You prob know Simon used PJZ pistons for
one of his builds with machined tops


Looked at using these but could only find +1mm oversize which came to 76mm
need .040" over

Zigmondo I have some offset dish pistons I pulled out of my spare A15. I could press one off the rod and send it over to your piston supplier if those are the type you wish to use.

hey D , I recall you telling me once , it may be cheaper to re-sleeve back to 75mm - 76 mm and use suzuki pistons than go forged

Im not sure thats his problem though, but its even better if bores are thin to re-sleeve for the 80mm then grout the bottom end. Sleeving is around 450-650 with hone then grouting can be done at home up to the welsh plugs. These forgies are suitable depending on compression needs eg. low comp (small chamber head)

higher comp (A14 crank/rods but A15 crank will need deck reclamation process to raise the deck 1 or 2mm before sleeving. A common on industrial and defunct engine blocks)

I think at 80mm , thus reducing the gap between pistons may lead to blowing head gaskets under boost?
Not going to risk it
I'm going to price up the re-sleave option for Vitara pistons V custom forgies

Do you need to re-sleeve your block which A series is it?
The quote i got 5 years ago was from Footscray engine reco
spoke to George who seemed the nicer one vs the gay bikie.
Had 2 a12s bore and honed there on for stock slugs the other
for A15 pistons for the sneaky A14/A12 1361cc stroker.

Both were early block with dizzie at the front for easy rego.
Also had my crankshaft balanced after using my angle grinder
to clear counterweights to fit A12 pan and rods suit a15 pins.
There are prob some good places your way but the ones I preferred
in the past have closed down or been sold on to others.

If I had to do it again, Id do the sneaky stroker A12again
that great torque from down low and went better than my
fresh stock A14 before it (both used the head, stock cams,
exhaust system, elec dizzie and inlet with same carb settings)
but got a canary so hence went to the SSA12.

Prob suits a turbo better than stock a12 or A14 I feel as the
pistons travel faster away from tdc due to short rods reducing
the rod stroke ratios that could reduce detonation.
However maybe the lighter rods and pistons play their role
on the overall feel of the acceleration vs A14 etc etc.
