The wastegate discharge pipes have a flex tube. This prevents differential expansion from the wastegate tubes from stressing things causing the piping in the system to crack.
One of the most important issues to consider with the R35 GT-R is heat control in the engine compartment. The R35 has aluminum shock towers and aluminum loses much of its strength past 350 degrees. Hot stuff like the manifold is right in the vicinity of those shock towers. Not only does the stainless material of the manifolds reduce heat in this area but the kit comes with these full coverage stainless heat shields to give the towers more thermal protection.
The ETS kit can come with large diameter charge pipes but we had them make pipe that could go to our Greddy OEM compatible charge pipes. The turbo inlet pipes are large in diameter due to the ported shroud compressor housing but will taper with a reducer tube to match our carbon big pipe inlets.
Sure, there are turbo systems that can make more power that radically relocates the turbos, but with these kits, you have to do things like forgo the air conditioning and re-engineer a lot of the stuff under the hood. However, we like the refined attributes of the GT-R and don’t want to decontent it. It’s not being built as a race car. The ETS kit can make upwards of 2000 hp depending on your turbo selection and 1100 whp with less lag than stock which is what we are shooting for.
Stay tuned we are waiting on parts so we can begin work on a fantastic 4.1-liter motor and our heavy-duty transmission from Shep Trans. Our plan is to build a very sophisticated motor and powertrain with excellent driveability and a wide powerband.

Are you going to use any fancy thermal coatings to mitigate under hood heat?
This is such a drool worth project! One that I would never be able to undertake these days. I can live vicariously through Motoiq.
We are going to use a few different things, figuring it out now!
Oh… I smell an article out about the various coatings and wraps/blankets out there and the science behind them…
Lately I’ve seen cerakote being advertised a lot for underhood stuff. Even going as far as saying it’s equivalent to traditional thermal coatings. I’m not sold.
Then you have the DIY stuff from techline and eastwood. You have Swaintech and their white coating, the original jet-hot brand, not to mention local coaters like Embee and your local powder coaters..
I know ceracote is awesome on guns, it’s the most durable and abrasion-resistant coating in the gun world, it doesn’t rub off on holsters too easily, and is almost as tough as a plating. Doesn’t seem to burn off either although most kinds of guns we can buy don’t stay hot as long as car parts! The super air-cooled Porshe we did a video on a few weeks ago has a lot of ceracoted engine parts that still look good after a track day.
Very interested in the ETS G35-1050 kit for my R35. It has a big advantage for me having a recirc dump. Not many builds I’ve found using it or dyno’s would love to see more info!
Thank you
