Not that large displacement gains but maybe magic is in the details.

So what do we reckon, same price as the car or a bit cheaper…..

You can buy "just" the stroker kit with the larger pistons for about 11,000 AUD.

I would much prefer an over-squared version, allowing to keep the same crank (which not seen yet as weak point) and upping the bore with better/stronger low compression pistons. Ev. reworking the block for a close-deck(!!) and higher HG clamping force.
That would likely to give an happy hi-reving engine

I'd really like to see the differences in the stroker kits between HKS and IRP. The HKS built engine would be lovely. I'm guessing Syvecs and Motec are capable of running the pre chamber ignition?
