so have i got this tright,
the inlets go into the top of the engine in the pic , through two valves, one one either side of the head from left to right as we see it,

then the exhausts exits via one valve each side to the two turbos,

if so then we are looking at two different engines there,

yeh, sort of like two head mashed onto one block?

One head
4 pot
4 combustion chambers

just a bit clever

isnt it just opposed inlets to keep the head temp down rather than having 2 red hot ex valves next to each other?

That design is clever....
expensive, complicated, but clever....

Schrödinger's cat - so which one am I ???

Well each turbo is fed by its own set of exhaust valves by the look of it, I guess you can get away with smaller primarys and increased gas velocity this way?

it runs 2 small turbo's and closes off one turbo at low rpm, giving the 2 litres feeding one small turbo this spools it up realy fast and when the desired boost level is reached or it goes above a certain rpm the second turbo opens up to provide yet more boost and allowing more exhaust gasses to flow, its a very clever way of doing stuff but mega complicated, the supra, aristo, skyline, the tt soarer and a fair few others use a similar system but only having 4 valves + 2 ports per cylinder its alot simpler

The only sequencial twin turbo set up I can think of is the RX7.

Really? Didn't know they were sequencial.

yip, if you get the opportunity to drive one they have a very distincitve power delivery :) there is a valve in the hot and cold side of the "rear" turbo that blocks it off so all 6 cylinders feed the front turbo untill a predetermined boost / RPM point, where the valves open and the second turbo spins up.

Legacy GT (and a few other variants) is twin sequential turbos too.

This is the car it was designed for the Lancia ECV Group S.

Also after reading this again. Looks and sounds a lot like Vizards Poly Quad Head effect. Re-helping out swirl charge.

im a bit confused now, are you saying that the digram is a sequencial setup?

from my understanding id sat it wasnt, but i stand to be corrected?

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

It looks like it could be, there is a big actuator on the end of the left hand turbo to bypass exhaust gasses until it is called for, there is also some kind of valve on the outlet of the left turbo to stop the other turbo back feeding through it when it is not making any boost.

my bad brett , never noticed the valve after teh left turbo :)
