Whilst my engine is out I thought I would port the internal waste gate of my 3071 to help with boost surge. Though I had mapped round the problem and the car pulled smoothly on part throttle it would sound like a "steam train on full tilt" :lol: :lol:
I've read a bit on the affects of porting but not seen a good post on practically how to do it.
What I know is you take the exhaust housing off and port the wg hole wider and the internal side of the casing to for flow. This could be a lot of old nonsense though. can anyone point me to a good link on the best way to do this. Ideally for a 3071 but I'm sure I can work it out.
The othe option is to make the WG hole even bigger and install a bigger flapper valve too. This sounds more effective but potentially more prone to mistakes so I imagin this should be done by a machine shop?
