B18C2 Type R Cams and Springs, plus I/H/E in an EG. I used to get 490 from 40 litres, and then I had to put a quieter muffler on the rear, to quieten the car down, and stop the drone from the straight through exhaust. Now I get about 400, very disappointing, but much easier to live with day to day. Power has also dropped from 125 at the wheels by 10% IMO.
