Doing a complete maintenance job, what else am I missing?

[NSX-ST]

I have a 1995 NSX-T with 38,000km (~24,000miles) and need to do a timing belt job. While I'm in there, I plan on doing some preventative maintenance and have come up with a list of parts to replace. Please let me know if I have missed anything or have something on there that doesn't really need to be replaced just yet.

Air Filter/Fuel Filter/Oil Filter
Spark Plugs
Timing Belt
Tensioner
Waterpump/Lower Timing Belt Cover (97+)
Valve Cover Gaskets/Spark Plug O-Rings/Valve Cover Grommets
AC Belt/Alternator Belt
22 or 23 Hose Kit
Crankshaft Pulley
Oil Pan Gasket (sweating at the moment)
Valve Adjustment
New Fluids (motor oil, tranny, brakes, coolant)

Do you think I should get these as well for more protection?:

SOS Locking Timing Belt Tensioner
Timing Belt Shield (from titaniumdave)
Coils (do I need them yet?)
Injector O-Rings (read about fires?)

Thanks!

Timing Belt Shield (from titaniumdave)

If you go with this you may can cancel the pulley.

Sounds very good, I have nothing to add just maybe: did you have a look at the cam plugs?

EDIT: Behind the crankshaft pulley there's an o-ring, p/n is 91212-PR7-A01 for a 91.

I would do the cam plugs while you're there.

How often does the crankshaft pulley fail (center part falling out)? I guess I could change the pulley out quite easily if there ever was a problem. What goes wrong with the cam plugs? Rust? Is the O-ring an upgrade?

The harmonic balancer fails seldomly AFAIK but if it fails... I've read of about 3 or 4 failures. It failed on my friends car and he was VERY, VERY lucky. From what he said: your engine doesn't have 60 miles without the shield. The shield gives you much more time/miles to react and you hear it for sure. Changing it afterwards is done within an hour (with the right tools ).

Cam plugs -> oil sweating or leak

o-ring -> oil leak, if you're doing the head cover gasket you could/should do this too, it's cheap and is done (only!) best with the TB, it's a 5 minutes-job.

Good luck!

Magnetic oil drain plug if don't already have one. Look at your CV boots for very slight leakage especially as the left side requires a tranny flush which you are doing anyway. Of course, look for minor tears in the boot too.

I've always wondered if those magnetic drain plugs really worked. I believe my passenger side is leaking on the inner side, which I think is causing a clicking noise that is speed dependent. How will I know to change just the boot or the entire shaft?

Clean out the throttle body.

When they do the brakes make sure they do the ABS system also. Check the clutch slave for leakage

Some people like to change out all the hoses.

Don't wait to fix the CV boot, I waited too long and had to replace the joint. Makes a difference of $400.

Search around, but this thread is a good resource. Tells you the tool you'll need to fasten the bands around the new boot.
