240Z Turbo Posted March 15, 2002 Share Posted March 15, 2002 took out the racegate and replaced it with the 60mm HKS GT wastegate. I did this because the turbo's spooled very quick and I suspect I would see unwanted backpressure because the housing were undersized. So, enter mr. HKS 60mm guy! I also ported the stock 20mm hole to about 35mm or so and did some nice smoothing into the wastegate hole. Finally, I cut out the #5 runner because it was angled towards the manifold stud and I couldn't get a wrench on it. I had it come out about 1" before I angled it into the collectors.
