im building a N/A 12.5:1 compression motor with k20z1 head and k24a2 case for my s2000 and i need help deciding between brain crower 102mm and drag cartel 106mm crank shaft , im going to be running a 88m bore , are 106mm way to big ? is it just going to tear the motor apart ? i noticed BC stopped selling there own 106mm and is it because there to unreliable/way to much stroke ? il be using a s2000 oil pump, whats a safe red line for the 106mm or 102mm ?

any other pros and cons between the 2 crank shafts would be great too, thanks for the help in advance
