you honestly make no sensefor less than 500hp then srp. more then JE or others my bro got some piston, srp stock bore size for 200 (b16A). let me know.
but...srp is cheaper than JE just for the cost fact.
ah ok...srp = je. but je can handle more hp than srp.
na...stock axles are good for like 500-600hp...ack 400whp = crazy insane for street...you might break alot of axle
