hi i just bought a 2nd gen rx7 and i am looking for some info on the motor, the car needs new apex seals and i also purchused a parts car with the atkins stage 2 street port motor and i am wantn to bridge port it so if anyone would like to give me some info on were i could find some templates or the bridge port it would be greatly appreciated

You do realize that you have to tear down the engine to port it correct? That means rebuild.
If the atkins engine is good, why not just transplant it in to your car?
BTW, a bridge port is not an ideal street engine.

Why does the car need new apex seals? Did the PO just say it does?

I don't suggest you bridgeport the engine. A bridgeport is a big jump from stock ports. It would require a lot of supporting mods. If the car is turbo, it needs a full turbo upgrade and all the stuff that goes along with it. If it's an NA, then a new intake manifold, exhaust system, EMS, etc. And it will be LOUD.

yes he said it did plus i did a compression check and it didnt have any, the atkins motor doesnt have any compression either.and yes i no i need to reuild the motor and tear it down to port it and what would be the best port for everday driver/ street racing.
thanks

yes i got a new header with the parts car i just purchused and i no i need to carberate the motor if i bridge port it

Best street port I believe is an extended port. You'll see some power gain and it'll be a bit louder and have more of that "signiture" idle.

I'm pretty new to rotaries, but I believe that even a extended port might need intake/exhaust upgrades.

You need to clarify whether these engines are turbo or N/A.

Also, I could be wrong but I thought you couldn't have headers on rotaries due to there being no cylinders?

If not, i stand corrected!

Also, if i may ask, why carborate for the bridgeport?

Street racing?

Grow up and stop endangering the rest of the population. Sell your vehicle and take the bus.

1. I believe by extended port you are referring to just enlarging the stock port. This is usually called a street port, not an extended port. Just a FYI if you are looking around the boards. This type of port doesn't require any other upgrade, but to get the maximum potential out of it you will need to upgrade the exhaust at least.

2. Headers have nothing to do with cylinders, headers are an exhaust item where the exhaust is designed to have equal length runners from each exhaust port of the engine to the end of the header where generally they are connected. At least thats my understanding of them.

Messing around on the streets is no better. Take your messing around to a track or to an auto-x.
