Pulling Engine... What Else Should I Do?
So I'm pulling my motor to replace the motor mounts, fix an oil pan leak and swap turbos.
It doesn't need a rebuild, but I figure it'll be easier then messing with it while still installed and give me a chance to do some much needed cleaning.
That said, what ELSE should I have on the to-do list?
Anything I should retorque? Anything I should replace? Anything I will have access to that is a good opportunity to do something to? =)
Please feel free to throw out ANY ideas you have.

*Replace pilot bearing and seal, and rear main as mentioned.
*Consider re-surfacing flywheel
*Consider new clutch release (throw-out) bearing and maybe a clutch fork if it's original.
*If old or don't know if they've been replaced...new heater and fuel hoses. Especially turbo coolant hoses...way easier to change with the engine on a stand. None are very expensive.
*Consider new plugs, wires and maybe a coil harness. More expensive than hoses but not that bad.
*If you end up pulling the UIM for anything, I would consider silicone vacuum lines with a set of DaleClark's check-valves and having the injectors cleaned and flow-tested. Otherwise I'd leave them alone.

Aw man, you guys are great.
Rear Main Seal is happening - that was the other reason for pulling the motor. Re-torquing the studs is a must - good advice.
Clutch/bearings/FW was also on my radar.
OEM hoses and silicone rats nest will happen - I think I'm actually going simplified sequential since I really like the personality of the car with sequential twins. However, I'll have to look into the DaleClark check-valves.
Plugs and wires are in hand - along with a new fuel filter. You have a part number for the coil harness?
As for UIM and LIM - I'm moving to JDM on both so I'll be sure to check the gaskets.

Stuff that others haven't mentioned.
i would look into doing a fuel pulsation dampner delete. Banzai has a nice write up.
Maybe send your injectors to RC for cleaning.
If funds are tight and you cant get a new harness, I would inspect and tape up the existing with good 3 m electric tape or grip tape.
New OMP lines and washer and you are keeping OMP.
Get new crush washer for your turbo coolant and oil lines.

I love relevant threads!
I'm in a similar boat - pulling motor for maintenance.
Here's my to-do list (a lot grabbed from this thread):
- Install 99 spec turbos (need to remove broken stud)
- Setup turbos for “simplified sequential” operation
- Install JDM UIM & LIM w/ new metal gasket
- Install new motor mounts
- Delete AWS
- Delete Double Throttle Body Butterfly
- Delete AirPump
- Delete EGR
- Delete ACV
- Delete OMP (...and premix)
- Delete Fuel Pulsation Damper
- Fix oil pan leak / install Banzai brace
- Replace rear main seal
- Replace any / all hose with OEM or black silicone (coolant, vacuum, etc)
- Replace check valves with Dale Clark valves
- New crush washer for turbo coolant and oil lines
- Retape engine harness
- Retorque engine studs
- Change all fluids
- New plugs / wires / coil harness
- New fuel filter / oil filter
- Inspect clutch / FW - replace / resurface if needed
- Inspect fuel injectors - clean / flow test
- CLEAN EVERYTHING

Your list looks pretty solid. Whats the condition of your motor mounts? I have poly mounts in stock. Do you have a downpipe already? You may need new turbo and downpipe gaskets. I never like re-using turbo hardware. if you do the next time they come out they have a good chance of breaking. I like the copper -clad top lock nuts from clipsandfasteners.com

All emissions is going out the window - on the kill list is: Air Pump, EGR, AWS, ACV & Double Throttle.

I'd love to have you in on the conversation... but I don't think you're talking about what we're talking about.

Don't think there was a reason to be so smarmy. wstrohm was addressing what I and probably others were wondering. After all, California is pretty famous for emissions. And you never mentioned this is a track-only car which might have even changed some of the answers we gave you.

So far this has been a productive discussion - and hopefully helpful for others (as it seems to have been). I appreciate your input and input from everyone and welcome more on it.
If anyone has questions on emissions - please start a new thread! I'm sure many people are interested.

Well to get back on the subject I agree with adamc and would correct my earlier suggestion to resurface the stock FW. I finally made the change after several years and wish I had done it sooner. Personally I would stay with something like ACT street lite or SR motorsports which is what I got. Still very Streetable and almost like a power adder. In a way it is I guess.

If I were concerned about emissions, I would have started a thread about emissions. But I didn't. I asked a question about maintenance on a pulled engine and 20 posts in - the subject is is changed by a condescending comment - to which I replied, albeit a bit smarty. The idea was to stem that conversation from going further and invite that poster to jump in *on subject*.
