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 This post has been edited by west_minist: May 18, 2003 - 9:00 PM |

Yes as I state to you. Once you are looking for serious power, you will lost it.
That is why I am having difficulty with you and others on low power. Check you the Supra and others. Yes. go for the cam gear from either HKS or Jun. I like them better than the toda. The cams will be the 3SGTE. It is up to you on the 264 or 272. If you are really planning to do some really head work, 272 maybe good. My mechanic have a 4age 20v w/ 264 that idle farily rough. THe stock ecu have problems with it. You have a aftermarket one, so it should not be a problem. Do you have aim? Please log on RC Engineering 550cc Injectors (enough head room over 240HP+[(actual 340hp+)] @ flywheel and for turbocharging later if you can. If not, use up to 420cc ) JUN GT Surge Tank (2015M-T001) JUN SPROCKET (1033M-T702) OR HKS Cam Gear (2204-RT001) JUN CAMSHAFT KIT (1033M-T005) JUN STROKER KIT (1029M-T003) (87.0x92.0mm) JUN Racing Valve Guide (1008M-T002) JUN ULTRA LIGHT WEIGHT Flywheel (2010M-T012) http://www.hksusa.com By phone: (310) 491 3300 - M thru F 8am-5pm PST By mail: HKS USA -13401 S.
