I now have a 4jj1 that I'm modifying, so will see how that project works out.
As for my 4jh1 mods, I have a custom ecu remap done (superchip nz) full 3" exhaust with hybrid subaru turbo running 18psi, I also had a chip from ecu chips so I could wind up the vp44 pump a little more and last installed a water/methanol injection system, which is the big jump in power you can see on the dyno print out.
