i was reading tpr(tuner parts review) and they installed an electric water pump on their rwd sr20det even though the electric water pump is made for the fwd version, they just had to make a custom bracket and attach it to the suspension or something like that. either way they dyno’d the silvia with the electric water pump on it and actually got hp and torque gains about 7-10 hp and about 5 torque, with a water pump you say. that’s pretty cool. :lol:
