Stark Performance Automatic Transmission Cooler Kit

[phrosty]

Will the thermostat work well at -20 degrees? Looking for a mod that'll keep me cool in the summer and not blow up in frigid winter.

Man, that's cold. The thermostat will work at low temperatures. Since some of the fluid does flow out to the cooler, however, it will take a while to come up to temperature in really cold weather. Then again, the rest of the fluids in the car will take longer as well.

It's pretty rare but last winter Chicago got down around there and FR-S kept ticking

The thermostats are now available and in stock. They are modified with new high temperature wax motors with the fittings installed and pressure tested to ensure a leak free installation.

BRZWORLD did the install, of a nice piece of kit. Went in simply and quickly.

Driving sensation, marvelous shifting, paddles are faster, better than when the car was new !

BUT - I did a complete flush of partial ENEOS tranny fluid as well, to a complete fill of new ENEOS.

For an exhaust grate remove the plastic grate (removable access plate) on the bottom right of the bumper bottom plastic plate, orient the slots for water runoff and rivet it into the wheel well. The new hole on the bottom of the car adds more airflow in, or u can order a new plate from stealership.

Cutting out the fog light space invaders plastic is a must.

The new thermostat is not, but then you would have to block off the intake grate in the winter.

I'm ordering the thermostat, in case I ever have to drive it in winter.

All in all very happy with the kit and install.

Will post more after I track it hard.

This is great! Price is also amazing. Wish the paddle shifter extensions were cheaper and more reasonable like this!

I'm glad to hear that the install went smoothly and it made a positive improvement in overall driving experience. I look forward to hearing about your track experience with it installed. Do you have a way of monitoring transmission fluid temperature? I know that the Torque app for Android devices can do it with an OBDII dongle.

Unfortunately OBD used by OFT to monitor engine oil.

The auto tranny in manual mode, will revert to auto while in manual when the fluid is overheated as on a Gran Prix track, in high summer, as self protection.

Won't happen with a large 19 row -

That certainly won't be an issue with the cooler installed.

Torque can also display engine oil temp along with many other parameters. I have a Samsung Galaxy Tab 3 mounted with the GT86Mounts setup that works quite well.

I'd like to pair this with the Jackson Racing oil cooler that also uses a Setrab core.

Is there any reason for me to NOT install them side by side in front of the radiator instead of outboard in the area by the wheel well like your current install?

I have no plans for FI due to competition classification.

It can be done, but I fear excessive rad space will be blocked, and the coolant will be overly hot.

With only my oil cooler in front of the rad, I noticed NO increase in coolant temps.

It was stoopid simple to install in front of the rt. wheel, and with Eneos tranny fluid, now with the hot weather, it still shifts faster smoother than new !

Good call on the radiator space. I'm also considering a rad change to something more efficient plus changing the tstat setting.

What is hot weather where you're at? I live in Phoenix and it was 91*F at 7 this morning.

As RFB mentioned, it would block some additional radiator area, but I don't think it is going to be a huge deal on an NA car. The main reason we mounted the cooler kit where we did was to have a shot of it being compatible with some of the forced induction systems on the market.

It makes sense for you to put it there so the front can be jammed with other stuff.

I need to take some measurements, but could I use a Setrab Series 9 15 row cooler instead of the Series 6 19 row? Then the tranny and the oil cooler cores would be the same. The btu/hr is about the same between the two cores, but the psi delta is different.

Now I'm getting all aesthetic and stuff, trying to keep it even.
