VB cans work, bed in easily. I tried Four XXXX but got all crossed up and ended up in the pissed n' broke/piston broke club!!!!

Real answer - It depends on your power goals vs your budget. Standard takes more of a hammering than we all thought they would. Then theres plenty of aftermarket and none have a bad reputation, as somebody said its not the product its the build you get that is the defining limit.

Sort of good point. The reason I went with Tomei pistons is because I talked to someone that put 100k (over 10years) on an engine with them - had some track work too.

He had standard rods with tomei bolts. Rod ended up giving up.

So when i looked into them they seemed like the best option for a RB26. So far 12,000km on with them. Hopefully another 80+ to go.

I reckon anything Jap, 9 times out of 10 would have to be the best or close to it, they usually make/build as we know, great engines , so makes sense they will deliver an outstanding piston ( Tomei ) to put in there own designed/built engines.. :ph34r:

INB4 piggaz gets here and starts talking about jap cams and valve springs.

Here is a story.

Once upon a time.....

There is a bloke in Victoria from Pacific Engine Parts who supplied the piston rings Fred Gibson used for the Group A GTR's. Knows a thing or two he does. If you want a good piston get good rings and built the motor properly. We do good engineering in Australia too, you know. Or atleast did before the Chinese, the mining boom and the wrong headed notion that if it is from overseas it must be better destroyed all our manufacturing industries.

Oi how shit are those jap springs and cams!

Seriously though, they re shit

I'm not disagreeing haha, I just know he won't stand for someone saying how good tomei type b poncams are and the quality of Japanese valve springs. Really gets his goat :P

He isn't the only one with the same story, but basically it goes along the lines of fitted Japanese valve springs (tomei in mine, hks in his) neither had enough seat pressure and caused miss fires in his due to float, mine were checked before being fitted, both replaced with super tech and now fine

The real answer is..if you have to ask on a forum, you probally don;t need them...maybe a bit harsh..but true

cheers

So researching and checking ask your facts before pulling the trigger means you don't need them?

Guess all the cheque book racers who get 1000hp plus built lambos and the likes don't actual need after market pistons in that case?

Such a stupid logic some people have, not like I asked do I need after market pistons for 300+kw or something.

one of my tomei springs broke and wrecked my engine :(

Further make this a discussion about valve trains*

Not sure if true, but ive heard that valve springs can be damaged if motor is flogged cold? I cant imagine a mechanic in Japan working for Mines, to say no no no, don't use tomei, use only supertech!! lol... just saying... :ph34r:

Read it on Oztrack.com.au , there's other causes like bouncing off the limiter, overheating etc..

Pretty much..

I assume that you want way over 1000hp at the crank....to even ask the question..so my assumption is that you don't need them if you have to ask...

Ill put it to you that unless you done over 1000hp at the crank ..before ...that you will run into the same sort of probs that workshops that have done this have encountered..and that

you stockpile blocks and practice nuking cheaper parts first because the rods and pistons , even cheap chinese shit wont be your problem...

if your a chequebook racer, well just go sign the cheques, if you need to double check said workshops info , you need to find another workshop

sorry if i offend you

cheers

Nope aiming for 400kw with a little room to grow. Why not upgrade pistons if the block will be stripped in the build anyway?

Get my reason?

And no not offended just find sometimes people are rude on this forum to legitimate threads or questions for no reason and it doesn't help the community grow.

Not saying yours was but it could be perceived like that

Well just some random thoughts on general SAU stuff.

Try and avoid F&F/Facebook language. Whatever the merits (or otherwise) of such language a considered, well put together post to start a thread will get a much better response than something that sounds like it was written by a bored, trolling teenager in 30 seconds. (Not saying yours was quite that bad.)

If you had have asked for a piston recommendation for a 400kW build you would have got no end of people saying Tomei/CP/JE/Nitto etc etc. All of which are fine.

If you had have asked what attributes of a piston may be important on an RB you may have got a different answer again.

TL:DR. When you start a thread try not to sound like a teenager, try and make it sound considered, include what you know and understand that aside from just answering (or not) your question it may well provide information for someone else at another time.

Lastly if you think I should shove my post up my ar$e that is probably fair enough.

    • Reading through the engine service manual their advice is do a cylinder balance test. Unplug one injector at a time and see if the idle drops a consistent RPM. You can also do this using a Consult cable which is easier. They also call for unplugging the power transistor, then with the engine off and the fuel rail unhooked from the manifold verifying that you have good fuel flow (even injection, no dripping/leaks, etc) when you twist the CAS by hand. Also verify the spark by pulling the spark plugs and allowing the plugs to ground and turning the CAS by hand. I would also start doing the sensor checks and idle valve checks in service manual. Make sure the MAF tests reasonably, the intake air regulator is sane, etc. You may have to get new spark plugs.
    • 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.
