Well guys I need your help YET again. I am in the process of buying new pistons and rods. But I have two questions that I must know because I want to build this correctly. Question 1 should I up my comperssoin ratio? ( note: I am not planning on adding a turbo ) if so what is a realistic hp gain by doing so? question 2 If I up my compersion ratio do I have to sleeve my block? Do I have to change by oem crank? GUYS I REALLY NEED HELP TO GET THIS DONE.PLEASE PLEASE HELP A HONDA HEAD LIKE YOURSELVES OUT!!

 

Anyone??

 

engine? You shouldn't need to sleeve unless you want something ridiculous way over 12:1 compression...

 

And the crank rarely needs to be changed, maybe micro-polished, but changed out to what?

 

what motor are you talking about? Is this a daily driven car? Honda cranks are bullet proof. If you are wanting all motor then yeah you want a higher compression. Just have the crank micro polished and you'll be good to go with that

 

OH SNAP I forgot to tell what motor it is. Well it is a b16a SIR II and it will be a daily driver. What would be a good comperssion ratio? I want to gain alittle more hp. THANKS GUYS
