akeizm Posted November 16, 2003 Share Posted November 16, 2003 the big question...does it go hard? Quote Link to comment Share on other sites More sharing options...
Guest plainswolf Posted November 16, 2003 Share Posted November 16, 2003 I'd still rather have a good old proven pushrod V8... the superior torque factor. Quote Link to comment Share on other sites More sharing options...
Guest plainswolf Posted November 16, 2003 Share Posted November 16, 2003 But it has to be lighter than the datsun L engines.. and the power figures sure look darn good! Quote Link to comment Share on other sites More sharing options...
cameraobsess Posted November 16, 2003 Share Posted November 16, 2003 i dont know, seams like a really good engine but it has way tomany electrical parts. they made it more complicated than it really needs to be. the electric throtle control is what did it for me. just my two cents.

Guest NorCalZ Posted November 16, 2003 Share Posted November 16, 2003 there is already a thread on this engine. Supposedly offroader racers have been using this thing and are pushing really good numbers like 800+ HP. Look for the thread there are some good facts about this.
