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.
 
I believe it was LIPD that was doing them a while ago but I think now you end up just having to buy a modded turbo. I don't recall anyone who is offereing them anymore. I could be wrong but that is what I recall.
 
I saw a post on another forum and give industrial injection a call and see what they say. They would be the only ones I know of that might still do it without sending the turbo in.
 
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.

There is still some machine work involved. I'm working on this right now.
 
what about an exhaust housing off of a gt40. Pretty much you need to turn your gt37 into a gt40vgt. all you keep from the gt37 is the vgt center section, they both have the same frame just like the gt42 and gt45 do
 
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.

I may have come across those parts for next to nothing. Right now the turbo is built except for having the exhaust housing and tonight I pick up the 03 exhaust housing. Shooting for the weekend to have it on the truck.

Also I’m currently working on making a 04 exhaust housing work with a 03 wheel. It is more involved than I thought. Those pins don't just fall out:bang. I'm contemplating having them edm'ed out or just machining them out. Not sure yet.
 
Im glad the direction this thread has taken everyone. I have not ever thought about bulding a turbo just buying one from a vendor. The information swapped here is great. I have learned a lot as I hope other have too. Thanks everyone! :Cheer:
