Hi all,

I'm going to be putting new spark plus and wires in my '98 Corolla Seca (AE101, 1.6lr, 4A-FE)in a couple of days and was just wanting to know what the correct spark plug gap should be?

They're NGK Iridium plugs (BKR5EIX-11). On the NGK site it states 1.1mm, which I'm assuming is just how they are gapped out of the box. I have a Haynes manual and it states 1.09mm. I read somewhere on another forum someone said it's supposed to be .032inches (.81mm).

I'm a little confused as to what gap I should be setting.

Any help would be greatly appreciated. Thanks :)

4AFE plugs run a 1.1mm gap. 7AFE plugs (aka for the AE102) run 0.8mm. This is probably where the confusion comes from.

Ah, ok. No gapping needed then. Thanks for the info. I appreciate it :)

In saying that though, my Gregorys manual doesn't differentiate between 4A and 7A and just lists 0.8mm.

      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.

      Disconnecting winch, lightbar and UHF

      Generally, yes. In the 60s, and earlier, there were cars with positive grounds, so I'm always a bit hesitant to say the negative wire. It is always the one that bolts to the body. Herb
