Well once my 3" downpipe is fitted then I've basically come to the end of my planned engine mods

(just bolt ons) So got to find something else to keep me occupied with the mr2.

So I was thinking about gauges, which I dont know alot about.

I was thinking maybe air/fuel mixture gauge and oil gauge.

I already have a boost gauge.

just wanted to know which ones are worth getting and are they easy or difficult to mount and install?

Thanks
