I am going to be installing this kit soon so I tried to mock everything up on the workbench. This brought up some questions. Looking over everything, I might also be missing some hoses and an idler. I am trying to bounce between the Stillen instructions and the Topgunz conversion instructions and I found that there are a couple holes in both.

1. I bought the SpecialtyZ 3bar MAP sensor which does not fit the OEM MAP sensor port on the Stillen manifold. I am guessing that I am simply going to bolt on the OEM MAP sensor to the manifold and not connect it. The 3bar sensor is going to be zip tied to something, the OEM MAP sensor electrical connector is going to be plugged into the 3bar sensor, and a new hole is going to be drilled and tapped for the the 3bar sense line. Is that correct?

2. In the Stillen instructions, the port on the manifold between the TB's is supposed to be connected to the purge valve. However, my manifold was delivered without the purge valve connection and the hole is simply plugged with a set screw. What am I supposed to do with the purge valve if the purge valve port is plugged?

3. My kit did not come with any hoses that are called out in the Stillen instructions. The only "hose" I received in my kit was 5' of tubing to connect to the bypass valve and also short stainless steel braided line that is plugged on one end. I have no idea where the braided line goes since I can't find it anywhere in the instructions. I also did not receive any of the 3/8's or 5/8's hoses or plastic tees that is called out in the Stillen instructions for the vacuum lines. I am not sure if this was an accidental omission from the kit or if they are not needed for the A2A conversion. I think they were accidentally left out since I seems like I still need to install the breather lines and add a breather filter onto the 5/8's tee. Is that correct? If so, does anyone know where I can find/buy the 5/8", 90deg hoses?

4. I marked up the vacuum diagram from the Stillen instructions. I just wanted to verify that my "corrections" are correct.

5. My blower bracket does not have a 7 rib idler that is shown in the Stillen instructions. My kit came with a small idler pulley but it does not fit in the bolt hole where the 7 rib idler is supposed to be. Is there supposed to be a 7 rib idler in the kit that was left out? And what I am supposed to do with the smaller pulley?
https://i.imgur.com/Jxteqe3.jpg
I can answer #5. Look at the 4th picture down on the first post of this thread, that will show you where the small idler (which is a tensioner) pulley goes. You are missing the 7 rib pulley.

TopgunZ 03-11-2019 12:49 PM
Your steel braided line is for the supercharger drain, which you will place on the supercharger where the drain plug is currently at.

There is not a pulley missing as you re-use a pulley that you take off of the car when doing the install. This is called out in the instructions.

You do not need any other hoses as those are only for CARB and there is nowhere to route these. That is why there is 2 breather filters sent with the kit. One for each side of the valve covers.

The purge valve needs to go to the manifold. You can either T into one of the 2 on the back or get a barb like in the picture. Let me know if you want me to send you one if you need it.

fork 03-13-2019 01:11 PM
Thanks for the replies. That cleared up alot.

One more question about valve cover connections: The breather filters go on both PCV valves. What do I do with the connections for the valve cover air inlets (the connections with the 5/8" vacuum hose shown on the Stillen vacuum diagram)?

For the 1050 injectors, I guess there is no easy way to pull the wires from the stock injector plugs so that I can just plug them into the Injector Dynamics clip. I have to use the splice kit?

Also should the metal spacer ring on the 1050 injectors be left on our taken off?

Install them exactly as is, don’t remove anything. You’ll want to crimp the new terminals. There is a video on YouTube that shows you how, it’s very simple.

Edit: Ended up cutting all of the rubber off of the front of the filter to get the bracket to fit flush. There was only about a 1/16 inch gap between the timing cover and the bracket bolt hole near the center of the car when we removed the rubber and dropped the SC assembly in for a test fit. The bracket pulled in against the timing cover when the bolts were tightened. Currently trying to get the Y-pipe to align with the throttle bodies which is also giving us fitment issues. Any tips on getting that aligned would also be helpful.

TopgunZ 03-25-2019 07:12 AM
That is the first time I heard that someone couldnt get the bracket on. It is a tight fit but nobody has needed to cut away at anything. Can you PM me your name. I do not have you on my spreadsheet.

To get the Y pipe aligned, a good trick is to soak the pipes and couplers with windex. That way they spin easily and will slip into place when they need to. Dont worry about using a bunch as guys will inject that stuff directly into their engine if they run out of Meth/water.

Tell us what you're getting and how much it is. I did most of my shopping on black Friday, but have links to all the places I got stuff from and what I paid.

$5650 if $100 cheaper than what I paid for my kit and that WAS a black Friday deal. You should get it! :)

I’ll need to get injectors and research the fuel system I need. That’s confusing me the most. I’m going to have Seb tune it since he did my current tune. I’m not looking to go balls out in power since I have the 7AT. Just want a reliable driver that I can track once in a while.

Senna-F1 03-25-2019 05:04 PM
Topgunz can get you injector and PnP adapters.

Charles at CJM is the best to talk to. He can list everything you need. You're probably looking at the S1.E Fuel System. Pump. Pump Wiring Kit. I think you can get away without the pump hat, not sure. I went a little overboard on my setup so can't just tell you what I got.

If you're gonna track, you'll need an oil cooler. I just went with the Z1 oil pan spacer for now.

fork 03-25-2019 08:54 PM
Well I got everything in and the car runs so that's good news. I took it around the block and made it back to my garage which is also good.

Something I noticed when I brought it back in was that the supercharger was ticking. I didn't notice anything vibrating off anything metallic and I also checked the supercharger oil level.

Make another video twisting the SC side belt.

At idle the SC will rattle. It is simply the backlash in the drive gears as the engine is constantly changing RPM during idle (it is not an electric motor, it changes RPM as each cylinder fires). Once the SC has a load on it it will be quiet.

Sorry to go alittle off topic but does anybody have any pump gas 1/4 miles times with this kit?

I haven't seen any, but a 1/4 time from any Z with similar HP would be the same. 500 HP = 500 HP, regardless of how, or even where in the rev range, it's made. The tires couldn't care less where or how the power is made.

Some people around here will tell you a positive displacement supercharger like the one from RJM will be faster, even if the HP is the same because it has better low-end torque. Complete nonsense. Any 500 HP car has MORE than enough power to break traction from a dig. The key is modulating the power and having more of it down low, in 1st gear, just makes that task more difficult! Once you get to that 6000-7500 RPM range, where all of the racing is done, it's all the same. 500 = 500.

Dahawkster 04-04-2019 03:26 AM
Does anybody have any 1/4 times non pump gas then? I only see one guy from Guam running 12.7s. I would be pretty bummed to spend $7-$8k to supercharge my Z and be stuck doing high 12s only. If i seen people cracking low and mid 11s I would of bought this along time ago. I've been waiting for people to post there time slips with this kit but I haven't really found any yet..

I dont think you understood my answer, but I hope you find what you're looking for. Be sure to post some links if you find it. :driving:

Senna-F1 04-04-2019 05:19 PM
Is this the guy you are talking about? He’s *not* running this kit, and his car is not tuned. A stillen 370z with their tune sometimes makes no more than a full bolt-on 370z.

https://youtu.be/tsK4pRrGIhY

Fast Intentions went 12.4 then 11.4 with the same car. Like I said it’s all in the launch and controlling the power. They did this on only 8 lbs of boost on their turbo kit.

Here's Evan's running an 11.6. If I'm not mistaken, that was on 12 psi.

Maybe but not always. At one point mine was pretty quiet at idle besides the whine. Then I had to mess with stuff from emissions, adjusted the built and yea now it chatters at idle. I was thinking it was from the tune having added cats and the blowoff silencer but maybe not
PS you still got that belt? I gotta paypal you my bad my ADD is real

Your belt could be too tight. Back it off some.

Dahawkster 04-06-2019 12:19 AM
So I have just a couple more questions please. I am really thinking about picking this up but I am just very unfamiliar with superchargers sorry.

What PSI pulley does this kit come with? I am assuming 10 but not sure and will anybody be able to tell me whats the highest amount of boost you've ran on pump gas safely?

If you where running say a 14psi pulley are you able to hook up an electric boost controller to run less boost if you wanted to for daily driving?

What would be the smallest/high boost pulley this kit would be able to run efficiently?

Reasons I ask these questions is because I would like to run lower boost on 91 octane but be able to up the boost from in the car and run as much as I can with
water/methanol injection and tuning of course safely...

Senna-F1 04-06-2019 12:57 AM
I’ll just mention this since it may not be apparent. Boost with a centrifugal supercharger, like the one in this kit, is directly related to RPMs. Boost rises in a linear fashion as revs increase. With a “15 psi pulley” you will only hit maximum boost at redline, typically 7500 RPM. So you may for example only be at 12 PSI at 6500 RPM. So you can control boost by controlling RPM and shifting early.

It sounds like you would have 2 maps. One with meth injection and one without. You could just get a high boost pulley and then have your non meth tune with a redline of say 6500, which would keep your boost below max. Your meth tune would rev to 7500 and give you full boost. No other form of boost control needed.

These number are theoretical examples, not actual real world numbers.

The kit comes with the 9lb pulley on the serpentine side which should give you around 10 psi.
I was able to run close to 13 psi on 91 octane before I started getting knock.
I controlled boost using a 38mm wastegate and ebc. I was running e85 and 91 octane. I set the boost controller to open the wastegate at 12 psi when on my 91 tune snd stay closed on e85 tune. Or, if I turned the boost controller off, the wategate would open at spring pressure of 10 psi for daily driving on either 91 or e85.

thank you redondoaveb for the reply I really appreciate your help....So you actually installed a wastegate on the charge pipes :confused: or are you just referring to the Tial QRJ that comes in the kit?

I didn't expect the torque to to drop so drastically in the upper RPMs. I would be really stoked with something like that green dyno run with pump gas and meth. Will this kit simply be able to achieve those boost numbers by just changing a pulley and belt?

If you changed the sc pulley to a 2.85 it would get you close to 13 psi. Pump gas and meth might get you there. Prior to adding the wastegate, that set up got me 586whp on e85. It made 491whp on 91.

Changing pulley and belt will definitely help you increase boost but the problem is your tuner has to pull a bunch of timing back to avoid knock if your using 91. The only advantage of using aggressive setup is that you can have your torque come sooner (better low-to-middle end). In addition, the torque depends on the supporting mods. You can also gain torque/boost by simply putting a restrictive exhaust system. However, it will not only increase the back pressure as well as exhaust gas temperature but also loose top-end power.

It’s not back pressure or a restrictive exhaust that adds power. It’s all about exhaust gas scavenging. I don’t know of any serious builds that are running a stock exhaust. My Motordyne equal length long tube headers and exhaust are only going to add power, and not because they are more restrictive.

Motordyne LTB is actually not restrictive at all. It's straight-through design with pipe diameters (1-5/8″ primaries stepped to 1.75″ to the 2.5″ merge collector) larger than the OEM one and can definitely benefit power, while at the same time decreasing EGT. A true "long-tube" header featuring equal "gas flow" length helps the car separate exhaust gas pulses well, thereby making power and better preserving torque. However there will be a whole different circumstances if you put stock catalytic converter back. You will see better boost but loose power and increase exhaust pressure as well as EGT. Moreover, the cat isn't going to last long.

Yes, that’s my point and why I purchased both. It was your statement about putting a restrictive exhaust on to gain power that I don’t agree with. You now seem to be saying the opposite so I’m not sure what you really meant to say.

I didn't say it will add power. You completely misunderstand it but that's OK. I just said it will add "boost" but loose the top-end power. :)
