2js do use vvti.

But you keep talking about the ECU learning. That is easily bypassed, so it is not a factor. You cant use that as a reason, except for when talking about a CAM only swap like hondas do.
The tC has a stong ECU so any major work also includes EMS. Same goes with the cam. So learning, which is your main argument, is not an issue.
This is the degree of my knowledge but, you seam to ignore it.

k one more time.. ill put it in this theory.. if the cam is bigger and the ecu reads more a/f being mixed.. it will nasturally adv/retard the timing to decrease that to make sure you are running at an economoy and perf. level.. but the thing to that is that no matter what our head runs on timing and not lift. thats the way it was designed.. no matter the lift the ecu will always fight it.. granted even with ems the lift will not be the factor but the actual timing is key. i think thats the part you might be missing.

I must be missing something.

Well I understand where both of you are coming from in this debate, but cams and timing will always add power to an engine if you know what you are doing when tuning it.

But I want to install them before I get a tuner for the car so
WHERE CAN I GET SOME N/A CAMS?!?

Oh and by the way the 2jz-gte never had VVTi on it in the Supra, only the newer 2jz-ge (non-turbo) engines in Lexus had the VVTi.

That is a swap car and not U.S.
Supra was only imported till 1998 in the US and the VVTi was never used on it.
The web page you have is a 2jz-gte bottem end with a 2jz-ge (VVTi) head and turbo.
The guy traded a turbo car for a non-turbo car and then turboed it.

There are no cams out there right now. You'll have to settle for custom regrinds.

Anyways, a question to TCpete: are you saying that even with an EMS controlling timing, the ECU would still somehow overcome it? I don't see how the ECU would be a problem if the EMS is sending modified information to the ECU to get it to react the way we want it to.

That's the part tcpete is missing.... He's absolutely right when it comes to closed loop controllers. Everything changes when using an open loop controller like the Eman U.

Like Ripp has said, Vortech superchargers really benefit from additional lift on the exhaust side. Show me a 311whp supercharged setup that does it with everything i've done but minus the cams, and maybe i'll believe it. I won't claim to be the expert on all things tuning.

But until then, it's all just talk
