5SFTE larger turbo disscussion, lets talk turbos other than the ct-26 on the 5sfe Options

[presure2]

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???

I'm in the process of turboing my 5sfe Camry with a GT35R. From what I've heard, this turbo usually spools at about 4,500 rpms, which seems normal but the problem is maxing out that turbo "efficiently." I've been talking to my parts person for sometime now on getting some work done to the head and the stock cylinder head bench flow indicates that there is a big restriction on the motor coming from the exhaust side. From there results, it appeared that approximately 80% of the exhaust side was flowing as to what the intake was flowing. At that, this would mean an upgrade to Ferrea Valve stems, and definitely new cams, which Crower provides for our engines. Those seem to be the biggest factors on getting the power out of our motors. I plan on getting the AEM EMS this month along with a custom harness, but I have no clue as to the best way to run this with a btm. There's still a lot of things I need to look into to work out on my setup
