twin turbo????, hhmmmm i wonder Options

[celiman05]

just a really crazy idea i thought up. would it be possible to twin turbo a 3sgte? could use the setup from a TT supra maybe. what do you think would be involved in trying this?

I have to disagree with you guys.. Toyota did build a dual-stage turbocharger that bolted onto ONE manifold. In that set up the smaller turbo spooled up quick to give you a kick in low rpms, when the small turbo boosted to its reasonable efficiency limits, flapper valve would set off the bigger turbo.


Single turbo setup better? if you can have a spool-up of ct20b with max output of GT3040? nah!

only downside of such twin setup is its price ($$$$$$$$$$)

and BTW on 3sgte 2 manifolds for twin-turbo is a poor idea

and i suspect that the reason why people with supras get bigger # with single is because they replace factory TT with single turbo unlike people who push factory TT to its limits, now if someone has enough $$ to waste for 1000 rpm earlier spoolup and upgrade to aftermarket TT they would get better results than single turbo setup (its just not money efficient upgrade)

there is no more need for a TT setup due to the new variable geometry turbos, in essence the turbo is smaller at low rpms, then opens up more at higher rpms to allow for more boost, so the TT setup is now outdated on an I6 due to that, and the price
