Will the 16g option with internal waste gates cause boost creep issues with a free flowing exhaust as seen with the stage 1 Garrett kit?

Ok so tell us the difference between this kit and your stage 1 and stage 2 kit? I wish I would have known or heard about this before buying your stage 2 kit only a month ago since I wouldnt have to drill and tap a bunch of things.... Are the turbo's like the garretts oil and water cooled or just oil cooled??

We’ve been talking about this development for a while in this thread: GTM Performance Engineering: GTM TD05 16G Test Results 91 Octane 7AT

While we acknowledge the need to have a kit that is geared for a price conscious consumer, it is certainly not our intent to skimp on quality. As such, the MHI kit is a high quality system that uses components that are proven and reliable while being less expensive to manufacture. For example, the Mitsubishi turbos have been used in OEM applications for a long time with a great track record for success. In addition, Mitsubishi turbos are generally water cooled and engine oil lubricated. That said, there are forced induction solutions for this platform that use the oil cooled versions of the Mitsubishi turbos. Since we recognize the importance of keeping the CHRA cool, we use the water cooled version in our MHI kit.

One other major difference between this new kit and our current Garrett based kit is the philosophy driving the design. Our original premise for our Garrett twin turbo kit was big power and scalability. This new kit is designed with the premise of being less invasive to the car while keeping as much OEM equipment intact and undisturbed as possible with more than enough power for the stock engine. This kit isn’t setup for a Stage 6 1300hp setup the way our Garrett based kit is. We’re really going for solid, stock block numbers with unbeatable response with good power potential as well. The optional 20g turbos for example are capable of 880hp which is more than enough for the vast majority of people looking to do forced induction. The 16g setup is capable of making enough power to max out the stock block with excellent boost response and drivability. After all, there is no reason to have a laggy turbo setup on the stock engine when a smaller, more responsive setup is more than capable of delivering more power than the stock engine can take reliably.

This philosophy can be seen in our intercooler design and intercooler piping. To leverage economy of scale, our MHI kit uses a pair of intercoolers instead of the big single intercooler used in our Garrett based kit. Together these intercoolers are rated for 900hp while our big single on our Garrett kit is rated for 1000hp.

Keep in mind, that our Garrett based kit is without a doubt an outstanding system with top notch hardware that is tough for our competitors to beat. It still outspools the competition while delivering great horsepower and torque. In addition, our Garrett kit still has fantastic value, just at a higher price point than our MHI kit

Hmmm Everyone likes cheaper.

Wish I would have know they were coming out with a twin sc kit before I bought my sc kit a few months prior also!

Sweet baby jesus its a great time to be in the turbo market eh?

blackonorange

5700 for the tuner kit

tower74

WHAT??? That's STS prices!! Except with knowledge.

blackonorange

I paid 5g for the STS kit shipped all the way to Canada . So STS is still cheaper but this is twice the kit

tower74

That was my point. They had stated it doesn't matter what size of turbo you want. It all costs the same price. So again this is cheaper than STS.

Sorry for the dumb question, but is this kit the same as the one in this link?
