Maybe, but probably the reduced exhaust gasses (only coming from 2 cylinders as opposed to 4) would probably cause some pretty serious lag and inefficiency unless he was running a smaller turbo (at least a smaller exhaust side), but then you run into the problem of not having much room on the other side (meaning you get spoolup, but lose on ultimate power gain). Most twin turbo setups are sequential (sp?) with a smaller turbo for the low ranges of RPM switching to a larger turbo for the upper reaches. Definitely would be cool to see how (if) he made it happen!

I'm with this guy, have yet to hear of any pro teams with $$$$$$$$$$$ up the *** building a twin turbo I4, and those Twin Turbo I4's that I have seen built have only cons and more cons... never out performing a single turbo setup in any scenario. Lets see a VIDEO! I won't even settle for a photoshopped picture.

Re: (db8xc1x39)
yea, i';ll try to get more info on this ASAP...im goint o try to see if its coo if i can go take a look at this in person...yea, i have heard the idea of twin turboing i4s for years, but every scenario has nuthin but cons and more cons...i wud love to see a dyno sheet for his engine, see if the twin smaller turbos power band compared to a single turbo'd B18...on other note, i read in a mag that sumone is in the works of twin turboing a WRX STi, and its goin to be sporting 1 of only 2 chargespeed wide bodykits in the states, cant wait to see that hit the mags

Most of you are thinking of it at set-up as 2 exhausts ports per turbo.
Think of it in series. You have two different sized turboes. One small for no lag, and one big for when the small one doesn't have anymore more push.
This will give you no turbo lag and awesome performance from forced induction.
This concept has been around for a long time. Just applying it is pricey.

kinda like the dual staged supra only 500 or so of those were made though

sounds like the super/turbocharger concept they useto use in the rally cars

Re: (db8xc1x39)
Definitely possible, but as mentioned before, there are far more disadvantages than advantages in this sort of setup. It's been proven time and time again that more power can be made from a well set up single turbo system than a twin turbo system on an I4 car such as ours.
It's analagous to having a turbocharger AND supercharger. Sure it sounds like a great idea, it sounds like it'll have massive power, but in the end, having just one and tuning it well will produce lots more power (and more reliably as well).
Not that I'm doubting what you're saying, but I would be interested in seeing pics as well, from a pure curiosity standpoint. I'd like to see how the exhaust is routed.

Re: (beaterman)
Ive seen a green LS with a twin turbo set-up at VMP during inspection .. Dude was pretty cool, and i gave him props for the TT set-up.. he hadnt run it yet, but expected it to run 13s non tuned that day.
I never got to see him run or hear about it

Actually, the guy on HMT made a twin-turbo LSvtec...and he built it in a week....and it cost him $700 all aruond (yay for fourty dollar turbos), AND it was in a CRX.
Just nuts stuff.

In Europe mini's with B16a's and even the B18c5's are quite common. The mini clubman is used. With some front end work and reversing the way the hood opens a B16a can be fitted. these mini's can do 0-60 in 5 seconds stock. (on a b16a)

Fitting a B-series engine in an old mini is tight enough as it is... adding 2 turbos and plumbing seem pretty much impossible. I would definitely have to see pics to believe it.
