Was poking around the site I ordered my recent vacuum pump rebuilt kit from and came across these. I was impressed by the quality of the kit I ordered and by the looks of these they seem smoother and of a higher quality than any other ebay/Amazon/FCPEuro cast. The company is located in Utah so maybe if someone local wanted to take a look it might be worth it. I did some additional searching and it seems these haven’t been mentioned before and just wanted to toss them up if anyone was planning this service soon. I plan to in the near future and see these as a promising option. Cheers!

I remember somebody mentioning options like this before and I knew there was a caveat of sorts. Sure enough their site lists: "only compatible with supercharged engines" so no luck for those of us who have the naturally aspirated ones. Would be interesting to hear if these work (well) for the SC ones though.
