Anyone know where you can get one that includes comp height, pin diameter and piston diameter? Been googling without luck. Something similar for European cars would be a useful reference.

Google Wisceco

Thanks, for some reason their motorbike catalog doesn't seem to have comp height, sometimes pin diameter but their automotive does. Maybe have to look a bit harder.

Unfortunately this info is very difficult to source,
you best do as I did and scrounge through ebay
they sometimes have this info on some ads.
What size you after and for what build?

Ive had the same trouble also, One option is to get the piston diameter and pin size info from the net. Then go to a good bike wreckers and measure the compression heights of the second hand pistons. Also good because you can trial fit a second hand piston and machine a bit of the top if req. All before spending good money on new pistons.

Im looking at forged Honda pistons for an A12 at the mo.

What are your plans? For A series? Turbo or NA?

Got a few ideas but mainly looking at options. I have an A15 and would like to go e85. Also have quad efi throttle bodies and bits and pieces to build a manifold. Another part of me like the idea of a turbo. So really just looking at options. I have read about high comp, high boost engines using high octane + water injection and this to me sounds interesting as e85 + water injection would potentially give you great performance and respectable fuel economy.

Mostly ideas though, efi, throttle bodies and coil on plug first. Significantly more power will mean drive line upgrades have to come first....

e85 and fuel economy on the same line dont mix

www.specialpistonservices.com SPS use to make my custom bike pistons, they will make anything. there in Dandenong. Give em a call they are helpful and have good knowledge of bike pistons

Simon, keen to know how you went looking at Honda pistons, if you got any further with that. It's something that's still bubbling away in the back of my mind.
