Just got and RA turbo upgraded and plan on installing in spring. Already have tune, boost pill, HFC , Evo X bpv, evo X intercooler and piping. Currently 250whp/292wtq...Figured while I'm slapping the new one on may as well upgrade the WGA. Are the Evo X ones direct bolt on to the RA turbo?

Found this any suggestions on which spring would be best for a DD driven a lot in traffic?

Along with turbo will be adding 850cc injectors, dw65c fuel pump, 3 port ebcs, motor mounts, cat back and re-tune.
