rb20det - drawbacks

[matress]

hi guys,

just been speaking to a mate about the rb20det motors, he's saying something about the standard ceramic turbo not coping with much more than 12 psi and the motors not having much potential to make big power.

what is the biggest turbine a/r you could go on one of these, i've got a series 4 rx7 turbo at home (0.86 a/r) and im wondering if that would work or be too laggy.

i like r32 skylines a lot more than r33's but im more concerned about the potential of the car to go faster.
