is the fuel would want to stick to the fins being they are cool, so unless you were going WOT all the time, youd have horrible fuel drop. Would work on a 84/85 car though!
The intake ports on the heads match up decent with the heads, but the intake ports are just puny compared to the gasket. Its like Buick never revised the 78 intake with the low port heads, and just made the 80 intake as a copy but out of aluminum. Anybody have the port size on a 81-83 intake?
Aren't TBs a blast to drive in cold winter weather...It's like they have a ball transplant or something
