pistons are wiseco. they are quite low comp pistons, with a zep 1.2 mm headgasket. the ported and polished head has obviously helped bring the torque up, and ive made the boost pipes 51mm all the way around to help with torque/lag.
not sure on afr yet, ive got an AEM wideband gauge on the way so we shall see. it runs 1.6bar and doesnt really drop off at all, to be honest its quite tricky trying to look at the avcr once its on boost lol i was planning on running external wastegate but the hks actuator seems to be doing a good job of maintaining steady boost so wil leave it for now.
il try get the graph up over the weekend
