GM has on several occasions put the "new" engine in the old body style vette a year or two before the new body style came out... Maybe they will do it again?Back to the topic (sorry i got off course). It seems to me that 2010 would be the first possible opportunity for anything to launch with a DI V8. And you can bet that the Corvette or a Caddy would be the first to get it. And if it ends up being the C7 Vette to get it first, then that is quite a ways off.
Hi BtB,Anyways, getting to my point, my honest opinion is that there wont be a Z28 SC model like some people are hoping - at least not for the first 3yrs. Who knows, I could be proven wrong though. I know one thing for sure, and that is the fact that I wont be sitting around waiting for such a model.
putting direct injection into a head with the valves side by side rather than opposing each other (well opposing two by two since the 3.6 is four valve) may not be possible. getting a di engine to run and operate smoothly is no easy feat. di has been around for many years and was unable to be used in passenger cars in this country due to poor driveability and high emmissions out the tailpipe...the fuel management advances in the software is a big part of why you see di engines now. gm was also trying to utilize vvt on a cam in block (ohv) engine but without the multiiple cams,the advantages were nil.
i don't think you will see di on the pushrod engines...
