I have 4 stock twin turbo pistons (std 86.5mm) and rods for sale for the SR boys wanting to convert. R500 for the lot.

Hey 300sx what power diffrence will it make to the s14 sr slant top will it change compression ratio's etc.

it will bump up the capacity to around 2050cc... compression pretty much the same... but the shit is you need to bore your block!

I would of taken them, but i need 6! 😀

Will raise compression slightly... dish is apparently less than SR and then the bigger size will raise compression. Well thats what my research told me before...

bigger bore = less compression ^^
compression is very easy to fix just replace different thickness HG it sorted!

That is inaccurate. thicker head gasket yes will drop but bigger piston squishing more volume of mix into the same (or very close to same depending if you have done some mods) combustion chamber = higher pressure and hence higher compression.

Sorry did not mean to thread jack... free bump. 😀

oh well... have you see the Vtec pistons? there is no dish and it actually have a raised piston center... (i can be wrong here, but i have build a few engines and from firends car that is what i notice) i was talking about thinner HG^^ to raise not to drop^^

ok so more to the point what will you need to do to get these in the SR? and will they work with the SR Rods?
