No major performance benefit, are you crazy? A 2v only puts down like 260ish to the wheels with full boltons and a tune..3v's put down like 310-315whp with full boltons...At like 260ish-270whp stock....Not to mention the gain when u boost it..2v are terrible..The heads suck...My car will be way faster with the swap. All is needed is the conversion kit from logan motorsports, adjustable cam gears, and a couple other things...To who said u could take the money im spending on the 3v and make my 2v faster??????IDK what your goals are but mine must be different..Im only gonna have about 3,000 in the swap.
