Boost levels i guess I will be playing it safe ish at the start about 9-10 psi ?? Just want to lower it a bit until I get forged internals .. The turbo I'm using is the td04 19T don't know how much bigger that is compared to the 16T .. I guess I'll just stack two together and see what happens .. Trail and error basis I suppose ??
Also would you use sealant when stacking head gaskets together ?? Or just stack em and the clamping load will seal it up ??
