Installed Turbo Technologies 60-1 kit last fall. In the process of rebuilding the engine, (forged blower/turbo pistons, heads ported, valves, springs, 1.6rr, 305 cam...). Already has 52mm throttle body. Question is, before I put the intake back on should I port/polish the runners or is it not worth the effort?
Let me know.
Thanks

 

It doesn't hurt. I've always put headwork at the top of things to do w/ a blower motor, regardless of turbo/super.
