I searched here and in the build section and didnt see an answer so ill ask here.





What are the power gains associated with the different porting options on an NA 13b fb5 engine? Streetport, large streetport, bridge, half bridge, and the others. The engine is stock right now, and the car has the full rb exhaust. What other upgrades would be necesary to achieve the power level you quote? (ignition, intake, fuel, etc.)



There would also be a lightweight flywheel thrown into the mix, and possibly dlidfis.



Also, there are no peripherals, ac, ps, airpump. Just water pump and stock fan, which may get switched to an efan.



hint: this isnt for my car.

This is for my car.



Ive gone ahead with the holley 600 idea, im goign to wait until i NEED to pull and rebuily my engine before i port, but when i do, im going with a nice bridge by steve kan.



I do have a question for anyone (j9 will most likely answer haha)



i purchased the FULL kit from racingbeat, i had to order the mallory 4070m fuel pump elsewhere, im just curious as to what else i will need.
