Non Linear Throttle Bodies/cammed Throttles For Rb25Det

[zoomzoom]

Has anybody fitted different throttle body pulley wheels to give a more logarithmic response to throttle? eg the first 40-50% of accelerator pedal travel results in 20% throttle opening, at a rough estimate.

GKtech has that sort of an item for SR's, if NS was a half decent forum you might get some info on it there (but its not).

I built a TD05H DE+T for a mate which is a little too trigger happy in the hills, so i was planning to pick up one of these to resolve the issue. So its a little less sensitive when trying to ease on the throttle. Im not sure how it will actually work out as I fear hitting the 50% point will be the next obstacle.

I hope that helps.

Yeah thanks, Ill give one a shot. It looks like it might fit an rb25det throttle body.

What ECU do you have, we use the Vipec to map boost vs throttle position.

Just the standard ECU. I dont mind controlling the boost with my right foot, Ill see if the new pulley can be fitted. Theres other things like the extremely sensitive lockup clutch on the torque converter which unlocks at low throttle. Even going over a bump in the road will move my foot enough.

Update:

These things also fit an RB25DET. I needed to make a new throttle cable holder (the part that bolts onto the top of the intake manifold), and add a few washers to space the pulley properly on the throttle body, but its a straightforward replacement otherwise, and performs just the way I wanted it to.
