my fan and shroud came from sneed speed today, got it with a heavy duty relay and thermo switch.
I had a v-band welded on my turbo, and a 1/4 hose barb welded onto my 2 stroke oil resevoir.
I also had a bung welded onto my waterpump housing for my temp gauge. This is really the way to go versus drilling and tapping
the housing itself. I ended up using one of the un-used water passages that would normally go to the intake manifold.
The other one by the lower radiator hose was also welded shut.
I mocked the Himni downpipe up to the turbo for a pic

Rob, just adding more info in order to be accurate. The throttle body is 1/2 the picture here, the upper and lower intake manifolds are probably more of the big picture.
I was at JR's today, we did another oil change on the 7. He pulled out a Pettit "high flow" throttle body that is sold on his website and came in on a customers car, it is somewhat similar to what JR is doing. Except when you place it against the upper plenum you see a ridge around the entire throttle body where it meets the plenum, the plenum iss now too small, JR does a lot of porting of the plenum as well to port match them together then to clean up the airflow allowing no resistance through the entire intake plenum tract both upper and lower.
Like I said earlier, the result is 50 more RWHP which is a HUGE gain from a single passive modification. The untold story here is the low end torque we are all seeing (or should I say feeling) from this mod. I took off in second gear the other day and did not slip my clutch nor nail the gas. I also noticed a lot more low end grunt from the car.

NYE I finished up the gauges, I ended up drilling 2 new holes in the firewall and using grommets so I could run them better.
I also ran stainless braided line for the oil temp gauge.
Drained the gas and put some super unleaded in it, figure Ill get one more easy state inspection then the motor comes out.
Hopefully by next week the motor will be out and the drivetrain swapped, we shall see what happens!
Cant wait to get the rebuilt drivetrain components in with all new mounts.
Side note- damm my undercarriage got abused this last round of it sitting. The car sat for about 2 years in my "garage", the undercarriage is going to need some cleaning and detailing- Ill leave that for another thread because its something I HAVE to do.
Think I will have new concrete poured in the garage and run a de-humidifier all the time.

Hauled the rest of my parts away today, and the car itself.
I know that the little things is what takes time on projects so I anticipate a few issues here and there.
My rebuilt transmission and rear end in the back of my truck for the ride.
the sun was getting low in the horizon, so off I went, car in tow.
turns out we had that bracket on there not realizing it will no longer be used, it looks pretty on there though.
stay tuned!

well we had some set backs between schedules and some part tracking down.
Ends up someone along the lines changed the front cover on my transmission, which we did
not realize until we went to put the throw-out bearing and fork on.
was a little bit of a bummer because I have this custom clutch set up and did not want to change it.
So a quick $45 part and some aggrevation over the way Mazda sells thier **** and the problem was solved.
Funny how they list ONE front cover for all transmissions, but they list 2 different bearings and forks hmm?
Luckily everything is interchangable beacuse it turns out I had a s4 front cover, and the trans is s5, so the mounts
are all s5 and what not, but man when it came time for that bearing it threw us for a loop!
My theory is that because this transmission came from one of the j-spec packages I sold a few years ago that someone
in japan must have blown thier transmission in thier s4 car, went and got a used s5 trans, and to eliminate having
to change thier stock clutch set up they swapped front covers, who knows- maybe they had a brand new clutch they did not
want to replace?
anyhow- here are the pictures.
Motor is in, wiring for the wolf has begun. Radiator is not in yet because we are going to change the ac condensor, its pretty ratty looking
and I MUST have my A/C!
We are also going to change some of the fuel fittings as the red and blue dont go, so we are going with all stainless and black AN fittings.
Also going to swap out the engine hook, I have one that matches the brackets and the intake manifold
I know there is some talk about a manual rack swap for a PS car, I had a brand new, never installed manual rack that went
into this car, I had no brackets with it- it dropped right in.
So I believe the issue is putting a manual rack in a S5 car- so if thats the case you dont need the manual brackets- you can go with
any s4 brackets.
If you peek by the OMP you can see the aviation adaptor that meters 2 stroke oil into the motor via throttle linkage.
