People use them here in Aus in all sorts of motors, N/A, turbo, whatever. I've never tried them though.

Supercharged 1964 Morris 850 - Now 1330cc with 7psi.

im using 1100+60 hypatec pistons + hastings rings atm for 10psi boost with no troubles done 10,000km on them.

very cheap too

1152cc turboed mini clubman, most powerful 1.1L a-series?

just got a 998 set and a 1275 set in (5 days from Oz to here.. 14 days for customs to figure out how much VAT they where going to charge me)

the larger sizes are the ones without the slots.

1275 +96/73mm:






998 +120 ! :

I bought a set (73mm) from Minisport Australia (through this site, he advertises in the "for Sale" section).

Also the larger ones without slots...

I will be using with turbo (but my project is taking far too long) but I haven't yet decided how much I dare machine out of their current dish, they only have 7.6cc as standard.
They need enlarging slightly otherwise I'll have to take enourmous amounts out of the head.
They look thick enough in the crown to have a fair amount machined out but the underside is a bit of a strange profile.
I also got them at a VERY good price - UK customs managed to ignore them and they came through with no extra UK duty/VAT (sometimes you get lucky!).

Schrödinger's cat - so which one am I ???

I guess the only way to tell is to cross section one and see how thick the crown is!

At £30 odd a piston not as bad as cutting an Omega piston up!

1/4mile in 13.2sec @ 111 terminal on 15psi

surely someone on here has access to an x-ray machine???

Maybe wolfie could keep one in his pocket? He seems to be the most unluckiest, then he could just flop it out on his next visit to hospital

I'm seriously contemplation asking if i can get a radiologist friend to put it in a CT scanner (if his bosses don't freak out)

Any opinions? hastings rings look like great quality from there website....but are really cheap. Im just doing a stock rebuild. (Car will be running ST autocross)

I had some cheap NPR rings that came with some other parts I bought....just for fun i tried to install them on a pistons and the 2nd ring snapped right in half. Glad they are not going in the motor.

For a D16A6
