ok guys. we all know what the 5sfte can do, equipped with a ct-based turbo, and moderate (10-~15psi) boost (180-~235whp)(i call it moderate boost, its all a "relitive" term..lol)
we know what shannons car made, @ ~11psi (~240whp) with the "ebay special" mismatched 50 trim T3/4 but, im interested in your thoughts on somthing a bit more reliable..lol so lets start with a few turbos that we can easily adapt to our cars. (using the generic ebay adapter, or the ATS, or whatever adapter you can get your hands on..lol) ok so, most of the adapters out there are T3 footprint, and by looking at what the mr2 guys are doing, anything sub 300whp is pretty much owned by the GT28rs aka the disco potato. jgreening on this forum had the very first Speedsource 'rs kit, and made great power with it, along with super fast spool and response. just going by that, it would seem like that it would be just as good a performer on the 5s, but, i have read curcumstances of 3rd gen guys having boost creep problems with it, which for us, would be death. its an expensive turbo, @ ~1100, but it is true ball bearing, available in both a t25 and a t3 footprint, with other housing options as well. for 270whp and above, we can start looking, again going by what the 3s guys use, (i mean hey, why not keep it simple, and go with things that are proven to start with...lol) we could go with somthing like what the ko racing "streetbrawler" kit uses, the T3/4 46 trim, with the .63 a/r turbine. IMO i think we could spool this turbo by ~35-3800rpm, and even at low (8-10psi) boost, still make great power, and be 300whp+ capable with proper engine management, fuel ect. i know alot of you guys would never think of droping 2k on half a turbo kit, but, in reality, for instance, somthing like the speedsource gt-28rs kit, which NONE of us could fabricate in our home garage,(carl does AMAZING work) that would "in theory" bolt on (other than all the other turbo stuff you would normally need), kinda makes me think otherwise about it. i mean hell, even fabricating one up, out of one of those crappy ebay adapters could be made to work, just a matter of buying the proper parts, and welding up the DP ect. what are your guys thoughts on this stuff??? -------------------- Former Team 5SFTE pro member ;)

QUOTE(supershannon77 @ Feb 7, 2008 - 6:55 PM) [snapback]639155[/snapback] is someone getting a new turbo? haha, not anytime in the near future. QUOTE(lagos @ Feb 7, 2008 - 6:58 PM) [snapback]639158[/snapback] It depends on what you want out of the car. Quick spool, or peak power. I really like the GT28rs and even the GT2871. The 2871 especially has a lot of potential for both impressive peak and quick spool, but I think those are better suited for a 3sgte then a 5sfTe. The stock 5sfe ecu seems to run a lot of timing advance in the 4k rpm range. At that point the 28rs would be making full boost ontop of advanced timing, while the 46 trim t3/t4 would be just starting to spool. By going with the t3/t4 you would get quicker spool up then you would with a 3s, and most of your power would be made up top where there is less timing and less chance for detonation. This would make for a safer setup, better traction and better 1/4 mile times. thanks art, but to be honest, i was looking more for some of the other guys to chime in, you and i have beat this horse to death quite a few times over AIM..lol -------------------- Former Team 5SFTE pro member ;)
