im thinking of a street porting, any one have any experiance with mazsport, or maztech in tampa. Any other suggestions welcome

 

If I'm not mistaken, they didn't make porting on this engine very worth while. The way the ports are shaped and such...you won't be getting a big enough bang.

Correct me if I'm wrong, though.

 

Doesn't work to well with the MSP because you hit the water jacket before you get anywhere.

 

you can also remove too much material causing issues with the seals.

your intake ports are already as large as ported rx-7 engines. exhaust is the only thing you can change, but you can't change enough to make it worthwhile.

only exception is if your engine is already apart and you want to round off some of the edges a bit.

mazda spent quite a while looking at the exhaust ports since they're redesigned from previous rotary engines..

 

There's a reason the same sized engine is pushing that much more hp...they already did some decent ports.

 

thanks for your info looks like fi for me

to answer your question, if I were to do the porting myself using the sand, I would use the coarse sand.

again, not responsible for any damages from porting the car with sand

 

Damages? What damages? *Pours in sand...*

*Car begins to explode*

 

Well, you could always just bore THROUGH the water jacket and build a bigger water jacket around the block for ultimate custom power.

 

course it is, after taking the intake off would you then force it through with a 150 or 200 shot

 

I've only gone with a 55 shot so far... dont want to get too crazy and blow the engine.

 

can i offer peace offering i realize i was being an a@@ that night. i just want to mod my 8 and am thinking of different ways other than just throwing a turbo on it

 

cobb AP
full exhaust
intake or CAI
you can start there or if you track your car then you can look into various suspension upgrades.
