The specs were up on here :S seems when ive edited my add ive done something wrong..

Either 2.0 black or silvertop as the block height is the same, and they share the same crank... Just the rods & pistons that are different between the two.

Brand new Forged Steel H Beam rods with ARP bolts

JE Performance Ring set

JE 2618 Forged aluminium Piston set - including the pins & locking rings

Combination is good for 900 HP naturally aspirated, boosted, or Nitrous use

Bore: 85mm

Compression Ratio: 9.0:1

The compression ratio is for turbo applications running a decent quality fuel such as super unleaded – 98 RON

Obviously this is brand new, and cost me well over £1000 by the time I had paid import duty, handling fees and the original product price
