reasonable expectations for power output stock intake ports

em55ron · 06-23-2012, 06:33 PM

I have a rebuilt 20b that was doweled and pinned by goopy.performance.The motor has turbo exhaust sleeves. My question is, what can I reasonably expect for power output without any intake porting.. I have a BW S475 1.25 a/r to push all. Originally wanted to avoid any porting to see what I could get on the very large intake ports. However, Im now concerned that.i wont be able to make over 600bhp.. Im shooting for closer to 700. Before I put the motor in I want to find.out if im better off pulling it apart and porting it now, or am being unreasonably worried
