Marty's road to ~450WHP

Yes, that is exactly what I found out. All the competent shops are full till after summer. I'll try to source an extra engine and build that one.

For now I am working on the exhaust. My FI exhaust is too short because I installed a nismo bumper. So the end tips will be put back about 2 extra inches.

I will also install a butterfly valve bypass before the end mufflers. I didnt want one with an electric motor, so I went with a boost pressure actuator which opens at 4 psi.

I'd like to regulate the air pressure to the actuators so that I can also drive the car more quietly. Prefferably electric with a switch in the car. Any ideas for some kind of open/closed switch which I can connect the vacuum lines to?
