the 'ramped up' version is the ls9. it is supercharged and from my reading they did this since the ls7 could not hold boost from thin cylinder walls. they are going to put a 'detuned' version of the ls9 in the cts-v but its touting a different engine code. however the ls2 does hold boost very well, it isnt a slouch.Originally Posted by 1.8t
atk: my buddy has the l92 heads on his ls2 and that car makes some power. i think a lil v6 mustang was talking **** to him for making noise but that noise is on purpose. we are taking a different path on collins ls2, should be done whenever redstar gets the parts back in house![]()
