What's GTM got up their sleeve?

That's what happens when you are the big man on campus Ron!

Thanks!

Yes, a TT 370Z can easily be driven daily. It drives just like a normal Z, only with a lot more power the more you press the go pedal.

Super. Thanks for the helpful posts folks.

I wanted to join in and commend GTM for their contributions to the Z34 platform. Coming from a long DSM background (no laughing), I'm personally very excited about this latest kit.

This kit sounds like it is a better match for the stock VQ37 for a daily driver on stock internals than any other kit out there. The size of the turbos, intercoolers and piping size will lend itself to faster spooling. At the same time, these turbos should also be capable of easily keeping up with the demands of 1.85 (half of 3.7) liters at the lower boost levels that are supported by the stock internals and high compression. As Big T pointed out, the 20G is actually large enough to flow enough air to supply over 20 psi to a 2 liter at 7K on the old 4G63. The V37Q, as Mike pointed out is a very different animal. In theory, a 16G is sufficient to meet the CFM demands of each cylinder bank at lower psi levels, such as 8.5 psi. I'm very curious to see how the pairing works in application.

For those concerned about the intercoolers ability to cool the intake charge, there are two things to consider. First, the air is not being super-compressed at the levels of boost we are talking about. Second, air-to-air intercoolers work off of temperature differential. As ambient air (outside the intercooler) passes through the fins of an intercooler and carry away the heat, that air is heated. The ability to carry away heat is diminished fairly significantly after about 1.75" (if I remember from either Bell or Coleman's writings). Air that passes through (inside) the rear of thick intercoolers does not experience nearly as large of a cooling effect. That said, GTM managed to stick a 2.5" intercooler between the crash bar and the radiator in their supercharger kit.

I also like the idea of keeping the crash bar on the front. In the event of a low speed impact, there would be no damage to the intercoolers; and the front tow hook will remain accessible should you ever need to use it.

On top of all that, making this kit more affordable is a significant plus.

How much cost would this save on a TT kit (ball park)

Here are some pictures of the kit that we are installing on an Infiniti IPL here at the shop. For more up to date pictures and updates, like us on Facebook as we are posting lots of various project updates almost daily.

Dear GTM,
Please design/figure some way to eliminate the need to drill and tap the engine block for the exhaust manifold. I mean you guys are able to come up with a twin supercharger setup!!!!! If you can figure a way around the drilling/tapping I will order this kit as soon as its available (please everyone save the future post about this not being a big deal, to me it is).

P.S. also those blacked out intercoolers gave me a chubby!

Mike@GTM

Actually, that is something that is already in the works. We would like you to know, however, that there is a really big difference between designing/making a new mold for casting and designing/making billet brackets. While billet brackets have a high per unit cost, the upfront capital investment in molds for casting is astronomical in comparison.

That said, here at GTM we are always looking for ways to improve our products and services in all aspects as well as respond to our customers' needs/desires. One example of that is our new 3.5" downpipes we are developing that have the ability to install high flow cats on our turbo kits as some people really want a more environmentally friendly option to make big power. Some people have wanted the factory crash bar to remain with our kits and that is why our latest design incorporates it as you can see below:

^Mike, that looks great, have the crash bar is one of the biggest reason i went with the SC, only if this TT kit was available earlier, i really like the way it's built

The piping is way shorter and more direct. Looking good. So are those Twin oil coolers I see?

One is a oil cooler the other is tranny cooler.

There's a lot of question going threw my head. But Ill hold out. But what numbers are expected? None of those added 100 octane numbers either. lol

This kit would be right up my alley for the track. Fast spooling turbo with just the right amount of power.

I am interested in those intercoolers. I lost my crash bar with the Greddy unit and those look like they fit the bill and will give me back my crash bar...........

Looks like you need a first Z to wear this kit ... hint ... hint ...
