1UZFE ITB's Vacuum tank?

**driftae76** · 05-07-2011, 05:40 PM

Hey Im fitting some silvertop 4age ITB's on my 1uz and using Link G4 ECU for management.
Just want to know what people have done for vacuum tanks.. I want to run the original 1UZ ISC valve (controlled by the ecu).
I think its going to have to be a cube shape tank so that the ISC valve will feed all cylinders equally, not a long tube with the runners feeding into it like some ive seen..
Anyway please post your thoughts and pics etc please and any advice as to what works and what dosent.
Thanks

Im waiting for the ITB's to arrive from the USA, they are the OBX ones as seen on ebay, Im pretty sure they are just copies of the A1Turbos ones made in NZ which incorporate 20V 4AGE TB's
Anyrate I shall upload a pic once I have installed them, until then.. im sure some people here have put ITB's on 1UZFE's what did you do for idle control guys?

Check out Ed's 1UZ Supra on Toyota 1UZ-FE & 2UZ-FE V8 Technical and Performance Forums under the members rides area. He ran a vacuum tank in the valley that was fed from each ITB, and this had some kind of idle control system connected.
