Very nice! Are going to TX2K13 this year?

I'm not sure yet but a large group of our Houston Z's group is going. Facebook Houston Z Cars

Damn Dansracing, that is a very nice, clean look. Overall the entire car looks awesome.:driving:

I agree!!

It looks great! :tup::tup::tup::tup:

:confused:

Thanks everyone, I like it too! Really like how the Stillen SC is performing right now as well.

TX2K is one of the biggest car shows in America where a lot of the big horsepower cars meet. It last for about 3-4 days and has a series of events.

The TX2K event started as a small grass roots Supra only event in 2000 and since that time has grown into a national car event that attracts hundreds of cars and thousands of people from across the United States. At the 2010 event, we had 26 of the states represented including visitors from other countries. In addition to a strong continued commitment from the Supra community, this event draws a large number of other car enthusiasts including Porsche’s, Viper’s, Lambo’s, Vette’s, etc… The event schedule follows the same basic format each year.

It would be nice to see some high horsepower Forced Induced VQ's make it to the event.

I watched the install and tune, Ron & Johnny are a great team. Car is sick bro, hope to see you at the shop some day. My car has been sleeping there for some time, bought to go under the knife.

Just an update. My 2013 Stillen SC 370Z has settled down beautifully. For the last year the car has run flawlessly reliably. !2000 miles. It just runs, every day, like it was factory built with the SC.
I am very pleased.

It just fixed itself?

Great to hear, mine is almost 5,000 and running perfect.

Hello Guys

My 370Z has been running for 3 years and 18,600 miles with no problems
(OK! A ball bearing was replaced under warranty of my Tuner!)

Now the project of new intercooler is coming.....:excited:

Stay tuned

Ivo

Wow 3 years 18.6k miles. Must be a weekend toy!

It is only driven in nice weather ...
but then, on the swiss mountains :tup:

Would appreciate some advice on the following, please:

Planning to get the Stillen SC kit in a few months but already purchased BERK HFCs and Stillen cermaic coated Headers very recently, and now don't know whether to install them or shipping them back to Z1.

I've been getting confusing advice as to whether the Header and HFCs will be good or bad for the SC kit. :confused:
Have heard Stillen strongly recommending against the headers (loss of psi and lean A/F), as well as, headers working well with the kit. And HFCs not being able to take the extra heat.
I am seeing some member here running header+HFC with the SC kit.

Any advice?

My advice is keep stock headers and cats. I had HFC's and one cat blew after a few hundred miles. When I went back to stock cats per Stillen, I made more power also. A few other's I know personally also lost power when going from stock cats to ART pipes and went back again to stock cats to get the numbers back.

Check this out!

Who has a Stillen G37 Supercharger? Numbers, pics, vids! - Page 26 - MyG37

Thanks diego@vossen. Very enlightening and helpful indeed.
It just puzzles me why in the name on science would a better flowing/more efficient header/cat make the SC lose power.

Either way, I'll try to return/resell my brand new Headers and Berk HFCs.
:tiphat:

Don't quote me but I read that it's has to do with the forced induction causing blow by in engine from the lack of backpressure (free flow from test pipes/hfc).

I probably have it half correct. haha

Eventually your stocks cats will burn up and need to be replaced though.

Anyone have idle that fluctuate at times ?

I've also noticed loss of coolant and I have to top off the radiator a few times

My idle fluctuates when I accelerate and then start slowing down. During idle it's pretty consistent.

Mine is erratic and im waiting for a response from Stillen as to when i can bring it in so they can check it
Just seems that after they take the money customer service goes out the window

Agree with Diego send them back to Z1 and use the extra funds torwards the SC kit. An Stillen will tell you themselves also to not use HFC's or headers with their SC.

I have Motordyne art pipes but stock headers. I'm running 415/310 on 93 and around another 20whp with 100LL. However I had 2 invida test pipes break and 2 cbe tanabe break at the welds. Also make sure you get a strong fuel hose that attaches to your fuel pump. I had to get a new engine because mine was severed I ran lean. Make sure you get an air/fuel gauge to monitor.

No crap really!!! Same thing happened to mine, Fuel feed line was junk motor went BOOM:wtf2:

Have you switched to coolant yet? I know you said you were running water and water wetter and that might be causing the issue. Coolant raises the boiling point of water and if the pure water (and water wetter) is boiling you would be getting air bubbles in the system. This could affect the idle as the ISC is affected by coolant temps (air bubbles going through the ISC can cause erratic idle).

home-made boost gauge
 

On my search for a low yet accurate boost gauge suited to the Stillen SC kit, which didn't get far, I got the idea of actually making one instead.
Most Gauge go at least to 25 or 30 psi. What we want is no more than 10 psi. And the accuracies of mechanical and electronic gauge are beyond scrutiny. We can but hope that 8psi doesn't actually mean 7 or 9psi.

So I was thinking of getting a suitable BOSCH MAP sensor, they are highly accurate (OEM parts) and very fast response time and have a very linear output across their range. All we gotta do is display that output as eg. LED bar or digits. It just needs a little voltage conversion to express that output voltage in numbers representing psi. Electronics wise this is very simple. The display possibilities would be endless too.
Saw this inspiration for a BMW:
http://cdn3.volusion.com/54u7z.db265...5i-Gauge-2.jpg
The challenge is finding a cost effective BOSCH sensor with calibration curve available. I looked at this cheap fella #0 261 230 191 (used in supercharged Mercedes and others) with a pressure range of 0.15-2.6 bar (up to 23psi boost) but no datasheet.
Whereas the #0 281 002 119 (up to 22psi) has a datasheet saying response time is smaller that 10ms and accuracy is ±1.5 kPa, that is ±0.2psi guaranteed accuracy! But this particular part is pricey.
I keep searching, maybe I get lucky :stirthepot:

The Stillen SC kit seems like an addition I'd love to install on my Z. For those of you that have this Stillen SC kit, what would you advise I'd do to my "stock" engine along with this upgrade.

Thanks!

The Stillen SC kit is specifically designed to bolt onto a stock 370Z/G37.
But recommended add-ons are a 2.5" catback and an external engine oil cooler.
A boost gauge and A/F wideband gauge are optional additions, too.
You don't need to make any other preparations.
Stillen advises against headers or downpipe/cat upgrades.
I am gonna get my SC kit early next year, that's the plan anyway :excited:

A larger heat exchanger is always helpful. I'd put an upgraded radiator on any boosted Z. And you really need a custom tune. The canned one leaves a lot to be desired.

I'm about 3hrs from Z1 MotorSports & was planning to have them do the install & tune. I have the F.I. TDX Catback Exhaust. Thanks for ALL the input!

I thought I was the only one! Wow! I almost had it happen twice. The second time I noticed when I went to dyno my car. It has a steel braided line that is super strong now.

Switch to coolant days back and its gotten worse
I drove to the track and before I left pit lane the car thru a service engine light
I put on a scanner and it said lean bank 1and 2
We cleared the code and I tried going for session 2 and 2 laps in the light came on again and car started to backfire and no power
We cleared the code again and I just drove it home
Cars idle is erratic still and while driving now sometimes surges ,what sucks is i told you guys about it and I feel like I wasted time and money today for nothing
I'm seriously thinking of putting the car back to stock
You guys kept all my old stuff injectors, pump ,etc.. So it shouldn't be a problem

Like Chuck said the larger heat exchanger( Frozen Boost ) is a must IMO, and DO NOT to mod the kit for more power, and the "new" one is replaced the crappy stock fuel line with a breaded metal one.
If you mod it to make more power( You should make 410-415WHP) then be prepared to buy a motor, Seems like any of us that chase more power with this kit fail. I chase 500whp got 457 and BOOM but with the info on the feed line from Chris I think??? I know why mine popped, and might be why the others have went to , Guys are popping CYL2 or 3( I did 3)

zmanelite, you should not be driving the car!
let it get looked at by an experienced tuner, looks like there is something wrong with either your map or fuel supply.
If it is throwing lean codes, it is definitely way to lean for forced induction

as for the P0106 MAP range problem, tell your tuner to disable the DTC in your map file (this is normal, the MAP sensor is not supposed to see positive pressure, as it is an N/A vehicle after all)

I would definitely recommend adding an AFR gauge, for any kind of aftermarket boost it is essential to always know AFRs are good, especially if you floor it

As for downpipe/cat upgrades, i read a lot about that and most people will tell you that downpipes/cats or TPs will decrease boost on the stock pulleys/impellers.
I have just installed this kit, i am running stock headers, berk HFCs, Motordyne XYZ Pipe and Tanabe Exhaust, so pretty much everything except for headers.
I am seeing 8psi on the dyno and 9psi on the road, so i consider this to be a myth.

Check the fuel line that attaches to the fuel pump. Also because the fuel pump is bigger than the stock fuel pump the filter on the end of it was not staying on. This made the fuel pump float in the fuel pump assembly. With this happening my car would always have fuel starvation issues on turns. I've tracked my car 3 times. So what we did is tie strap the fuel pump to the fuel pump assembly. Now I have no fuel starvation issues. I also have the heat exchanger that comes with the kit and it works fine. I'm sure if I upgraded to a bigger one it would be better but my car is running perfect now. Trust me I know your frustration. I had so much trouble with thus kit but finally for about a year now it's been running good. I got it installed in 2012.

My car was customed tuned and it's running 415/310 on 93 and another 20-30 whp on 100LL. All my trouble was from the fuel line. The tune had nothing to do with any problem. But since I had so many problems I'm not going to put a smaller pulley. I want to but I think more power now is not a good idea. Since is running good now I'm going to leave it alone.

can you elaborate on this?

I had this ONCE:
P0106: Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem
I reset the code and had my tuner tune the range of the MAP sensor to a higher threshold. At least what he told me ,I never can back on again. I would look at that for an option. That also may tie to your lean code NO?

Agree, Mine was close to that before I started pushing for 500 WHP, made 412WHP and 300 WTRQ.
