If you are going with a built motor then that means you will have to run more boost pressure to get the same HP due to lower compression, unless you are keeping stock compression. More boost pressure means more pressure drop against the deadend rail. I would definitely upgrade to one of Phunks return systems. At minimum I would go to the S1 return setup. Whether you want fuel rails is your call. Phunk is the expert so I'd consult with him.
To be honest just for my own comfort I'll be upgrading to the S1 system at some point its just a few items down the list at the moment. Seems like I've been upgrading/repairing/spend more money than I have been actually driving and enjoying the car. It's time I stop tinkering awhile and get in some serious
