HR30 PNE is hardly a shitter its like the brock edition of a commo (sorry to have to use that foul language).
I own a few cars of which one is powered by an RB25DET and the other a modified L28E.. guess which ones more fun to drive? thats right the MR30!! that L series growl and the unadulterated power is insane, who cares if its only a 2 valve, single cam, non cross flow engine? they can still make power and are a very good engine... and i am sure Ghostriders intentions for the 3.1L are not going to be shabby.
