I am currently running a hybrid K03….the GTT unit with the billet RS6 wheel in it on my 1.8T with E85. Peak of around 27.5psi tapering to 23ish at 6,500 rpm. WG duty cycle is pretty much maxed to achieve these numbers. I was given a used IS38 from a 2015 Golf R. Do you guys think there is enough of an increase in flow to justify the time for me to make lines/adapters etc to fit this turbo onto a 20V? Or should I save the IS38 for an MQB car someday and just buy a bigger turbo for my car?
