I'm rebuilding my engine right now and plan to do some upgrades while I'm there. I'm looking for...
-Undented headers and y-pipe (can be separate and I plan to repaint them)
-58mm TB
-Lifters (mine got metal in them)
-Roller Rockers
-Injectors (not sure on # yet, but will update with this when I know)
-90 degree intake elbow from TB to MAF
I can't think of anything else now, but I'll add things if I think of more.
