HI, all. Looks like the forum is dead, but in case anyone can provide me some info, that would be great.

From all the research I could find here the VJ11 and T-bird VC32 share the same exhaust wheel dimensions, but the compressor wheel of the t-bird is larger by about 3mm (39mm vs 36mm for VJ11). I stumbled on a billet wheel that has the following measurements:

Nose Dia: 10.00 mm
Inducer Dia. : 40.00 mm
Exducer Dia. : 52.50 mm
Extend Tapered Tip Exducer Dia. : 56.02 mm
Tip Height: 4.05 mm
Super Back Height: 0.00 mm (Flat Back)
Overall Height: 22.60 mm
Bore Size : 5.10 mm
STD or customs size : Custom size
Blade : 5+5
Trailing angle : 60 Degree
Bore Type : Through
Fits OE Comp Hsg : Modification required on OE comp housing
Cutback : 0.0
Rotation : Forward

I assume this is a shoe-in with potential minimal machining of the housing, since this one is allegedly 1mm wider.

Thoughts?

Edit: just found the wheel dimensions for T-bird VC-32 from IHI and VJ11:

I wonder how precise those guys are with their 40mm inducer.

Been chasing a few manufacturers out of China/Taiwan, as well as U.S. The options are there and don't cost much if there is enough interest. Lowest quantity I got so far is 5 units for $55 each with $35 shipped to my door (lead time 4-6 wks). That was from mambatek (reputable ebay seller). Otherwise that 40mm wheel is readily available on ebay as well. Let me know if anyone is interested.

Small vs what? I've put close to 200 wheel on a mustang dyno on my VJ11 on less than 10 pounds of boost. When I put a t-bird in, it was a night and day difference at the same boost level (i do need to get retuned, as was running a bit lean). I am running this on a ZX2, not a MX6, so it might be different. T-bird was a straight bolt-on vs trying to figure out new mani and piping for a T3/4 or whatever else. Got one for $250, but turned out to be a lemon, leaking from the turbine side, so was researching the wheels to slap on my good VJ11 (and balance it) and re-use the tbird comp housing. Couldn't find any manufacturer's specs on the forum, so really just sharing what I found.
