View Full Version : 2004 WRX questions

Looked and test drove a 2004 Subaru WRX today.

At idle the engine pulled 10 inches of Vacuum, now is that normal?

The Supra pulls 17-18 inches of vacuum so maybe it's because its an 6 cylinder?

^^ haha well see

In 3rd gear it was boosting at 13-14psi.

I dont know if it's me, but 10 inches of vacuum seems a little low for an engine....

I think my STI pulls around 10psi vacuum at idle. The stock boost gauge reads out in MPa, and it is at -0.07 which I think is 10 psi?:confused:
