Stock turbos have 84k on them. Starting to expect death whine anytime. I have a back up set of stockers ready to go, but am not sure I will use them. I have read the new turbo guide. I know the T04 and SP63 are the most popular small singles. What are usual prices on these kits new and used? I would want to keep almost everything else stock, until I had the money to slowly upgrade other parts. I would want small trim, like .58. Stock fuel, MAF, IC, ECU. Is it possible to keep all these parts stock? 1000 for vpc, 1200 FMIC, those things really add up. Can you even keep the MAF after going single? I would be happy with any where from 400 to 450 rwhp, I'm not greedy. Also, how much to install usually. I have a guy that I know pretty well who would probly not rape me on install price, but still, ballpark? Just starting to get some plans together here.
