the rb20 wont rev up to 10k very easily unless its fully built, stock the limiter is at about 8 grand i think

 

i like ca's i dont think there bad at all considering they have forged internals an a steal head gasket. an stock u can run em on about 25psi all day an not hurt it . i just wana keep my rb an the rev limiter is 7400 for mine but thats depending if its the black or silver top . an they do look the same from the front...i think
