For some reason I can't get this link to work, but the web add is there, scroll to mini projects and go to "240SR", this website provides a complete guide on hwo to install an SR20, and has part #s' and other things you need to do, precautions and measures, and so much more info, I go to get some of my info from here, I know there is info on this in the FAQ and most of you are familiar with this site, but I thought it might help the newbies and anyone who wants a step by step guide. Has little shortcuts to do this too.
Hope it is of use to anyone.................................
