ok, so i already have all the supporting mods that i need sitting in my garage. i now need to decide what turbo to put on. heres the engine mods that i have, the car is a 02 wrx with short ram intake, perrin fmic, perrin fuel rails. upipe, turbo back exhaust, sti injectors, mrt electronic boost control, 3 defi bf guages,utec, pwr radiator, exedy clutch and flywheel, and more that i cant think of right now. ive read many posts about people trying to decide on turbos and i concluded that i think i wanna go with the pe1818. i dont want to go with the 1820 because that might be a little rough on my stock internals and i want the car to run for a while. so if anybody out there is running the 1818 how is it, and howare the spool charicteristics? also will i neeed to get rid of the sti injetors and go with some a little bigger? if you think i should go a different route on the turbo please post your suggestions. any help would be greatly appreciated, thanks
