sorry i have not yet gone through the search bar, my comp seems to crash when i do it :(

if i plan on running between 12 - 14 psi boost with phase 2 cam, what cr do i need ? how much do i need to get milled off the pistons (if anything) or can it be taken from the head ?

cheers Iain my pistons are the stock 1275 turbo ones, not sure what cc the dish is though. the pistons are stamped on the crown with --> 2083|1D17 and the letter A stamped in the middle. iam prepared to use octane booster if needed, i used to have to run 101 octane with my old n/a engine the car is not an everyday car.

cheers , is there a set amount to mill out of the head ? i would prefer to take it from the head as i will have to have my pistons taken from the rods and the rings removed.

Like jim says, 8.5 is a good compromise.

Off boost power and room for some boost.

Have the pistons machined if possible, i know from experience you can find 15cc out of them and volume in the piston is ideal.

12cc ..bit oppitisitc ( spelling) ,work out your c/r, 1275/4/ + all the air (ie piston dish +head camber cc +ring land + deck to piston height) and / by all the air

Everyone knows that instructions only have to be read if the thing doesn't work....
