I think I may go with 740s with 300 degree rails now instead of going with 555's.. However i will be running them with stock turbos for a while.. When i upgrade intercoolers.. say Z1 smic's.. and i run the 740's would i safely be able to run say.. 19-20psi?? but that is getting out of the range of stock turbos correct? Or is that where meth comes into play.. I plan on going the Z1675 turbo route eventually.. My goal is a 550-600 street Z -George
