if u set ur car up right understeer wont be a problem with a turbo.
in saying that im an biased towards a b20 set up and a turbo set up, as i have a B20 Turbo.
both will give good low end torque to pull u out of the corners and if u have the right equipment in the car it can be a great set up.
both can be had at reasonable prices these days.
