Ej 25. Non Avcs 2l heads relieved to 99.5mm. 26cc piston, 51cc chamber. Cams to suit 2l non avcs heads.

That cam has -8 degrees overlap @ 50thou lift. It basically sits now with 0 overlap @050 which gives a small amount overlap @40thou lift. Around 2-3 degrees I measured between 040 and 050 lift each side of the lobes.

Ok so now I have built a 2.34 with +2mm rods. I will be running the bc 280 cams with the exhaust adv 4 deg. I will be trying the Blouch 3.0 xtr. I will let you know how the torque curve looks this time. It is also in a forester but this time with a 6 spd.

Any updates on this? Im planning to replace the stock plastic exhaust cams on my11wrx hatch. Im in the process of a build. Ive had a stock cam gear explode on one of my other scoobs so Im doing ti more for insurance then for the adjustability.
