I always hear about guys going to a S5 Turbo instead of keeping the S4 Turbo on..Now my question is: can it be possible to run One S4 Turbo Per Rotor?..sort of a Dual turbo setup?..I am an N/A guy since I got an Rx7 and Frankly Know **** about the Workings of a Tii Setup(but Will next year as I am Building an engine for spring)..so I just thought with all the s4 turbos kickin around then maybe someone has made up or thought about a Twin turbo S4 Turbo X2 kind of setup..Thanks guys and please no Flames!..just Info or ideas would be appreciated..Cheers,STYX.

Seems like it wouldn't spool very well. And it would be hard (impossible?) to mount them together and route 2 downpipes, 2 oil supplies and 2 intakes in such a small space. Totally not worth it/possible IMO.

Seen it done before....just mainly for braggin rights. the 7 i seen was at a car show in Dallas and it had two rather small turbos, smaller than stock and he had a y-pipe for the turbo inlet ducts and he had two 2.25 inch down pipes y into a 4" exhaust...one tubo was mounted slightly forward and up than the other...he had plenty of room too but then again the had no AC, PS or emissions so that clears up tons of room

BTW they change to s5 turbos because the wastegate port on the s4 turbos are really small so with an exhaust you will boost creep like crazy...mine spikes to 13psi quiet often....thank you 660cc secondaries haha. the s5 turbos work rather well keeping boost down to around 8-10psi

It's been done.
The turbine side (A/R) is way too big for such an application.
Response gets thrown out the window.
