I quickly checked the Tomei price. Cooling channel version $3000 for the six, normal version $1780 delivered. the Mahle pistons are approx just over half as much.

As far as coating go I wasn't bothered with titanium this or that, or ceramic coating the crowns - more interested in a low friction coating for the piston sides.

HKS - part number 2103-RN017

lists as $2124 delivered.

2103-RN021 lists as $1585 delivered.

So the Japanese stuff doesn't appear to be particularly good value. It may, however, be more suited (As opposed to more generic although that is just conjecture)

How do Mahle pistons go for noise?

I'll have a look for Ross stuff also.

yeah you're right. for anyone without an unlimited budget these days the jap pistons are kind of priced out of reality. I can say though they are very good and seem to last. and very quiet too. dunno if that makes them worth twice or tripple the price of competing chinese and american pistons but they are good.

you can have the coatings done to any piston after you buy it but HKS (and others do offer various coatings) including a low friction molybdenum skirt coating like you want.

not sure of the mahle noise haven't paid attention to the one local engine I know with them in it. CPs seem to be not bad noise wise.

Can I ask where you ordered them from?

i got em though a forum member brand new when he ordered a set for him self. we went halfs in the postage and it came in welll under 1k. like 800dollor mark for 6 with everything pins, rings, the lot

: D

yeah I currently have tomei pistons in my car and as I said (and piggaz said) they are so quiet. you would not know the car had forgies and they are strong as they come. not cheap, but a pretty critical component so I don't mind spending a bit on pistons.

    • I thought that might be the case, thats what I'll start saving for. Thanks for the info 
    • Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.
    • Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
    • My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
    • There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
