i had my vf34 running at 20 psi felt like max pressure for turbo after a year it didnt sound like new at all anymore, 1400 is good price up pipe aswell? 1400 is the high end price can get just turbo cheaper. i had all the mods 880cc jets 500hp feul pump top notch front mount custom made APEXI comp made 260 and 360nm on a solid deck 94 motor get the p20 rear housing the p18 u can feel it die at the end of ur revs, its annoying. if the ecu plugs in shouild be fine but if ur doin upgrades spend the 1k get an apexi and hand controller, great gains and u can monitor everything from digial readings if u mount it behind ur steering wheel. looks flash too
