Your car is curently there getting the 16G TT kit?

I'm curious to see the graphs between the two since previously they released the graphs for the 16Gs and now the numbers listed are for the 18Gs

Nixlimited

Correct. I am curious too!

I was also hoping the turn key would have external waste gates as well but I'm about 90% positive I'm getting in on this group buy in about 2-3 weeks when I have my money.

SPOHN

I'm doing this for sure. But will have to wait till after track season. Might just go built motor then.

red6spd

That's what I'm saying!!! I'm getting $3,500 back. So hard to resist. Why did I have to teach my GF about turbos why??? I could have just hid it from her and told her I changed the exhaust or something. LOL.

The G37 you are referencing was tested on our old DynoJet. We have a Mustang dyno now that reads lower. That is why the current numbers are lower.

We charge 25 hours for installing our turbo kit. That should give you an idea on cost based on your local labor rates.

You are correct. Really, the financing company requires a MINIMUM of 25% down. Obviously, if there is a difference between the cost of the kit and the maximum amount they'll finance, you'll have to contribute the balance.

Yes, we provide detailed instructions with pictures. I write our manuals and since I'm not a tech by trade I don't take various steps for granted and really work to spell things out. At the same time, most people don't read walls of text, so I let some of the pictures do the describing for me as well as add diagrams as needed. Overall, I'm pretty picky when it comes to manual writing and really do my best to ensure that they are as complete and thorough as possible. In addition, our techs proof read the instruction manual with a virgin install to ensure that every aspect is covered and that the manual flows properly with what needs to be done in what order.

The G37 version will be available at the same time. We just posted the press release over on the G37 forum as well.

There is no welding required with any of our kits. We design our kits so they are effectively bolt on systems. Since this system is designed to be as unobtrusive as possible, the factory motor mounts are retained as well as the factory crash bar.

The recirc pipes for this kit are different from the Garrett kit due to various factors.

As for the boost curve difference, we will be able to show that on Nixlimited's car once it is completed since his car will have the 16g's. We will also be doing additional testing and verification with that system as well.

We charge 25 hours to install the kit in-house.

At a minimum, we recommend a transmission cooler whenever doing forced induction. Here is a link to an article I wrote on the subject of adding forced induction to automatic transmission cars: http://www.gtmotorsports.com/Technic...ansmission.pdf

Mike@GTM

Yes, of course.

Well, one of the advantages of our Garrett ball bearing kits is the fact that the ball bearing turbos will outspool the journal bearing turbos. There is no refuting that. That said, for the price, the MHI is a great way to go since you'll have money left over to put towards building up other aspects of the car (suspension, brakes, exhaust, gauges, etc). At the same time, if you are looking for ultimate performance with unbeatable spool, then our Garrett kit is the way to go.

Either way, both systems offer advantages and disadvantages. Really, the defining characteristic is going to be budget.

3" downpipes with external wastegates.

Thank you for your kind words.

We are putting together some install packages that we'll be adding to our website within the next day or two. Once I've got that in hand, I can send you a PM.

Mike!!!

Congratz on new official release!!

Mike@GTM

Thank you sir!

Yes, we will be selling the oil pan separately.

I'm not as knowledgeable on these things so forgive my questions if they are obvious. Is there a difference in spool time/latency on each of the turbos? 16g, 18g, and 20g? I would think there would be but don't really know.

For the turn-key setup, is it good to go and safe with a stock setup?

What boost is the turn-key mapped at?

For the financing option 2, when would the 25% down be required? How long from when you get the group buy list together are you collecting?

Thanks for your efforts in making what looks to be an amazing product. This has made me seriously reconsider my timing on upgrades.
