DAW 6769 help with setup

[MPJR03]

This is my current setup, it’s still in the shop being put together. I’m aiming to keep things conservative with this build—what would you recommend I focus on? Trying to keep a OEM look.

You don't need the LPFP, you will max out your transmission before the LPFP.

If the CSF cooling package isn't installed yet, sell it. It's worse than OEM

Did you finish the car? Results?

Everything is fine except the turbo! I’m trying to fine an oil feed regulator to lessen the pressure of oil that’s being sent to the turbo. I got the oil pressure restrictor but it wasn’t enough to slow it down the pressure was still to high.

I used the Turbosmart inline oil restrictor. It doesn’t go above 40-45 psi, regardless of throttle response. I cut off the factory OEM oil feed line, placed a new fitting, and ran two -4 lines to the block and the TS oil restrictor. No issues. Cleared up my smoke almost immediately.

Somewhat off-topic, and I do not intend to disparage DAW in anyway, since I know people shit on it here already - but is an oil restrictor required for any other bigger turbo for the 600-800 range? It seems like the only times I've seen an oil restrictor being needed are for DAW turbos smoking due to oil.

I myself also formerly had this issue, but I'm not sure if it was due to my faulty oil pump (replaced now) over pressurizing the turbo, poor crankcase ventilation (wasn't running a breather then), or the DAW UFX having poor drainage (what I think is the issue).

I know Trevor from DAW posted a video on Instagram on what could cause the smoke, but it seems like it can also be attributed to being a poor design of the turbo if the solution appears to be needing an oil restrictor.

OilFeed restrictor generally depends on bearing type, not wheel diameter. Ball bearings need a restrictor or pressure regulator, journal bearings will generally gulp as much oil as you can feed it, since oil is intended to go over, around, and through the floating bushing.

Ok and unless I'm mistaken, aren't DAW turbos journal bearing?
