[QUOTE="powerlifter405, post: 1485573, member: 2044"] IIRC anything much more in CFM than the GTP38R valve springs are suggested. The consensus is tuning is a huge factor. There are plenty of guys w/ big turbos and injectors in the 300cc-ish range that tow. Best bang for the buck simplicity from what I gather is good tunes, factory single shots and GTP38R. Singles give a decent bump in hp/torque, the GTP38R is bolt on, add tuning and you're done. It's all about how much you are willing to spend and how much time you are willing to invest to get what you want. And I want to say anything smaller than the 250s should be doable on the factory HPOP. This a ball park figure from Swamps for a reliable set up and for ease of install he suggested the GTP38R. Fwiw, KC is now offering BB setups so something for the 7.3 might be viable. I had the 38R on my 02 6spd and found it was more responsive compared to the factory journal setup. 200/200's max out @ 550rwhp 238/200's max out @ 600rwhp 250/200's max out @ 675rwhp 300/200's max out @ 725rwhp At the end of the day how much money and how much time? Only you can answer that. Once you do, call Swamps or Warren for quotes. Good luck [/QUOTE]
