High Comp pistons

[Dane]

I have a DA9 with B18A and prob need to do piston change Is it worth installing higher comp pistons?? Would I need to change anything else? Would there be much of a power diff?

Just getting some ideas whether I put in different pistons or just stock ones.

Cheers

if you get higher comp pistons, as you are increasing the compression you will prob need to run better fuel and maybe even need a engine tune otherwise you might get detonation

I already run premium fuel in it, can the stock ecu be tuned?

to tune a stock ecu you need to 'chip' the ECU with Hondata, Chrome and the likes.

Running premium fuel may not stop the detonation alone.

Since your in Melb, try contacting James, he's prob the best one to talk to in Melb, i don't know any other tuners there, and hondata is his fav ECU
