can you run an aftermarket cam like a toda spec a or jun type 1 on a turbo car will it help out or stay with the oem cams for turbo or even bigger than the spec a or jun 1

 

We have had very good results with JUN Type 2s, although, tuning is tricky. The torque curve is the flatest we have seen to date...super flat torque all the way to redline. If those are not within your budget, I know of several racers making very big power with stock GS-R cams dialed in.
