1UZ ITB's Finally here?
1UZ ITB's Finally here?
Hello I've seen this brought up before but I found a seller on ebay that sells the OBX throttles.

Is it finally available or are they just selling hopes and dreams? Looks pretty awesome either way.

I don't think OBX offers this, but a scant few Australian companies offer ITB setups for this engine as they have more experience with 1UZ engines.

I'm surprised the performance market for the 1uz is so little. I mean sure you can find parts here and there but there's not enough competition to keep the prices reasonable. I like the 1uz but don't want to mod it because it's more to mod than a 2jz and the power output is next to none. Just thought it was cool to see ITB's on a 1uz.

Lots of 1uz's out there running ITBs. They are all race cars though, and by that I mean I can only think of maybe one or two cars at max that are street driven with ITB's. Its way to much engine management work for what little positive out come they give you

If you are feelin froggy and do want to go ITBs, you can always run an AEM EMS2 for a 2JZ on your 1UZ. The V2 has 8 injector and 8 ignition outputs on it, so you're able to run it on the 1U. Also, by running the AEM unit, you'll be able to eliminate the factory MAF, and just run a MAP and IAT.
I think ITB's on forced induction cars are somewhat pointless. Besides the 'cool' factor and increased throttle response, they probably don't add much power.
They are incredibly difficult to balance. If you have a carb synchronizer in your garage, then you can definitely do it but it's still not a fun job.
The gains on a properly set up N/A motor are pretty amazing. In the VQ35 world, we struggle to break 300RWHP even with cams and built motors. However, with ITB's a handful of guys have surpassed that barrier, even breaking the 370RWHP N/A mark.

nobody would run itbs with a turbo for extra power, but they really want more throttle response from running it like that.
these days it is much easier to sync each throttle body than before compared to carburetors as long as you have a linear way of opening them and connect all the vacuum lines together in a block or tube to syncronize the vacuum, it shouldnt be hard at all to tune the throttles to open evenly and perform correctly. i have set many up on 4 cylinders and some sbcs.
