Im so ready for this to be released its driving me crazy (girlfriend to). What worries me is its going to be awhile. AWHILE, before it is. I won't be ready to install till after ZDayz but after that I hope something gives. I support GTM all the way I just hate being in the dark. Which I completely understand why shops do this. I would to.

I just have so many things that's has to be done when this goes down. Plus on top of my other plans. I'm going to have my TT kit powder coated the same as my wheels. But have the intercoolers thermal coated. About to order more gauges but I really need to order all this things threw GTM. Just hard to hold out. Lol. I've already ordered TT shirts. So it's definitely happening.

congrats on your soon to be boost, this kit is a great choice

SPOHN 04-25-2013 01:08 PM

I think I'm going to fly out there for a night to see the shop. It would be a fun one nighter.

blackonorange 04-25-2013 01:27 PM

I know what you mean, idk what to do do i start ripping my car apart or what?

Dzel 04-25-2013 04:47 PM

I'm just waiting on the installation manual to make a decision on what I'm going to do.

Same here. I've got a daily driver so if it takes two weeks for me to install in my free time then I'm fine with it.

370zrider 04-25-2013 05:29 PM

What would be your exhaust setup recommendation if I want to keep the Stillen exhaust?

I saw that Cosmogirl had issues trying to set the Stillen exhaust with gtm's 3' test pipes.

Footloose301 04-25-2013 05:31 PM

Test pipes are the way to go. No cats. They will burn up from the extra heat.

SPOHN 04-25-2013 06:01 PM

Open dump is the way to go.

Nice talking to you today Sam.

:iagree:

I bought my cbe for street use but at the track is gonna be as open as Kim Kardashian. :roflpuke2:

Footloose301 04-25-2013 07:44 PM

Lol not sure if i want that kind of attention


Edit: then again I've never even been pulled over in the Z. No cats, and fully tinted windshield too lol.

Too bad there isn't a turn-key kit with external waste gates.

tower74 04-25-2013 08:26 PM

What size are the injectors that being sent with turn-key set? Will 600cc work? Or are they to small? I'm really not liking the internal and no external option

For the injectors? I have 6 600cc injectors collecting dust...:tup:

Dzel 04-25-2013 08:37 PM

No the waste gate issue

The fuel injectors are going to be 725cc. This size is an all purpose solution to the amount of power/ size of turbo you choose. Especially a 20G turbo. This way the the duty cycle of the injectors is kept lower along with the pulse of the injectors has a lot of tunablility.

I'm sure GTM will give you an option for EW on the TK kit if you want but it will cost.

It shouldn't be to much more. The only difference between the turn-key and tuner. It is only the basic fuel system and the UpRev tune that make them different.

Footloose301 04-25-2013 08:46 PM

What kind of adjustability will we have on the turn key kit with internal wastegates? I'm new to this and learning as I go. I am thinking 10-11psi for track use and 8-9 daily..... Just turning the nut on the wastegates rod?

The fact there is no option for external waste gates on the turn-key kit. Not much difference between the turn key and tuner.

If you look at both tuner kits with the IW and EW it's $400 difference. But Sam might have a different reason for that.

I know but why can't we have the same option on the turn-key. That's what I would like to know. I mean hell the kit is the same.

You will not want to make adjustments to the wastegates. These is where a boost controller is needed. Also help with boost creep and spike. But that usually has to do with types of setups and exhaust types. But this kit was made around these two ideas so this will most likely not happen. But why not have another fail safe along with the ability to adjust boost. I'll run lower boost on street/ track then high boost when someone needs to be taught a lesson.

As I said in my first post I'm sure GTM will.

I am on the list and out of curiosity what additional items are needed. I have a 6mt

blackonorange 04-25-2013 10:54 PM

Clutch, upgraded Csc and oil cooler. Bam your done

Spark plugs, oil cooler, if you are not getting the turn key, then a basic fuel system upgrade---fuel pump upgrade plus injectors, maybe a clutch and exhaust.

The last two are if you want to try to get the most from these kits without doing an engine build...

SPOHN 04-25-2013 11:15 PM

Some supporting mods can be a must and some can be held out on but be ready.

Spark Plugs: It was said it can run on stock plugs. But one step colder is your best bet. Helps reduce temps which aids with pre detonation. $160-$180.

Clutch: The kit can push some good number and pending that along with how many miles are on the car now and you have treated so far. The stock can handle a good bit. In due time the day will come. So with a clutch and HD CSC about $1200-$2000.

Oil Cooler: Should already have one if not get it. 34R $700

Others can be radiator, shroud, fans, boost controller, and A/F gauge. Just depends on how serious, how much, and how hard you going to drive. And if you don't already have a good exhaust.

Thanks...looks like I am in decent shape. Subconsciously I've been choosing what seems to be the items needed for boost..;).

Greddy ti
z1 34 row cooler
Oil temp gauge
Oil pressure gauge
BOOST gauge....;)

I would add a wideband O2 in there somewhere.

What the heck are these spark plugs that cost up to $180??

HKS one step colder and NGK plugs that are also one step colder. HKS has the advantage. They help reduce temps which helps with pre detonation. Also has something to do with timing.

MX52Z 04-26-2013 12:47 AM

Thank you. I've been using colder plugs over the years for other FI applications but those have usually been $1-$2 a piece. Just blown away at the price of Z plugs and just wondering if it's necessary to change since they're already in the colder 8 range for a stock (non FI) motor to begin with.

Yea I'm not sure what are plugs are. But the stock plugs still can be ran with this kit. I believe the HKS plugs are GTR plugs also.

Dzel 04-26-2013 01:02 AM

Yup you can run the stock gtr plus

Gotcha. Yeah this is why many prefer external waste gates I suppose.

Is there any reason the HKS electronic boost controller like the evc 6 will NOT work with this internal wastegates?

I want to be able to adjust between 8-11psi.

Sam / Mike will work something out with the external wastegate kit - that's what I pre-ordered. I ordered it in the turn-key setup...along with a few extra special goodies. :happydance::driving::icon17:

Just waiting on final price and ship date!
