Not an MR2, but I figured you guys would enjoy drooling over this just as much as we are

We have been working on a fairly extensive compound turbo setup on a customer's Supra for the last couple months. We've kept it under wraps for a while and will be slowly releasing information on the build. There are a few things being done on this car that make it the first of it's kind in the world. Keep your eyes peeled.

So far:

* 3.3L VVTi 2JZ-GTE built engine & head
* Hypertune large port intake manifold
* Direct port methanol injection in second fuel rail
* Methanol injected pre-turbo and post intercooler
* Custom setup Motec ECU and logging/monitoring tools
* HRE Wheels
* Custom Penske coilovers
* Custom EMSPowered compound turbo kit
* Comp Billet Ball Bearing 6465 small turbo
* Comp Billet Ball Bearing 8283 large turbo
* EMSPowered custom made twin-scroll equal length manifold leading to the small turbo with high precision CNC machined head flange
* EMSPowered custom made up-pipe leading from the small turbo to the large one (we've nicknamed this guy the octopus, you'll see why when we post photos of it)
* Quickspool valve on the large turbo
* EMSPowered custom made 4" v-band downpipe
* EMSPowered custom 4" midpipe with 4" boost actuated dump
* EMSPowered custom 4" to dual 2.5" y-pipe to join to factory muffler for street driving
* EMSPowered custom 4" b-pipe and muffler for race days
* Ceramic coated downpipe and full exhaust
* Ceramic coated both exhaust manifolds
* Ceramic coated turbine housings
* Custom built inconel heatshields for manifolds and turbine housings
* Two 60mm TIAL v-band wastegates
* One 44mm TIAL MVR v-band wastetgate
* EMSPowered custom made 5" intake pipe & filter with v-band at the turbo connection
* EMSPowered custom made intercooler with hand formed end-tanks and Wiggins clamps everywhere
* EMSPowered custom made upper and lower radiator hard pipes with Wiggins clamps
* EMSPowered custom made oil catch can
* EMSPowered custom made coolant overflow
* EMSPowered custom made power steering reservoir
* EMSPowered custom made coolant swirlpot
* EMSPowered custom made fuel filter mount and skid plate
* EMSPowered custom made methanol pump mount and skid plate
* EMSPowered custom made methanol fuel cell in trunk area behind rear seat
* EMSPowered custom made battery tray and fuse box tray in trunk area
* EMSPowered custom made mounts for Penske coilover reservoirs
* EMSPowered custom 4 point roll cage built to exceed NASA specs
* Custom hidden/stealth parachute mount built into trunk floor
* Oil cooler custom mounted with custom built EMSPowered duct/shroud
* Wrinkle black powdercoated water neck and radiator pipes
* Wrinkle black powdercoated charge pipes
* Wrinkle black powdercoated intercooler endtanks
* Wrinkle black powdercoated radiator endtanks
* Recaro leather racing seats
* Custom racing harness

There is lots more being done to this car that I'm . This is just a short list of some of the more important performance modifications.


Some photos:

Damn, impressive. Can't wait for some numbers/vids.

please give me that engine! hahahah

There's a third wastegate not shown in the photos in the first post. Here are some more photos that may help show how the manifold/turbo/wastegate setup work:










Also, here are some various photos taken along the build process:

This thing should be a quarter mile monster...But i bet a t6 would still eat it up on the freeway .. Still nice to see some new things happening with the 2j. What is the story internally? Also what tranny are you guys gonna use? v160?

Stock 6speed transmission and differential. This car is being built to be an all around top notch performer, drag racing, road coarse, standing mile, and of course highway runs. The owner will be attempting to set a few world records with once's it's finished

excellent fabrication work bak. looks amazing.

Too much awesome for one thread.

Thanks guys.

That exhaust manifold is ****ing maze for me to try and follow from those photos.
I take it compound and sequential are the same in this case for the turbo set up?

edit

Got any photos with out the turbos hooked up to it?

I fapped....

Is all the welding done in house? Such beautiful work! I hope to see some videos of it.

Wanna make me a manifold? LOL. Jesus. That's one nasty monster... and it's white. Do want.

Sequential and compound turbo setups are totally different. Let me know if you need a brief description and I'll do my best to explain the difference. I'll look and see if we have any good photos of the finished manifolds without turbos attached for you.


Yes, we do ALL of our fabrication in-house. This includes custom one-off work like this, and also our turbo kits, manifolds and other products for the MR2/Celica/Alltrac/GT4


Sure thing, we build all sorts of kits. Let us know what you need and we can quote you a price. Check out our website and you may find that we already make what you're looking for. If not, let us know and we can make just about anything you can dream of.

Really?! Oh boy! Now I'm getting excited. I'll hit you up when I can and I'll def be interested in a quote. I'm looking to build a NA daily that performs well and can be autocrossed. Already almost complete on the suspension, I just need to finish the exhaust for the next step and eBay headers are trash. They do nothing for performance boost and are made from cheap metal.

I'm glad I stumbled across this thread

We can build it from mild to wild. Drop me a line when you're ready and we can start getting a build plan together for you.

my god!

more.

I feel I have somewhat of a rough idea of what your system is doing. Not being able to follow the flow perhaps is throwing me off. But when I try to follow it almost seems as if its both probably because of all the wastegates you have on it.


Orange is first inlet charge, brown takes charge into 2nd turbo, compressing it more and then purple takes the exponentially charged air through the IC past the throttle body into the engine.

Red Exhaust goes from block to first turbo, light blue it goes from first turbo to 2nd spooling it up, green wastegates dump to 2nd turbo for full powah.

Red Exhaust goes from block to first turbo, light blue it goes from first turbo to 2nd spooling it up, green it finally hits the downpipe.


Sequential

Series/Compound/Staged

You've got that mostly correct. So the benefit of Compound versus Sequential:

Here's a good graph to explain another important part of the differences (twostage is referring to compound setups):

Nekronos, I think you're flow was backwards

should look like this


Turbo 1 is attached to exhaust manifold.
Turbo 2 is attached to via exhaust of turbo 1 + wastegates 1,2


Air enters via turbo 2, is compressed and sent to turbo 1.
Air leaves, turbo 1 and goes through IC to TB.
Exhaust exits via turbo 2

Blue = intake air
red = compressed
pink = twice compressed
yellow = from manifold
green = exhaust from T1 to T2
