The next mod I did was to install a Perrin Crank Pulley - Black.
Here's a video of the first start up after installation. Check the video page for more.
My next purchase was a Grimmspeed Oil Cap. I got into the group buy early and was #12 on the list. I also bought their battery tie down as well. I didn't install that yet because my car has been parked for the winter and my garage is not heated.
One of my next projects is going to be the stereo system. I have my wiring harness, mounting kit, and antennae adapter already. You can find the parts here from Scosche: 10% off ALL items on Scosche.com until the end of February - use promo code: sco10
