im plannin on supercharging my jdm b20 im only gonna run about 6psi on stock internals but my question is what else i should upgrade fuel system etc......

 

I would suggest a good engine management (hondata,chrome,neptune), some bigger injectors (you could do 370's or 440's) and a bigger fuel pump (255lph). You may also get some power from adj cam gears. If the motor is getting torn down I would suggest arp rod bolts and head studs.
