So when it comes time for an engine rebuild, or maybe if I just get bored, I want to add some higher compression pistons. So how high do you think I can go on 91 octane with stock engine management, stock thickness on head gasket, and timing without breaking something? I'm hoping for at least 11:1

I'm hoping for at least 11:1 how do u plan to run stock engine management? i say get one of the performance pistons kits and bore it out to 80 mm and get the 11-1 compression pistons and you should be good to go with a piggyback on 91 octane |

i've seen some people increase their compression with pistons and keep everything the same, they were just careful not to go to high and use higher octane

It would be easiest to use the Vauxhall Corsa 1.6L pistons...... 10.5:1 as these will work with your stock cylinder head and current lift configuration.

doesn't high compression, low displacement usually mean lots of low end and not much else?

Cool, i'd like to try 11:1 but I think I can be happy with 10.5:1. It's still more then a civic! doesn't high compression, low displacement usually mean lots of low end and not much else? I dont know about on a low displacement engine, but I know usually you get an increase on everything Daniel, this is your conscious. You should definately go for it and go for it now. |

I am using 81.0mm 11.1:1 high compression piston from wiseco. Having 155hp and 202Nm on wheel now with 275 degree camshafts (custom made). So what you mentioned few years ago can be done. I have done it.
