once the motor gets swapped it will be a track car.
Crank is damaged from the spun bearing so I can either get it resurfaced or just get a new one.
I would recommend regrind, that way you can get everything machined exact and there isn't any wear...
but some people here are going to recommend getting a new crank, because they don't believe that crank regrinds are possible, lol
Just get a new one. Trust me.
I know nothing about either motor, but wouldn't the I-6 have more potential?Ahhhhhhh for now I'm stuck between 2 motors.

I6 ftw, goes to the "no replacement for displacement" bit. Almost 50 ft pounds of torque right off the bat, and every upgrade from here out will yield a greater amount of power vs the 4 banger.
Indeed. The L6 will be a more useful engine. More fun to drive too.I do like how the I6 has max torque at 3200 and max power at 6400. nice broad power range.
Yeah, me too. The L6 will be much more fun to drive. But if you're going for an RB, why not a RB25? They cost about the same, and there are more parts available for the 25 than the 20. A RB25 can make 300 with a boost controller and retune.I would go with the I6.
