Long story,,, engine still runs but up to piston replacement time and head reco time,, can anyone point me to a replacement piston that will be better suited to the turbo and have same installed height on the std rods. I presume there are aftermarket better suited ones, just wondering what some guys have used.
Cheers

There are aftermarket turbo pistons for 1hz, but from what I've read, you need to change rods to 1HD-T rods as turbo spec pistons use the 1HD-T gudgeon pins which are larger than whats in 1hz

You can buy a turbo upgrade kit for the 1hz and its about 1600 if i remember correctly.You get pistons rods gaskets seals etc new head bolts rod bolts and all assembly gear required.Its a good kit and has been working well in my 79 series for a while.I also got a new head and this was around 900 aftermarket.

What are the options regarding factory/genuine pistons? Treating, ceramic coating etc??
