   I have an 08 Mazda speed 3. The turbo is bad and causing it to smoke really badly. Will this rebuild kit take care of that issue. Also will the 50mm wheel fit it and what will this do for me performance wise? Also any supporting mods to go with the bigger wheel? Thanks!

   I am wanting to upgrade my 2008 mini cooper s. The dealer said the waistgate is not sealing and would need to be replaced built. They want an arm and a leg…While doing that I want to upgrade. What would be the cost for the best internals and a compleat rebuild. I still want it to be able to bolt up to the factory sized down pipe and everything though. Obviously the intake side of the turbo would have to be resized to the new size, which from what I saw of YouTube for mini you guys do 50mm. Do you offer an adapter to hook up to the larger intake dementions. I have an AEM CAI (https://www.aemintakes.com/mobile/product.aspx?prod=21-699C) so how would I get the turbo inlet coupler elbow to 50mm to fit the turbo upgraid? Do you sell that also? Price for everything you can offer, and suggestions for what you can’t.

   Thanks,
