should I bridgeport or streetport?
hey guys I'm in the process of building an engine for my s4 TII. Im a little undecided on which route to take if i should go with a large streetport or if I should go with a bridgeport. which route should I take for more and easy HP and running lots of boost. this car will be driven to regularly not my dd but it will be used every once in a while and will also be used at the track so I need something powerful but at the same time reliable and durable. I already purchased all the stuff to close the engine SCR apex seals and springs, original side seals and springs, atkins solid corner seals, original 93 corner seal springs, original O-rings and springs for the rotors, new original bearings and the original master rebuild kit you know gaskets and coolant seals and all that other crap all i need is to do the ports and close the engine so i need some advicing from you guys. once i close the block and start working on it i will start a thread to share all the fun with you guys
thanks in advance.

Peripheral porting decreases engine life significantly.

A p-port is better than a full bridge, but it may be expensive to rig up.
The 787b ran an NA p-port instead of a turbo for reliability reasons. And it's engine was still in great shape after being battered at Le Mans. OTOH it also got much better gas mileage than the pistons racing (and PP's have horrible mpg), so maybe that's not saying much.

False. Bridgeports make more power across the entire powerband due to making the turbo spool faster.
A bridgeport will reliably make more power across the entire rpm band, all else the same, just as reliably. The only determining factor is idle quality, and putting up with the annoying BP sound.

They don't. Turbo engines are 4-ports. Aux BP's are a waste of time.
