Well, I followed the thread long enough and they are back on eBay. Looks like I have some work to do beginning of March. Thank you all for the info, part numbers and experiences!
Lucky guy, I've been doing the same since 90, I like to fiddle with things and crank up the boost. Had a couple meltdowns but the joy in between was unmatched.
Turbo's love to breathe! I built turbo cars back oh, 15yrs ago? The stock exhaust was always the first thing to go. And a turbo 4cyl, does not sound anything like an NA 4cyl. I dyno'ed many a car before and after and never had a loss of power.
I go to pick up this fella tomorrow. I've been trolling around for about 6 months looking for one that caught my eye and this one checks most of my boxes. Exciting times!
