Pardon me for not reading all 6 pages but what are your plans? Have you been to cd5tuner.com? It's a little slow and iffy at times but there's a good amount of info and good people there.
This is a daily, so plans are accordingly. Coils and maybe wheels are in the picture, aside from that, not much more at this time.
That's a Russian Flag valve cover
I've been to CD5Tuner, don't have time to live on there though. I may get more into it one of these days, but right now I got too much other stuff going on.
