Well my engine is almost ready, my engine builder was kind enough to let me take some pictures of the porting before he put it together.
It has all new parts :-)

Sorry, but I still havent really grasped the concept of all the different types of ports and how they look. Is that just a really f*ckin huge streetport? Because I dont really see it interfering with any of the coolant passages. Isnt that what constitutes a street port?



Someone help me!

 

Hey Jedon!
If you don't mind, who did the proting on your motor?

crispeed
87 Rx-7 TII
9.20@150mph
2600lbs

 

Larry Scott (Independent Honda/Mazda in Escondido, CA) built the engine, he usually makes bridgeported 12A's for rally racing 1st gens.

what's the price range of getting a 13b ported?

 

good luck on getting your engine back in your RX-7.

 

what exactly is a water jacket mod???

 

A water jacket mod is the ribbing you can see in some of the pictures, it creates more surface area for the water, and creates turbulence to cool the combustion chamber.
The porting itself usually goes for $150-400 depending on the port and shop.

Boy, we couldn't reveal that info on the "big list"?

Nobody asked :-)

 

man I want to know what they use to do the water jackets. I have thought about different ways to do it but man those you've got look freak good man. they did a nice job.

 

He uses a die grinder, it is tedious and time consuming.
