New winter new turbo build
RESULTS at 8psi:

Well guys, the time has come. The winter (at least up here) has begun, so I am under the car again.
This is the original build thread: https://my350z.com/forum/forced-indu...brication.html
This kit that I am working on is not for me, but for a "customer" I guess you can say. It will be a bit different as I have learned a few thing when it comes to building a turbo system. I will point these things out as the build goes.
So first of I will start with the most importan things, new tools I have purchased.
Heart of the entire operation is the welder. This is an AC/DC high frequency machine. I sold my old one to my boss, and got this unit for $1600. I am supper happy with it, and once all the dials are set properly it almost welds byitself.
Second purchase is a new saw. I LOVE THIS THING. It is not your traditional abrasive cutting wheel, but a toothed carbite blade, much like you have on your circular saw. The cuts are incredebly clean and not one burr, so there is no wasting time cleaning the inside of the turbing. Never used one before, or even knew about it untill I saw it in a flyer. $500 later and it is now my.
I also went out and got a two bulb flourecent fixture. This beats any trouble light out there:
On to the new piping, once again I choose 409 stainless do to it's ability to withstand heat/corrosion and most importantly no cracking. This time around I am doing all the pre turbo plumbing with 2.5" piping. I found that the 2" crossover pipe was too small and restrictive causing my bank one wideband to read richer under WOT boost runs. This was bothering me for a long time, and the problems went away when I switched the 2" piping with 2.5". You don't see this on other kits because other turbo manufacturers don't put a wideband in the crossover pipe.
New turbor. On the left is my old Garrett T04S 60-1 turbo with a large S compressor cover. On the right is the same turbo with an "E" compressor cover. This will alowe me to tuck the turbo even higher than the old one. I have to say the old setup was plenty high and I have gone over Wall Mart speed bumps withough any issues. Turbo performance stays the same with a smaller compressor cover. One VERY IMPORTANT thing to note is that the compressor cover will NOT have to be modified. I changed the IC piping routing so that the turbo can be installed right off the shelf. This will allow for easy turbo upgrades down the road. A precision 6262 can also be bough with an "E" compressor cover and those are capable of 600whp on this platform. I know of a shop running twin 6262's with this configuration and made 1200whp.
I have been practicing my aluminum welding as well. It is very easy once the welder is setup, some 2.5" tubing, just needs to be polished:
All stocked up:
All IC piping will be aluminum ofcourse, and all the ends are beed rolld. This will allow for worry free high boost applications, as there is no chance of couplers to slip off:
Like mentioned before, the IC piping routing will be changed for the better:
Intercooler wil be different as well:
It will have a 21x11x3 core with 3" inlet and 3" outlet, also capable of supporting plenty of power.
We will see hot this goes, and how many of these kits I can make. If you have questions/comments chime right in.
Something else I should mention, with this setup there won't be any need to heat wrap any of the OEM wiring, making it a very straight forward install.

We shall see how it goes. If I can sell a few, you may have some competition in at the track from another VQ....
Now you just need to convince one of your G35 friends to come up here so I can test fit the kit on a G. Would be a nice discount tooo.

If you were going to do something like that, I'd seriously consider compound turbo'ing. That setup is ideal for it. run 1 turbo where he has it now and 1 where the STS goes.
One small one and then like a 80 or 90mm in the back. That would be soo sick

No, I didn't really push it and wanted to keep the engine from blowig up. Knowing that the turbo can push 60lb+ of air, I know that it can produce plenty of power.
Compressor map:
The intercooler is larger, and some 550cc injectors will be included so the potential is there. Just need a built block. There is also a Garrett Stage 5 turbine that comes in this turbo configuration, and that thing can push even more cfm.

you are liking your new Tig Welder? looks like an inverter machine. HOw is the manufacturer?
I have been thinking about getting an AC/DC inverter Tig welder. Been looking at the Thermal Arc 185 and also the Lincoln Invertec V205. The miller Dynasty 200dx is just too much $$$. What are your thoughts?

a garrett tech told me that each time you go down in size its roughly 10% loss in flow. S, E, the APS uses a B cover. the aps does not make good numbers. on built motors they max out around 500whp. the GTM upgrade is a little better, but i think its the E cover too. iirc, the intense kits use an S and get the best results. i cant swear to it because its been a LONG time since I had my aps kit, but the E cover does flow less than the S, thats why I changed mine to an S. your going from a .70 AR to a .50 AR.
