i have a b18a and ive been debating on doing a LS/Vtec conversion with a pr3 head.. but now ive decided to go turbo.. am i better off building my engine or still doing a converstion?? and wut would be some good specs and parts list to push about 400 whp.. how much power can you get from a built ls ...

 

i think id be a little more resonable to look between 300 -350 is this possible with a ls and wut would in need ..
