Re: (MidShipCivic)
is it just me, or is each turbo getting fed by 4 pipes each from the exhaust?(which means 8 pipes in total...but 2jz is 6 cylinder??)
also im not very good with sequential turbos, whats the thoery behind it? one turbo spools, then it sends boost to the second one?

Small turbo for boost response and then big turbo for big power .

Re: (PolishSasquatch)
Each turbo is fed by 3 runners. The fourth runner of the collector goes to the 60mm Tial gate. There is also another runner coming from the "log" section of the manifold between the 3rd and fourth runners that goes to the 60mm gate. Control of this system is very important so we made sure there will be no boost control problems with plenty of ways for exhaust pressure escape.
The turbos are the same size. You cannot run different size turbos with a sequential setup, they need to be balanced. A compound turbo setup can use different size turbos where on blows through the other.
