What do you guys use for a temp gauge assuming you use one? Do you use an after market gauge? I'm curious what gauges/sending units people are using. Pics would be cool if you've got them. I would like to keep the old school look in the interior as much as possible.

Thanks,
Jay

This is what I use but I don't think they have the 'ol school look your looking for but would work nice on that new Subaru engine.

Albert, Thanks for the link. I suppose I could use about anything for a temp gage really. I would like to steer clear of digital though. Even if it looks newer style, it's got to have a needle, for me anyway!

Jay,
I'll be installing Autometer gauges in my GS.  My 2.0L turbo motor had a couple of senders in the crossover water manifold on top of the long-block.  I'll be retaining one of them for the ECU, but the other one I re-tapped NPT for a standard gauge sender.  It was a simple operation to re-tap the manifold - though it was removed at the time and easily cleaned out of chips, etc.  Did the same thing with the heater hose outlet on the end of the manifold so I could use a standard hose fitting in that location too.  I've forgotten the NPT sizes I used, but I can check if you need the info.

Once you have the sender location set up NPT, you can use about any gauge type.  Alternately - If you're thinking VDO gauges I'm pretty sure VDO has some senders that might thread directly into the Subaru manifold/fitting.  I "think" it was a straight metric thread and sealing copper washer type fitting.

BTW, the oil pressure gauge is the one you need to be worried about!  The fitting in the block for the OEM gauge can also be re-tapped 1/8NPT (which is what I did - again after removing the fitting from block) - but the room above the fitting for a large sender is minimal!  With the alternator and stand sitting just above it could get complicated - though nothing that a 45* or 90* fitting couldn't probably solve.
Depending on how you have the engine plumbed for PCV and crankcase venting, there's a 2nd block plug towards the flywheel end that could be swapped with the pulley end plug/fitting.  That would move the sender next to the bellhousing.  I've maintained the PCV system so that area is full of hoses and tubes on my engine!

There was some discussion about other alternatives for oil pressure sender location - check the other threads.

Installing all these senders - pre determined for your gauges - would be something I'd handle before the show!
You want the install to go and appear as easy as possible!  LOL

Jeff, thanks for the info.
I'll have to work out the details with Paul later on.

I have found a source for metric adaptors. I wish I knew what thread the engine is.

I decided it was going to make more sense to ship the sending units for my gauges to Paul and let him deal with adaption to the engine, since he will have the engine in front of him.

Paul, if you are reading this, I'm hoping to ship the oil pressure transducer and water temp thermocouple out ot you on Monday 2-11-08 or Tuesday 1-12-08.

I'm finally reading this... I did get the sending units. They are laying on top of the engine right now.  This will be interesting to adapt the metric fitting to an NPT and possibly back to metric for the idiot light.  Maybe we could use the second location for the oil pressure sending unit and leave the idiot light sender where it is.

Paul, whatever is going to work the best is just fine. With tiny little items like these sending units, I'm not going to get too anal about how it all goes together as long as it functions. The larger items like radiator placement I'm going to be anal about because I don't like the looks of the radiator period.

Again though... function over form. If I have to go with a temp install on the rad just to get it home, I'll live with it and change it when I'm back. I'm also cost driven, so if less engineering keps the price from skyrocketing, then a temp rad install is the way to go.

Sorry for the tangent, but wanted to clarify my thoughts.

Actually - I had flipped this discussion in my mind to relate to oil pressure, not temperature.  I'll check both out and figure out what we need to do.  Paul...
