Hey, just changed the spark plugs on my r33 gtst with some NGK BCPR7ES ($4.20 from repco) as suggest in another thread, and when I did this the old plugs I found in there were some HKS ones. Checked this out on the net and they are Iridium ones and cost about $20 us.

With the new $4.20 plugs in the car drove better. Just wondering if these would perform better if I got some new HKS ones? Also where would I get these from I cant find anywhere on the net to order them (only us sites)???

Also wondering where I can order from an australia website performance parts like this and others? Have ordered stuff from www.modyourcar.com.au and they were good.

Cheers

yeah its aust. I ordered some stuff put the money in their account and got the stuff in 2 days. I also was looking for where they were located so I could estimate how long it would take but couldnt find anything.

Anyone know of any other places you can get performance parts?

croat,

1.1mm should be fine if your boost is the factory 7psi. If you go and up the boost you might find the spark character better at a gap of 0.8mm. Do NGK know if your going to boost your car over the factory level? --- No. Do they care? --- No.

there ara few cheap ($3.99) options if you dont want to pay for greddy plugs or hks ones, i used champion racing plugs c61 equiv to 8 in ngk for the melb drift event, but also avail c59, c59 being slightly colder equiv to about 8.5 in a ngk good for cars running some decent boost. another option is bkr7evx gapped to around 7mm these are used in many of the drag skylines as they give good life.

honestly though while i piss fart around changing plugs for different runs and so on. the greddy plugs in the D1*garage s14.5 which are an 8, last the longest ive seen (30k+) and lost no power even with continued drift abuse constantly on the limiter at 1.2bar+ the things have been checked but still havent been changed.

Hey guys... just read this thread and noticed a few "questions" I can help answer.

ModYourCar is a complete online service, there is no shopfront. There are many reasons for this.

When yuo buy something it is usually shipped to you directly from one of our suppliers located all over Australia.

Most items ship relatively quick but some special order items like Japanese parts can be out of stock requireing a special order. We are very flexible though and we do allow you to cancel orders if you don't want to wait a lengthy period for parts.

If you guys have any further questions please just ask!

if your car is stock of close to stock ( < 200rwkw ) I would not be using a heat range of 7

They will foul way too quick, and your car will be running like crap at the 5000rpm mark if you have higher boost and no aftermarket management of some sort.

At these power levels, stick with a heat range of 6, as they will stay cleaner longer (In my experience anyhow)

you measure the supposed 0.8mm gap with a feeler guage.

So where do i get one of these feeler guages?

Also, say you buy some plugs that are at 0.8mm, will they DEFINATELY be on 0.8mm

IE is there anyway during transit or general handling that the gapping will change?

    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
    • Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.
    • @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
