NA 6 port half bridge build (zenki FC) - Page 2

Hello all.. so my original motor blew a coolant seal in winter storage (-45 below @ 96,xxx) a few years ago.Im second owner bought with 70,002 miles with all records including all oil changes, gas fill ups, you name it. Even got the window sticker and dealership brochures.Chassis is tip top.A friend of mine gave me a new(used) motor. It lasted 800 miles some how... seized on start up.

This is my only pic of it now(My gf doesnt know how to work buttons)

This is how its suppose to be (exept this is an SE)

So now i have started a rebuild on the stock engine(I think she got mad at me for tossin in a used motor).

I should be able to re use the hard seals. But im not sure about 3 piece seals on a half bridge. Any insight? Im not sure they are even 3 piece but i am assuming so because its an S4

Im trying to run a stock ECU as judge ito has done it and I have seen how fast it was(RIP)(youtube)
To my knowledge he ran stock primary inj @460cc and S4 turbo secondary@ 550cc

I have found no more info as of yet, I PM'd him tho

Mods so far i have done 20k miles on this setup to try to learn chassis dynamics and polar movement at the limit of grip with low power
Tein drift spec coil overs 8kg front 6 kg rear (too stiff)
AWR chromoly lateral rods
AWR rear control arm spherical bearing
AWR camber links (didnt break :0)
Racing Beat DTSS eliminators
Poly bush A arms
Racing beat sway bar end links
AC/PS/smog delete (finding elec pw steering pump)
CAI off a ford diesel (still not enough airflow)
Hawk Hps+ pads (suck)
Short shifter
S5 tranny
S5 tails

Stuff im adding while i build(Already have, or free ish)
I have a full stainless dual roadrace setup im running paralell for about 113-118 inches( not sure how to tune this yet)
Mazdatrix heim joint endlinks
Mazdartix bumpsteer/angle tie rod ends
Tanabe Sustec strut bar
Stich weld
Chassis/engine harness diet
Sound deadening removal (keeping ugly maroon interior cus it makes my tornado grey silver look PIMP)
S5 bumpers and trim(keepin it black)
Shimmed LSD

Stuff Im adding later
Adjustable sway bars
Heim joint ball joints
Full cage and Huge diet
Fuel cell and auxiliaries to support
Urithane stiffening foam
NA Rtek?
Gilmer belt drive
Crown Vics
Downforce?
80s Boatflake gunmetal paint?

K so enough of all that, gettin down to business.
Can i use stock ECU and 3 piece seals?
Would switching the direction of a worn in apex seal with corner piece towards the center iron mess stuff up because it was bedded in rotating the opposite direction?

And finally does longer piping (118") boost low end or high RPM? Or shorter (113")
Im shooting for a Helmholtz resonance effect at around 5500 rpm
Anything else? AFM mods?
