BOTH A STOCK LS1.....same motor, 346cid! a SS, WS6 is tunned more, plus ram air, and a few little things differnet they put out 325....so i don't know if that makes any point, i was just backing up what he said!

i agree what your saying about detuned engines, thats the way the 2jz-gte (supra TT engine) and the rb26dett(skyline gtr engine) come. they lower boost and restrict airfow alot to lower insurance and to keep japans gentalmans agreement of 280ps.
