Send us your Hahn-Mitsubishi Turbo, and we'll install a Precision 39MM external wastegate on it. We'll remove the stock internal wastegate, and also provide a stainless-steel dump pipe. Primarily used with our Zoomie-style short exhaust pipe. Can also be used with our full exhaust, be sure to also send your Zoomie or full exhaust downpipe to be fully integrated into the conversion. Your turbo returns to you in bolt-in ready form. All machine and welding work included, along with a full selection of different pressure wastegate springs.
