I'm wanting to build a similar setup to the UPS III kit. I understand it uses a T03 turbo. These turbos are quite cheap to get, but I'm not too terribly familiar with what trim I would need. I see people running as much as 35psi with Garret T03s on TDs on these forums, what model turbo is used at that level? I plan to initially run 25psi or so with an 11MM pump and my Sprint 764s. I might just get the UPS III chiptuning software, unless I find something better in the meantime.
Thx in advance for any info,
