The only reason that the headers did not work on the stillen SC for the 350 was loosing 1 lb of boost because of the valve overlap in the vq 35. My 5 AT made 303 rwhp with headers. Does any body now what the valve over lap is in the 370?

I wouldn't be interested in the race kit unless I could run 93 on it. I'll run 100 at the track, but I would like to be able to drive my car every day without having to get race gas. I *think* they are calling it the race kit because it is not CARB legal and is probably "for off road use only". I dont know, but I doubt it will need to have the AC removed or any shenanigans like that. I would think that because they dont have to worry about emissions, etc. then the kit will make a bit more power than the CARB kit and will spool a little bit faster.

I am interested in the answer to this question too.

Umm, simple, kinda... you have to buy tuning software to reflash the car. The cheapest of which is still a few hundred dollars + tuning.

Unless a shop has a lot of experience with UpRev's reflashing software and with the VQ37, it will be somewhat risky. There's only three Uprev authorized shops in your country and I'm not sure which ones have experience with the VQ. Not sure Cobb's software is capable of handling aftermarket forced induction and there's only two authorized shops in Canada. Other than UpRev and Cobb (and Technosquare in So Cal), who has cracked the VQ37's ECU necessary to tune it in the first place?

Lol where are you getting your info man?

Tuning the VQ is like tuning most other NA cars...mostly anyone can buy the uprev stuff....FI tuning is not that complicated...VQ tuning is not complicated.... Mines also has an ECU upgrade...

Spend more time on the boards, less on the company site :)

What shop are you considering?
I have a few recommendations and suggestions.

Pm me for the info

PM Sent. Also to Buddy...we arent talking about a full tune from scratch. We are talking about slightly changing the AFR. Hell i know nothing about tuning anything and i was able to learn and adjust my 08 ZX6R with the power commander in a few hours.

With the turbo cars I had we could go and get a tune for $500 that matched the mods we had on our cars and it would be at about 95% perfect, we didnt really nede to get a custom tune that would cost more than a grand for that extra 5%. I never heard of anyone having any problems with the tunes. Can NA cars get the same type of tunes according to their mods? I would think most mods, ie CAIs, exhausts, etc for our car all fall in the same area as far performance, air flow gains, etc., so cant tuning companies just write tunes for just an exhaust, or an exhaust and CAI, etc?

Whenever you do a pre-packaged tuner whether it's for NA or FI cars you will get about 95% of your full potential. Depending on the type of the tuning device and the type of vehicle you're tuning you can safely estimate that the tuning device included in the kit is costing around $150-350.00. Obviously this depends on the type of vehicle (Nissan's are more exclusive and therefore more challenging than GM's and Ford's.) Also, if the company is supplying a stand alone ECU then the cost of that tuner could be estimated even higher and around the $1,000+ range.

The $150.00-300.00 is just for the tuning and the delivery method, handheld controller, computer program...whatever. Some tuner's are more expensive and can cost upwards of $600.00 or more but generally with those tuner's you get more than just a pre-set tune. That price range does not include any additional fuel pumps, injectors, wiring, fuel rails etc. for the FI guy's.

If you go into a tuner and say "here, tune my car." You can estimate that you're going to spend between $700.00 or more. Obviously this depends on the tuner's experience with your type of car, the tuning device they choose, and again it will depend on the vehicle being tuned. Some tuner's might take 10-12 hours to nail down the tune...some might take longer, some might be even less.

So basically, what you need to ask is yourself is: "Is the extra 5% of power and performance worth an additional $XXX.XX?" The tune that you will receive with your FI or NA tuner from the manufacturer will be safe, reliable, and give good power. But, it is correct that it will not be tailored to that specific vehicle being tuned so it will leave about 5% of the full potential on the table. It all comes down to how much it's worth to you and how much you're willing to spend.

This is the exact reason that we will be offering the tuner kit. This will be the perfect kit for people who want to do their own tuning and it will save them some money up front so they don't have to worry about spending it again later on.

We just received the prototype castings back from the foundry and they look AMAZING!!!! I can't wait to post pictures soon!!!

We have done all of the engineering of this kit in house and we have produced a couple of rapid prototype intake manifolds which are a plastic material that allow us to check for fitment and we can even send them out to test airflow and what not. The parts that we ran on the car a couple of months ago were actually plastic prototype pieces. This allowed us to watch all the belts and check alignment and confirm the engineering before going into the casting process.

We obviously don't have an aluminum foundry in the back of our shop so for some of our products we have to outsource to specialists. Then the parts come back to our shop for final machining and finishing before being assembled with the intercoolers and the rest of the kit.

The company who does all of our castings also manufactures parts for some of the largest manufacturers in the industry including:

TRD
Roush Racing
DART heads
Chrysler
Cosworth
Bombardier
Edelbrock
and many, many more.

We are also very proud to say that they are based in the U.S.A. This is very important to STILLEN. Too many companies these days outsource to other countries and we try our best to keep all of our manufacturing in-house or at least in the U.S.A.

I guess I'm mad cautious, bro, since our VQ has a more complex valvetrain and higher comp ratio than the older ones. I figure there's less margin for error with tuning it for forced induction and would only be comfortable with shops experienced with working with them.

Here are the pictures. Keep in mind these are prototype pieces. I did not spend any time in setting up the lights or the camera to make them look all pretty for advertising photography. I am terrible with setting that photography stuff up (lol) but I just wanted to show you pictures of the new intake manifold.

This intake manifold started life on the computer. Our engineers used their 3 dimensional CAD programs to develop the intake manifold then they printed out a 3 dimensional plastic model. This plastic model is known as a "rapid prototype" and basically allows us to check fitment and confirm that our engineering is accurate. Unfortunately I do not have a good quality picture to show of that rapid prototype piece right now. During its testing life the plastic prototype has been changed and modified so it does not look very presentable in its current state.

Here are some photos from the CAD development:

As you can see we have relocated the driver's side throttle body to be inline with the passenger side. This will allow us to have equal air pressure to each throttle body and a more consistent airflow. Also, by changing the intake manifold we can install our dual pass intercooler which will cool the air charge right before the air goes into the motor. Another added benefit is lengthening the intake runners which will also improve torque and accleration.

Here are some photos of the prototype castings. These are raw castings so they will still need to go through the machining process to have all of their mounting surfaces faced and drilled and tapped but these images will at least show you the progress that is being made.

Enjoy!

Thank you so much!

By the way, we should have more photos in the next week or two of the manifold on the car and running and what not...

Wow. Looks really nice. I am very excited to see this kit hit the market. Manifold would look sick if you guys machine the lines and the stillen part to make it jump more from the casting.
