Hey guys,

i might be scoring dads unused Supercharger for the Z...

just wondered what mods i need to run 5-6psi boost on stock engine with a intercooler.

i aint to sure what the stock injectors/fuel pump can handle/ what the ecu can do as in being tuned...

;) thanks

Mr Gazza, As part of the HKS kit, both the fuel pump and injectors are upgraded, as there isn't much additional headroom in them. You'll also need something to control the fuel/timing as the stock computer won't handle the changes well.

vq35 vipec's plug ins are in development , v88 wire in would work right now although you would be the test guinea pig to calibrate the drive by wire (or ditch it) . stock ecu remains to talk to the bcm to control all non engine car functions .

be wary of the supercharged stock internal vq , they make a bucketload of low down torque even at small boost and are prone to hurting rods . even a basic rebuild with some forged stuff might be a good idea if for longevity if nothing else.

will be an awesome engine though , so responsive .

Hey guys,

yeah i wont be aiming for high hp, just enuff to piss on 6-7litres common-dores.

I've raced this dude in a yellow VZ 6litre HSV 307kw with a bucket load of mods, i had him by a few feet both on the lights and rolling pulls!

:) think i'd be happy with 5psi

i been reading stuff like this... which makes me think you can just bolt it on pretty much?

Yeah i'll call C-red n that see what they can do / reccomend.

Still open to ideas ect.

Manufacturer: Stillen

Manufacturer's Web Site: Here

Type of Supercharger: Twin-screw

Additional Modifications Required: New hood that will clear the supercharger. These are offered by Stillen as well as other companies.

Price:

Stage 1 - $3,795.00

Stage 2 - $5,239.00

Stage 3 (Pulley Only) - $89.00

Stage 4 - $849.00.

Approximate Installation Time: 10-12 hours.

Future Plans: Stillen is reportedly developing a larger blower. They are being tight-lipped about it, but I was told it will work with the same hoods that work for stages 1-4 and most of the Stage 4 components. I would say it will have to be an M90. It will probably also have a larger intercooler. All of this will bump up the power quite a bit. The new upgrades are expected to be completed by the end of 2006.

There are 4 stages:

http://www.stillen.com/superchargers..._Guide_USA.pdf

Stage 1: This stage features the base supercharger with 6psi of boost. It includes everything needed for installation.

Stage 2:This stage features the base with 6psi, and it adds an intercooler as well as a heat exchanger with a coolant pump (with its own coolant) placed underneath the superchargerand.

Stage 3: This stage replaces the base pulley with a small pulley that increases boost to 7psi.

Stage 4: This stage features a new fuel pump, a larger 7th fuel injector, smaller pulley and remapped FMU (Fuel Management Unit) which increases boost to 8.5psi.

Mr Gazza, I personally wouldn't rely on what Stillen post on the internet, go talk to one of the tuning shops that have supercharged a Zed (C-red or Xspeed) and they'll have alot more useful info of what is required. I agree with Autoworx that the VQ35 isn't a strong internal engine, unlike the VQ30, so don't chsae too much power.

Cheers

With the HKS S/C on my V35 it was good enough for 312rwhp on only 6psi boost.

Internals were fine for street use.

Same power and less weight than a HSV you do the math :-)

S/C less likely to harm rods than a turbo setup

:D Thanks all so far for your input, more is still welcome!!

Hey Chris, so u have you Supercharged yours / or someones 350z?

I just really want to know if all the stock stuff will be okay 'ecu/fuel pump/injectors' and can the stock ecu be tuned? i cant seem to find anything.

But i am calling C-red tommorw, i had to get valentine stuff today so had no time!!

And guys as i have stated a few times, i dont want 1000000 RWHP or my rods ect getting thrown through and out the side of block LOL !!

Its pretty quick as it is and most things cant beat me.

I just want it for a bit more power / BOV and yeah cause i can :)

i was going to go the same way, to supercharge the v35 but got quote 14k (including labour cost etc) and this was through with vortech. one of the members JaiK before had one for sale and it seemed mint so i wanted to do what he did. he managed 360hp and 1/4 was under 13s. he did his at c.red.

but in the end...i spent the money buying another car :(

i'd rather turbos bro coz they force induct and hold boost on, but lots more work involved aswell as cash aswell... s/charger is bolt easy induction mod really... takes few % of power you gain coz the pulleys n that!

still deciding and getting ideas myself

    • Yes that’s what im trying to decide. Should I do stock gtt box or enclosed or open pod. 
    • Also, I note OP is in Melbourne, which begs the question... are you aware of how illegal your car will be with a turbo, and intercooler and any sort of filter change? I don't know how you can get past the "2 intake mods" "rule" that seems to exist in Vic. Fully engineered might or might not get you there.
    • If you have a turbo... then the ducting holes I used to feed the pod are not available because your intercooler likely uses them. If you have an intercooler, your IAT's are going to be goverened by how good your intercooler setup is. I'm yet to really see anyone check IAT with a snorkel/boxed pod/proper CAI versus and unshielded pod. It would be interesting! But I suspect that the differences would not be so noticeable as if you were N/A as the intercooler is where the air is being cooled.. and out in front where the FMIC would be is a pretty good spot for it.. When I was turbo I pushed the stock GTT box as far as I could and made some pretty good power out of it, and noticed on the street I never made the same power/boost. Then I did a before and after run with a pod filter versus the box and picked up about 9PSI from the same boost duty cycle and about 50KW instantly. I never ran the stock box again, and recently removed it for my N/A setup. The box is restrictive to a degree - Even with the V8 setup I noticed I picked up power by removing the box completely, so punching holes from the bottom of it to get air from the passenger guard *helps* but the most effective one in my case was simply having the ducts, a pod, and no box around it. In my experience, *more* air was better than cold air. The air (with ducts) will be cooled off as you start moving, and especially if you start moving fast (a race track). It actually moves around quite a bit as you can see.  
    • Well you could certainly buy or build an enclosure for a pod in that corner of the bay. It is absolutely vital that there is a nice big opening to let cold air in to it from the front or underside, otherwise it will just pull air in around the edges from the bay, and if that air is hot, you gain nothing from enclosing the pod. There is lots of good evidence around (including on here, see posts by @Kinkstaah for example) showing that pods pulling hot air from the bay is only a problem when you're static or slow in traffic, and that as soon as you get the car up and moving the air being grabbed by the pod cools down. Although that will obviously vary from car to car, whether there is a flow of cold air to the pod or if it all has to come through the radiator area, etc etc. Obviously, the whole exercise requires as much thought as anything else does. Doing the lazy thing will often end up being the dumb thing. The stock GTT airbox has a cold air snorkel to feed it from over the radiator. Shows that Nissan were thinking. The GT airbox is upside down compared to the turbo one, yeah? Inlet at the bottom, AFM/exit on the lid? That might make it harder to route the turbo inlet pipe using the GT airbox than a turbo one. That would probably be the main reason I'd consider not using it, not that it is too small and restrictive. I'm looking at a photo of one now and the inlet opening seems nice and large. Also seems to have the same type of snorkel that the turbo one has. Maybe all that's required is to make a less restrictive snorkel/cold air inlet, perhaps by punching down through the guard like I did.
