Project Turbo LS2/350z begins. Well I officially started the tear down today and will be getting ready to start building the kit soon. I first planned on using C6 manifolds but that idea was quickly shot down when I tried to put them on the car and they were pointing RIGHT at the engine mounts. So I went out and did it the old fashioned way with the truck manis. My setup will consist of the following:
-PT88 truck manifolds with a 3.5" downpipe exiting through the passenger side of the engine. Im having the flanges cut off the manifolds and vband rings welded in place. That will prevent me from needing to clearance the side of the car so the driveside can fit and its just a much better connection.
-Twin 38mm tial wastegates. Polished(I wanted black but my black tial 44 turned purple after a month so im gonna stick with ones that wont discolor)
-50mm Tial Q BOV black
-80lbs injectors with a redone return fuel setup using a magnafuel 4302 pump(I can always upgrade to the 4301 later on) using -8 to feed the engine and -6 as a return.
-I think im gonna try the speed inc TU3 (225/225) turbo cam with the stock 243 heads/intake for now.
-ebay 4" i/c with all alum. 3" piping.
-im going with a custom radiator but im not sure on the specs yet..im pretty much going to build the turbo kit then build the front end around it. Im going to be going with a custom rad. support to give me the room I need to make this happen
-Lingenfelter launch control/2step
-Some form of methanol not exactly sure which brand yet but im leaning towards alkycontrol just from the positive feedback ive heard on this form.
-2.5bar map sensor from a cobalt
..the parts list will continue to grow as I find things I need for the car. But as of right now I want to get the kit on the car and working and tuned for 4-8 psi and once its up and running perfectly im going to have the bottom end rebuilt and break it in on the low boost tune. One thing im not sure of yet is whether im going to be using my MAF or not. I hear so many mixed stories so im going to try and source a good tuner around here who knows what hes talking about and see what he says. I want to run 10-15psi on the street and maybe 20(or whatever the turbo will take) at the track. Heres a few pictures from what I have so far..
The typical turbo/soda can picture haha
Soda can IN turbo pic..(dont mind the FRCs..they were just laying on the engine to see if I liked them and I didnt)
Little peek-a-boo-shot
And so far heres the best spot I could come up for it to fit. There is NOT a lot of room in the engine bay so im limited in where I can put it.
just a random shot of the car at the track..(hopefully there will be more of this next year)

It went 11.33@128 with just a cam and a 75 shot..ON STREET TIRES. I went to the track with the 150 shot and slicks but the car just didnt wanna hook up so I didnt go anywhere. The car weighs 3100 EVEN (+/-20lbs) with the LS2 with no A/C and a 1/2 tank of gas.

I'm down for some rootbeer anytime 
Sounds like you just can't get enough...all the issues with the swap now boost on top? Gonna be a mean Z. Did you ever get the axle/rear end situation figured out? You'll need a SOLID rear end to handle the t88. Why not do the 4301 now, they're the same price and you won't have to worry about upgrading later. I'm running a 4301 primary and 4303 on a hobbs set to 10psi-streetcar. Hope all goes smoothly.

Did a little cutting today. Im going with a 22x19x3 radiator and the only way to have everything fit in this small space is to cut into the frame "arms" now they dont actually support anything except the headlights old bumper support which I havent had on the car for a while now so I can cut into them. The are still very sturdy and more than enough to support the headlights and the rad/intercooler support. I now how JUST enough room to fit everything nicely.
(this is the turbo side and unfort. theres not going to be enough room for an airfilter like on my last setup)

This should be a fun build to watch. I would be concerned about resolving your traction/hooking up issues as well. You can also swap in the Armada rear diff which is a 9" ring gear...They have a variety of ratios also. Something close to a 3.08 would be good. What size ring gear is the 350Z unit and ratio?
Did you fully gut the 350Z? I thought they were portly pigs?

The diff itself isnt the problem its everything around it. Its pretty damn big. I need to brace it better and im doing all suspension in the rear. As far as gutting no..only things removed are front bumper beam,spare tire and equip and AC.

Heres the manifolds with the 3 bolt flanges cut off and the vbands welded. They are welded inside and out. Now they dont hit the side of the car when I put them on.
