I want to raise my compression from a 10.2 to around 11.7:1. Could I get away with milling the head to gain the extra compression, or would it need some extra help? I want to try and do this as cheaply as possible.

Thanks! I did some searching before I posted, but I didn't find anything like that. That's incredible...

 

Just keep in mind that if you increase compression through milling or a thinner head gasket, you bring the valves closer to the pistons, increasing the chances of a collision. This is a particular problem if you plan to run bigger cams and/or try to adjust timing away from stock with adjustable cam gears. So if you are increasing compression to run a bigger cam, keep this in mind.

that link is good stuff

 

is that wrong or are only usdm pistons pr3s? because my "jdm" b16a is a pr3...

 

Don't worry, no aftermarket cams here. I'm leaving everything stock, just looking to pick up a few horses relatively easy. My head gasket is bad anyways, so I figured why not. I think I'll go with a 2 layer head gasket, 1 layer would probobly run too hot. it also looks like I can only mill off .02 before I have a problem with piston clearance.

 

To mill your head enough to get 11.7 compression would mean removing the entire quench area. Even on stock cams, you would have a excellent chance of piston to valve contact.

 

Don't worry, I alreaedy checked it out, and it looks like 11.2 is the best I'm going to be getting without doing something else, which is out of the question because I'm broke as a joke. That website really helped.
