I'm currently upgrading my S5 Turbo 2 motor, and I need a little bit of input on what type of porting I should go with. The engine is being outfitted with a To4 60-1 compressor and an exhaust housing with a .96 A/R,. The engine is going into a street car, but I'm not too concerned with sacrificing low-end as long as I can make it up in the upper revs, as this car will be more of a toy than daily transportation. Is anything beyond a small street port going be usable with this combination? Also, are the Racing Beat templates well designed? I'd like to handle the porting myself. BTW, while I am keeping the stock tranny, I was planning on switching the rear end ratio to something more in line with the new power curve. Any input would be welcome.
