Engine out, diff off...what extra can be done?

So besides engine mounts and diff mounts.

*Engine mounts
*diff mounts and diff will be cleaned up from corrosion
*engine bay will be cleaned of all oil
* any other bushings that should be replaced now that would be much easier in current state?

Why is the engine and diff out of the car?

Really no other bushings that are easier to get to right now. Fuel filter is a cinch to get to with the diff out, though.

Not sure what you're looking for here.

Replace all original rubber hoses (vacuum/fuel/water/oil). And don't use SAE fuel hose. It's slightly larger and will leak if you don't clamp it really tight. Also a good time to upgrade to dual oil coolers (OEM is fine if it's a street car). If you are still using the original solenoids/actuators, good time to test them (cold and hot). Also replace your FPD.

Assume you are talking internal, but getting more internal, replace all your oil seals (trans-eng, trans-DS, DS-diff, diff-axles). If you have a '93 clutch fork, replace with a '94. 5th gear sycnro? Shift select spindle. The list goes on....

Fuel lines!! Good idea. Also the dual coolers are going to be attached with something other than zip ties from Pettit. A thermostat will be installed also.
Everything else is pretty much new.
* I should check on the charging harness I guess.

Not sure on the clutch fork.
This was an auto converted to manual. I am sure Pettit used whatever fork was laying around. I will check it out.
The tranny is supposed to be rebuilt and supposedly has about 3k miles on it. Like this motor supposedly had about 5k on it....... she was shifting smooth and no issues with 5th or anything else (knock on wood)
looking for external right now.

I will definitely have the fuel filter repositioned!

Thanks Tom

She is getting a new motor and turbos. And the diff is coming off to change out the 3.90 for a 4.44. Just wanting to make sure I don't miss anything simple that I will regret later. Like fuel filter.

just change the filter while its easy, its not like you need to do very often.

this is just a good time to check everything. how are the heater hoses? brake lines? brake pipes? fuel pipes? how are the shifter boots, radiator, cooling fans.

now is the time to touch up any engine bay paint, and or any of the brackets/stuff.

when i put a car like this together (i'm on the 3rd FC), i make sure all the bolts/fasteners are the correct ones, and then it takes forever, but i run a tap in as many holes as i can, and i use a torque wrench on as many fasteners as i can. it takes forever, but end result is worth it. for a torque spec i take the highest number in Mazda's spec and back it off a couple lbs ft

Thanks. I should probably head up there and check things out before the engine install. Definitely all coolant lines are being replaced.

*Differential side seals are inexpensive and an easy install. Especially if you’ve already pulled the half-shafts.

Use POR-15 to paint the Diff housing, Hangar, and PPF.
Consider replacing your E Brake cables
Consider rebuilding your Transmission and Shifter

I don't think anyone mentioned it yet, but this is a good time to replace the clutch and related parts. At a a minimum maybe the throwout bearing. Those always seem to be the first thing to wear out for me

Thanks for the reply.... I will have it looked at, but they should only have about 2500 miles on them.
in my case I should probably double check though.

While the drivetrain is out, I'd add DEI floor and tunnel shield to the underside of the transmission tunnel. It really helps keep the heat out of the cabin.

Damn good idea.... I haven't had much issue with tunnel heat so far on her, but then again I haven't ran it hard or long enough to know.

You'll want to degrease and clean the underside metal before trying to stick that stuff. This stuff from POR15 is the single best degreaser I have ever used.

Thanks. It will be degreased and pressure cleaned a bit as this thing had oil spew all over 3x. I am not sure if I will get around to the heat shielding the tunnel yet, but I may. It depends on this virus stuff. I may run out of time. Not sure if they shut Kilo down temporarily or not yet.
