Twin Turbo

[Weyro]

Was wondering if anyone has ever ran a twin turbo setup on a starlet.

I was thinking that if you ran 2 ct9 turbos at 1bar each, then you would effectively have 2 bar of boost and quicker spool than running 2bar on 1 big turbo.

Oh I've been thinking about this for a while but more of a ct9 and a gt28 combo so you have low down acceleration with big top end

No need for a gt28, maybe for a gt40 lol, Theres a thread on tgtt about it, i think they came to the conclusion it wouldnt be worth it.

Would look epic to be fair

If running one small and one large it would have to be ran in sequential configuration otherwise the smaller turbo would end up over rev'ing and destroying itself. Tbh it probably can be done but you would have to sacrifice power steering, air con etc to make space. Plus essentially you would have to run two manifolds with runners 1 & 3 and 2 & 4 linked to tbe turbos. Which is a waste of time since this would be easier to run a twin scroll setup.

The engine is really too small to utilise a twin turbo setup.

Think sequential would be too complicated for my skills lol.

But parallel ct9's would be fun to see the outcome

ive thought about this before but i dont think you'd have enough space.. some people on here struggle to fit a single turbo into the bay!

Where there is a will there's a way !!

Wooo broke the 1000 post mark, beast

Surely you wouldn't have to mount the side by side, one could be lower than the other?

Twin 5e engine one in front ct9 one in the bk biggest Mofo u can get your paws on 4x4 with standalone

Go for one turning ang one burning set up. Compound charged supercharge and turbo gives low down power fast spool and good top end power lancia delta did it years ago

[td04 turbo]

So the turbo gives faster spool boosts the super charger quicker

[Addymk2]

I'm sure someone tried this on TGTT years ago. Because there were only 2 cylinders powering each turbo it ended up being laggier and a bit shit. Compound charging would be ideal though and that's getting more and more common! Ct9 blowing a beast ;-) sounds like a porno

No supercharger spools turbo up faster no other

Me and keiran have looked into this at work,was looking at twin setups off Toyotas (Supra/Soarer) really wouldnt be worth while in a starlet.

[keirz]

many people with twin turbos do a single large turbo conversion. Cant see a point in twin other than being different. Two ct9 at a bar each will prob equal a single td04 at 1.4

[jimjam]

Would look pretty cool in the engine bay haha

[Simon]

Can't remember the guy's name that had the cruise kitted Glanza over on TGTT but he was hill climbing with it and was looking into compound charging. don't know if he ever got it done though haven't heard from him in a while.

[Ricky@Race-Tech]

This would spool worse than turbo's already out there and it wouldn't give 2 bar, it would give 1 bar with more flow.

Compound charged is the way to go, but probably not on a starlet. We have done it on other cars. But on a starlet kits like our GT28 kit spool up great and make lots of power anyway.

[Xpect]

An efficient Twin Turbo setup could only be achieved by copying the setup on the Supra MKIV. Would give fast spool and rather big power without lag.

[Addymk2]

The supra could do it because effectively 3 of the Supras cylinders offer more displacement than all 4 of the 4EFTE. Über lag. As I said earlier, compound charging would be pretty cool but a lot of effort.
