I need to get my 2 litre bottom end rebored and new pistons to suite as its decided to let oil up piston one.

Wheres the best/cheapest place to get pistons from and how much is a rebore to 2.1?

Thanks in Advance

Rick

Burton do some acralite's that would be perfect.

Yea have accralites in the engine i'm selling , top pistons

reality

Most people go with the XE pistons..

Ad4m RST

Yeah the C20LET pistons if you're on a budget

reality

Not for a ZVH you don't.. not unless you want to run methanol and 40 psi

Ad4m RST

Under the impression these were the calibra turbo pistons? quite commonly used in zvh's IIRC

reality

No, you use the n/a astra (XE) pistons in zvh's and the calibra turbo pistons in zetec turbos.. the cvh head has a much larger combustion chamber so requires a piston with a smaller dish to maintain a reasonable compression ratio..

I'd use accralite's if only for piece of mind. Ur not going to ever break one unless its setup wrong.

I use custom forged items at 7:1 c/r. They take a lot of abuse! If you go custom you will get the best, not an average item. Obviously this depends on your goals.

what sort of power can calibre turbo pistons take then????

reality

Proven to way over 400bhp.. but if you mean the XE pistons (as per ZVH) then 300bhp proven..

FULLBORE

well if they can take 400 bhp,then how are these BUDGET pistons???
not many zetec t's runnin more than that at the mo.

could these fit them EAGLE STEEL RODS THEN??????

James-W

don't you mean 500

because their cheap

Rick

they're mahle's aren't they?

The cossie mahle's are good for 500hp, the cvh ones tend to break their ring lands with much less power. I'd buy a nice set of forged accralite's, not that dear in the scheme of things.

FULLBORE

but everyone i know who have had them say they are real noisey on startup because they are real light pistons.i couldnt put up with the noise cos im fussy

Rick

They are noisey on startup, because they are forged and expand differently to cast. I have Cosworth racing ones, and they are a little noisey on startup.

FULLBORE

im fussy but im not plannin on over 330 so calibre turbo pistons will do
extra money to spend else where then

Vampire

so the calibra turbo pistons will fit a turboed zetec,

what do i need to get the walls baored to?

reality

Whatever the diameter of the pistons are plus the tolerance given by Mahle (or AE).. You do need to machine the pistons though in a few places.. and modify the rods (unless you get the rods specially made for the pistons)..

Ezzy Danny

nice one for the replies guys got some ideas now.

Rick

forged tap when cold, and remind u not too boot it
