Finished My Twin Turbo Supra (7M) Last Night

It started out as a Blitz manifold but after a lot of welding I consider it my custom manifold. I use T25 flanges.

I want to run a filter for the top turbo, but no filter (or a very discrete one) for the bottom turbo. I want it to eventually look like a single turbo car.

My goal was to be a little sneaky with the turbos. I am dynoing the car tomorrow night. I need to spend all day today getting really familiar with the AEM EMS.

To assembly the whole thing is a pain in the a**. I needed about 15 different "custom" wrenches to assemble everything.
are the turbos identical? will they spool up together or seperately? would like to see more pics of the manifold also, if possible.

I'd like to note that all fabrication and assembly was done by myself. This means everything from welding to milling and surface grinding. Unfortunately I had no sponsors so it took an extra long amount of time to complete (>2 years I think)
Exhaust: 2x HKS GT2835R, Tial 46 mm WG, custom downpipe & exhaust (SS304), modified blitz manifold, AEM UEGO Wideband o2
Intake: 2jz intake mani, 2jz tb, garrett 24x4.5x12 intercooler with custom 3" piping.
Fuel: 720cc injectors, dual walbros (will most likely change this later because this was from my old setup), sx pressure regulator, AEM EMS
Suspension: Cusco Comp Zeros, JIC A-Arms (Upper), 14" front brakes with Wilwood GNIII calipers, MKIV rear brake setup, Volk TE-37s
Engine Internals: I don't want to give everything away but I do have a set of blitz cams and some other good stuff.

The turbos are identical, they will stool simultaneously (in parallel). I will try and take some pictures later but it is almost impossible to see anything. Runners 1-3 feed the first turbo and runners 4-6 feed the bottom turbo. The downpipes join together by the transmission.
The best upgrade you could do from here is adapt it to spool sequentially... which is kind of the point of twins on an inline motor.
Either way it looks like a lot of work and I hope you enjoy it!

sequential setup isn't the reason to put twins on an inline motor.
it's not that easy to just make a TT kit into sequential. Would take a new manifold and some sort of electrical control. Lot of extra lines and valves and stuff
anyway. that engine is really cool...

It's not? Maybe I'm missing something...
Is there a production parallel TT inline motor? (really asking, I don't know)
As far as converting it to sequential, all you'd REALLY need is:
- A cutout plate after turbo #2, blocking its exhaust until #1 spools and makes positive pressure in the intake manifold. (EGCV)
- Another valve of some kind on the compressor side of turbo #2, to prevent it from opening to the rest of the intake until it's up to the same pressure. (IACV)
I kind of think you could just put a very small pipe going from before the EGCV on the #2 downpipe over to the #1 downpipe and just let #2 have a tiny bit of "prespool" all the time, as a substitute for the bypass valve. The reed valve is simple...
and who says you need electronic control??
