Twin turbo dual exaust yaris 1NZ-FE setup?

[CtrlAltDefeat]

I was reading about turbo 3-cyl Daihatsu Charades and suddenly had a thought. The turbos on those things were pretty small... I wonder if you can run 2 small turbos off 2 cyl each of the 1NZ-FE? Like 2 turbo 2 cyl engines on a single crank. If setup right, I think the opposing cylinder would be on the power stroke while the 1st cylinder was on the exhaust stroke. I'm not sure if I'm explaining it properly so i snatched some pics off the web and drew it. Forgive the craptacular picture but I'm in a hurry and my 'shop' skill sux. Obviously the pipes would have to be equal length and as straight as possible but I think 2 Y shaped headers and 2 Y shaped turbo to to intake pipes would work.. with each turbo only working with 2 cyl I think they could be small enough to fit in the engine bay and still make plenty of power... Just some random thoughts of a engine noob... If this makes no sense what so ever, please let me know, and why. Seems like it might work pretty good...

first things first... move this to forced induction!

LOL aye aye cap'n

I like the idea... with some teeny tiny turbos it could be done...

But, is it really necessary? seeing the results Garm got with his small turbo, it's pretty darn responsive and good for about 180whp, i don't think the added complexity is really required... but for bragging rights, can't touch a twin-turbo Yaris

Yea, I can see the twinturbo badge I'd slap on the back now *goose bumps*
(oh and sorry for the mis-file for the topic...)

thinking about it, I wonder what will happen to the turbo during the compression and power stroke when both (ok ok all 4 ) valves are closed... must be ok, since I'm sure there are turbo 2-cyl engines out there... aren't there?

if you want to spend all of the money on fab work and use GT12's and be unique, thats cool. But if you want the engine self imploding on itself and tearing a black hole in the space time continium thats cool tool....

geez it's only a 1.5L... I think you'd need at least a 2.0L to damage the continuum

the VAG 1.8T has already proven it can.

It's been done on a 1.8 miata.....http://www.miataturbo.net/forum/t17065/

its gonna open a black hole..hmmmmm.

I can't find pics of it now.....but a while back I found a pic online of what looked like a supra motor that had 6 turbos on it....It didn't have an exhaust manifold since each turbo was bolted on to the block itself. They were super tiny turbos.

Well I've seen alot of 1.3 liters do some pretty nasty things... Mine is only ~350hp right now. Only wish it got the fuel efficiency of a yaris, or even my full size Chevy.

As far as the twin turbo goes, that's interesting, It would be neat to find out how well they would spool up with the pulse like that, not too sure about the efficiency on it.

I'm this close to offering you money to show me pics of this...

So, if twin charging is possible, would it be possible to have the said set up along with a supercharger? Massive complexity! hehehe.

twin charging and keeping the intake separated doesnt do much, it also creates a power imbalance between the cylinders as the turbos will deteriorate at different rates. If you twin, then unify the intake side of it, no sense in keeping it separate. The turbine during the compression stroke will continues to spin but slow a bit due to inertia no harm done.

My question is, what is the point? I mean yeah it sounds cool on paper, but you are adding more weight then it is worth. The P to W ratio of a single compared to twin doesnt make sense, the weight cost of a larger single compared to a twin will be about a x1.6 difference due to the weight of the housing's on top of that you are running more weight with individual exhausts.

If you are doing it just to be unique and to say you did it, then go for it!

Here's 4 turbos.....http://www.gizmag.com/go/5227/picture/20323/

I guess I saw wrong....But still same concept....1 turbo per cylinder.

off topic but, its a fold-able boat link from the previously posted link....

ok.. maybe scratch the separate intakes, but hows about a traditional twin turbo? Sequential? Parallel? If it's works well, a twin turbo yaris would be the shit...
