Rate my turbo placement.
No, seriously... anyone see anything glaringly wrong with this? Other than the 10pm pic quality, of course. I haven't started fitting elbows yet, so its not too late to make changes.

I would place it slightly further forward unless there are conflicts in that direction. My reason for this is access to downpipe to turbine housing nuts. If you believe that access will be no problem then use the location you already have.

Appreciate the input. I don't think access to the DP nuts will be an issue. I know its hard to see in my HD pics, but the inlet is pretty close to the p/s pump bracket as is.

No pics, but took her out for a first drive this fine eventide.
... and quickly ran out of injector.

Up 'til now, I've finished out the intercooler plumbing, finished the exhaust from downspipe to tailpipe, finished up the coolant reroute plumbing, installed the Warlboro 190, and adjusted the tune in the MS.



What? I tried to tell you that I'm bad at documentation.

Alright, fine... Here's an 'after' pic. It's not done, but here it is:

It's running on Fleabay Mitsu 650cc injectors now. Fairly well, but I get a fuel cut at anything over ~150kpa MAP and/or 8.6 mS injector which equates to ~34% DC. Anyone experience something similar?
Go easy, I know I have some cleaning up to do on the VE. But if you see why I'm experiencing fuel cut, please do tell.
Nevermind, just found the overboost fuel cut settings. Color me embarrassed.

Although I am not familiar with your turbo, your spool numbers seem to indicate a problem.
5psi at 2500rpm may not be bad, but just 7psi at 3500rpm and 9psi at 5000rpm is just not right.

I would try wiring the wastegate closed to see if you get different results (but first set the overboost low so you don't break something).

FWIW my huge, ancient T04E-50trim is 3.3psi at 2500rpm, 6.3psi at 3500rpm and 24psi at 4400rpm.
