Hello Wayne!

The kit requres no modification at the original engine. The installation
should be made by a meccanic. The price of the whole kit is 3600.- US$. The
maximum speed will be approx. 250 km/h. We accept VISA and deliver the whole

best wishes

That is a good deal.   If I hadn't already bought one relatively
cheap I'd get it.  ;) 

In case anyone here hasn't heard, Garrett was finally officially
contracted by Z-engineering to do all their chips.   This is good
news as the one thing that is really lacking with the Z-eng
kit is a decent chip.   It runs way too rich in the meat of the power
and about the time the tires start smoking, you bang into the
rev limiter which was set artificially low.   Plus the stock speed
limiter was still there, so one hits 130mph while still accelerating
hard.   With the upcoming chip it'll rock on.    Two people with
DSR 256 cams and a Z-eng with GIAC chip are both putting down
almost exactly 240hp to the ground.. (275 conservative at the crank)

That's not bad for a blower that peaks at only 7psi or so. 

The kit has not been without its teething problems, like any relatively
new S/C application.   The first gen kits had the ceramic bearings and a 
few of them self destructed.  The second gen kits had oiled bearings with 
a small resevoir.  The third gen kits (which is what tom has) have oiled 
bearings with a larger resvoir.  They had a problem with the anodizing 
wearing off the drive pulley which caused the oft mentioned belt slippage. 
 That's been fixed.   With the upcoming chip update (unfortunately not 
free because of what Garrett is charging Z-eng) it should be pretty much 
fully sorted.   Even now it still keeps me ahead of the chipped
1.8Ts at a mile above sea level (where turbos have a big advantage)
and I think I can take the WRX fairly easily as long as it's not
from a standing start.

The Z-kit is awfully nice....... 8-) In all serious though I think the Z-kit
is the lowest output but best sorted kit available. We get A LOT of requests
to do software for folks with AMS/Eurotech set ups.... The Z-kit uses GIAC
software and is very well supported by Z themselves as well as the dealer
network, of which we're the NW dealer.

You have the AMS and Eurotech kits to pick from if you want a Vortech
Supercharger based system, these are basically the same kit.  The other
system is the Z-Engineering Supercharger system which is easier to install
but makes less power.
Do not bother with getting a Eurotech system.  They have and are giving
anyone wanting one WAY too many problems that I won't get into on here.  AMS
(kit I have) is basically the same as the Eurotech kit and was the original
manufacturer of a Vortech based kit but their software is a bit dated and
could be improved on.  I have had no problems with their customer service
but have not had to deal with them much.  They do not seem to be interested
in updating the software or making any further upgrades to the kit.  They
almost seem to not even care about selling it.  As far as the Z-Engineering
charger goes you get a easy to install kit that has had 3 generations of
updates.  The updates are a good and bad thing.  They improved the kit but
were also done because of many problems that the kits were having.  They put
out less power but don't cost any less.

The rest is up to you to decide on how much power you will be happy with and
if it will keep you happy.  Don't get me wrong about the AMS kit.  There are
still things that you can do if you want even more power and the regular
software it comes with is ok.  I'm sure that the Z-kit will also be getting
power upgrades as well but I don't think that the charger they use will ever
be able to compare with the Vortech charger being used in the AMS and
Eurotech kits.

The Z-eng kits haven't been without their issues but overall I
think there are a lot more happy customers than unhappy ones.
Plus in an emergency the Z-kit can be removed quite easily.
I had a belt failure on a trip that turned out to be because
of a bent water pump pulley.  I removed the kit and returned
the car to stock in less than 2 hours beside the road.

>2.  Will I pass MA inspection with the z kit?

There's been a thread about this on the vortex and a couple people
have passed the emissions test with newest Z-kit and GIAC software.
If we're talking about a full on poke and prod in every crevice kind
of inspection, then the answer is probably no.  But then you can
take the kit off in about 1 hour, go get your inspection, come
home and reinstall in the next hour.

>3.  What else would I need or want to buy to compliment this kit?  Does it

The Mk3 kit isn't very complicated, so it's not hard to include
everything.  Make sure it's got the filter for the secondary air pump.

>What types of mods might I be interested in

>Which are the best for this setup? 
DSR 256 cams and 5bar fpr are the way to go.  Mostly because Garrett did
the software for it (no software support for the 248 FI cams for instance).  
A Z-eng with DSR cams seems to be good for about 250 whp.

>I also suppose that my new magnaflow
>2.25 cat back will not cut it anymore?

Probably not a problem to stick with what you've got.  I think a larger 
exhaust here would just make it feel more peaky with most of your gains at 
very high revs.   Turbos can benefit from enormous exhaust systems
because it makes for the highest pressure differential across
the turbine possible, which makes for faster spool up and more
flow at the top end.    A 2.5" exhaust wouldn't hurt, but I don't
think it's absolutely necessary to enjoy the Z-eng.

>4.  Will my stock tranny hold up to the added power that I would be
>putting to the wheels?
That depends on how you drive.  For a lot of people, the stock diff
fails under the stress of stock power.   Personally I think one 
of the best power mods is a TBD (Quaife or Peloquin), regardless of
whether you have FI or not.   I think it's really a necessity 
for FI though.

My Peloquin gets way more use on twisty roads and even around town
allowing for very quick exits from a parking lot into the
street or the occasional drag race around the outside of a double
left turn lane.  A TBD is not just for drag racing.

4 grand no.  3 maybe..    Depends on how many miles you've got on
it.  I've seen em as low as about $2500.

I need to qualify my own statement here.  You need to make sure to
let the car adapt to the stock chip before you take it in for
the inspection othewise it'll fail the emissions test.  Still
it should only cost you about 2 hours for removal and reinstall 
of the S/C even though it may be spread out over a couple days. 
If nothing else it'll give you a new appreciation for it when
you compare it to stock power levels.
