New-to-me 2008 Yaris 3 door MT

[mittra]

I took a leap of faith and bought a 2008 Yaris over the weekend. It certainly fills my fun quotient. My previous car was a 2002 VW Beetle Turbo Sport (1.8L). So far I'm impressed by the Yaris' tighter turning radius and peppy feel. I'm not missing the turbo just yet, but have this sense I likely will soon.

I'm a little frustrated that my manual transmission Yaris doesn't have a tach. From poking around and reading her a little, it appears this came in very few models. If I go dumpster diving at the local salvage yards, which other Yaris models came with a tach and is it a reasonably simple swap? I'm fairly mechanically inclined, but want to be sure there isn't a lot of specialized tools or knowledge needed.

I definitely get the impression this little car is not going to be a let down at all when it comes to fun. So what are the typical, immediate mods that veteran Yaris owners recommend doing?
