[QUOTE="blk350on20s, post: 894596, member: 1550"] I'm going to be getting turbos next week. I've been having a hell of a time with this decision and appreciate all the help and information I've received so far. My first thought was 66/88 billets until I received the email that I was in the voting for DPC. That made this decision a lot harder. I want a fast spooling setup and in Michigan spinning up 66 is no problem. But introduce altitude and there may be issues. I dunno as I've never been there so that's why I come to you. Thoughts now are 364.5 FMW. A 367.7 FMW was also brought up. Seem like great turbos and the 67.7 flows a lot of air. Question is how will it spool at altitude. I believe both turbine sides were 73 or 74 with a .91 housing. There is still the standard 366 cast as well. Would adding a billet wheel be beneficial? Now the Garretts. I like the idea of ball bearing but the cost gets up there. So far a gt4088, gt4094, and GTX4088r. I would love the GTX but at close to 3 grand I just don't think its doable for me. I don't know sizing with Garretts at all so any reccomendations or insight is great with that. I will be using a s488 billet as a low pressure and will be gating both turbos. I will have spray but I really don't want to rely on that. I'm shooting for 1K HP but realize at altitudes a new game and I'd rather have a well performing truck than a dyno monster. And if I don't get in or after the competition I can always size up as east coast air is awesome LOL. Sorry for the length but what you guys think? Oh a 362 FMW was also mentioned. Ryan [/QUOTE]
