MitsuStyle - View Single Post - anyone tried a VGT or VNT turbo on a dsm?

There are some limitations though. A motor can only take in so much air, if you spool a big turbo too fast on a small motor, you get compressor surge. GT35R/61mm turbos spooling normally have compressor surge problems on 2.0l DSM and Evo motors, unless you have a ported shroud/anti-surge cover, which lets some of the backing up air flow back out the front of the turbo, instead of causing the compressor wheel to abruptly stop.
