Sorry for the late reply, I've been away with work the last month, and i won't be home for another month, Halim is still waiting on my datalogs, I'll post an update as soon as i can once i return home. But i have been running 24psi on 98 Ron (93) and its stupid how quick the car is on pump gas, not to mention loud! Once the e85 tune is sorted i will be heading to my local BMW tuner for a dyno run and then off the track for a qtr mile time.

I am back, so i have an update!

Clearly running a 100% E85 tune on the Bootmod3 platform at 22psi on the stage 2 turbo shows just where our HPFP Maxs out, huge bottleneck! After 3200rpm the HPFP goes from 2888psi to 1324psi and continues to drop at 4K the car literally acts as though i have a 4K rev limiter wont continue unless i reduce throttle input! So there you go HPFP is SH!T Next stop is to buy the Fuel-IT CPI kit, car just pulls even on 98 Ron @24 psi it hammers! I am yet to flash the XHP Tranny flash but i have flashed the PTF transmission flash and thats made some awesome changes! Dyno run. Will be in within the next 2 months, unfortunately these sorta of builds take some time to complete!

Yes i am still using the OEM housings but they have been machined to fit the Larger turbine wheel and Compressor Wheel, PS2 apply the same principal. Yea i got the Compressor Housing Machined at Precision Turbos (Blacktown Area NSW) and the Turbine Housing down at AGM Engineering (Emu Plains NSW)

Only thing i found annoying was Precision Turbos had to cut the outlet off to machine the housing, although they can re-weld it back on. i chose not to as i went a slightly different outlet design had a 2 inch to 2.5 inch extender directly welded on.

A break Down on costs
Turbine Housing Machining ($770 AUD)
Compressor Housing Machining ($150 AUD)
Turbo Uprated Rebuild kit (inlcudes Better Journal Bearings and Thrust Bearing Upgrade $300 AUD)
Turbo Balanced ($150 AUD)
Compressor Wheel ($153 AUD)
Turbine Wheel ($170 AUD)
~ Prices May vary slightly ~
I also bought the parts and rebuilt the turbo myself.

Are you doing anything to help with mitigate the oil starvation/pressure loss under hard braking or hard left turns? I'm getting this pretty bad after my last session on track and am looking for some ways to reduce this. Most people recommend overfilling a bit to help with that. I'm also running 5w40 over the OEM fill of 0w20 which seemed to help a bit but I got hear whining coming out of turn 11 at laguna since there's walls/garages there to bounce back at me.

Already sorted that problem, see page 2, oil pan baffle installed makes huge difference, i also recommend running 10w 40 fully synthetic with easter and Zinc in it (penrite 10 tenths racing oil) helps alot too. Having good rod bearings i.e TRIMETAL racing rod bearings and low friction coatings on these bearings and the piston skirts also help low oil situations but the baffle is the absolutely the only best way to mitigate this issue, i know the xdrive aluminium oil sumps are different designs we don't have xdrive in Aus, just the plastic oil sumps for RWD, so the oil baffle design for the Xdrive sumps may have to vary slightly

Ah I missed that on reading through your thread. That's a nice idea! I need to track down some photos of the xdrive pan but I'm hoping to do something similar with my setup. I don't have a built motor yet but I'm running thicker oil than stock (5w40 vs 0w20) but still ran into oil pickup issues on left hand hairpins and sweepers.
