I am going to have my engine rebuilt this spring by Rotary Resurrection, and I was wondering from you guys what porting I should go with? He does Aux. Porting, Primary porting, All ports and removes exhaust sleeves and cleans them up. I am wondering what you guys think will give me the best power gains without sacrificing lowend. Mods that are done to the car are as follows: Cold air Intake system, port matched the manifolds, 5 & 6 Pineapple sleeve inserts, Racing Beat streetable header, Magnaflow High Flow cat, Borla cat-Back, and Mazda Racing short throw shifter. I also have a SAFC installed on the car that will be tuned after the engine is rebuilt and the break in period is achieved. I am looking for good high end power, and trying to get some low end torque out of this as well. Here is the website with hte options on it; http://www.rotaryresurrection.com/2n...ne_prices.html

Thanks for the help.

OEM seal kit .4mm advance on P and .6 in S. 1mm exhaust close.

 

Could you explain this to me, I am not exactly sure what you mean by this. Does it mean advanced the primary port .4mm, and .6mm for the secondary port, and then open the whole exhaust up 1mm? I have never ported before and dont know exactly how it should be done, but the .4mm and .6mm seems alittle small to me? Could someone explain to me why this is?

 

You understood exactly.



Bigger is not always bettor.

 

exactly, stock intake is the limitation with the stock ports...

 

Hallelujah!
