After going from stock to Ko4 to GT2871R do out AEB head bolts need to be retorque down? I know the DSM and honda guys need to retorque their heads when they go boosted. I been running 22-24psi lately and sometimes I think i might need to retorque the head due to running 3x times more boost than stock. Anybody?

There is no need but if you want to retorque normal procedure is first 25-55-75 Nm.

Might want to convert those to tq lbs.



IIRC the tq lbs specs for my race ware studs was 20-40-55 lbs/ft, but I will have to dig them up again to make sure.
