had my astra gsi rolling roaded today but it only made 270bhp on the rollers. the operator told me the torque was making the clutch slip so i`v gotta get a better one.
however the syncro on 3rd on my gearbox has gone (crunching when under hard acceleration) so i might as well do that while its off.
only prob is there seems to be 100 diff types of the f23 box.
i know the 2.2 vectra boxes don`t fit due to the starter motor, but anyone know about the 2.0 dti f23 boxes etc?. . . . . . .
