Need porting advice
I'm going to be getting a little crazy with this engine ..
I know im going to port, just gott figure out how far to go
Because of budget , I have some obvious limitations, but heres what i have to work with:
N/A of course. I have both S5 and S4 blocks, manifolds, etc
I'd like to do porting for that extra oomph with this rebuild but I dont want to have to spring for too much.
I need a port that will keep the powerband in the usable range, I don't want to have to buy lightened rotors just to run the port
I might be willing to spring for some hardened stationarys if tis necessary.
So, streetable 6 port with not too outrageous powerband . I'd like to have 200-220 at the wheels . I won't have to pass emissions so i dont care much about that.
So ideally, what's the best port to run on stock ECU maybe S-AFC added on and stock intake and gears/rotors?

I dont think a streetport would get you there. Ive seen a few guys go with street porting the primaries and secondaries, then a small bridge on the auxilliaries. But your not going to run anything like that without the ability to tune the timing map. But even that port may not get you there, ive started on my "1/3 bridge" but havent got the dough for the rebuild kit yet. Im shooting for 200whp and i'll get a header, and an e-manage with the timing harness. But with the new additions coming out with the emanage, like speed density and individual tuning of primary/secondary injectors as well as leading and trailing coils i think its a realistic goal. Also, it would be good to use the s5 engine so you can take advantage of the VDI. Im going to give it a shot and do the electric 6port/vid mod. Oh, yeah, the new emanage will have spare solenoid drivers to activate the ports too. This port should keep you in your usable rpm range for the s5 engine as long as you dont go too far. There was a thread about this on TeamFC3s. Maybe later i'll find the link.

Didn't know the e-manage had that capability... i wouldn't mind the few hundred that they cost... are the ignition controls compatible with FC's? Anyone used it with the timing harness before?

Not gonna happen. 220 at the wheels is about 250 or so at the flywheel, and you're not going to be there without a bridgeport.
Mazdatrix sells a 6 port template, though it doesn't massivly change the secondaries. Probably only good for a 25-30% increase. If you want more, you'll have to go past the available templates into some of the "crazier" 6 port porting. I have not done any of these ports in an NA application, so you'll have to ask someone with more experience. But I would imagine that based on their sheer size, they move the powerband up somewhat.

I want it to have some kick in the pants feel but I'm not going to be drag racing so it's not worth it to do anything too drastic.
I guess the real question is do you have any recommended templates?
Of course I might be willing to just ship off the irons to get ported, just depends on the price
