depends on what all is needed in your motor.

Well i dont no much really i havnt bought it yet. I had a old one before sold it cause i didnt know any thing that was about a year ago now i miss it and i'm wanting a rotary back. Any ways it'll be a n.a engine with 100 000 on it but the guys not sure... he says it was built at rotary specialties but he doesnt have any reciepts since he's the owner after it was done and he doesn no about the clutch either but ya. I was just wanted to know what it would cost to have a engine say 100 000 on it, and put a bridge or street port?

You can get some huge ass power on a 13b with a large street port or extend port.
Lupe on rx7club is laying down 603 rwhp with a t51r and a extend port.


You do not want a bridgeport for street driving as low throttle inputs are not taken all to well down low with the overlap i believe.


A half bridge can be driven on the street and that involves bridging the front iron and the rear iron and a street port all around.;)

ok so a street port the biggest youi can get or well the one with the best power.

now
you can do what ever ports the biggest gains are made
with exhaust, with out a good exhaust porting does
very little.
the stock 6 ports are very good and with exhaust alone
will make a big gain.
check out the racing beat site i think they have numbers posted there.
