Well I guess if you don't have one to begin with that would be a whole different ball game. I already have one, it came with the car. So it's actually WAY cheaper for me to rebuild it (basically new gaskets ~$50, and Spring) then to get a new Tial.
Well I've decided to keep mine and rebuild it instead of going with the Tial for now. I can put the difference towards a better intercooler.
