look for a chevy smallblock thermostat, 54 mm. they have 160, 170, and 180 deg, at the napa store. you may have to make a small hole for the air bleed.

I know AutoZone has a 180-degree thermostat listed in their system for these cars (that's where I got the one for my 1986 Subaru RX)...don't know if they list a 170, though.

...and the 180-degree one I got from AutoZone had the "jiggle valve" thing as well. :)

Do you have PepBoys in your area? On the original EA Performance Page that is where the author recommended. I went to 160 with my old BRAT with zero problems. Remember, the t-stat is not perfectly round like most.

don't go too cold, your engine will never heat up and you'll have a lot of unburnt gas washing your cylinder walls, you get at most a half a hp, if you like winter heat and longevity, stick with a 180

You might try an old hot-rodder trick: Use a regular 195 thermostat, but drill a 1/8" hole in the flat area.............this will bring down the opening temperature about 10 degrees or so. If one doesn't do it try a second hole. That ought to make a 195 'stat act like a 175 unit...............don't drill more than two holes, or the coolant will go through to fast and winter warm-up's might be tough; along with a weak defroster as a result.

I have done this with several different engines, but not with any that are computer controlled.........too low a temp in the cooling system and the ECU might "think" your engine is not warmed up and keep dumping extra fuel...........this may lead you to believe you now have more power, but in fact; you'll just use more fuel and wash-out your rings.

Internal Combustion Engines need Heat to make power...........most designs are set up to operate as close to the "overheated" threshold as possible...............A Lexus V8 uses a 198* 'stat...............that's right, 198 F. This is so they can achieve an optimum operating temp. of about 202 F. Cleanest burning and most power at this temp............leaving a little room for triple-digit weather!

At only 85 HP and 100 lb.ft. of torque, the EA82 won't give much more without some serious mods...................maybe it's time for a Turbo............
Otherwise, just drill a hole.

When in doubt, stay stock on the 'stat.............
A two-row radiator is nice and not expensive...................and the heater still works!

Careful. Some guys get nervous when the term "hotrod" and Subaru are used in the same sentence.

Well, SBC t-stats were mentioned above in reference to parts availability and temperature selections.................

I am not trying to connect HR's with Sube's in any way......................but it is possible to HR a Sube...............

Don't you think Bugaru's car is a HR?.................;)

In the end, an engine is an engine; as long as we are talking about ICE's.....

If the mod I suggested seems to be way out there, just ask around. I am not the first one to try it and surely not the last.
If it doesn't work, go back to the stock T-stat.

Erik R, I like your common sense approach.
