Cheers for the comments lads,

@ Aidan im normally seen arsin around portlaois/abbeyleix when i get the chance to take her out....

Yeah she was rebuilt in japan to 2.3 by boring out the block and dropin in some RB-25 forged pistons think its a fairly common upgrade on the RB-20 over there all tho if im wrong im sure the techies on here will set me straight........
