So I've been looking for hours but can't seem to find an answer and I hope some of you guys might have experience with this. I was looking to get an aftermarket intake manifold for the Aristo VVTI 2JZGTE, but all the intake manifolds I found only fit the NON-VVti model, I also have the same problem with the fuel rail. So My question is... Will the lower intake manifold of the non-VVTi bolt up to the VVTi block?

The IM gasket is the same part number for both...so there's a good chance they can be interchanged.

Do you know if the exhaust manifolds are the same between the non-vvti and vvti engines?

Oh nice find! Where did you find the part number for the VVT-i model? Also are you referring to the gasket that bolts to the head or the gasket between the plenum and the runners?

I have a list of part numbers/diagrams for the JZS161.

I was referring to the gasket at the head. If needed, I can cross check the plenum to runners gasket as well.

Ya is looks like the runners should be interchangeable. The gasket on both sides are the same and the newest part number for the intake manifold runners looks like they're interchangeable with all year supras including vvti and non-vvti

And even the gaskets on both sides of the manifold are also the same.

the vvti intake and exhaust manifolds are the same for a non vvti gte.. the diff is the vvti gte has the same ports as the regular gte. so both manifolds are interchangeable. the vvti ge is whats different

yes it will fit and bolt right up

I have a very similar question:
I was wondering if I can use the 2JZ-GTE VVTi Intake Manifold on the 2JZ-GTE non-VVTi head.
Or second scenario:
Use a GE runner with the GTE VVTi plenum and TB on a GE-T setup (loving the FFIM setup).

Reason:
I want to retain my ECTS-i (cruise, traction, etc) because i believe the VVTi system has a built-in Traction Control instead of the extra control from the non-VVTi setup.

My ideal set up would be:

Non-VVTi 2JZ-GTE with the entire VVTi front facing intake manifold.

** Not a VVTi fan but love the FFIM from the VVTi setup **

I have a 99 GS300 (2JZ-GE VVTi)
Love the idea of a 2JZ-GE(T) setup with a FFIM (from a GTE VVTi setup) with the A650E 5-speed automatic.

The GE runner will not bolt on the GTE plenum

VVTI or NON-VVTI intake manifolds will bolt to either head. You can interchange them. They are laid out a little different for ports and sensors, but you can make it work.

The largest difference is that the NON-VVTI has the idle air valve mounted on it, where as the VVTI idle is controlled internally of the throttle body assembly. But either throttle body will mount on either manifold. So if u want to run the aristo ecu and VVTI t-body you can mount that onto the NON-VVTI intake manifold and use a blockoff plate over the hole for the idle air valve. Titan or MVP sells them.

Most of the aftermarket NON-VVTI manifolds have the iac valve on the bottom so you don't see it, so just block it off and attach your vvti t-body to the manifold a run with a gs300/piggy or aristo ecu. I assume this is the option your looking to do with the common 'greddy style' looking manifold?

The other small differences is the vsv's and check valves on the vvti manifold, one is for the fpr and one is for the evap venting. you can mount those hiiden under the manifold runners and connect the vac feeds to the new manifold and retain function, or you can ditch the evap vsv if you don't mind a little gas smell from the engine after parking sometimes.

For the fuel rail, a GTE top-feed aftermarket rail setup will fit the VVTI or NON-VVTI the same either way. And when you run a top feed rail and a external FPR you can ditch the vsv that was for the oem fpr on the old oem rail.

If you will be running a standalone ecu on the VVTI engine, you can use any throttle body like an accufab or Q45 and use the NON-VVTI idle air valve.
