Good, this is desperately needed.
Hmmm... Boostlogic is only a few miles from my house.
The version shown is for manual transmissions only... so it doesn't have the built-in cooler for the auto trans. I have the auto trans... however, I use an external cooler so I don't use this anyway. Maybe this radiator will work for me.
Here's the issue, however. If you've ever changed a belt on this Stillen system, you know that there is very tight space between the fan housing and the tensioner. If that fan housing moves anywhere towards the engine as a result of the thicker radiator, you wont' be able to get at that tensioner anymore.
So is this a problem or not?

...Kinda off topic, but just curious:
Why do you hate the Eibach springs?

Eibachs always end up sagging. And, they are too low.. the car scrapes on every thing. And there is a point where the car is so low that geometry gets screwed up. These springs are past that point. They are for posing only. Soonest I can get rid of them the better.

Does anyone know if Stillen will be making a Twin Rotor SC for the G37?

Curious..

Here's the auto version if needed. Might be logical to stick with the external cooler? >

Thanks - I like this idea. Or, I might do the job myself, since I've been wanting to get in there and replace all the hoses to the intercooler with braided lines anyway. As long as the front cap is off, why not keep going and just do it all. I also like that monster sized oil cooler that is in the article... although it would get in the way of the transmission oil cooler. Maybe it's time to open the blocked off vent on the right side and put it in there.
I've not had good luck with supercharged cars here in Texas... this one keeps it's cool but it of course still slower in the heat of summer. Now that it's cooling down it's getting faster every week again. I'd like to get all the cooling totally re-done, and then go back to the dyno and see what can be done.

Anybody in Central Texas, BTW, want an ARK exhaust? It's too loud for my neighborhood... I'd like to move to something more reasonable.

I don't have an answer, but I'd find it hard to believe. What Stillen must have paid for the emissions work on this kit probably just about killed their margins. And if a twin-rotor SC is any bigger, it just isn't going to fit under this hood.
But the first questions is if Vortech makes a street-series SC like that... Stillen certainly can't go that far on their own.

I doubt it, Since GTM ones caused issue with the VVEL. At least that what I got from Sam's post, IT was casuing timing issues

2010 G37X Coupe 7AT

Hey guys this is a great thread, I was just curious about the Stillen Sc. I already have the stillen exhaust and gen 3 intakes. I was hoping to upgrade in the future possibly next fall to the Stillen SC kit, Oil cooler, and trans cooler. Besides those parts is there anything you guys would recommend for an automatic transmission AWD coupe? And has anyone with automatic transmission had any problems as far as power wise with the trans?

First, it's critical that those three things go together - if you don't already have the coolers. Even without the SC the G runs too hot - which if you've hit a racetrack you've found out the hard way. Don't put on the SC without the coolers.
I have a RWD sedan... and the Stillen SC makes *so* much power that my biggest problem is traction. The stock tire width will never handle it. You may want to get that upgrade over with before the SC.
You can see why the GT-R has to have AWD, and you can see the results from the acceleration tests. The 2014 will do 0-60 in 2.8 seconds. Phenomenal... yet the power is only slightly above what you will get from your Stillen SC kit. The important factor there is traction.
The auto trans is not an issue. 48k on my 7-speed with no issues.

Ok thanks for the info, I will definitely get both coolers prior to the SC. What would you recommend as far as the coolers go for my G37 currently. Traction wise I have upgraded to a set of Volk Racing TE37SL 18X9.5 wheels and will be placing a set of coilovers on and both F/R sways.

I'd suggest sticking with Stillen for the coolers... for a very good reason. There will also be a water-to-air cooler located off the front of the radiator... and it has to clear the oil cooler on the left side and the tranny cooler on the lower right side, as well as the factory power steering cooler (which is there, and despite it you can easily boil the power steering fluid on a track day) and the dual air filter elements. It's busy. All these coolers and lines get complicated... but sourced all from the same place they will all fit and not interfere with each other.
If you are plumbing in coolers, you might want to think about getting some temp gauges on them at the same time, if you're into the gauges thing. I didn't, but I do have to wonder what my temps are and would like to know.
Look at this pic from my profile on this site to see what all these coolers look like.

My car is an X also with Stillen SC and Stillen coolers. I love the SC it gives me the power to pass others when needed. I haven't noticed anything as far as transmission issues go. I have about 10K on the SC now.

One thing you should know is that since ours is AWD you won't be making the kind of numbers that the RWD does, loss of power from trying to spin all 4 vs spinning 2. There's a good chance the Stillen canned tune won't be right for you and will need adjustment. It took me 5 MONTHS to get my tune right. I still need to get my final dyno done. Before you start you might want to dyno your car stock this way when your done you'll know what your gain in hp is. ANMVQ says he made 412WHP with a custom tune.

If you buy the warranty for the SC you CAN'T get a custom tune that will void your warranty. That's why it took me 5 months to get my tune right. I had to keep going back to the dealer and they would have Stillen send them a different tune and I would try it. I think I went through 6 tunes before Stillen paid for a dyno tune which took 8 hours. The dyno shop would send the data to Stillen then get a new tune back then run the dyno then send the info back to Stillen. This cycle as I said took all day but now I don't have any issues with the tune and I have my warranty from Stillen. If you work with Stillen don't give them an attitude and have boat loads of patience Stillen will come through for you at least that's my experience. If you can afford to get this I highly recommend it...I don't know how to spin my tires as it just goes when I stomp on it. Hope my experience helps...

Nokaoi, that was a very informative post. As I'm sure you've noticed, these forums are filled with posts saying that the Stillen canned tune is terrible. But your post is the first time that I've seen someone work through the issues and arrive at a workable solution, all while maintaining the Stillen warranty. Thanks for sharing.

I agree, I did the same thing for the same reason. I was worried that there would be issues with fittment if I mixed manufacturers.
