The rb20det apparently has 210kW at the rears and the Vg30det 198kW so would the rb's fuel consumption gone though the roof?
rb20 will get that if you spend money on it there is no way its getting there stock, i got a rb 25 and so far we got 187kw but we are having issues... but we should see 210 if im lucky.. thats stock and done to many km ... but shit im shutting down VE SS,s like they missed a gear ...
