Hmmmm, whats your opinion of durability using this parts? a lot of racers here with modified motors for circuit race only, don't use this kind of setups because they lack of durability, the only stroker kit that had lasted with non "oem honda" stuff (crankshaft specially) is the TODA one.
Crower and Eagle, here is very common to see them in drag racing cars, but for circuit racing no, specially the crankshaft.
For example, 80% + the b20 setups here that are used for circuit racing, they use b18c jdm itr crankshaft + 84.5 mm pistons (wiseco mostly) + carrillo rods, all the eagle, crower, and other brands crankshafts have had a engine damage or something. I really don't think any of this brands are "bad" but for I had saw here at the track, they lack of durability, the source of the problem might be; not properly tuned motors, or the rev limit set to high. Maybe you can tell me of success circuit racing stories using this brands stuff internally.
I plan in a future to build a b20 motor, and now in my mind I plan to use a b18c crankshaft + wiseco pistons.
