Got some Denso iridiums atm along with Nology hotwires and powercore. Slight improvement in torque it seems. N/a cars usually don't gain too much from ignition upgrades :(

you dont have plug wires on a 1ZZ. Have a look in the engine bay. From memory you have denso platinum plugs in from factory, I like to change the platinums ever 50,000 instead of every 100,000 as recommended by Toyota.

ZZE corollas dont use Ignition/spark plug leads, they have "Coil on Plug" ie. each spark plug has its own ignition coil built into the spark plug cap... so unless you are going to change your whole ignition system and convert to coilpacks there is no point buying ignition leads unless you want to hang them from your rear veiw mirror or something ;)...

Basically all you can really do for the ZZE's is to replace the spark plugs... do a search for iridum plugs, i think Danz did a comparison a while back between a few diff plug types...

Edit: Beaten to it.... damn my slow typing :P

I have Iridium IX's on mine, didn't notice anything change, possibly ran a little smoother, but I could have been telling myself that as well to justify it.

I am using TRD Iridium, yeah yeah could be just branding, but it really is smoother than standard. Serious.

But if I am allowed to be honest here, Bosch Super 4 definitely gives GREATER respond. How great? Well the only best way I could really say it is that as if the car is lighter.

But later on, somewhere down the track, I heard Bosch Super 4 is not good for high compression engine. Don't ask to define what is high compression engine. Maybe 13.1:1 ehehehehe.

Hell, I don't even know if there is Bosch Super 4 for 1zz-fe, as I just took my friend's Bosch Super 4 from his Civic VTi-R and try it. Hehe. He didn't want to give it to me, so sadly I have to return it back after I tried it.

Well worth trying though.

      Android auto

      OK. Does any of Toyota's advertising material mention Android Auto? If so then kick up a stink, with Toyota management, about misrepresentation and false advertising, reminding them of the hefty fines. Herb

      1999 Camry Driver's door locking hatch issue

      It's possible that it could be something fouling or dirt build up, dry, or a broken mechanism, so have a look and give the mechanism some lubrication, most likely though, it'll be the actuator. I found one for a good price on Ebay, $25 delivered: Front Door Lock Actuator Right Side For Toyota Camry 1997-2001 | eBay

      Query about the correct rotors for 2006 ACV40 Camry.

      Hi, I'm looking at a set of front rotors for an ACV40 2006, 2.4L Camry. I got a good price on some RDA's at Sparesbox. However both RDA8112 and RDA7686 show as for my car and I'm wondering what the difference is and if there were changes to the rotors during the model production. So does anyone know which rotor is the correct one? Many thanks in advance.

      It's a simple solution though? Already laying down 60k for a RAV4, so what's another 1k on a phone to make everything work seamlessly? 👍

      Your solution is akin to suggesting that switching to a different car manufacturer would resolve the issue. However, not everyone shares the same enthusiasm for using an iPhone as you do.

      Turboed Corolla Overbuilt?

      that engine will be fine, the rods are the main thing to be concerned about. The 2860 is a decent turbo for the 1zz but in this day and age I'd go for a G25-550. The injectors might be on the small side, we run DW1000's. You need a full length injector, the shorter injectors with adaptors like ID1050x dont fit the 1zz head. You don't need an aftermarket intake manifold, if you do go down that path, avoid the CNC innovations unit, it's garbage. Do the boost control with a MAC valve and control it with the aftermarket ECU of your choice, I use Link stuff on most of my builds with the G4x Storm as the minimum. I also wire a fuel pressure sensor and oil pressure sensor to the ECU in my installs. Use a decent intercooler, the better cores (ARE, PWR, Garrett, Vibrant, Plazmaman, Hypertune) work a lot better than the chinese stuff like Aeroflow. a 450x250-300 fits fairly well with custom end tanks to route the cooler pipes through next to the radiator Don't forget about the clutch and gearbox. These days I like the Uniclutch twinplate, Above 300whp you'll want to think about upgrading the 3rd and 4th gears in the box also with the SSC (Hollinger) gear set and install an LSD of your choice. If you're going to give it a hard time, you'll also want an oil cooler. I like the HKS thermostat type sandwich plates and setrab or mocal oil coolers with -10 speedflow fittings/lines (Chinese AN fittings neck down to a lot smaller internal diameter in their bends, not great for flow) You'll also want to think about brakes, Celica or Sportivo front calipers will bolt on with sportivo discs as a starting point. To have somewhere like Tunehouse do the work you'll want to budget somewhere between 20-40K

      Camry Touring 2010 Fuel consumption 15.2L/100km. Normal?

      I did the mathematics myself regarding costs vs benefits for fuel injector cleaner. I have changed from 91ULP to 95PULP and 98PULP. Price difference can be about 13 -20 cents. Compared to 91ULP, Premium quality fuel should have a better quality additive package designed to have superior engine cleaning capabilities so the engine can perform at their best.

      "Fuel injector cleaner is a waste of money" Only if you by the cheap crap if you use LiquMolly a German Product it does work and you won't waste your Money.
