Nick - didnt realise that the engine for the ka was running std cams head and also silver top rods....

I knew about the wosner pistons and the mappnig side and the power it produced.

Thats an intersting point that you have just made.. may hang onto the std cams now then! lol

everyone else... the only actual advice that was given was by luke so mitsy if you would like to offer advice rather than speculate that im simply using the internet to hear what i wsh to then put the info on the screen then mate....

1. it wil not be using 95 ron cos its cheaper!
2. its not an internet spec... i have speced/got these parts cos i wanted to have a higher CR ratio than alot of the other ZT's
3. its using the std ford MLS blacktop had gasket, if the CR is slightly out there are things that can be done (cometic gaskets is the cheapest first option) 2nd is diff JE pistons and go 2.1 with custom spec ones.
