Before you buy the factory Nissan pistons. Check the price on forged aftermarket pistons. Factory pistons are not a great deal cheaper and buy the sounds of things (You have a cracked piston or two) you perhaps should look at forged. you can get ARIAS pistons in standard bor AP331182, 40 thou over AP331181 and 20Thou over AP331180

Forged pistons are simply more durable (Stronger) than a standard piston. Changing the pistons to a forged type does not increase power as a stand-alone upgrade

Forged pistons are less likely to break if the engine is badly

Forged pistons in a well tuned car will also handle more combustion force (More power potential).

The fact that you have dead factory pistons at the moment possibly means that you have had something go wrong in the past (incorrect ignition timing, bad fuel or lack of fuel (AFR incorrect).

Forged pistons may not have saved the day but they may have prolonged the engines life before it lunched its self, depending on how bad the problem was. The fact that they are about $1,200 for the set inc rings, and pins (ARIAS) it’s a logical choice in my book.

.....will restrict reving, and i will need to have my engine re-balanced correct?

= big money.....if i only want a daily driver i though s15 pistons would be a cheaper alternative. And it ticked ever since i got it from japan, turns out yes the engine was cooked and one piston couldn't expand anymore so it got a mil or 2 longer, making it tick everytime the piston went up and tapped the bore.

The pistons are already ballanced but you may wish to recheck them when you get them. The engine will not have to be modified to take the pistons except for the bore. If the bore is damaged you will need to take it out 20 thou. and buy the 20thou over sized pistons.

The national distributor is Rocket industries in NSW. You can get them retail from any Autobarn Store on a customer special order basis. use the numbers that I specified. good luck!

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
