Half bridge 6 port

Car is an 88 GTU.
Im ​​​​​​ running an rtek 2.0 for fuel management
Porting will be a combination of the pineapple street port and mazdatrix half bridge with a EP2 exhaust ports. With 2mm fly cuts in the housings. D porting the irons, and really opening up the intake tract im machining solid dowels, I'll be using a steel lightweight flywheel. Modified Atkins aux sleeves "altered for the bridge", and a ford lumbar pump activated via rtek to control the aux ports. I'll try and keep this updated as I go, I should have my housing and new apex seals back from goopy later this week.

What are your power goals for this? I have a 6port I about to either Bridge or try and 4port Irons and bridge those. Its not super easy to find a lot of information on NA performance. I really like where your build is going.

I'm not really shooting for peak number per se,.although it seems like 230 whp is the number to beat. I'm more interested in torque and power under the curve I'm building it more to be a fun streetcar That I can take to the track or autocross with That just has gobs of power where you want it and not Some peak number .

Well, since it's another wasted weekend waiting for my housings from goopy, I put the keg together with junk housings to start building the lines for the oil bypass and fuel lines

solid dowels because why not, it's only going to help support things, and it will probably end up boosted at some point, so it's just preventative maintenance.
The external oil line is just fine with -6 line, the port itself is only roughly that size anyway, and bypassing the two 90 bends and turbulent dowel threads alone flows better.
