fangsport, how well do 2t-b's go with high compression?
Just got a engineless te71 and thinking of putting one in to get it running while i build my 4age

really well. the 2-tb has a higher compression ratio than the 2tc and 3tc, so when you fit a 60thou head onto it , it gets bumped up even further. kept the 4ag powered cars honest for a season.
