Yeah, youre going top need to have some machining done. At most you'll have enough room in the comp housing to go up 1 wheel size (and that's assuming the same backing plate diameter)

If you go w/the v or h-trim wheel you will only need to have the compressor housing machined. The 60-1 wheel would require machining of the housing and the backing plate.

Also keep in mind that the stock afm only reads up to 45 lbs/min so it would be difficult to tune for the additional "benifits" of the 60-1 (57 lbs/min) w/ an rtek anyway. The h-trim (48 lbs/min) is a better fit from that perspective.

I was running an H-trim hybrid and my turbine wheel let go and also ruined my compressor wheel. Then I switched to a 60-1 wheel and rebuilt it. The compressor housing and the backing plate had to be machined. The new compressor wheel was also too tall and had to be machined down. I really didn't notice a big difference in performance. Seems to pull a bit more on the top end. Power seems to be a bit smoother with the 60-1. It's hard to tell also because I switched from an s4 turbo and manifold to an s5. I'm running 18lbs boost dropping to 15lbs at redline.

When do you see 17psi? Did you replace the stock turbine wheel or upgrade it to a p-trim wheel? Any idea on power output?

Mine is my own rendition of a BNR Stage 1/2.

It has the full T04B compressor housing like the stage2 but is only using the stage1 compessor wheel. I have the internal wastegates blocked off by welded metal plate and no backcut and the standard series 5 turbine wheel and housing.

I will post up some data logs later.

If you welded the internal wg shut how is your setup routed?

It is an aftermarket manifold made from thick wall mild steel steam pipe.
