Emma Watson and 2 E34's (Low Mount Turbo M50 Project)

[Dj Buttchug]

The build continues as we work out kinks and smaller problems. As of now we are up and running on 10psi. Engine tuning has been complicated with the Link ECU. A very powerful controller has some downsides (learning the software) has been tedious. We had issues with dashpot settings and engine idle undershoot. The car was dying off decel, hunting ect. Finally got that sorted with idle base position settings.

Screamer pipe setup I had going is fully out now due to the fact that is sounds like complete shit. As soon as It opened up the first time I instantly hated it. To fix it I fabbed up this setup to pipe it back into the exhaust.


Engine bay is done for now. I need a coil pack beauty cover. If anyone has one let me know.


And now the best part so far. F30 340mm brakes. Should be fun times.

Moved under her own power this last weekend... Clean finally after 8 months

Read your recent updates on the last few pages, looking good!

I'm going to go back and read from page 1, purely for the Emma Watson pics of course. 😉

A shot of the lightweight flywheel from ClutchMasters. Working on a diff rebuild for the car as well. Using cryo treated 3.15 ratio with a 40% lock clutch pack kit from RacingDiffs. Old clutch plates looked good in the carrier housing. Waiting for the proper side shim sizes to arrive and we should be ready to install the diff and drive the car finally.

Because this should be on every page.

Nice. I missed this one, you and I tackling parallel turbo E34 builds with totally different paths. Sucks that you had to fab that crossmember, somehow the AL ZF crossmembers were still available new and fairly cheap last year.

I think your brake booster check valve is backwards?

Nah it's good. There's an arrow on it, visible from the front, hard to screw up.

A few nights ago I fabricated a transmission mount as the one I needed is now NLA... Lots of sitting and pondering the goals with this car. The daily driven comfort must stick around no matter what. All in all we are on way and hoping to be commuting to work and back in the next weeks.

Running a bottom mount turbo in this engine bay ended up becoming more of a task than I had anticipated. With the turbo mounting so low I ended up with major oil drain back problems. This relay setup here runs the Turbowerks scavenge pump for 3 minutes after the car is shut off. Adding this to the factory relay box was a bit time consuming but it turned out clean in the end. The second photo here is a 95% finished engine bay.


Specs on engine as of now:

Journal bearing GT28 Oil and water cooled
OEM volvo intercooler (2008-2010) XC90
Turbowerkks EXA oil scavenge pump
Bosch Green Giant fuel inectors
OEM fuel rail with factory FPR block off plate
Turbo Smart FPR 6 adjustable FPR
ClutchMasters FX350 clutch with lightweight flywheel
ARP headstuds (Stock headgasket)
2.5 intercooler piping
SPAL slimmy fan with e36 M3 aluminum shroud modified to fit correctly
Knockoff BOV I had laying around
2.5 single exhaust downpipe into factory resonator and muffler (changes here possible later but I want the car quite)
Somewhat decent external wastegate (ebay) We will see how this plays out...
Mechanical boost control
Linkg4x ECU
AEM wideband
255lph fuel pump

More to come.

Moving foward with the build here is a photo dump of some things that have happened in the last few months. Car is now running on link G4X standalone. We are still on jackstands in the garage but as soon as the diff is built and finished we can go back together and start some more tuning.

Cold side housing clearing the steering arm was a bit of an issue to start. Sorted now with some slight mods LOL
