Welcome! In for pics after your CBE install.

A GTM stage I SC or TT will take you to about 450 RWHP, FYI.

:iagree:

CBE as a first mod is always a good choice though, it gives the car some life.

:tup:

Unless you plan to force induce right away, because you won't need that intake anymore if you do.

no lame mods here .....the next one will be gtm stage 2 superchger and stillen long tube headers or gtm twin turbo i have a budget of 8k rigth now but i want best bang for buck and i am leaning hard on the stg 2 superchger

the guys at je imports work on stillen superchgers with there own custom tune

but i have heard bad things about stillen f.i including low hp numbers not sure why maybe its there tune that comes with the blower but vortech is a good blower thats what i am using on my mustang

but i like the over all stock look of the gtm kit

Either way, the CBE is a great starting point because you will be getting one anyway for N/A or F/I. Hell, I had my CBE before I had my NISMO, lol.

Right now, Stillen does not have LTH's, only Fast Intentions and PPE Engineering do, and the Stage 2 S/C the Fast Intentions (And probably PPE as well..) LTH's will not fit together.

I think the Stillen kit numbers are fine IF you do a custom tune after install. There seems to be a lot of good reviews on the GTM kit (stage I) but delivery seems to be the main problem...people seem to have to wait for months. At this time if you decide on stage II, you'd still be an early adopter...you may have to deal with some of the associated growing pains as kinks get ironed out.

The Vortech unit is nice, but the Stillen kit is a little too interesting for me. I would roll with one of the GTM F/I options because they already worked out the bugs for the most part. Otherwise I would go custom.......

I got my gtm stage 1 in a week. It was a long week tho. It took a lot longer to return the stillen kit

LOL.....3 related replies at once.

Awesome guys!

I had JE Import Performance weld in the bung for my PLX AFR sensor after another infamous tuner in the region quoted me north of 500 for doing one bung.

I finally saw a Stillen SC in real life. The install due to their intercooler/intake manifold looks nothing like stock where as the GTM SC looks like you just have a set of long tube intakes. Much cleaner in my opinion. I hope my GMT SC gives me none of the headaches his Stillen unit gave/giving him, so far so good...



You should head into the Mid-A section of the forum. we have a large and active group...

Guess we will all see how it goes soon enough.

:iagree:

We have weekly meets on Saturdays alternating between Columbia, MD and Fairfax, VA. You should meet up with us someday, I would love to hear that Ark exhaust in person. :D

Here's a link for more info on the meets:
http://www.the370z.com/mid-atlantic-...rday-10am.html

That is good info............maybe I can check you guys out when I come home on leave......

You live in/near the Mid-Atlantic area?

I am from Baltimore......stationed in Texas......deployed to hell (right now). I am in Baltimore at lease 2 times a year, unless deployed...

Awesome! Just post up a thread in the Mid-Atlantic section whenever you're there next and maybe we can have like a dinner meet or something. Or you can just come to our weekly Saturday meets too. :tup:

That's wassup! Sorry or getting off-topic guys.....

thxs for the info guys ...i dont see many 370z around here so to find a few guys to hang out with would be cool i will chk out the mid-a post....

i will be calling gtm on monday to get turn around time on there kit hell maybe they can talk me into getting the turbo kit i will cross ref. it with je imports they qoute me round 1000 bucks to install a superchger kit we will see

Sounds reasonable for the install (actually sounds pretty good price wise). I did my own install in about 30 hours.

I too want to hear that exhaust. I have a Nismo take off on the car right now and may be looking for something with a bit more growl...

there are alot of videos on the ARK CBE around the forum and on youtube if you need an example.

True, but it's still nothing like hearing it in person :tup:

:iagree:


It is very hard to tell how an exhaust really behaves unless you can get a ride in the car and really listen at the important RPM ranges and speeds.

Might sound good in a video but then have horrible drone kind of like Mustangs F.I. exhaust. We only went around the block and I KNEW that exhaust was not going on my car...

Gotta love Mustangs............

I love my F.I. TDX. Hopefully, I will be getting an upgraded one for my TT application. Still need to check with Tony.............

Dang, I wish my GTM supercharger coulda came in a week! Still waiting on mine.

Wasn't that bad when I sat in birdman's car. I guess everyone has a different tolerance level that they're willing to accept.

Mustang= m4a1mustang, and the FI on his z:tup:

Also different when you live with it day-to-day

Ok change of plans after talking to the guys over a je imports going with the stillen supercharger they even gave me a $500 buck discount so money talks lol....

From looking at the kit I can't tell the size of the pulley that comes with it. But I know vortech has a nice number of pulleys for the v-3 same as my v-2 on my mustang I am running a 2.87 on that......but I am also running a larger crank pulley on my mustang

I wonder if that pulley next to the supercharger pulley on the back of that bracket could be increased in size to turn the supercharger pulley a little faster just a thought

Ordering the stillen hfc also


Stillen supercharger + stillen hfc + ark cat-back exhaust will be tuned by the guys a je imports coming soon

The pulley that is normally swapped out on the Stillen kit is the one on the front side of the bracket that is run off of the main belt (via the crank pulley) although I am sure that you can swap any of the 3 pulleys (front side drive pulley, jackshaft pulley or supercharger drive pulley) to get what you are looking for.

The standard pulley that comes with the kit (approximately 8 PSI at sea level) is right at 3.125 inches (I have that one sitting here on my desk). The Stillen replacement pulley that provides around 9 psi of boost at sea level is right at 2.9 inches (that one is on my car now).

I am thinking of swapping it out for something around 2.5 inches as I am at 5400 feet ASL here in the Denver area and am only able to make 7.2 PSI out of the 9 PSI puley. As you stated, Vortech has a good selection of replacement pulleys and 928 Motorsports also makes a nice selection of replacement pulleys.

Good luck and I hope that you have the same good experience that I have had. The custom tune is definitely the way to go.

The Stillen kit uses a 7 rib pulley set up vortech only sells a 7 rib 3.12 pulley thats it. If you look on there site as well as 928 motorsports you will find 6,8,and 10th pulleys. I think you would be better off going with a cog pulley set up on the back ,or a larger crank pulley instead of smaller pulley than the Stillen one. If you go smaller than you are asking for belt slippage problems.

Welcome to the darkside, please pick up your flame suit at the door.

:tup:

Good one :icon18:

Cool...

Will be nice to see another SC Z in the area. Hopefully the Stillen will be trouble free.

K

I believe that it is actually a 6 "rib" pulley as there are 6 "ribs" (7 channels). The pictures of the 6 rib pulleys on the 928 sight have the same number of ribs as the pulley on my desk which is 6. I could be wrong but I always thought that ribs referred to the raised ribs on the pulley and not the number of ribs on the belt.

RCZ, I am surprised that he has not been torched yet LOL!
