Well..... That escalated quickly.
LOL, well bottom line is its fine- just needs a catch can or intake/exhaust scavenged sump.
Mazda's allowable side seal gap is huge and people have been porting wrong since the 70s damaging side seal corners and the engines run fine.

ok small update, i bought a used Haltech platinum sport 1000 ECU from a forum member, and i pulled the trigger on a Ludwig engine wiring harness.
the plan is to use the PS1000 box until the haltech Elite has rotary support (as the ECUs use the same plug), then just swap ECU boxes and have all of the Elite functionality. ludwig is building me a harness to make this possible
with the elite ecu i'll be running drive-by-wire with a FFE DBW kit (including launch control and cruise control) and several other cool things. the DBW is pretty exciting, but really the main thing i like about the ECU is the long-term fuel trim table, which i was doing manually with my PS1K datalogs via excel pivot tables...
i'll probably have to use the PS1K for 2-3 months until Haltech gets their S together and makes the Elite have timing split.
i'll post an update next week. such excitements!

^ I was curious by what you posted here. I find it interesting and obviously more contemporary to incorporate a DBW but I was wondering how you were going to go about it.
Are you going to run the FFE adapter plate with a GM throttle body? Or, are you going to run the stock TB and run something that haltech sells?
You've perked my interest on the haltech elite series (2500) ecu. It seems to be pretty incredible by what haltech is saying it can do.

i'm planning to use the FFE adapter plate, a GM DBW throttle body, and a custom (or the IRP) oil filler neck.
also, i'm hoping to run the 1500 series of the elite ecu, which is rumored, and would be a slightly watered down version of the 2500 (like the PS1000 vs PS2000).

ok, while waiting on my harness from ludwig i decided to do some small work to the car, including:
re-wrap the charging/ignition harness and re-do the main engine ground
install 850 primaries (stock rail bored for the stock 850 secondaries)
remove FPD and install barb fitting
install new injector diffusers
install new injector grommets for the primary rail to iron
hopefully i'll have my nice ludwig haltech harness this week and i'll do a nice update next weekend
here are some pics.

that is 3m friction tape (3m # 1755) i got on amazon for like $2 a roll... it's great stuff. it's really not necessary, but i thought it looked nice. i'm not sure what other benefits (if any) friction tape provides. i know most high quality german cars in the 90s used it on all their wiring harnesses though.

There were no broken wires or anything, but the main ground wire was in pretty bad shape on the engine end. And it was bolted to the engine with a little m6 10mm bolt, onto a painted iron.

i did a little piddly work tonight; i made an aluminum bracket for the GM 3 bar MAP sensor and mounted it to the UIM. nice and clean.
not as nice as AX75F92's bracket, but it'll do
nice little straight shot vacuum line for the MAP sensor

I need to copy you on a few things, and now is the time while the motor is going back in. Namely the primary rail grommets and redoing the charging harness. Just longevity mods really, lol. One step beyond reliability mods. hehe Why did you remove the FPD since you have the ability to keep it?
Also, why the switch to DBW?

i removed the FPD because the modified primary rail i bought (modded for 850cc injectors) already had it removed. i didnt want to go through the trouble of removing the FPD from my previous fuel rail and installing it onto my new rail.
also, running DBW gives you the ability to do some really cool stuff, like cruise control, idle control, traction control, launch control, etc. this also allows you to ditch stuff like the archaic BAC and the cable-type cruise control actuator, which will free up that driver side firewall corner of the engine bay.
