[VADER SS L99]

The cost per dollar ratio of the FI route far outways the motor swap. Lets say you do get 620fwhp on the LSX. The FI route could be making that much to the wheels and have alot of extra money to pocket. Those that say the LSX would be a drag only engine with alot of maintenance are wrong though. This motor could be made to have perfect driveability with the same maintenance of the ls3. The only thing that would suffer is mpg, by alot. lol. If you have some problem with FI then the LSX motor combination is a good choice or if you are going for more than 800rwhp. If you are not going for insane power and have no discrimination to FI than this motor route is just more money than you need to spend.
