Well, as I have said earlier, there is a new version of the Boosted Performance twin scroll turbo kit....
Before I get to the details, I would like to thank this community for their support right from the beginning. It was great to see a positive response from car enthusiasts like myself when this kit was first introduced. As most of you know, my goal is to make the best turbo kit on the market, and have the best support possible behind it. I am not alone in this quest, as it is clear to that the guys at F.I have been doing the same thing, and also have a fantastic product available for you all. So it is great to see that I am not alone when it comes to putting a great product out to market.
I must also thank Mitco39, a local member who happened to be my second 370Z turbo customer. He was more than happy to bring his car over and leave it with me for three days. As a result I was able to achieve my goal in making the kit simpler to install.
There is a couple of reasons for this change. First is the install...and the feedback I received from current customers. A couple of you guys had a hard time with the installation of the 45* silicone coupler that goes directly on the turbo...and yes, it is a tight fit. This has now changed, and the new routing makes the install much easier.
The second reason (a result of the first) is the turbo options that will be available with the newly redesigned piping. With the new manifold the turbo sits at a slightly different location (very close to the previous). This allows me to use turbos that have the SP (S ported) compressor covers. These have a 4" inlet and a 2.5" outlet (vs 3.0" inlet and 2.0" outlet).
This opens up the doors for the new Precision GEN2 turbochargers like the all new 6266 rated at 800HP vs the old which was rated at 732HP:

As you can see this turbo is only available in the SP compressor cover configurations, so it was not compatible with the V1 of the turbo kit. There are a few more turbos that Precision is working on, but those won't be out till later this year. These will also be large turbos, and should only be considered for those who plan on building their engine.
Now to the recent changes.
If you recall, when I first had a donor car, I really wanted to route the IC piping on the driver side, but could not figure out a good way to do it. I then moved on, and figured out a way to push it though on the passengers side, and that works fine...nothing wrong with it, just a bit tight when installing.
It turns out, that if one moves the electrical connection on the starter by 180 degrees, enough room can be created to push a 2.5" intercooler pipe between it and the engine mount. This mod is very easy to do, loosen up an easy to get to 12mm bolt, spin the cable around 180 degrees, and you are done. Takes about a minute.
Here it is with the protective rubber boot, spun 180 degrees:
Because of this small modification the new plumbing looks like this:
Going in front of the OEM engine mount: (if you have an aftermarket engine mount, there will be room to spare since they are smaller diameter)
90 degree coupler looking from under the car, towards the steering knuckle:
T-bolt clamps are very easy to get to:
And over to the turbo:
On the floor it looks like so:
Now, since I had to make a new manifold to change the turbo location I went an extra step. The manifold is now build out of SCH 10 pipe. This pipe has a wall thickness of 3mm and the is essentially now "extreme". It weighs twice a much, but it is also twice as strong. There is nothing wrong with V1 of the manifold because proper welding techniques were implemented (back purging being the most important). The V1 of the manifold is just fine, and is track proven on the 350z platform.
Half done:
Here you can see the difference in wall thickness between the old V1 piping and the new V2, the new is almost twice the thickness. :
Finished product:
Mounted:
Clearance is still fantastic, and the lowest part of the turbo sits above the front sub-frame, and higher than the oil pan:
Port matched on the T4 flange:
All up:
Old compressor cover vs. new:
New turbo with larger air filter:
As a result of all this, the kit will now come with a oil thermostat, and two oil lines. One to the standard 30 row oil cooler and one from it back to the thermostatic plate:
