May I ask why did you go iridiun and also why did you go 8's?

I was just wondering because from every thing ive seen you are better of running normal plugs and replacing then every 10k or so due to the fact they have a better burn under high load and it works out cheaper

I chose them because they quickly transport away the heat (they stay cooler) and that reduce the knocking (spontaneous explosions). I have run 6 and 7 graded plugs and going up to 7 made a good improvement. The more power the colder plug.

An ultra-fine (0.6mm) center electrode reducing the voltage requirement for spark. This allows for a brighter, stronger spark from existing ignition system. The ground electrode has a tapered cut at the firing end which reduces quenching for better flame core growth and increased ignitability.

They are not too expensive. So changing them every one or two years is OK with me.

The extreme top fuel machines go as high as 9-10 with lots of exotic material on the tips. That suit their engines quite well but for a modest +700 hp machine like mine, it is enough with grade 8 and the "standard" Iridium IX.

This is how to change the wheel studs to longer ones (not my car on some pictures)

Remove the wheels

Remove the bolts on the backside of the brake caliper (socket 17) and hang it up with a bit of wire.

Remove the center cover on the wheel hub with a flat screwdriver.

Remove the lock pin (replace with a new one)

Use a pair of flat pliers, squeeze the legs together and press out the pin

Remove the centre nut (socket 32). The wheel hub will start rotating, use a long bar or equal between the floor and the wheel studs to hold the wheel hub in place.

When the nut is removed, take out the washer placed behind it and pull off the wheel hub

Press the old studs out. If you dont have a wise or equal, you can hammer them out.

Please try to avoid using to much force when smacking them out, every blow will make small dimples inside the bearings. If you use a small sledge hammer One firm blow is better than multiple smaller ones. Support from behind is good to save the bearings.

Place the new longer studs in correct position (splines). Carefully knock them in a bit. Important that the splines are correctly alligned. Use a larger socket and a wheel nut and tighten till the stud is firmly seated towards the back of the hub..

Clean all surfaces and put new grease on the bearing surfaces. If you plan to use larger brake discs in the future, it is a good idea to remove the splash guard behinf the brake disc before you remount the disc.

Remount the washer, nut and locking pin. Assemble brake disc and spacer.

Remount the brake caliper

Mount the wheels and enjoy the wider stance :)

This is the result on my car (no spacers mounted yet and Camber not adjusted). This is also before the wider fenders are mounted.

I use a 5-stud wheel hub with pin studs. Make life much easier

I do not want to mess around with lots of hard to reach screws and nuts so I looked around to find a good solution.

Thanks to Creatix I managed to lay my hands on a bunch of really good Stainless Steel V-band clamps and flanges. They make life so much easier eliminating the hassle with aligning bolted flanges. Easy to mount and dismantle.

I will use them on the exhaust system, the down pipe, the front pipe, the two wastegates and on the turbon :P

    • It turns out that Setrab make a fan specifically for the oil cooler which is great and I've installed it with minimal swearing. I removed my 2x 12in push fans from the front of my aircon condenser and wired them into this. My main thermo fans kick on when I use the aircon anyway and would effectively already be working as puller fans through the condensor which is infront of the rad. The push fans (understandably) didn't really do much in the config they were previously in so now they're out. Now we're on to the "Oil fan doesn't really do much either!". Yes I'll duct it next if it does nothing in heavy use which it shouldn't. But hey, the object exists and fits great and is cool. Let me have this. The car is still in the "do my fittings leak oil now? do my wheels actually rub?" phase. I did a spirited drive on them and didn't hear or feel anything. Then I got back home and noticed there were grind marks on the inside of the rims, though I couldn't see where they were touching I got out the grinder and attacked the suspects. Note: I do not know how to use a grinder. Then I realised I had dragged my new rims across my concrete driveway before I did this drive. I didn't think I had damage at that time when I briefly looked...... but remembered this occurred after I did all the angle grinding. The grinding on the wheels in some very specific spots. It's not around the whole rim for example, which lines up with dragging it across concrete more than hitting a suspension component for even 1 full rotation. So everything is currently painted and taped up and I need to test it some more to see if it really IS rubbing, but from inside the car it doesn't feel like it is. In other news I attempted to do a before and after comparison of the heads/cam upgrade thing. Dynos lie, everything is in different measurements. Here is the data from the sandown back straight. Car go faster than before. Vroom vroom.
    • Here's my base ignition. +3 correction to redline when shooting water/meth which is always on. Looking at my old ignition table, I should be able to add 1-2 degree's next time I'm on the dyno.  Let me know your thoughts. 
    • Given what I know now - same haha, but this was 12 years ago with second hand 740cc Nismo injectors in my S15 daily, I was too busy hunting elsewhere for the issue to even look at the injectors, running through some cleaner was a happy coincidence haha
    • Not a terrible idea. But if I ever had concerns that my injectors were sufficiently dirty to be causing me a problem, they would be out of the engine and onto the actual injector cleaner/testing bench.
    • Run some injector cleaner through it I had a similar issue that plagued me for months, even tried replacing the cat. If one or more injectors are blocked up the ecu sees ping so pulls timing and makes the tune rich overall, you'll see black smoke coming out of the exhaust and like me assume it's running rich but it could only be one or two cylinders  $10 bottle of injector cleaner and the next time I hit boost it pumped out a huge plume of black smoke, cleared the blockage and then ran great, if that's not the issue it's only a cheap thing to try haha
