sleepyVR 0 Posted October 12, 2008 Report Share Posted October 12, 2008 Could someone please explain the differences between the 2. I know that the 2.9 lump had an extra 10 bhp. Also what mechanically parts are different? Link to post Share on other sites
CorradoVR6-n.o.s 0 Posted October 12, 2008 Report Share Posted October 12, 2008 inlet and throttle body are smaller on the 2.8 and the bore size.The later 2.8 are obd2 and have the same power as the 2.9's due to the more advance managment. Link to post Share on other sites
