Hi all,

Old member here, been off the forums for a couple years.

My old N63 spun a rod bearing so while I have the engine apart I decided to upgrade turbos.

I have for sale my old set of Alpina turbos. Please read everything first.

Full details:

They will fit any N63 (non-TU, TU2) engine.
They were fully working when removed. No noises or any problems.
They should be rebuilt. The radial shaft play is probably right on the border out out of spec. Axial shaftplay seems fine.
The compressor blade edges show some erosion. Personally, I ran the turbo like this for a long time and this is why I imagine they need to be rebuilt now. But, with a proper rebalancing, I would have confidence running them again. They should last a long time if balanced for and I don't think you'll have any performance impacts from such small erosion on the blade tips.
They are tapped 1/8 NPT on the outlet for meth injection. I have plugged and sealed the hole with a threaded plug that is removable in case you want to go this route in the future.

The reasons above are why these are priced so cheaply. Consult your turbo rebuilder, but, if they are confident they can balance for the errosion on the blades, you have yourself one cheap set of Alpinas.

Attached also is my dyno sheet when my only mods were JB4, intake, and Alpinas (E30 fuel, 19psi, AWD).

Asking $650 + shipping.

Nice deal!
Mine need to be installed still, sitting like new in box at my office. Not having a garage sucks!!
That @ wheels? What kind of power were you getting with other mods? What turbos you going to? New motor or rebuild? Details!

GLWS and build

It does, I was there for a while with this car and working out in the driveway/street is no fun for sure!

That dyno was at the wheels (AWD car). Since then I've done meth/downpipes, but never made it back to the dyno when the car was running well (I went back once but my meth system was crapping out).

I picked up a set of the N63Intake hybrids now.

And I'm rebuilding mine, didn't want to wait around for BMW. Waiting on the machine shop to finish up my block which has gone 1 month over target

(Should be ready any day now!)

I'll try to be more active and post more about my new setup when my car is back on the road.

The main bearings had no damage, but two rod bearings on one journal both spun. The consensus seems to be oil contamination causing a flow restriction internal to the crankshaft preventing that journal from getting adequate flow.

I changed my oil every 4-5k miles though, so it was probably more a fluke as there was no clear sign of what the contamination came from
