So I just got off the phone with the big guy himself Justin, and here's what he suggested.
For a turboed idi, if no head studs, 80cc pump and stock injectors.
If I get the head studs done, I can go up to a 90cc pump, stage 1 injectors, and wire the waste gate shut.
He did also say, while the heads are off, absolutely do the comp springs. He did say there is absolutely no truth to requiring an upgraded cam with the comp springs, and as long as the rollers are in good shape they can be reused too. He didn't mention anything about the rockers.
He also threw in, just in case someone comes across this in the future, head studs more than double the reliability and lifespan of the engines.
Guess I need to finish cleaning my garage up so I can get started on this soon. I definitely am not looking forward to the work.
Edit;
Just did the math, just in parts looks like I'd be about $2780 for charge air cooler kit, 90cc pump, stage 1 injectors, and the modified head gaskets. Guess I better start ordering things.
I think I'm just going to ship my heads to Justin to check out and do the springs. While I can do it, I am very rusty on checking out guides and lapping valves, I'll leave it to the pros. No idea what his head work costs.
