Here's the scenario.I just bought an 05 CTD and I'm getting piston rings done right now and was wondering, while the head is off, what sort of things should i get done while its there to make the truck reliable up to about 500 hp? i have, afe stage 2 intake, 4 inch turbo back straight pipe, edge juice with attitude and would like to keep the stock turbo. Any advice/ parts lists would be greatly appreciated. Also, i use the truck as a daily driver and would like to make it last for quite a few years to come and also be able to shock a few people around town.
