Potential Donor...could use opinions!

[crashprone]

Hi All, Long time lurking and watching build threads. I've been getting ready for a kit car for a long time and I think it's about time to pull the trigger. The 818 being the gorgeous machine that it is has had me watching out on occasion for WRXs. I just saw this one:

I'm taking a look at it tonight, but any advice would be handy. I've been into cars a long time, but I'm pretty new to WRX's specifically. Main appeal to me is a basically new crate short block!

Thanks much for opinions and/or suggestions on things to look for and ask!
