No idea.
I haven't had it dyno'd and it needs a retune because it went to an electronic boost controller (greddy2), just before i purchased it.

It's my daily, but it's the 14" wheels, 2" muffler and fuel setup that's holding me back before i get a re-tune.
Just been doing my routine servicing, has served me well over 3yrs and has started every time so far!

I am doing my apprenticeship, so thinking of building a b16a in class and just bolting on my kit since the manifold was designed for a bseries. Which would explain why i don't hit full boost til 4.5k.
