The stock motor will take 400 hp but I wouldnt be boosting 23-24 psi on stock motor, its like testing its limits.and the turbo's too.and for what?
keep it safe till you do some supporting internal mods, and decent tune.also you need a external waistgate to be able to boost that hi on the 2871
I would do 19-20 psi max on it even if done right...just because someone else made 400hp on stock motor doesnt mean your motor will hold up.
