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've got a few questions

1: will water cooling be necessary for a turbo other than CT26 as long as a turbo timer is used? I know it would be better, but I don't really understand how you get coolant to this turbo, you have to use some kind of banjo bolt kit?

2: wastegates, if I cheap out and get an ebay one with an 8 PSI spring, even though I really want to run 10-11 PSI, will it be ok? I choose the lower spring to give some head room in case it creeps, and I know it will. would replacing the spring in a cheap wastegate with a geniune Tial spring make it better?

3: is a 46 trim t3/t4 with the 0.63 A/R turbine gonna be the best size for the 5sfte? I want something that will support 300 WHP, but not much more because I don't want TOO much lag. if the turbo doesn't make full boost until 4K, then you've only got about 1K rpm of actual power before it starts pinging and becomes super slow and is bad for the engine. I plan to get water methanol injection, and then down the road an emanage ultimate. But, even with the CT26 I have on now, I was planning not to take it past 5200 RPM until I got water/methanol, since it had no power that high anyway I didn't see the need to go higher than that. plus I REALLY don't want to blow the engine.

4: should a restrictor still be run with this turbo?

I'll probably start ordering parts once these questions are answered. I've decided that my wheels aren't coming for another few weeks, and I don't need to get them immidiately after they come in, so turbo goes in now, wheels come later.

#1 yes, if it is watercooled. on most of them you choose either a oil cooled, or water and oil.
#2 DO NOT cheap out on a wastegate.
think about it, if that decides to take a crap on you, what happens when you step on the pedal? unlimited boost. that would bad. or, it could just start leaking, not opening correctly ect..all still bad IMO.
buy a REAL WG.
#3 do your homework, and figure it out.
there are figures in the sticky that allow you to plot your airflow need accross a compressor map, use it.
#4 yes. the T series restrictor you should be using with your ct-26 is made for "T" series turbos.
