GT3071 turbine comparisons

[Boosted Esky]

Just wondering which version of the GT3071R turbine would perform best on a 4cyl 2L engine.

The full size 60mm, 84 trim. Or the cropped 56.5mm 90trim aka GT2835 aka GT3071R-WG.

*PLEASE NOTE * the CHRA will be fitted to a HKS style Mamba turbine housing, not the godawful T28 style housing.

Thanks

The 53.8 in 47 ex would be the best turbine wheel for SR20det, run that in T2 .61 turbine housing externally gated.

That's what I've already got on a Ford SOHC engine. It's a GTX2860R GenII in a T28 0.86 with the flapper welded shut, 38mm external gate. It's choking at 300+whp so looking for a bigger turbine.
