A mate recently bought a a complete ZVH with steel internals & the bloke gave him a brand new set of nissan pular gti-r pistons on standard zetec rods with it. He said he was going to use them before he went the down steel route.

I know only really of the calibra turbo pistons being used & even a few running celica gt-4 pistons but never these!

They dont look like pulsar pistons?

It's very similar to a Supra piston.. 86mm bore.. 22mm pin.. ~32mm compression height..

It will fit in a zetec.. not sure if the skirt will hit the oil squirters though, only one way to find out!

The compression ratio wont be very low - it's only 1mm shorter compression height than a standard zetec piston (compared to 3mm shorter with a calibra turbo piston)..

Probably be fine for a ZVH though due to the larger combustion chamber? Best to dummy build and measure to know what's what. Not sure i'd be happy with boring out the standard rod to 22mm though.. That's 1.37mm oversize.

iirc it should have 54C stamped on the top if it's a Pulsar piston and it would probably outlast the Zetec rods in terms of power.

pa_sjo

Not if it's detting it's bollocks off if the compression ratio ends up too high and is poorly mapped

Although, det is a rod killer too, so perhaps so.

Jamz

True but the same applies to proper rods and pistons too

Well tbh the boxes they came in ar for a pulsar so does'nt ness mean thats what they are!! I'll double check the pistons

The standard pulsar pistons seem to be pretty weak from what ive seen.

pa_sjo

That could be down to a fairly high CR and crap tuners though

Twat one with a hammer and centre punch, they are soft as shit.
