Bridge Port
 
I was wondering what horse power gains i could get with a BP on a N/A 6 port 13B, with intake and exhaust mods already done. Also has anyone in here ever done a BP on a N/A 6 port before. The reason why i ask is because i hardly ever hear of a BP being done on a N/A 6 port

i dont' think it would be streetable anymore for one reason

Personally I wouldn't bother with a 6-port as a base for a Bridgeport motor, mainly because I wouldn't want the stock manifold, which will become restrictive at the sort of power levels a Bridgeport can produce.. Get a 4-port Turbo motor, and have it rebuilt with higher compression NA rotors and the mods necessary for a safe 9000rpm. Get a Weber IDA lower manifold, IDA-style throttle bodies and the EMS of your choice. Power should be in the 240-270fwhp range depending on porting, exhaust, tuning, etc.

Of course you could have that much power, with more torque, less noise and less money spent by going turbo, but that's your choice. ;)

BTW, whether a bridgeport is streetable or not depends on the driver, not the engine. I know plenty of guys who drive them on the street and love them, but I wouldn't want one.

Don't even think you can use the stock ECU.
Most go carbs or stand-alone EMS.

Yeah, I should've said aftermarket EMS of your choice, but definitely not stock.

Sorry, my reply wasn't directed to you - I was just replying to the original post. :)
