my engine need's a rebuild and i'm wanting to know if anyone has used the acl forgie's in there engine's yet? and what do they think of them?any good?

any forged piston is going to be good just as long as u keep ur car tuned and dont abuse it if u know its pinging

yeh,i know that. i had a chat to bresciani today and they recommended the ross forgie's so i might go with those when the time come's just asking for different opinon's thanks

my mate pulled his vlt down a few months ago only on 10 pound and had cylinder 2 piston fall apart in his hands and they were acl im going arias forgot how they spelt

i have apep.australian precision engine parts. they take the abuse.i have run them and pulled down the engine.no dramas at all.they have thicker ring grooves too to accept gapless rings.

The ACL forgies go for around $1,200 a set, not cheap. And I have seen them myself very high quality, Someone said to me they are made by Mahle but the packageing has ROSS lables, So I'm guessing they are made by Ross and boxed in ACL boxes. ACL don't make forged pistons in Australia they are made in the USA.

I think at the moment they are using Ross but will be using Mahale in the near future.

don't use ACL pistons. ive heard a fair few bad stories, i seriously wouldnt even consider them. do you research before you buy forgies cause they arent cheap. call a few workshops to get advice.

According to the ACL Website the Forged Pistons ACL use are the Mahle ones.

yes. mahle do make the ross forgies. they are the same thing

I'm running ACL Forgies. $1200 trade. Come in a Pretty box with Larry Perkins face plastered all over it, and a warning about not for street use. They are visibly different to the ACL Forgies in a Freinds RB30T which are of an unknown age, but may suggest manufacturer change.

Forging metal is just a process to make the material properties stronger. If the pistons have dodgy machining, thin ring lands and are not tollerenced exactly then they will fail quicker than a standard piston. I have heard many stories of engine builders that have built an engine up and found the piston to be scuffing the bore due to dodgy tollerencing either by the machinest or piston manufacturing company. Not all forged pistons are created equal. While the inexperienced and magazine mechanics might think that "Martin Donnon said forgies..... omg i gotta get a set now (*&!@#E@!" real engine builders will source a forged piston that is quality and accurate. If i was in the market for forgies, ide be doing a lot of homework to see which company is doing what kind of piston and what features are they incorpoerating. Paying an extra $25 bucks a piston and to know its quality isnt much in the end when it will save you thousands in the long term.

all i can say is call australian precission engine parts. thats if aftersales help means anything to you.they stand by their products and customers
