Im putting a t25 on my 120y and have sorted pretty much everything out just one question.
Were should i plumb the crank case vent pipe which currently goes under the carb in the inlet manifold?
Its a draw thought setup with a single SU!
i was thinking of putting it after the SU but before the turbo, but i also thought this would let it see huge amounts of vacuum! Is this a problem!
Any help would be great!

Run it between carb and filter.
