about the boost gauge:
I don't know if the brand is sold in the states, but the brand is SLM.
I made the choise because it is the best fit to the gauge of my LC-1.
about the turbine housing:
I'm not complete surtain that it is an tb2525, I bought it from a guy in the Netherlands that also comes to this forum: Gredddymx5.
A GT25 based turbo will fit the greddy manifold, the standard DP will nof fit.
In my case that didn't botter me because there is no bolt om solution for my B6 nbb mx-5.
The a/r ratios on the turbine and compressor housing gives me the inpression that it could have the same specs as an gt2554, but for that I'm not shure.
The a/r ratios are the only pieces that are still the on the housing.
If someone now a webstore in europe for a actuator bracket that is mounted to the turbinehousing, I will be glad.
Otherwise I must order at bell. Not that I don't want to, but shipping cost are a bit high only for a bracket.
