I have a bone stock 87 Turbo-T.I have done a couple of things to help the car breath alittle better.Hooker exhaust,stock location [email protected] filter. Would it be feasible to port the stock turbo,mildly port the heads and port match the intake dunno
You can port the turbo, especially the elbow, but a downpipe will help air flow and a good cold air intake like the Big Mouth. I forgot where I got mine, but it's good. I don't think it's worth it to take the heads off for a mild clean up job on the heads, it's all pressurized anyways, and I think the only real gains would be gained by a huge motor with a lot a boost. Bolt some more crap on.
If you are bone stock then that means stock chip and wastegate. Little speed tricks will not help as much as a few pounds of boost. Get an adjustable wastegate (or convert yours) and a performance street chip from one of the chips makers you see floating around here. I wouldn't worry about port matching until you blow your first head gasket. Also buy a scantool.
