i like that this is posted in two spots so i can watch and like it twice.
Haha. Well thanks and I post it in two places because some people automatically skip this thread because it has LS3 info on it. That way if they just want to see the Supra Big Turbo information they can go straight there but this thread is for everything I'm working on.

We got it! Finally they were able to break through the issues with closures and limp mode. We got a full clean pull at 14psi and at 20psi. These are just baseline runs and we still have more psi and more timing to go for numbers. I can tell you it's making 550 tq before 4krpm which means this setup is going to be perfect. The twinscroll EFR comes on way sooner than everyone expected and I'm very happy with the result so far. Part of this is because of the 4" downpipe, external gate manifold design, and properly sized a/r housing.

Stay tuned today for power runs and to find out where the stock fuel system can go just on 100 octane. No meth, no nitrous.

Sound up and enjoy!

Loving the build and updates. Whats the specs on the tires (I saw the wheel specs) and drop? The stance is just right.

Thanks man.

The tires are 305-35-19 Mickey Thompsons and the front tires are the old rear tires (275's)
To be honest it needs 30 profile tires to not piss the car off and I'll eventually switch but all my money is going to finish this big turbo build. I'm not fully settled on the ride height because I might be heading to the dragstrip and try and get a solid 1/4 mile time tomorrow night if we can hit it hard on the dyno today and tomorrow. She has 10's in her now and looking for 9's. After that I will keep it pretty low for a daily driver setting.

I've started a separate thread just for the Supra. I just drove the car out to Full Race Motorsports last week and dropped it off for some upgrades. More to follow on that.

With the Supra in Phoenix with Full Race it has given me a good opportunity to get some things accomplished on my LS3 Twin Turbo M3 project. This weekend I was able design the fueling system and route my lines.

I have a local company that gives you all the AN lines and fittings and you cut to the correct size and install your fittings. Then you take it to them and they crimp it which gives it a very clean and solid seal. They have choices of all black, black and gold, blue and gold, and the Pep Boys special of red and blue. I will be going all black for my setup. The blue fittings you see in the photos is just for mockup.

I will be mounting my fuel regulator this week, finishing the turbo manifolds, and hopefully testing out my wiring harness from wiring specialties. I had a custom wiring harness built for a plug and play setup retaining AC, PS, and running an AIM dash.

I will update with more pics once I have the turbos mounted up.

Some updates on the M3 build while the Supra is at Full Race Motorsports for the next 2 weeks.

I finished up the turbo manifolds and turbos are in their final resting place. Fuel system is completely done. Wiring harness is in and have to finalize my locations for the coil packs.

Next up will be running oil lines for the turbos and then setting up the shifter for the TR6060.

I'm happy to have updates to my builds and thread title.

  • The Twin Turbo LS3 M3 is now running and will upload a video soon. Currently working on charge piping and clutch bleed line to get her on the road.
  • Sold the 2020 Supra and patiently waited for a 2021 with a pre-lock ECU. Just found one last week and took delivery over the weekend. This car will be tuned by Jeff Payn out of Colorado. I worked with him previously and enjoyed the process. The tune was spot on and the service was even better.
Great content headed your way soon.

That LS3 looks sweet! And it's that "LS3" over the subject that's gotten us to following this thread.

But honestly, we can't wait to have more updates on both actually
