Aftermarket Intake on n/a-t Question?
 

Hi, I am sorry if this is answered somewhere, but I've had a good search and can't see it, so here goes.

I have a 95 supra Na-t and I am looking at changing the intake and throttle body to the tt style aftermarket one, however I have noticed that the standard throttle body has 2 sensors (Throttle position sensor and Idle control I believe) and the aftermarket throttle bodies all seem to have a fitting for only 1 sensor (the TPS). I was wondering has anyone done this mod or knows how to overcome the problem?

I am not too clever with the inner workings of engines so maybe the idle control is bypassed/ replaced or something??

Thank you in advance for any help,

Jason

On a 2jz-gTe, the second sensor on the 2jz-gte throttle body is for the secondary throttle plate...which is assocated with the oem traction control system. There are kits available to remove the secondary throttle plate and the entire traction control system, since it is somewhat unsophisticated in its operation. Many prefer to drive without it or replace it with something more feature-rich like RaceLogic. You could use one of the trac-elimination kits to remove the secondary throttle plate and there would be no need for the secondary TPS.

Just to confirm, its a GE, not a GTE, are they the same? A mechanic told me it was an idle control valve, and when he disconnected it the car started revving up and down on its own.

This is a picture i borrowed, it the sensor on the left nearest the dizzy.

No, they're not the same.

The throttle body in your picture is not from a 2jz-gTe.

Yes, perhaps there is a misunderstanding, I have a Na-t 2jz-ge not a gte and I want to fit the tt style aftermarket intake for the GE, With the 90 mm throttle body but the sensor? I dont know what to do with it? when disconnected car revs up and down uncontrollably.

Where did you get the 90mm throttle body? Neither the 2jz-gTe nor the 2jz-ge have a 90mm throttle body...

The erratic revving may be a problem with your IAC valve/motor or a vacuum leak...
