Has anybody ever tried that?

I guess I didn't explain my idea very wellSupra SONIC said:The supra TT is a sequential turbo engine, with two ct26's. Initially, only one is on for responce, then the second clicks on, sharing the exhaust, to get some real power.
Most people switch to a true twin turbo setup when getting larger turbos.
You can't have different sized turbos. Thermodynamic laws won't allow equal exhaust gases to go to each turbo, so that idea, which has been discussed, isn't possible.

Sorry dude, MKIV's come stock w/ CT20B's, not CT26's. MKIII's come stock w/ 1 CT26.Supra SONIC said:The supra TT is a sequential turbo engine, with two ct26's. Initially, only one is on for responce, then the second clicks on, sharing the exhaust, to get some real power.

Why is that?Simba said:And no, you can't use turbos of differing sizes in a sequential manner.
Aren't the latest gen J-spec RX-7 already senquential from factory?greensupra_87 said:I guess I didn't explain my idea very well![]()
I heard it has been done on the rx7, with some custom exaust mani, and valves, but it could be a myth. That's why i'm asking.
Searched and never found any info:dunno:
Because the larger turbo will out-flow the smaller one at the same pressure and stall it.ReI86 said:Why is that?
Thats what i'm talking about!^^^91 chevy s-dime said:ive heard somewhere that sequential is possible, both turbos spool up at the same time but the smaller one, is sped up quicker, making say x boost at Q rpms, but then its wastegate actuates and then the second turbo is still spooling up and keeps going up till it hits its wastegate. ya see?
i just read that somewhere.
and thats what everyone else is talking aboutSimba said:Because the larger turbo will out-flow the smaller one at the same pressure and stall it.
There's also a matter of differing backpressure created by each turbo, which is also on the list of Things That Are Not Good™.
