TougeIS200

just read this thread and very interested in this 1j-gte-fe hybrid. is it just the conrods and pistons? what about the crank? and isn't the 1jz-gte a 2.5 litre coz the 1g-fe is 2 litre! sorry for the stupid questions but am new to piston engine tuning. been driving rotaries since i was 20 ;-p and fancied a change and the is200 caught my eye and absolutely love the car. just need a little more power :-)
