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

Is it goy or is it not gay

That is the question.

[OSAH racing]

I agree, What a great looking street car.

[2mAn]

Car looks fantastic. Hope all the hard work makes it a smooth process from here

Another 30 miles of engine break in done. Making boost at 2400rpm. Very nice for a street car.

However, I would like to see more air moving past my cooling system. Earlier a discussion was had about hood vents. I have ordered some from Condor. One on each side paint matched to keep the rice down. It is the only effective way I can think of to reduce the positive pressure in the bay.

That's gotta feel good- nice to see you tracked hours too. When I tell someone how many hours it takes me to mechanically revive a shitbox E30 most just laugh and assume it's not a real number. The opportunity cost of building these cars is real

Totally. Things add up so quickly. Only those who have done it really understand what it takes. Its safe to say I am officially burnt out with custom projects. This will be the last turbo build I do ( at least for a very long while) With my first kid on the way here in November most of my time will be taken up.

Celebratory brew and a much needed wash after over a year of building.

We have some small tuning quirks to sort out. The idle control lockouts and decel overrun is causing the engine to randomly stall when you depress the clutch coming to a stoplight. I built a new VE table mirroring my E30 and its pretty damn close. LINK PNP is complicated. The Aussies built this ECU after ripping a couple blizzies. This morning I flushed the cooling system with distilled water to remove any debris left in there from the build. A good bit came out in the fluid so I am happy with that for now. I will do an oil change in about 100 miles. Castrol 10w-40 CONVENTIONAL.

I got my hands on some pretty slick quick disconnect oil fittings for my oil cooler so I will be installing those soon. It will allow me to disconnect the oil filter distribution block during an oil change without having to fight the AN lines.

Then soon after 500 or so miles of break in I will take it to the dyno and post a chart. Still to finish is some sort of fix for the cars paint (wrap the stock color or try and save whats here) I also have some ideas for a front splitter, rear diffuser and E90 skirt trim to finish this off.

As stated previously in this thread many times. Do not attempt this build unless you are ok with dragging your nuts across broken glass for 2 years.

Total build costs as of now (obviously no labor)

+/- 750 hrs of research and wrench time. (Probably conservative here as it is likely more)

Total estimated cost all in as the car sits. +/- $37,500.00

[Dj Buttchug]

The stepchild is out!!!!



First 5 or miles of break in complete. Kept it under 5k and no more than about 6-7 pisseyes.


NO LEAKS



NO SMOKE FROM THE EXHAUST.





When the M50 is all lined out this photo will have about 900 HP in it.


Time for a much needed wash.

Subtle flex using $26 of gates barricade for your airbox grommet

Lookin good!

LOL make no mistake. I am broke.

Good point I should say. Not the ideal material to use for sure.

Which? Delvac no. The break in oil no, I looked it up, it was Havoline 10w40.

Right. Reason I ask is because we have had several instances where people at our shop are running synthetic oils in these older cars and every gasket sweats, leaks start from all over and no matter what you cant seal the engine up. Switching to a good conventional stops all the leaks ( or a good majority of them) My plan was to start with and potentially stick to a conventional Castrol in my E34 engine. Ive had the same issue with my M42. Apparently the molecules in the synthetic oils are smaller...??

I wonder if conventional oil would reduce your oil consumption problem but it sounds like you had ran that prior and the results are still the same.

[varg]

Is it synthetic?

Which? Delvac no. The break in oil no, I looked it up, it was Havoline 10w40.

[Dj Buttchug]

I've used Mobil1 (15w50?) and Delvac 15w40 (mostly this) in it. Delvac is cheap and meets the required standards, which is important when the damn thing won't stop leaking or burning oil. For break in I used whatever the metric mechanic engine break in instructions pdf recommended.

Is it synthetic?

[varg]

Yea. Id say the only thing I havent had to touch is the AC lines.

Ive been thinking. What engine oil are you using in your E34?

Yeah that hot side is crowded no matter what you do. It has been a battle for me since day one. I'm probably going to have to revise my AC lines somehow to get them to hug the firewall better and mount the service ports higher, like where the fittings are now. At least it isn't like the E39 though, where the ABS unit is mounted where a turbo belongs.
