370z AT With Stillen S/C And The Upgrades
 

2010 Nissan 370z Sport/Auto Trans

Here we have a Z with some miles on her along with an 7AT, so I decided to go the Stillen route. Installation of the kit was done at Nissan Of Katy. Don the service tech did a fabulous job on the install. His work was very thorough, while he also made sure I too was aware of the step by step work being performed. I was very comfortable knowing the knowledge that stood between my car and the work being done on it. Once the install was complete, I took my Z to a local tuner here in Houston. Car ran decent but left a lot to desire, I wanted more of an OEM feel when driving normal. A few weeks later I took her up to Austin and had UpRev do a new tune. I found Mike and Omar to be very helpful with my needs and concerns. The car now runs great and shifts flawlessly all while putting down 426 WHP. Both Mike and Omar were highly impressed with the numbers produced by an automatic.

All in all I am very happy with my new Z! I say new because it feels like a completely new beast!

Nice set up and congrats!

Dash Command unit is badass

The dash is freaking awesome!

very nice car / project

i didnt see any transmission upgrades. hope it holds up.

Nice addition, glad to see another Houston area owner boosted!
If you have a dyno graph post it up and I will add you to the finished builds threads for boosted cars.

Looks GREAT SIR :tup::tup:

I've been beating on mine stock for over a year without any problems and 14 track days on it and counting.

How many miles does this Z have?

Nice build! How are the temps on the car?

That display in the cabin is sweet!

You upgraded the MAFs and went with 850cc injectors. Are you planning a lot more power in the future?

As of right now 78,400 miles! The car with the kit installed has enjoyed 2,000 of those miles.

Coolant Temps are right in line as a stock Z. Oil Temps are down from stock. I Don't drive her to crazy mostly Hwy, but have done some back to back pulls and even then Temps remain in check.

Believe it or not but the UpRev MAF's made a difference with the way my car behaved. Had them installed on the original tune and she ran and idle just fine. Had to come back for a re-tune due to time and was told to go back to the stock MAF's as they were over kill. I was like cool put a little money back into my pockets. Don removed them the night before the re-tune going back to the stock MAF's. After the re-tune the car did not idle so well and would stall after high revs and even times if I stopped fast. Also had a flat spot in the RPM range that was noticeable. At this point I went back to my UpRev MAF's and took her up to Austin for a fresh UpRev Tune. She now runs great and no codes! My guess is the location of the MAF's are probably not the best spot as there is some turbulence going on inside of that Y pipe!

Thanks! The display was the easiest install and yet it gets the most compliments! :rofl2:

That's good to know. I just upgraded to 3" intake tubes because my MAFs are maxed. Hoping that will buy me enough head room to prevent having to go to upgraded MAFs.

Awesome build bud:tup:

So nissan dealership did the install not Jtran? Wasn't that a lot more?

Yes, install done at Nissan. I shopped around and price was in line.

Here are two videos showing what was most important to me, the transmission. I was not worried about how the car would handle the new extra power, but how it would react and deliver on it. Unlike the manual guys, us auto guys pretty much need two tunes. One for the Engine Management and one for the Transmission. I feel like UpRev gave me both, remember I was seeking as close to OEM feel as possible. Video two was a WOT from 60 MPH to 100 MPH in normal drive mode. You can clearly hear the transmission doing it's JOB. Don't mind me fussing towards the end of the video as you can still hear the tranny doing it's job while closing the throttle to 120 MPH plus!

Nice build. What size is the frozen boost intercooler. Other guys had to cut a portion of the bumper support and it looks like you didn't. It fits in nicely.

You're probably aware of this but I wouldn't mash the gas on gears 5 thru 7 too much.

They turned it over, look where the tow hook is.

On the 5th-7th gear thing, I hit 5th twice every lap on Sebring at WOT and while it shifts slower I haven't broke it yet.

The FrozenBoost Intercooler is the larger one used in this application. Like JWillis72 said just flipped the bumper support, the only mod was to trim out the bumper. This Intercooler is a must have for this Kit. It really helps things from getting heat soak so quick!

As for mashing the gas "BOOST" in gears 5Th thru 7Th is part of the reason I went with this Kit. The TQ is nothing like the Turbo Z's and our Tranny's for the most part should hold just fine with a proper "TUNE" as the Factory Specs are around 290TQ. My Z put down 426WHP & 328TQ. I have done pulls to 150MPH plus and she feels firm and steady as the Tranny pops into the next gear, almost feeling like a true manual with a conventional clutch.

:tiphat: you guys definitely pushing the 7at hard.

Hey Jwillis,

I'm still trying to gauge 5th. What mph are you on 5th?

Trim out the bumper? Please explain in some detail what you mean.

Thanks

Cool! I didn't say we can't boost in those gears just that they get weaker as you go up. Don't know what speed it takes to wind out 7th gear in full boost but your tranny would be the least of your worries at that speed. haha

I'm just paranoid with the 7AT so I got the tune, valvebody upgrade and trans oil temp monitor. By the time i wind out 4th I'm already going too fast for comfort.

The factory torque specs are at the flywheel I believe, so your wheel torque could be 15% to 20% more at the flywheel. Don't quote me.

I want to say the shift to 5th is around 130 mph, I've never gotten to 6th at WOT. What kind of temps do you see in the 7AT on the street vs track?

No bumper trim
 

I appears that is can be installed behind factory bumper without doing any cut outs to the bumper. I like this look better, going to try to get mine to fit.

I bet that's the 2" thick one instead of the 3 1/2".

it is this one, 3.5" thick.
Air to Water Heat Exchanger

instead of modifying the crash bar, I am going to add a aluminum angle support to each side and bolt it to the bottom of the crash bar

Wow I wouldn't have thought it would fit. Does that car have oil and 7AT coolers behind it?

there is a oil cooler behind it. not sure about the a/t

http://www.the370z.com/forced-induct...z-swiss-4.html

I don't believe his car is a 7AT so he had more room. The OP car has a 7AT cooler behind his that's taking up space.

ok, gotcha!

The difference is my intercooler is mounted with the mount tabs towards the back of the bumper support brace. swiss370Z mounted his to the front of the bumper support pushing it a little closer to the radiator. Like JWillis72 mentioned my coolers are behind there so we went this route for the added space and flow.

Do you track this car?

No track for me, but will be changing out the radiator soon to help deal with this TX heat just around the corner. I really like what you have done to keep your temps down. :tiphat:

Did you have your tuner adjust the fan speed controls?
This is a big help in Texas, allows them to kick on at a lower temp, nice for traffic.

If you do that and don't track it the heat shouldn't be a problem. My car is probably not running warm enough to be a DD. My oil isn't going past 145 on the street in 70-80 degree weather.

That's a great idea, mine goes to 100% much lower and that helped. We also bumped the idle up on mine at hotter temps so it pushed the coolant a little more and it seemed to help.
