Someone get this info or Im gonna pinch the a15 forky from Stavros at the fresh food section a Vic. Market

ok ill put all you guys to rest the flat top pistons only come in A12 size bore 73 mm i can get them as a cheap flat top piston

73mm flat tops? then wed have to run 6mm thick rings
were looking at sizes above 76.
thats 78.5 - 79mm.
stevos 1000 a15 has 1497cc maybe hed know? hes running 78.5mm pistons... you there stevo?

sorry 63 mm pistons my mistake

You must mean 63mm in length?

I am going to Canterbury Mazda this morning to find out dimensions of B6 turbo pistons

Can't anyone tell me the specs of these pistons! Even the Mazda parts department can only tell me the diameter!

I give up on these oversize rebuild Im going rotary!

I've managed to find a second hand B6 turbo piston to measure, it has the same pin height as the non turbo (32mm) and just has a large dish to lower the compression.

I feel so let down that no one can tell us what to use for an a15 oversize rebuild. Especially for datsun modifiers like us. It seems people use the a-series as a stepping stone to something else and we are the ones who scramble through the scraps to make a little difference. I cant even trust anyone to do machine work like balancing in fear they wont do a proper job. This she'll b right attitude is the scary thing about getting anything done right. Its a shame to be in this boat with the only people to save us like nismo charging a fortune for the goodies we need.

I've spent a lot of time recently speaking to different engine reconditioners around town to get info for my twin cam conversion and I will use the Mazda B6 turbo pistons.

I am building a test engine where the only machine work to speak of will be the boring to suit these pistons, i'll then run it with as much boost as I can, see what its like, then build a good one (if it's worth it)
