DIS or not?

i have been looking at IS engine pics, and i don't see a distributor, like you do in supra 2jzge's. did the 2jzge motor go distributorless when toyota incorporated VVTI into it, or does the IS have a distributor that is hard to see in the pic i have.
i did notice something on the front of one of the cams, that could be a cam position sensor.

Well Dtew, or anyone that owns one....what's the verdict?
sweet, thanks i appreciate it, i guess it is very similar to the 2jzgte ignition setup. thanks again

dtew, are you sure about that? the 7mgte has only 3 coils, with a cam position sensor, but it also has a used spark and a waste spark for each cylinder. but i can guarantee it has 3 coils, 6 cylinders and DIS.
just to be clear, this isn't a challenge or flame, just a question, as i am trying to soak up as much about the IS, before i get my 5 speed.

LOL (DOH) thats cool. like i said, i know nothing about this car, and was just trying to verify. its really cool you have a service manual, how much did that run you?

IS300GTE: Referring back to the service manual, I'm not so certain anymore. There are three coil bodies that are connected to two plugs per. Diagnosing a faulty coil body consists of measuring two sets of resistances, the "primary coil resistance" and the "secondary coil resistance". Originally, I took that to mean that the coil body possessed both a primary coil and a secondary coil. Now that I'm scanning both the illustration and resistance values, I see that the two resistance measurements aren't parallel. And the ignition coil connector has only two prongs. These suggest that the three-coil/waste spark scenario is likely. Now looking through the diagnostics and circuit diagram book, I can confirm that there are only three coils. A cam position sensor feeds into the ECM, which feeds into an igniter, which feeds into the three coils.

Doh!

Scott is correct! 72lb/torque would have done alot better for that car. they should have had a recall on the fiber gaskets also, but oh well.

Actually, all it needed was to be torqued down more.

Hey Dtew, where is the cam position sensor located at anyways? tia
k, once i can get a hold of a car to get some pics, and look under the hood, i will check, thank you.
