M42 turbo fact thread

[MVincken]

how is the position between the wheel and the sensor?
I don´t know if you changed it, but if it´s too far away it won´t send a signal

[JRW21]

Position is the same. That's one thing I left alone.

Got it sorted out and RPM synced now. Does anyone have a solid base tune they wouldn't mind sharing?

Where would I get my ecu tuned for my turbo build? I'm from east stroudsburg pennsylvania. No one has been able to answer this question for me. I drive a 95 bmw 318ti

Burkard, that is a beautiful setup. Don't see too many low mount turbo setups. With ITBs too...did you boost before ITBs and then add them later? Mostly curious how it affected throttle response and if it highlighted any shortcomings in the stock manifold setup.

95tisofly - unless there is a member on here close to you, you will more than likely just have to call around your local tuner/dyno shops to figure out how can help you.

I'm honestly impressed it doesn't blow all the boost out past the ITBs

[captain awesome]

So I bought this partial Mosselman kit and I'm getting some of the details figured out before I drop the motor back in. Unfortunately a ton of pics are going in the toilet due to photobucket and I'm figuring out where my oil drain should go. I see there's a fairly large bolt at the back of the block, can it be used? Also with this being a lowmount setup, how does it drain properly if it's on a lower plane than the drain does that require a scavenge pump or will a simple check valve be sufficient?

Look at this setzy thang.

Looks like I'm an idiot, as the bolt mentioned above is another drain plug for the coolant system. I'm either going to try to fit a bulkhead fitting to the higher point of the oil pan or have a fitting welded on. Still not sure if I'll need a scavenge pump or if a check valve would be sufficient from drain back into the turbo.

That depends entirely on how low the turbo hangs with that setup, it's tough to tell from a pic of just the manifold and turbo but it looks to me like it's very close to being too low to not be scavenged. If the turbo drain port is at or even slightly above the sump oil level, it's too low.

Thanks!, i did the swap with the Itb´s first, i never run the car with the stock manifold.

The itb´s run very well, but i was always fiddling with the idea of supercharge it.

The superchargers are not very common here, but there´s a lot of people, with a lot of knowledge with turbochargers, so i decided to run a low boost setup.

It is a very fast car, and can outrun a lot of big fishes.
