T4 Turbine wheels

[NoNaMeS]

I have a 60-1 Hi-fi T4 turbo, I am unsure of what size the turbine wheel is. I got it for cheap, and would use it if i can. The car rarely see's street time, and i have 2 motors for it as well. The motor/trans it would be on is capable of supporting high rpm's and a decent amount of boost. Now my question is, what size turbine wheels are you T4 guys using? What rpm do you see full boost? I don't need to know about the t3/t4s, Just the big toys. The exducer is about 2.5" and the inducer 2.75". I know the compressor side also plays a role, but I am not too concerned with that as of now. I'd like to keep a larger A/R on the hotside because it is a high rpm motor. So please anyone with input reply. I'm gonna try to get some pictures up.

I'm assuming this is the tubonetics 60 series turbo, The 60 series turbos have 3 different tubine wheel trims: O trim 2.296 / 2.920, P trim 2.542 / 2.920, Q trim 2.693 / 3.111. They have a bunch of A/R options depending if you have the divided inlet of open inlet on ex housing. Hope some of that helps.

Make sure it's the 60-1 you're talking about, not an acutal 60-trim.

It is most definately a 60-1 t4 in an on center housing, it came off of an rx7. I'm not even too worried about the turbine housing a/r, as I'm going to buy 1 that fits the bill for me, if this turbine wheel isnt too large to make some good power by 5500 rpm. I know it will shine at 9k, but if it spools at 8k it'd kinda defeat the purpose.

What exhaust wheels are the t4 guys running? I'd also imagine you are using .82 and up A/R on the housing. I know the 60-1 compressor wheel is on the rs60, any idea what turbine wheel is used? i know they are in dsm style housing's but what kind of a/r are they using? I'm trying to move away from the t3 and dsm style turbine housing's as i believe it to create too much manifold pressure for what im looking to do. Anyone with T4 turbine experience please chime in. There may be some info on this site regarding it, but i was unable to find it looking for t4, or t4 turbine, or t4 exhaust, or t4 housing. There is alot of info on the t3's and hybrids, but they really dont apply to t4's. I've also searched NABR, Dsmtalk, Tuners, even googled a bunch of times.
