Arias Pistons

[Bobjones]

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 ?

What oil r u using for run in?

800K's is not much may reduce quite abit aftre a few thou if using hard performance top rings

[fatz]

my aries used some oild up till about 3000km

but now she is apples

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.
