We did a compression test on a 94 SI hatch the othe day and yeilded these results: 130-125-125-160 (in order of 4-3-2-1). We then added a capful of oil in each cylinder and yielded these results (165-170-170-165). Rings were probably shot after boosting 10-12 psi for a month or so. My question is: Has anyone tried that RESTORE engine lubricant? Is it only a temporary fix to the problem or do the rings HAVE to be replaced? Thanks.

i wouldn't try any temporary fix. Have the motor taken apart, replace rings, bearings, and if need be, replace the pistons.

 

I ran it in my car. It hasnt seemed to help at all. I am looking for a D16 anyway.

 

thanks for the quick reply guys. New rigns i guess it is? what oem honda pistons will bump up the compression a point or so.? b16?

 

CTR pistons... 11.?:1.. I forget...

 

B16 pistons yield a higher compression ration then CTR pistons in a B18C1.

Here's a website to a compression calculator. You will notice that JDM B16 pistons yield the higher compression ratio.

I think he is taking about a D16Z6. 94 SI hatch? If so you can use D16A6 pistons.

wheres the imformation police........cuz hes giving out false information.

 

closest you can come to boosting compression by 1 point with oem pistons in a d16z6 would be with d16a6 pistons which should give you about 10.8:1. Use a turbo headgasket to get it down from there....otherwise use the z6 pistons.

Using that calculator, I came up with a 11.9:1 compression ratio with JDM B16A pistons, and a 12.4:1 compression ratio with JDM B16B pistons.

Maybe you should try using the calculator again before you spout bad info.

 

anyone have the compression results of a healthy d16z6? im running a test soon.

 

175-185 range for fresh engine

 

I turned the engine 4 times and got around 130

 

130 on all cyl? thanks for the specs, will be doing the test tomarrow. engine feels good, i hope the test proves me right.
