He beat the piss out of it? how do you figure? If your motor's going to show any signs of weakness it will show up on the dyno. I blew 2 motors on a dyno.
My 350Z has at least 50+ dyno pulls from a single day. over and over and over again.
What power were you making with the B16? what fuel setup do you have, what manifold, what exhaust? how big? open or closed dump tube?
I had darton sleeves, custom JE pistons, I think eagle rods. honda OEM crank/bearings,ARP head studs. after market GSR oil gear. OEM valves, with after market springs, and retainers.
How many miles did the motor have?
