Default N63 high miles, help me find a solution. - 10-08-2021, 06:06 AM

I have a high mileage f10 550i xdrive it’s a 2011. The n63 as we all know performs best on paper. Now I’ve been looking into numerous things I can do to extend the life of my car without actually replacing it being that it’s paid off.

First solution would of course be doing the labor intensive valve stem seal job. Which I was quoted from a local indy mechanic $3000. Which is actually a bit more reasonable than getting it done at bmw which would probably charge me $4000-5000 more

Next would be getting the crate motor from bmw costing 3500 which is (again) reasonable but then to add new turbos to that and other new parts (I’m spending a lot before labor)

Next would be that I could just stick with what I have and essentially do a rebuild. (Again a lot of money)

Now I know all of these are costly, but I’m pretty torn on what route I shoappvalley tutuapp tweakbox
uld take. I take care of the car it runs as well as it could for having tired turbos and bad valve stem seals. The car again has been paid off for quite some time too. Any n63 owners that can give me any advice on what they’ve done outside of the bmw ccp?

I would get the crate long block. All new, no bs.
Are the turbos bad? If not keep them for a while. If so, send them to Pure for a Stage 1 build. Or if you’re going on the cheap, scour eBay or salvage yards for good take offs. The other option would be S63 manifolds and turbos, but I don’t know how the original N63 would deal with twin scroll turbos.
