Seeing how this kit/compressor/turbine makes and maxes out at 245-310rwhp (depending on tuning and running E85 or not), and will honestly never reach 350-400+ rwhp without major expensive changes (swapping in a larger more expensive compressor, fuel support mods, pulley, engine/block/head rebuild, etc.), I believe putting in a 4.56 FD will give it a bit more grunt and quickness…especially if you feel you still want “more” after the JRSC install.

JRSC + 4.56 FD ….your opinion?


I think this is what I would like to do (of course, dependent on this little thing, $6k)

Honestly, I feel like I run through the gears fast enough already. Don't need them shorter at all.
