Rikki 2 Posted July 21, 2010 Report Share Posted July 21, 2010 Rado wont fit obd2. You can port and polish it but you lose torque and dont really gain any! Link to post Share on other sites
FishWick 21 Posted July 21, 2010 Report Share Posted July 21, 2010 I wouldn't mess with OBD2 throttle bodies. They are £350 from VW if you mess it up! You can't enlarge the throttle plate either, which is where the gains come from. Polishing alone does nothing as the throttle hole is still the same size.OBD2 has servo motor idle control, so none of the OBD1 throttles will fit (different stud pattern) or work with the ECU.The head is the biggest restriction. Look at cams and bigger valves if you can afford it. There are no cheap tweaks for the VR sadly....If you can get a Corrado G60 gearbox for pennies and know a mate who can build transmissions, fit the G60's final drive to your VR box. Honestly, that alone makes more difference to accceleration than cams, throttles and breathing work put together. Link to post Share on other sites
