Does anyone still make upgrade turbo compressor wheels anymore? Im sure I remember seeing them a few years ago but can't find anything now.
Beans did.
Forgot about them..... I always associate beans with the 7.3 stuff.
why don't you just call a turbo shop and get a wheel from a GT40 i'm almost positive they bolt right up, they are based on the same frame as the GT37. The GT40's have 3 different compressor wheels with exducers of 88, 94 and 102. You will also need the compressor housing to match the wheel. The other thing you might consider is getting a exhaust turbine wheel from an 03 it is larger than 04-07 and it will whistle like an 03
I bought w used 03 turbo cheap and am going to send it out to be rebuilt. I figured if I am going to do that I midas well see if I can't upgreade the compressor wheel too.
Thats what I have the GT4088. The whistle is stupid even with a muffler on it.
a compressor housing and wheel from a gt4088 would be nice with a set 0f 155cc or 190cc injectors and put you over 500hp. They make different A/R on the compressor housings depending on where you want the power to come in.

you cant use the turbine housing because the vanes are built into the stock one. i dont think the housings mount the same either. a gt4088 comp wheel and compressor housing / backing plate will work but good luck finding those parts, garrett only wants to sell them in bulk.
