S5 hybrid turbo advice/questions
So I have a blown S5 turbo that I want to rebuild and throw into my S4. I was thinking about rebuilding it as an S5 hybrid. I have a t04b back plate and compressor housing and a t04b 60-1 wheel. Reading around off the forum is a bit difficult as the info isn't as consolidated in one place. What I could gather is a rebuild kit can be sourced from g-pop shop. I was more curious about what size turbine should/can I use with the stock turbine side? What would be the most efficient for street? I'd like to avoid having the hotside machined if that's at all possible. This is a street car looking for roughly 300hp. Am I going to have a problem with lag using this comp wheel? Apologies if these seem as typical noob questions but I'm relatively new to understanding properly sizing turbos in general.

The 60-1 wheel is a bit large for your power goals and would be better suited for a larger turbine wheel. you can achieve 300 whp on a to4b v trim easily retaining the stock turbine wheel and have better spool characteristics.
I actually have a v-trim compressor housing and wheel (actually the entire turbo) with a P-trim turbine wheel that I was considering using as a hybrid, but I would need to machine the comp housing for a 60-1, maybe we should trade, lol.

^RotaryRocket88 put together an awesome thread regarding rebuilding/hybrid turbo's.
Most hybrids keep the stock turbine or, at most, get it clipped.
BNR gives out a lot of good info on their hybrid turbo's as well.

Putting this stuff here for future reference for myself and possible others.
After talking to a few different members personally about their turbo setup's it sounds a lot like this 60-1/stock turbine is plausible. Some members have said they reach full boost around 3k rpm and others 4k rpm. All this depends on the timing of the internal wastegate and aftermarket wastegate actuator.
