I'm going to purchase an Rx-7 pretty soon, but the one I'm looking at has a bridgeported motor and pretty much is a racing car from front to back. All I know for bridgeported motors are that it sacrifices low RPM's and smooth idles for a High rev engine that has more power (Correct me if I'm wrong.)

Since I won't be hitting the circuits anytime soon most likely, is there anyway to convert a bridgeported engine into a street ported engine? (A bit of a downgrade, but oh well.) Or can bridgeported engines run on the streets just fine?

 

It's not possible for an engine that has been ported be converted, but if your looking for driveabilty go with the street port. The bridge port engine are known to have a short life span.

 

I reccomend you find someone in your area that has a bridgeport, and ask them to take you for a ride.

You should know by the end of the ride if you want a bridgeported car or not.

 

You cant converet it, youll get shittyyyy gas mileage, have to idle nice and high, shorter life span, but itll kick *** on the track...hows that?

 

You are looking to buy a street car. The individual car you are looking at is a track car. Do the math. Look for another example.

 

Thanks for the information guys. I think I'm just going to go with another FD I found. Hopefully, I'll attain it within a week or so. And by the way Rynberg, although I did mention it was a Racing car, what I meant was a Track car. Sorry for being so vague. I had no idea Bridgeported motors had low drivability, hence, I posted on the specialty forum. Rx7club.com. Thanks again guys.

 

you can epoxy over the bridge, but you can also just pop a new engine in there. but i think you'll like how the bridge feels.

the low rpm issues with a bp are more for n/a cars. the turbo spools faster with a bp and kinda evens itself out. they are totally drivable. i daily drove mine until it was stolen, and it got 19-20mpg on the freeway.

 

I love my half-bridge motor, sure it idles high (1300-1400 rpm) but it spools up my GT42R quickly.
