I thought about that , But I'm sure there's a way for them to see the flashes on the ECU, IE how many times or something, or everyone would do that. Maybe their flash is locked and can only be loaded once or some other BS the dealer flashed it into my car when they were done. Its just an a risk I did want to try. I don't think it would have made a difference either way with mine. They would have found out some how that it wasn't their tune.

They do lock their flash and they will not let you see it or use it as a starting point for a custom tune.

I understand that but you still have the file whether its locked or not. If you have it custom tuned that is a completely separate map file. Reflash it back to stock and then reupload the Stillen tune. Number of times its been flashed shouldn't matter because you could have had it tuned NA before the SC. The only hiccup I could see would be if the flash has a time stamp (i.e. after motor let go).

Not like it really matters as it appears no one purchases the warranty anyway. It's probably voided if you do the install yourself too.

Hey Mikey

With the high temps in summer up in QLD you might want to consider a larger heat exchanger. Considerable improvement on the stillen one.

Air to Water Heat Exchanger

ENJOY

fantastic, thanks everyone very much for the info so far along with recommendations to improve the kit right out of the box.

has anyone installed the kit with the 9lb pulley and used stillen's tune to start the car to check for leaks and also drive to a shop to get the tune done? They have advised to obviously not drive the car on the tune they provide with the 9lb pulley and say it has to be tuned straight away.

I would only be driving very calm/not high revs for 50km (31-32 miles) to the shop that is going to do the tune on my car, should it be okay to drive or should I only start it, check for leaks and get a tow?

It will be drivable with the 8 lb pulley just might be rich.

If your going to run the 9lb pulley you will need a shorter belt as the tensioner is at the end of it reach with the standard kit supplied belt. You will want a 7PK2635 belt. I discovered this yesterday.

Even when ordering with the 9lb pulley to start with? I haven't seen this mentioned before but will keep this in mind and check the belt when installing, did you start with the 8lb and get the 9lb supplied afterwards?

Bought the kit with 8lb pulley and before even starting the car I took the 8lb off and put the 8lb on. Stillen said I would need a new belt but we think the old on was allowing belt slip. New shorter belt on and the tension feels better. Still need to data log it to see if it was previously slipping and loosing boost.

okay fair enough, I've ordered with the 9lb, so hopefully receive the correct belt lol

thanks for heads up though, I'll be checking everything :)

While I'm getting everything organised guys, is there any specialist tools I'll need to do the install? basically anything to make the job a lot easier/faster, don't mind spending some $ on tools. I've got all the basic socket sets/jacks/jack stands/torque wrenches etc.

Any clip tools to remove the fuel pump?
just a generic spark plug removal tool or is there a specific tool for the Z?

what's a good A/F ratio gauge, anything to make use of the main screen to display this?

As far as tools maybe some ac disconnects if you have to pop any of those lines, after that it is all pretty basic, maybe a dremel or body saw for widening the hole in the core support for the intake tube. dremel makes a nice diamond wheel that makes plastic it's bitch, its for ceramics. the only other thing i can think of is a compressor and air tools to make everything faster.

sweet, cheers man! I've got a dremel, don't have ac disconnects, will wait and see if we have to take this off before buying the stuff for it.

you are going to need a thin walled deep 14mm spark plug socket if the install involves spark plug swap.

I run the innovate afr gauge and like it

Make sure you get the intake pipes lined up properly behind your front bumper. This caused huge issues with my tuning for a few months due to it not being lined up properly. If you have questions PM me =)

P.s.
Enjoy ;-D (also running the 9lb pulley)

Congrats! You're going to love it.

my blue point and craftsman 14mm deep 12 point 3/8 sockets both work fine for plugs. he said he has standard socket sets so i assume he has one with a 14mm deep socket.

I'm not a fan of using 12-pt sockets on spark plugs

Good to know.

This is a MUST either way, Theirs being bolted the radiator make NO sense:ugh2:

Who sells the impeller and what's it called? I been interested in going this route.

Where do I get this impeller?

The Vortech SI impeller upgrade requires you to send the blower unit in and they replace it for you and check for any issues. Check out the Vortech site for complete details. Its about $350 plus shipping. http://www.vortechsuperchargers.com/page.php?id=13896

There is also the 928 motorsports impeller upgrade but I heard mix responses because some say it doesn't quite fit and others have made it work. I just went with OEM and called it a day.

i beieve the 928 impellar requires you to also instal the si impellar cover, the sci cover it the wrong trim

you guys get it good, to upgrade here in aussie is over au$1000 plus shipping

Okay so I've also ordered the frozenboost heat exchanger + motul mocool :D

good move

Ok thanks! I'm guessing I'm gonna need a retune too right?

^Yes, with changes to boost level, definitely.

yea you'll see at least 2 more PSI up top but mid range will be more like 4-6 PSI, you will build boost sooner in the RPM band. Retune for sure

Shipping is estimated to arrive Friday 27th according to tracking! (please please no delays!) so will get started on Friday as soon as it arrives.

I've got my tune booked/penciled in for the Monday morning 30th!

I've been told I don't need to drop my oil/coolant to do install. As my car is due for a service, I will be doing this on Monday, but I've also been told I'll need to add some oil/coolant once the kit is installed. Does anyone know how much roughly? as I'll get some extra while at the dealer.

So far with the tune, couple things I'm going to get checked/done;
1. Have the fans come on a bit earlier temp wise.
2. Get them to do some hot starts and make sure I don't have a hot start issue.
3. Some vvel tuning if they are comfortable.
Anything else I should definitely be getting done that's kind of not a normal thing?

I lurk here quite a bit and thought I'd offer this 0.02 cents. The V-7 YSi has the same bolt pattern and pushes nearly 40% more cfm.

edit: typo with the v-7. Thanks 1slow370

V7

If you plan to run test pipes, have them disable the map sensor trigger under DTC controls. My car throws a CEL every once in a while when I mash on it. It's not suppose to see boost so it throws a CEL p0106 code.

Been running Berk HFC's for about 2.5 years and never had a CEL, still get this disabled? as I'm guessing the HFC's will burn out eventually anyway?

A word of caution ...

Upgrading the Vortech Impeller Upgrade to SI trim and then combining it with the Stillen 9 lb pulley can give you too much boost for a stock 11:1 motor.

Thats what I did ... it produced 11.9 lbs of boost @ 6900 RPM ... 483 whp : 378 tq.

The motor didn't hold together very long ... blew on the first 1/4 mile pass.

Am now in the process of having the long block built ... an expen$$ive le$$on

not upgrading the impeller, it's too expensive here in Aus for the gains. Maybe down the track when I change to E85, might be an option to do at the same time.

Thanks for the heads up though, appreciate it.

btw Z&I, when the motor is built, are you going to take it even further with the kit or just run it as you had it when your motor died?

What about nitrous? Anybody run nitrous with this kit yet? How does it perform with it?

Hey man just so you know I did the Stillen SC kit with my friend in his driveway and the only thing that we did wrong was we didn't realize that the supercharger came filled with oil and the manual only had one little line saying how it came filled. So we put the bottle of oil that came with the kit into the supercharger because the dip stick read empty but it wasn't and it caused over fill spray onto the strut brace and on the bottom of the hood. Also I got the 9lb pulley and it actually got me up to 10 lbs of boost
