#2 - The other one goes before the boost regulator that goes to the wastegate.
Make sure you have a boost regulator on !

fyi SPOautos did not dyno at 470 at the wheels, he dynoed at ~427rwhp.
and since i've been a passenger in a couple of bnr stage 3 fds, i can say that it would be quite a trip with a 20b. Heh.

Sorry...but his (SPOautos) were actually lower then 427rwh......more like 412 or something.......unless he dynoed recently.
Ted is correct......the restriction on the twins are in the exhaust manifold/housings......no matter how big you go with the compressor wheels !!!!
You reach a point were you're simply choking the motor.....remember, added airflow adds to added exhaust flow.

Hello All! I didn't know there was a market for 20B twin turbo upgrades. Let me know if I can help any of you guys out with the turbo end of it. I am sure we can design you an efficient set of turbos...

If you are going to try the lines I am running. Try it at your own risk. A boost control is needed, as most of you knew that. I blow my turbos at the track the first time I tried it and I had the controller set for 15psi and for some reason it went way past that. But once you get it set right it works perfect. Right now mine will hold at 15psi as long as I want it to. But start at 10psi to see if it isn’t going to go past that.

RE-Amemiya in Tokyo quote that the 20B powered Cosmo is good for 450hp at the turbo's max flow. I don't remember the boost level they where using but wouldn't expect it any higher than 1-bar as reliability dies in the **** after that.
They quote if you up-grade your Cosmo to a sports exhaust, high flow intercooler, high flow intake & RE-Amemiya ECU. You can get 450hp from the engine. They then say that if you want to go higher, then you will require a single turbo conversion kit
