you can buy them seperate from golden eagle im pretty sure, i got mine from a member on here. the one i got is 84.5mm, so i will loose a bit of compression im told. dosnt bother me too much.
are you looking at golden eagle or full race vtec kit? i will be going full race kit, cause i dont want to use the oil sandwich plate cause more of a chance to have leaks imo.
yeh im doing a B20 as well, slowly slowly.
