I am running the venolia's in an RB25, I chose them for the thick ring lands...and the fact that I am using the moly rings the thickness of them is not as important as using other ring types.

Yet to have a problem, and running almost 5,000 km's without a problem, and they are quiet!!! Well for forged.

I am also only running standard boost until suck time as I can afford the ancilliaries, but when you own a house and have a missus...the car comes a distant 3rd...

How good are the times now when we have a large choice of pistons and at very good prices unlike the old days(not long ago) when we had to pay a couple of months wages for Jap pistons and they are no better and in many cases the same piston re boxed.Best of all is all brands are very good.

We used to have upto 12weeks wait also and this was only around 2000.

im running trust\grex pistons. at 1.9thou what they recomend.

very nice piston.

although the rings are really expencive. i had to freshen up my motor due to a turbo blow up.

600bucks for rings.

no blow by at all. dead quiet.

a friend of mine uses je in his rb31dett 4thou clerance. aparently it brieths quite heavily at 1.8bar. although it does make 520kwatw

general rule of thumb is the tighter fitting the piston

(forged) the better the materials and the better it will perform,with less blowby

I have built a GTR engine recently using arias pistons and the rings supplied.

The engine has only covered 800ks and is using oil excessively.

All the rings seem to be leaking to some extent.

Anyone else care to share any problems with these rings?

Did you check piston to bore clearances ? Ring gaps ?

Piston to bore clearence and ring gap is fine.

This is for an engine at work. (im an engine reconditioner)

Not sure what oil was used, its a customers engine. I will ask him though.

The bores were wet with oil. :)

Just seems a few people have said the standard arias rings are crap and was looking for simmilar cases etc.

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
