Chris,
Have you got any specs on the Cosworth/JUN pistons? How about their rods etc Thanks

Most of the H section rods I have seen have been VERY similar. HKS/Cosworth/Farndon/Arrow/Carillo etc. all look like they have come from the same parents. I think all the bolts are the same spec too- 12.9 multi-heads like ARP. I know that Burton used to buy Arrows and market them under their own name, and I know that HKS used to use Farndon although I think they do actually do their own now because they got a BIG kicking on price. Seems like theres a lot of inter-mixing with things like steel rods and cranks. Probably because setting up the manufacturing for them is massively expensive.

Errrr JUN pistons are 462g according to their website. Didn't expect them to be 100g more than HKS.

Good point....don't forget that my weights were without pins or rings, which as Crhis says is not the standard method. I just couldn't be a?$ed opening up the relevant packets but if theres enough interest I might do just that to clear it up. It's a very viable point as pin weight can be dramatically different.
Not sure who makes the TODA pistons Chris, but knowing TODA it wouldn't surprise me if they had their own manufacturing. Remember that all they do is engine parts rather than the jack-of-all-trades HKS. I would have thought it would financially viable for TODA to have their own plant. They could be made be someone else though..... ....hold on, it's just been answered here, unless they are lying... http://www.todaracing.com/about/technology.html

Nathan, could you get the weight with rings etc fitted, so we have comparable data?
Alternatively, I don't suppose JUN has the weight of just the piston on their site, Martin? TIA

Brilliant. It would be nice to add as much technical resource information to this site as possible.
