get a JE 10.8:1 and run 93 octane. Much better than wiseco and you wont need race gas
so if i do go with W than ill need race gas?\

if you get a wiseco 11:1 you wont need race gas. if you get a JE 10.8:1 you wont need race gas. Any higher on either and you may have to start mixing in some race gas. The reason it is different between the two is because wisecos compression ratios are lower then the advertised. JEs is more accurate
