83mm or 87mm Turbine Housing?
 

How much of a difference does it make really?? is it worth the extra 350 bucks? street car with half bridged cosmo .. Bw 372 or 375 leanin towards s375.. any input thanks

is the 375 just the T4 version of the 475?

believe so

If it's a street car you'll never take "advantage" of the 87mm wheel. I've built three s375 turbo kits for customers and they have all had great results with the 83mm wheel. Don't over think what doesn't even make sense here...

I got a couple PM's as far as fitment. Pay a professional to build you a manifold. You'll even be surprised how many "professional" turbo kit companies manifolds require you to modify your chassis or motor mounts to fit. Anyway here's a lager frame turbo and the tight area you have to deal with...
