A question: ECU for bigger engine

[Sparco]

300ZX Fairlady Z Z32 twin turbo 07/90

Here it is

Now I have 2 engines: one stock, and one dead now (burn through piston due to injector malfunction) so the cylinder block should be repaired and the pistons should be changed

A suppose that a can use pistons from 3000GT twin turbo ( dia 92mm) instead of mines (dia 87mm) so than the cylinder block should be turned till dia 92mm, am I right? I already got 2 metal gasket from greddy-trust for such diameter of pistons

So the question is: could the motor work properly with the larger volume? I think it will be 3,350 liters with standart ECU but with fuel regulator, fuel controller, boost controller and same shit????


thanks to ALL

well it's going to change your compression there for changing boost I'm not sure how to figure all that but I'm sure there is somewhere you can find out.
