Work stock 12 valve
#2
thats going to depend on the org that you pull with, i have even heard of some places allowing up to 64mm S300 chargers. so i would dig a little on their rules maybe even post them in here. but we can do some interesting stuff in a "stock appearing" housing, just finished one today for a dmax and its closer to 2.8 but its stock appearing and plugs the stock 63.5mm bore
