what do you mean by 'adjustable cams'?

you can't get adjustable cam gears as it interferes with VVTi

If you are talking about adjusting the cam timing, this can be done many ways with different ECUs, piggybacks and plug in controllers.

no they are saying that you can't get an adjustable cam gear because of the vvti. However, if you wish to change the cam timing (different to adjusting the cam gear) you can with a cam controller, but it would be pretty pointless

If you fit a vvti controller you will still need something that can control the fuel.

i believe that the power enterprise cam controller can do air fuel settingg in it .. is dat what u talking about ?

Or you can change the physical camshaft piece for a different brand with a more aggressive profile

changing physical cam shaft meaning what ... changing the size or length ?

Neither. The cam determines such things as when the valves open and for how long. Standard cams will be for fuel economy. Performance companies make gnarly cams that will open a particular valve for longer at the right time, for example, which would make your car marginally quicker. Watch the VVTLi annimation pinned by Northy in the technical section, it's related sort of. If you change the actual camshaft you won't need any electrical crap, it's good old fashioned muslce car technology.

Changing to a more aggressive cam profile/design. Aggressive cams tend to have more valve lift, duration and overlap which moves the power band higher in the rev range. Cams can however also be chosen to target more mid range or low end depending on what you want out of the engine. There is a lot of detail in cam design and selection and this probably isn't the time or place to discuss it, but this should give a good overview on what cams do and help you decide what you're ultimately after, Wikipedia link and How Stuff Works link.

Crower offer aftermarket cam shafts for the 1zz.

yeah I know....I have it :)

but the airfuel ratio isn't simple to set.

you need a wideband to check the correct ratio.

Guys tell me a brand that produces a camshaft piece for my engine (3zz-fe - european) :help:

I have never looked before, but you might have to go with a custom grind. I'm sure there are some specialists that can do regrinds or new billet grinds near you.

      Toyota Landcruiser problems

      Hi This is not so much to the forum but to Toyota who i cannot contact!! Purchased new 300 Landcruiser ($120k) & generally happy with the drive but frustrated with fixing problems. bonnet need restuffing took me 5 Toyota dealerships & a lot time i cannot afford for a 3 day job afer it had been booked into Heidelberg & on collection did not perform the stuffing to stock it shaking & reflecting strong sun light into drivers eyes when vehicle was clean. when i collected vehicle from overnight service (2 days) after 2nd visit with some booking confusion they told me they need vehicle for 3 days just prior to me driving from Melbourne to Flinders rangers SA again very costly in time to me because a bolt had fallen out of turbo charger (20k klm). i have had a list if issues none of the 5 Toyota dealerships visited can resolve: no guests can close the rear hatch because you need to slam it & most do not have the strength even if they new what to do - seal has been replaced. i have never been able to understand logic of why no rear hatch release was included in vehicle, 1st vehicle i have owned without boot release? no location for key apart from centre console where key is lost amongst so many items unable to reverse any trailer, boat or horse float as vehicle brakes & locks up which is dangerous to horses being thrown & reversing into drive with traffic on a busy road - every possible idea has been suggested again very expensive on my time but no one can resolve! Unable to get google maps or music without plugging cord into phone - very aged technology but safari same vehicle does not need cord!! do not understand this logic other than justifying another $20k Radio or music must be reloaded after each phone call or restarting vehicle - some 6-8 buttons to reload music - very frustrating. AM 3AW is muffled & very poor quality (not my hearing). Alarm of beeping drivers door cannot be turned off - i do not need vehicle to alarm warning me of drivers door open as i am the one who purposely have left door open - very frustrating & no need for alarm beeping, cannot turn this off!! Ordered dark interior but got light interior ?? which i accepted on the condition the carpet was not light beige, guess what it was. Why would a country farm 4 wheel drive have white carpet? Toyota what are you thinking? i have a black cattle working dog so my rear interior is trashed & the fabric entraps dog hair unlike a good quality wool carpet, poor quality synthetic which is not serviceable like previous BMW quality. i would love Toyota direct (not dealerships / agents who are not trained) to help me resolve direct. Direct contact with Toyota not possible, customer service from dealerships disappointing based on cost of vehicle, i believe i am a very reasonable person.

      Fuel Filter - Change or not

      This is the conundrum: 200 series Landcruiser diesel. As the fuel filter get dirtier, in theory it is filtering more as it is becoming somewhat restrictive. As long as the fuel pressure remains the same on the other side, should you change the filter. I know of owners who change their fuel each time they change engine oil. This is not the same as an air filter which as it get dirty it restrict the air flow. Or do you simply change the filter because it's 'the right thing to do'?
