before all of you start i have done a search and havint found exactly what i want Just wondering on your opinions of these pistons for a rb30det bottom end and a supply up here in QLD I want to build a bottom end be able to handle 250rwkw-300rwkw with these pistons and would the standard rods shot peened be strong enough for this power figure All opinions welcome and Appreciated

l wouldn't use the acl's seen quite a few broken ones at my bro's workshop.

i use these pistons in my rb30det, i have been told by plenty of people they're fine for 300rwkw's. Shot peened standard rods will be fine!

^^^^^^^^^^^^^^^ all u need to know i use them in many engines only one has faild due to tuners leaning it out and putting a hole in one

^^Agreed, most peeps only need forgies cos of lousey tuning!!^^

yeah my rb30et is getting a bore atm then im fitting hypatec pistons... supposed to handle bulk power

hypers are around 450 with rings these days

If it's tuned right standard pistons have seen 300rwkw's many times. Any decent forgy will be ok a that power level, never seen a piston fail because it was an acl. $450 with rings,where you getting them from. Nissan (holden) want $675 for piston/rings.

were abouts you getting them from

just got off the phone to my supplier i can get them for 600 with rings per set in single sales i was gettin them in bulk before hence the sweet price if yous get a order in so we can get a few sets at once i can get a cheaper price for every one, they are the hypertech turbp pistons with anadized crown and moly rings never had any issues with them and many ppl give them great feedback

Just if anyone isn't quite sure, your pretty much stealing them at that price. might have have some friends who are interested.

im interested man my blocks apart now so hell yea ill get some

well who ever wants some put ya name down in this thread only ppl with the money need apply... and i can probly organize free postage str8 to your door

so these pistons hypertecnic are they cast then triple coated in some sort of strenghtining stuff ?

there cast with a anadized crown to with stand more abuse they come with a raised pin height also wich will take compression to 7.1 or u can get the normal 7.8.1

ive gotta get my block preped and messured so once thats done ill grab a set off you how much though and what bore sizes do they come in

well ill probly get the 1ml one cause ive got some nice scores in number 4 were the piston has melted abit on the side an there like welding slag around it and its just fu cked the bore

haha $650 including rings. i got mine last week of paul at vpw for $550 including hastings rings. 20 thou over too. i think you need to have a chat with your supplier Some original photos have not been recovered yet.
