from the FAQ:

"Does Shell plan to put ethanol in any of its other fuel products?

Following the success of Shell Optimax Extreme and in support of the Federal Governments commitment to biofuels targets, our intention at this stage is to expand our use of ethanol. But, as there are some vehicles that are unable to use fuel containing ethanol, Shell does not plan to put ethanol in all petrol products"

Thoughts?

it contains 5% ethanol, so i'd be re-tuning your cars ASAP!!! there are no hard facts about this fuel yet, (regarding to how it affects your motor). we all know that it will run leaner, but exactly how much??? i would be very careful indeed.......

My GTR is in the shop now getting tuned for Boost98 (10% ethanol) as Extreme is not available in enough places to warrant switching to it.

I wont be able to give a direct comparison with normal 98octane as I am having other work done as well,only feedback from my tuner in regards to timing and fuel maps.

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
