You really need to be a bit more specific,

What's the aim of the build? what other parts have you got to go in, may give people a starting point with the help your require

Arrow rods

Acl bearings

Owen development gt30 based turbo

Magnex full exhaust system decat

900cc Lateral injectors parallel

Fuel lab fpr

V3-4 sti heads

Lightweight pulleys

12mm modified oil pump

Exeedy organic clutch and lightweight flywheel

Oil catch can

Would these omega group n pistons run with that set up ? Is that more specific

Whats you target hp and what's the car gonna be used for ?

I've never personally used the omega pistons before ,so without knowing much about their spec , im afraid i can't help there . but i have used mahle pistons.  They do 2 main types forged (good for 500 hp) and race (good for 750 hp) .

I've always got my engineer to check the bores for ovality and taper ,then decided whether the bores just need a hone or a 0.5 mm overbore (with oversized pistons) to be within spec .  

You probably already know but If you intend on using a ej20g cdb you'll need your engineer to convert the crank thrust to take the later nitrated crank .

I'd add headstuds and cossie headgaskets ,once you know the size of you piston bowl (to calculate thickness required)

If it's gonna be used on track ,id also add a baffled sump and possibly swirl pot  too 😉

Thanks for the advice guys
It was only supposed to be a fast going road/track car lol I only bought them because they were near mint and cheep so I don’t mind selling them on again I only ask on here as rcm we’re like no help at all .. personally for me seems like a lot of agro to fit these pistons I’ll chuck em up for sale and opt for a different set :)

yup most suppliers are not too keen giving information about rival kit - however given the information from @Mr B just factor that into your gasket size as you will need to purchase those anyway??

I’m sure they are the supplier for omega pistons ?
All they wanted me to do was buy there rods and crankshafts [emoji23]

Anyway I shall get the calipers on them later and have a measure up I’ll post my findings and see if one of you helpful chaps can give me a direction :)

Cheers dudes
