Red_Z

Is it possible to post link to the installation manual? Since I am in CA and nothing is legal, I want to see am I able to install/remove the kit by myself, in my garage.

I'm also interested in having installation details if this is possible.
I would like to get an installation quote with my local shop.

future370zzz

+1 on this.

My poor poor poor bank account.. They will never be "full" as long as GTM is in business.

Good numbers with an affordable price, i am sure we will see a lot of TT Zs in the future

Z370Z011

Haha right!... I wonder how much the monthly payments come up to if you give 50% down?

elperuano

Great kit! That price will be the selling point

rAiN

are the clutch upgrade necessary for this kit? I will only be driving around the town with some spirit driving session.
so if i get the numbers right, 6k for the kit + 1k for the tuning + 1-2k for installation?

elperuano

I think the tune is 5-600... The rest is a good estimate. U can keep stock clutch but it will wear out real quick or might not be able to hold all the power n slip.

Never heard of financing a Turbo/ Sc kit. (I understand people just use a credit card) Does the government know your doing this??

Everybody is gonna be FI now, so many G's/Z's are gonna be turbo'd/SC that people are gonna think Nissan brought back the 300Zx!!

Yes, there is a difference in spool between the three turbo options. With bigger turbos, you make more power at the expense of responsiveness.

This kit was designed from the outset to be very appropriate for the stock engine. Our Turn-Key kits are supplied specifically for installation on a stock engine.

One thing I'd like to mention is that you really want to keep the engine stock since it is the most reliable setup you can get. Purchasing a turbo kit that is designed to run on the stock engine is really the best forced induction decision you can make. 500whp is no joke on these cars and the fact that the stock engine can sustain that level of power for a very long time (60k+) is what is this kit is all about.

In regards to what boost the Turn-Key map is setup for, you need to remember that this is a Blow Through MAF setup. That basically means that it has more to do with mass airflow than boost pressure. Even then, the limiting factor is the factory return-less fuel system. That said, you don't really need to upgrade to a return fuel system until you are making more power than the stock engine can handle in the first place. So, basically, what I'm saying is that our Turn-Key kit with our tune can take you to the limit of what the engine can handle reliably and a little further. So far, that translates to roughly 11 - 12psi of boost.

We are still working out the details for the group buy and will be posting that along with more information on the financing options.

I'm actually still working on the installation manual between answering e-mails, pm's and forum posts. It should be all wrapped up before the kit starts shipping though.

We think that the price is really only part of what will help this kit sell. It's more about the performance/$ that really drives home the value of this kit. It performs extremely well compared to other options and costs substantially less as well. That, is value.

It should take roughly 25 hours for a competent technician to install this kit. Based on your local labor rate, that should give you a good idea of how much it is going to cost you to get it installed if you decide against tackling the install yourself.

The need for a clutch upgrade really depends on the health of your stock clutch. If it's hammered pretty hard, it won't last long and you should budget for an upgrade. Otherwise, if you have relatively low mileage on it, it shouldn't be an issue.

As for your numbers, I'm not following your math on that since we've given pretty good indicators on how much it should realistically run. $6k for the Tier 1 into pricing on the Turn-Key kit (no tuning required) + (25 hours * $/hour of shop labor rate) = installed cost.

As for the government, it's not an issue. I know it seems so good that it must be illegal, but there's nothing wrong with financing a turbo kit or sound system, house, car, or whatever else you care to finance. lol

Please post some pictures of the exhaust manifolds!. I think they are not shown on the posted pics at the beginning.

Also, do you have pics of the test car with an oil cooler installed? where can it be fitted?

Sam is their anyway to get this ASAP I'm ready to buy but need the kit ASAP.

SAM@GTM

We're trying to firm up the delivery date of the kit and we'll have that information posted as soon as possible. Keep in mind that we've been developing the parts for almost a year and have multiple components in the works already. Our objective with this kit is to have it ready and available on the shelf in large quantities.

For everyone else, we have a tremendous amount of PM's and e-mails and we're trying to answer them all as quick as possible.
