Thanks Bryan, that is a bit steep for just a sample part I think :) I guess I could use that for a starting point to build a ground up engine but I'd prefer not to build an engine part by part.
I just had a idea pop in my head and that is the guy in Calgary who is a rotor head [Rx7 specialty??] I'm pretty sure he would have a ruined housing or two.. whether I can deal w/ him or not I dunno.
The last time I contacted him he was wanting crazy prices for ruined parts [not scrap value for certain]. I'll have to call and see..
