Question: Are those exhaust manifolds welded or cast?

Answer: The exhaust manifolds are investment cast stainless steel.

Question: What turbo's are those?

Answer: The turbo's are Garrett GTX2860RS, also available Xonarotor 49.48 (HTZ-2868 Billet Wheel) and Xonarotor 78.64 (HTZ-3579 Billet Wheel).

Question: What type of exhaust housing is that on those turbo's and why not the "traditional" T-3 style?

Answer: These exhaust housings are Tial. All flanges are gone and everything is a v-band connection. These housings are designed for max efficiency through the entire RPM curve and reduce the overall amount of space being taken up. This gave us more clearance in all directions in the design process. It allowed us to design the exhaust manifolds without having to "drill and tap" the passenger aluminum head of the engine in order to make the exhaust manifold fit the car! In addition, we will not offer an internal wastegate option and this housing eliminates having to weld internal wastegate flapper doors shut of external wastegate applications. On the driver side the compact nature of this housing allows us to retain the "stock" steering knuckle.

Question: What are those exhaust elbows bolted to the turbo's.

Answer: The exhaust elbow bolted to the turbo's start at 3 inches with a smooth taper down to 2 1/2" and end in the stock location of the starting point of the catalytic converters. Yes, this means you can run any existing cat or test pipe in stock location. In production these elbows will be cast.

Question: How will you recirculate the wastegate back in to the exhaust system?

Answer: We will recirculate the wastegate directly into the exhaust elbow coming off of the turbo's. This will eliminate the "plumbing fitment nightmare".

Question: Will this kit fit both the 6MT and 7AT (Transmissions)?

Answer: Yes, it will be designed for both.

Question: Will this kit fit the RHD (right hand drive) model?

Answer: I am not certain but I would venture to say no it will not fit. Until I have a RHD car in our shop to do a test fit I will not know. Anyone who wants to send one our way, just shoot me an email.

Question: What will you use for tuning?

Answer: UpRev or EcuTek

Question: Why are the BOV's (Blow Off Valves) welded in the innercooler?

Answer: In order to (properly) relieve pressure off of the system the BOV's should be post innercooler. In this case they are. You should put them as close to the throttle bodies as possible, however we did not want to put them too close to the MAF's. To close to the MAF's will can create turbulence in the intake tubes. This will cause the MAF's to work improperly. Now in our case we chose to weld them directly to the top of the innercooler for aesthetics, ease of installation and symmetry.

Question: What size is the innercooler tubing and why is it that size?

Answer: The innercooler tubing is 2.50" all the way though with the exception of directly out of the turbo's. The silicone transition out of them goes from 2.0" to 2.5" virtually immediately. After doing extensive research we are confident that this specific car does not need anything larger. The G37 lacks low end torque and we want the turbo's to spool as fast as possible. We are however prepared to test 2.75" if need be. As for 3" as the intake tubes, yes aesthetically they look aggressive but from a performance standpoint we feel that intake tubes that large will create turbo lag.

Question: Is the innercooler made up of one or two cores?

Answer: The innercooler is one core. It is however completely sealed directly in the middle. Each side is fully independent to the other. We have a left to right passage and with one core you are able to achieve more cooling rows. This will allow for better cooling and in the end a more efficient innercooler.

Question: Are we able to keep our crash bar with this innercooler?

Answer: Unfortunately no you cannot keep your (stock) crash bar. To do so would cause us to use a much smaller innercooler core. In addition the power steering cooler would have to be virtually up against the radiator and the innercooler as well. This would cut off a lot of air flow to your radiator and guaranteed to make your car run hotter. The coolant and oil temps are already hot. We did not want to add to the issue! *NOTE: We may develop and offer an aftermarket crash bar before the kit is in full production.*

Question: Why did you choose to put the air filters in their current location?

Answer: As you can see from the filter to the turbo inlet the bend is extremely minimal. The straighter shot, the faster the turbo's will spool. In addition this is a good location to keep the air filters from potentially hydro locking. For those of you who like to take your car underwater!

Question: Will the innercooler tubes always be welded together in multiple pieces like in these pictures?

Answer: Once in production, all but 1 maybe 2 out of the 8 innercooler tubes will be in one piece. There should only be 1-2 welds in all of the tubing.

Question: Will the wastegates recirculate back in to the exhaust?

Answer: Yes, pre stock catalytic converter location. For testing purposes at the dyno we will dump them into the atmosphere. We will most likely need to change wastegate spring pressure on the dyno and for ease of access having the recirculation tubes off and out of the way will speed things up.
