Got to get some oversized pistons as found out today my block need reboring more than std so thinking of getting some +1mm accralite forged pistons for my rs turbo.
has anyone else got some and have u any problems with them my last engine had some in it but rod snaped and destroyed them so didnt realy get that long trying them out...#

any info please

cheers
jon

 

i have used them in me 2.0 zvh its not running yet so cant coment but the service was excelent and they look well manifactured

 

Iv'e got them in my cossie but its only done 1700 miles since the rebuild.
Bought from Burton's

bttt

 

good, but noisey when cold

 

cheers mate
just im about to order some an dont want to make the wrong choice

 

ask if ther vacumed froged as cosworth racing do them and rate them the best over any other coz ther vacumed forged

 

CHANGE THE RODS AT THE SAME TIME!!!!!!!!

 

speak to Tillio.

he doesnt recommend accaralites for sum reason. I guess he must have one?

 

They are a copy of the Cosworth Piston.

 

the casting process by cosworth is probably different pal and if they sounded like yours id bine them as they sound fooking terrible and sound like none of the cosworth racing ones i have heard sound like the ones of yours diesel

 

bttt

 

Gus, mine is very very quiet when warm. Just dont sound their nicest when it's 2 degres first thing in morning

 

Mine are silent when cold.

Whoever has noisy ones must have a problem with them.

 

I have Accralites in my car and I think they are the dogs danglies . No problems what-so-ever and the engine's been abused for around 20k miles now and doesn't use hardly any oil (still) - ¾ level on dipstick to ½ on a track day !

 

have heard on the authority of a very well known tuner on here that coz they are flat tops they dont perform well with the shape of a cossie combustion chamber which apprently requires the dish for squish.

 

but were talking for an RST here!

I have 1mm oversize accralite pistons in my RST engine so i know what they sound like!

it sounds like a bag of nails when you start it! ie like a diesel however once they have warmed up they are mint and dont make ANY noise at all.
As far as im concerened they are a very good piston and are a fair bit cheaper than 'cosworth' ones.
however they will create more bore wear than a mahle or similar as they have a central gudeon pin and are a 'propper' forged piston.. hence the rattling!

As above Mine are cosworth, with central pin. Cold = noise, Hot = silent... If they are silent from start then the bores arent the right size...

 

oops - no one said
