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?

[bloodrain]

well guess i might as well be the first to say it. Anything is possible with enough money. Is it smart, probably not, best bet probably would be to upgrade the turbo.

[scothaniel]

completely pointless

[celiman05]

why would that be pointless?

[celicaGT96]

most twin turbo supra guys get way better results swapping over to a really good single turbo rather a twin setup

[tigernate29]

Not to jack the topic with something non-celica, but did anyone see the article in the FEB. 2006 Modified Magazine of the twin turbo Ford Focus. 2.3L Duratec I4 engine making an estimated 350-400 hp. It may be worth a shot to try a 3s-gtte. It would be something that no-one else has. Good luck.

TT 4cylinder is pointless IMO. the SRT forums have a TT. They are using 2 diff sized turbos..1 smaller one to spool up quickly for the lower RPMs and a bigger one to spool up at higher rpms. to me, waste of time and money..use the same amount of $ to build up a powerful 3sgte.

also, no you couldnt use a supra TT setup. The supra TT has a line6 manifold with 1 turbo at each end. IE 3cylinders per turbo. If your goin 2 go with a TT 4banger..ur gonna have 2 make the manifold the same way..2 cylinders per turbo..but that also means ur probably gonna get some bag lag due to valve overlaps.

[celiracer]

Agreed. TT is pointless. Usually people with a twin turbo'd car upgrades to a single turbo. And get way better results.

^ i saw that s**t, that damn focus was crazy!

[anubis0108]

ya i twin turbo setup is really absolete. TT's were a ood idea bac in the 90's but todays turbos are good enough that you wouldnt need 2 turbos to spool for higher and lower rpm's. yea its true most guys who have a supra ditch the setup for a single better turbo. to me TT setups are a bit out of date, but if ya go the money to spend thousands of dollars on two turbos by all means do what your hearts desire

[lilsteeg]

TT setups are good, on v6 engines or v8's, on an I4 no, and yess the supras with the single turbo are a hella lot faster than TT supras

[CilverSeliST205]

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)

ditch the twin turbo and go Twin charged......its been done before pretty smart idea too only needs one exhaust manifold...

supercharge and turbo all in one

[celiman05]

ya that would be SICK!!! im just getting some new ideas for my next project. thanks for that one.

You beat me to it. Something like that would be hot.

[burneeed]

That would be fun... thats kind of like the supercharged sti... that thing was nasty.... get a blower and a turbo that kicks in around 4 grand

[gamesteristj]

A guy in spokane has a twin turbo mr2. It's my boss's friends.

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

[bloodrain]

the ONLY advantage of having a TT setup is... it sounds more aggresive. "My 500 horsepower, twin turbo pinto" vs. "My 500 horsepower turboed pinto."

Pinto Fo Lyfe.

[playr158]

the advantages are i could run a larger turbo for good top end but have a supercharger with a small boost level say like 8psi to spool up my larger one off the line the benefits are amazing....
