I have added 3 pistons to my list today...

Started to breath into the dry sump tank heavily and once we stripped it down found 2,4 and 6 have melted away the ring lands

Not sure of the cause yet but will be checking injectors etc before blaming anything else.

Yeah I only did 10 laps in total. Really annoying as it had good pace in the morning, with more to come.

There's always next weekend....

Ill get another set of slugs and have it back together and running by saturday night. Just need to find the cause, so far all the data is showing everything to be reasonable. But number 3 EGT is slightly higher than the others which is also the piston it melted.

oh yeah I remember 2 other things I needed to add to this thread.

I recommend removing all nuts and washers from the inside of your intake, this one cost me a motor (spun bearings and scored bores)

and an transfer case. I snapped the chain. I'll post pics later it is a pretty amazing acheivement.

Brad it might be your thread but you still need to post pics....

Ill put photos of the piston up tommorrow. There at the machinists but ill get them back tommorrow with all the other stuff.

That turbo is fairly rooted! Ive also been through a fair few turbos and my current ones are pretty average too.

Na the piston didnt do any damage other than to itself really. We have checked the valves and head. There is a few cosmetic marks on the squish bands but nothing that wont clean up with a surface grind.

Small mark on the bore which is a deposit not a score so it will be lightly honed and reused.

Pistons will be done tommorrow, set of rings, bearings and gaskets will see it back in action.

Sam was here tonight checking everything else out engine wise and the injectors are being tested tomorrow as well.

Ill use this engine again for a few meetings and re-block it when we have a 3 week break and I have another block preped ready to go.

The turbos are more so damaged due to the lack of air filters and dusty circuits we race on. Its something i've been trying to get sorted but driving the car has become priority over making up and intake, kinda backwards really but oh well....

Best photo I currently have, there is about 80%of the top ring land gone and its burnt all the way down the skirt.

I came sooooo close to that one myself Dunc. Got home from a cruise on sunday and popped the bonnet for a quick look see and crapped my pants when I saw one of the backing plate bolts was missing from the air cleaner.

Knowing that there was a nut on the inside of the filter made for some heart in mouth stuff while I took the filter off.

Huuuuuge relief to find the nut laying in the bottom of the filter.

One redesign coming right up.

My bottom end is all assembled again!

Ill be chucking a head back on it tomorrow and will be sweet to go again.

Block is a little average now and Piston to bores are 1/2 thou over what they were last time but oh well.

    • This sounds very old of me, however since buying the Tiguan shit box, my view on shit boxes have changed.
    • I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way
    • This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.
    • Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.
    • To be fair it's the other way around. 300kw is boring in a modern Golf or BMW. They are so competent / well-engineered / devoid of emotion that you have to go stupid fast to feel anything. Whereas the <300kw RB still makes all the right noises and it feels good to drive. Can pull off at the lights with the turbo whooshing and the blow-off pssshing and feel like the coolest kid on the block. Just don't look to the side where you'll see the bored housewifes in their shitbox Yaris/Corolla/Camry that kept up because you didn't go fast at all
