Okay well looking at your list there are a few things you dont need. Forget the FMU and hte Emanage. You have hte apex vafc which will work better than both of those. Just add some dsm 450cc injectors like 50 bucks from www.thepartstrader.com or ebay. As for stock internals I wouldnt boost more than 8lbs. But if you want to boost more get the pistons and then get your rocker arms polished shotpeened and matched to the pistons. Then maybe new sleeves or ge tyour deck closed. Thats pretty much all ya need. But tuning is where its all at. The better tuning the more you can boost. Have you thought about keeping your comp the same or raising it for boost?? This way you wont have to lose some of your bottom end and you wont have to boost as much to get the same power. I would also get a new fuel pump too. A msd ingition with boost retarder would be nice too. Good luck man.
