redline

I've got a 1990 MM 5 speed, does anyone know where the 4g64 redlines?

Hook up a tach and it will tell you

I have a sunpro tach installed, I'm trying to match the redline on the tach with what the engine redline is. the tach has an adjustable redline

Typically an engines redline is between 5500 and 6500 rpms the latter being max rev before bad things happen however 4 banger do tend to go higher I'd still stick with 6500 max.
