Shearer 50Trim vs. HKS GT3037s
race gas isn't readily available, but what's your pump gas, like 98 octane?
A more direct question may be what boost do you plan on running? The 50 trim has been proven time and time again to show the best area under the curve at boost levels of 22-23#'s, which we can run on 93 octane here in the states. If you have higher octane and hence higher safe boost, a larger turbo may be an option. But if not, the 50 trim is your best bet for a 2 liter.

One of the reasons people have such poor performance from the HKS 3037 is due to the USA version coming with a .87 backside. This backside is meant to be used with their stroker kit. A .73 would work much better with a 2.0l.
Performance wise, they are going to be very similar.
