Ill assum by the part number that it is a ballbearing center section "37R"

Which should be half way between a 35r and a 40r.

In reality what it probally is, is a 67mm wheel stuffed into a 35r housing. Unless you have one hell of a built motor sleeves bad ass rods and pistons and a 10-11k rpm top end then no you cant run that.

Nix that they are just idiots and call a GT30R by their own name. Its a 3076 and thats what I made 440hp on my sr with. Super nice turbo it will pull all the way to 8k.
