Drag Gen 3 turbos or F-Max turbos are the best complete kits that I've seen. They come with everything, BOV, wastegate, all piping, even intercooler! That is why they cost like $3000. All you would need after that is a boost controller. But for internals, go to www.theoldone.com
and they have pistons and rods plus that guy really knows what is good for honda motors!
