Fitting ITBs to the E30 325i but the E30 brake booster gets to close and wont allow a air box to be made...
Been thinking of a few options to solve this.
1... Golf or Clio booster, any other suggestions?
2... E28 hydraulic booster.. Seem like the best option as its not vacuum assist and actually runs off a powers steering pump. Only problem is this booster only comes on a M30 motor which runs a different power steering pump maybe to suit the hydraulic booster. Not sure it will work with the M20 pump.
Can anyone suggest anything else?
The old e36 M3 that were based on the M50 motors had ITBs that pushed strait out of the inlet and didnt curve up... They must of had the same issues fitting these motors to the E30s..
How did they do it?
