Hi All,
This probably qualifies as my first real "performance" upgrade. Lots of minor maintenance fixes with newer stuff etc., but this should net me a few HPs as well. Everything is new except for the 85/86 manifolds. We sand blasted and painted those.

So needless to say, I am excited to see how it turns out. There are not a whole lot of options for 16v engines other than a new SC. I do not feel like I want to go that route really right now anyway. I really like the way it is performing now, so this last piece should make it really fun to drive. After this I need to get the new upholstery in and think about when I want to paint it.

I am putting a link to my friend's Web site on 911's and 928's (mine) where he has a blog he is doing just for this job, step by step, with pictures. We have full permission to link to his site and blog, no problem. After his tussle with the new manifolds today, he said he wants to help anyone trying to do this, to help them on a few of the PITA parts. He does the jobs I do not want to tackle or have the expertise or tools for, and in this case, also can weld and do some fabrication and sand blasting. We are also putting on a new Y-pipe (custom, w/ added 2 inch section because of the new manifolds - Thanks Roger!) and new hi-perf cat.

I should have it back by Tuesday, and I am leaving for SITM on Friday...just in time! Should be awesome.
