VVT-i?? Cams upgrade, VVT-i + Cams Options

[west_minist]

Hi all!

I think that I have mess up.

My Mechanic have a Gen 1 4AGE 20v Silver top with upgraded 264 cams with VVT

He stated to me that he still have vvt. VVT is in this case is either on or off. VVT-i is variable VVT.

Now if what he stated to me is true(which I do not have any doubt), that means that you may not lose vvt-i if you have upgrade your cams Maikl!

His cams was purchase for the 20v. I do not know if there are from Todaracing or TRD, by there cam from Miami.

I will try and see how the VVT setup works in this case tomorrow.

Just did some research, and it may seem right now that toda offer cams for VVT system.

In fact, with further research, VVT and VVT-i is in the VVT controller. But here is where the problem can arise.

Qoute from Bill Sherwood (http://www.billzilla.org/vvtvtec.htm):-

"The early VVT system was relatively simple, ie, at a specific rpm (~4400rpm on the 20 valve 4AGE's) the computer signals the OCV to open, this lets oil pressure go through a special gallery in the #1 inlet cam bearing, through the centre of the inlet cam to the VVT pulley. There's a small piston in the VVT pulley, and once it gets enough pressure behind it, it starts to move outwards, causing the outer part of the pulley to turn in relation to the inner part, due to the helical spline that guides the piston's fore & aft movement."

So if you purchase a cam not design for vvt, good bye vvt, but if you buy a cam enable vvt, you are in luck

So Maikl, there may be some hope for you.

Looking at todaracing, you can get cams with vvt.

My mistake was that once you go to a big cam, you would want to dial in the HP and torque for you driving habits or where there just occurs at their max. If you use a Cam Gear, you will lose vvt, vvt-i.

So maikl, http://www.todaracing.com/products/toyota/..._3sg_specs.html

264 would be good for you. Idle a little rough

Ok. I have been stress out the last couple of weeks at work.

He is right. I am very sorry.

(Unconsciously, I knew the statement below would work when I told you so. I had always knew and did not think twice when I lose my VVT-i upgrading to bigger cams)

You can use the 3SGTE Cams since the 3SGE gen 4 head is the same in the cam profile as the 3 gen 3SGTE.

Even it you lose the vvt-i, it is ok since you will be running big cams to over come that effect.

I will contact toda racing on your behalf and post the email here. Is that alright?

You see, at the end of the day, you are modding to the 3SGTE specs.

There is no strenght differents in the blocks of the 3rd gen 3SGTE and the 4 Gen 3SGE.

Did you check out that site.

In the usa, there are really specialise there. Toda racing is a Japanese company.

There make racing parts for all the well know cars.

Alot of 3SGTE builds ups come from the 3SGE which is contrary to manu USAer believes.

It is may be easier to get the a 3SGTE block, but it can be started from the 3SGE block, install some oil coilers in the head (maybe present in the latest gen 3SGE, 11.5:1) since the 4AGE 20v have them.)
