I entertained this idea for a bit but decided against it as I have yet to see any real performance numbers or results from a custom turbo. If you have any companies you could refer me to that might be able to provide possibilities it would be greatly appreciated. On the contrary, I don't think 18k would be able to get me a very reliable custom turbo kit that would offset the stage 4 on an e46.
