I just bought a 88 civic hb with a zc. It has a rebuilt zc and he said he had the head milled to 10.7:1 compression. He also says he still uses 87 octane gas and I did not hear any pinging when I test drove it. It also has adjustable cam gears so I don't now if he backed down the timing.

 

then tune it

 

if the motor can handle it you should be able to run a farly big turbo.. if it can handle it run a big turbo and propain injection HAVE fun

 

turbo if your gangsta.....insert coolio now

 

10.7 is right where I'm at. Boost it.

 

turboing would be stupid guys my buddy has a supercharged integra running 10.5:1 and they had to tune such on the safe side that he really didnt even make any more power after he got it back. i would say sell the engine and get lower compression highcomp=big problems just beleive me.

 

Thats because it was supercharged! lol
Was it intercooled?

 

no but still it is capable of working yes but it is much easier with low compression im i not correct?

 

ask him how much it got milled... cuz 10.7:1 is a .050" mill, and thats quite alot for a rebuild..
