All I am thinking of installing a water /meth kit on my starlet - the motor is forged with CP pistons, Scat H-beam rods, Arp bolts, MSL head gasket, 370 cc Injectors. Running a Borgwarmer KKK 14 turbo, front maint intercooler and fuel pressure regulator. Any one done this before? Main reason for doing this is for the benefit of running higher boost and lower intake temperature. I also heard you an also increase timing with such system. Looking forward to your comments. Bertie
