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

Paul

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

    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
