Ok well my setup is planned to be this-

B18c1-block and head(stock cams for some while)
ITR slugs
Spoon Headgasket

-What would be overall compression?

-We can use 93 octane here in florida, my question is will i have detonation issues becuase my compression is too high? Will i have to go w/another head gasket?

-I also plan on getting .25 oversize. I guess i will have to bore and hone some .25 more. Will stock sleeves handle this? What is max that can be bored/honed?

 

??????

 

ive got jdm itr pistons in my gsr block w/ gsr head and im in SC. Its my 1st n/a build(always been a FI guy) and w/ 93 its just fine. W/o the spoon headgasket i believe the CR is around 11.4:1....everything should be just fine

 

where in sc

11.4:1 W/O the spoon headgasket?? What about with it???

The spoon headgasket will bump compression, if i'm not mistaken.

 

Should be about 11.7ish range with the spoon headgasket. I have jdm ITR's in a gsr with the stock headgasket tuned on 92 octane and its runs great. Compression test results are 270 psi across all four cylinders for my motor.

 

its 11:6 comp and you ll def have no problem with it using 93 octane.

well if your going with 81.25 pistons then your comp will be 11:7 .
the max you can safely bore out your stock sleeves is to 81.50,
some people have gone with 82mm which is not and overkill
and AN-R sells for a good price.
and some even up to 83mm,but 83mm would require some really good
ems tunning and good fuel.
