Hey everyone, had a question for everyone who has a turbo in their 280Z. Do your heater controls suffer from vacuum loos when you get into the boost? Should I install a vacuum pump from the 280ZX donor car my engine came from? If so, where do I connect it to? Any help you can give is so appreciated, we do my swap in 3 weeks, just want to be ready for it.

I used a one way valve before the vacumme tank. Works fine!

My '78 already had a 1 way valve before the tank, so you don't lose your vacuum on acceleration. Use it as is no problems.
