Hey Def, you seem to have a vast knowledge of 240s, do you think for my application (mid range 350-400 whp), the 7163, or the 6758 would be better suited? I have a notch top, Tomei Poncams to keep VTC. Front mount, full exhaust, 340 fuel pump, 740 injectors. I will use 91 octane with water/meth or straight meth. I really like the idea of twin scroll turbo/manifold. Do you have thoughts on raising compression ratio slightly to 9 or 9.5? I like the idea of a stroker kit but 3500 is a lot of money on top of the turbo/manifold/downpipe set up.
