turbo sizing

[rockfish]

How much difference is it in a hx35, hx35/40, and a s300g, some say the difference isn't worth the money, others say the s300g is outstanding. With a 3 1/4" banks exhaust brake isn't it like a bottle neck in a 4" exhaust, raising the back pressure like a smaller turbo.

I would get the hx40/35 hybrid. I would say it is the best for your money. Only thing you have to worry about it "barking" it, because it has the small hx35 shaft. The s300-series have larger shafts and are more forgive and usually can spool a little quicker. In the end, it is all up to you.
