I wanted to use forged internals with the b16b block but they do not make aftermarket rods for my case so i had some thinking to do... I found out that a gsr crank, pistons, and rods would work perfectly in the motor so thats what i did. I went with Scat GSR rods, 82mm Wiseso 10:1 compression flat top pistons, acl race bearings, cometic headgasket, oem oil pump, water pump, timing belt, ect...
