After speaking with chuck her on the forum I have decided to go with a thermostat from a 2008 g37 since it opens at 170degrees instead of 180.. Thanks again chuck..

Any little bit helps as hot as it gets in FL or TX.

I'm running it too. Car read outside temp of 98deg this week and it's only April. Gotta love Texas summers.

Just ordered a new Setrab 34 row core and a CSF Radiator.. Between that and the lower thermostat and heat wrap for the tubo's and manifolds hopefully this will address the heat issues in the hot summer...

Make sure your tuner addresses the fan tables. Sam doesn't really do much with them and that probably makes the biggest difference.

i think your outside temp is off man. haha it was warm in houston the last few days, but not 98! not yet at least.:icon14:

Maybe at intake level sitting on the freeway in traffic? Either way it's starting to get hot, dammit.

Mine has histroically run 5-6deg hot

The car ambient temp is always 5-8 degrees higher than what it is actually reported because of heat off the road, exhaust, etc.
Sitting in traffic on the beltway I can see 10 degrees higher than actual ambient temps per the car sensor and I would believe it. Though with my fan speed, CSF, thermostat, vented hood my water temps stay at 200 and peak at 208 now in full traffic.

i agree in traffic the outside temp will clime on mine too.

Monday I will wrap my turbo's and begin reinstalling the motor. Here are a few things I have waiting to go in and still waiting for my setrab 34 row oil cooler and thermostat..

Anyone happen to know the torque specs on the flywheel and clutch right off hand? After I get that back on I will mate the tranny and get that thing in the car...

Both of these are for my 2010 G37 but the clutches are the same

Thanks man!!!

Got my turbo's/exhaust manifolds wrapped and new thermostat in yesterday. I'm just about to get it off the engine stand so I can install the clutch and flywheel. Thanks again for the link..
