M54B30 Turbo E85 Build

Well i've been harvesting parts the last 3 months as i knew something was very wrong with my M52B25 , turned out to be a couple of broken pistons..


Anyway so here's my build ;


Planned Setup :

E85
Custom Forged Wiseco Pistons
Stock head for now
MN H-profile Conrods
Injector Dynamics 1000cc Injectors
SPA Turbo Manifold
Precision 6265 turbo
NUKE Fuelrail/FPR
??? Fuelpump


(most likely have forgotten something, but it's all in the pics)

All will be controlled by 400+feet of wiring(my brain hurts from doing that) and a Link G4 Extreme

Anyways onto the harvested parts;

MN IC

Cheap Ebay turbo (as i cant buy the Precision until i get my S/C sold)

Tial Wastegate

Knock-off SSQBOV

V.A.G Igniter+Coil

Vacuum + FPR

Pistons



MN Rods

Crank(yup it's brand new, didn't want to take any chances on a used one)


Anyway progress is pretty slow atm as i need to have the pistons adjusted for the conrods (they have about 0.5mm of interference) and i need to take the head apart and redo all the gaskets aswell as have it checked and maby decked(dunno if that's the right word for it?)

Lol

The turbo is mainly so that i have something to wear in the pistons/build an exhaust by , as i said it will be replaced once the S/C is sold (i'm out a tad more than a hpf stage 1 so far)

Oh yeah and E85 is $7,50 / gallon over here compared to $11 /gallon for regular, give that e85 burns cleaner(we have REALLY strict emissions laws here) and it has a higher octane rating... well there really isn't any option

fair enough, should be a good thing to get a baseline tune down for too.. e85 sounds like the clear choice for you, I figured Sweden's emission laws would be super strict. What are your turbo plans for the future? Are you sticking with that injector size for sure?

Im not sure about the injector size, the need for more power will always be there i guess

Though having spent so much money on this my next purchase will be an 118d so i can use that as a DD lol

Update , MN rods are a bit too tight for the wrist pin , having it shaved down as we speak.
Pistons needs some modifying too , apparently wiseco thought 2mm of space between the wrist pin and piston-underside would be enough... it's not

Wiring harness is as good as finished

Just need to wire up like 4 functions (speedo in/out, some DI for Launch control and some more )

Best part is that it looks almost stock

In!

E85 should be interesting, I know it makes the most sense.

I wish there was more E85 stations locally, or I'd switch. Only have one in MD

Got some work done today.
Got the crankshaft mounted in the block & tested the M50 main-studs.. turns out they don't fit
Also bought a 13mm drill + a 25mm "shaver" so i can tap an oil-return tomorrow.
HPF clutch should be here tomorrow and my AN4 oilfeed for the turbo is at the postoffice.

Didn't bring my camera but my buddy took some phone-pics:
