Which porting template would you reccomend for the 6 port? Intake and exhaust. I am looking at either Mazdatrix or Pineapple Racing. I tried to search alittle but most threads seem to go down the 6 port is junk path. I am rebuilding on a budget and have a spare set of 6 port irons so switching to a 4 port is currently not an option. I am just looking to do a street port. Currently running the stock ecu. Would like a Power FC or maybe an Rtek one day with a goal of 200whp, but that is years down the road. Thanks.

 

Rob at pineapple said you can get 195 out of his ports without a standalone. That's on s5 rotors tho. I've heard of a few people up in that range on stock ports with standalone only

 

Do you know if that is using a S-AFC to adjust fuel? My car is a S5 so that sounds interesting. I am kinda on the fence as Mazdatrix is cheaper but with Pineapple the ports are already cut out in the template. Both seem to have experience and know what they are doing.

 

I went with the Pineapple Racing ones. Partially because they are already cut out. I also did some digging around and if the pictures I found are correct it looks like they don't close the aux ports as late as the Mazdatrix ones. Looks like the focus more on the secondary and have a thinner bridge between the two but still don't combine them. I didn't find a good comparision for exhaust but got the EP2A medium one.

 

I'm in the middle of building a clone of judge itos bridged 6 port if ur comfortable porting give it a look he made 230 with the stock s4 computer nopistons.com he also has a vid on YouTube.. hope mine works just as good all motor

 

I used the Pineapple ones and expanded a little on them, made 184whp on a worn out S4 keg, while running out of fuel when I first dyno'd it
