I've been giving it a lot of thought lately, and there is a shop in my region, that does custom upgrades of turbos. I have a pair of oem turbos that I bought from the black market here long ago, but my oem turbos never failed (112K tuned track/street miles). I'm wondering the pros and cons of giving them to this shop, to machine, and upgrade, vs buying already made stage 2 turbos from vendors. I'm certain parts/labor should be around $1,000-1,500 max. Any thoughts?

U are better off looking for proven upgrades

I've been going the custom route lately, and it's been a good experience, so why not turbos? With stage 1 & 2, all your doing is machining existing hardware, and upgrading wheels, wastegates, etc., right?

Due to the turbos design it is A LOT more difficult to do to than most people think. It is much more involved than it is on other platforms and since you would be shouldering the cost on your own it will become VERY expensive very quickly. There is a reason that companies liked Forced Performance declined to enter the N54 hybrid turbo market.

Could you elaborate on the dificulties in machining it? I noticed on this shops website, pictures of various small sized mitsubishi turbos that they have upgraded. People have been doing custom singles on here, so why not custom twins? Are you a vendor for upgraded turbos?

The difficulties lie in the fact that the turbo/manifolds are one piece and the WGA actuator design. For most shops simply rebuilding or putting bigger wheels in a housing is no big deal but BMW made this a big deal.

Hardware wise a custom single turbo isn't a huge undertaking, when it comes to a kit well enough designed(and built) to market as a ready to run setup is another story.

We sell Vargas turbocharger kits and will be making some big announcements about our single turbo kit in the near future.
