What 4 banger has twinturbo

:gives: I just want to know and i cant find anything...

Im thinking of making a ka24dett using 300zx turbos..

[OptionZero]

Apexi Drag Integra =P

Why TT?

[twitchy]

two small turbos instead of one large one means more efficiency and less turbolag

nice if you could fit it

[berngtr]

the suburu leagcy B4 comes stock with a 4 cyclinder twin turbo set up

[CustomS14A]

A friend of mine has and most of the things on the left side of the motor gone and with all extra room you can easily fit a twin turbo setup...The only thing i would have to find a turbo shop to make custom headers and piping plus i got two turbos off a friends 300z so if i have them might as well use them...RIGHT

heres pic of the tt sr, since the gallery is down.

Why TT?

The cars top speed would be reached fastrer also better 0-60, 1/4,
Ka24det 15psi 300hp 350tq most of the time
ka24dett 5psi+5psi less lag i guess a 2.4 liter motor would be a good tiwn turbo car.

A wise man told me that the ka motor buleprint was going to be a turbocharged motor...

The JDM 1G-GTEU (2.0 Twin turbo) came in the 86-87 Toyota Supra aswell as old Soarers. Not Many People even now about it. It is a vary rare engine on US shores. It is Very hard to find parts for it. There is one on Ebay right now that is 5sp with 61k miles, the reserve is met and its at 500$ with a 24hrs left, if anyone want to step out side the box, you can have a Twin Turbo 2.0 240sx or 200sxtt. Just go type in the engine code i've listed on ebay and you'll see. Or type it in google, an see how much info far aswell parts you can get for it. I do know it has 210hp and no one tunes it. But im sure if you add a FMIC, bigger turbos you can run 300hp, just hope nothing brakes.

[OptionZero]

I'm not a turbo expert by any stretch...

but isn't a TT set up more traditionally used on engines with a "V" setup...V6 such as the VG series, or the 3000GT (Gto)...or a Corvette....

The simple fact being you can put one turbo on each bank of cylinders

on the other hand, with an i4...you have alot more cramming to to get the twin turbos in a smaller space?

Are two turbos more efficient or less?

I imagine its also dead weight...
I understand that smaller turbos spool faster, so two small turbos will get boost faster than one big one tryin to make the same power...

What are other pro's and cons? aside from the simple fact that more turbos...more poarts...more$$$

[stp9154]

I'm not an expert neither. I'd like to know if SR or KA would create enough exhaust for a twinturbo set up? And why not go with a sequencial set up, one small and one big turbo? Good luck with the project tho.

[twitchy]

Saab use a v6 with one turbocharger fed by only one bank of the engine.

[speeddreamz]

Why use a 4 banger for a twin setup? a single I think would be more efficient even with turbo lag. Maybe if the setup was sequential it could yield some good power. How much power are you actually trying to get? or is this thing just trivial for kicks/

Just my 2 cents, maybe im a dumbass.

[CustomS14A]

I would like to try this because it an undone mod for a ka...
I belive that there is enough room under the hood...
With this setup I hope that my car will at least run...

[twitchy]

still love to see a KA supercharged

[ICKY]

Haha. Superchargers are for muscle cars! Didn't you know? Naw im just messin. but that would be nice to see a super charger kit for the KA. I'd definately give it some thought. OT, i'd like to see a katt, sequencial, AND run 9's in the 1/4. That would be hottness.

I'd like to have all the money it takes to do the project......I'd just build a KA block strong enough for high boost and a large turbo, spray it till i build boost and take 9's.......But thats just my thoughts on the matter......

Balance and blue'ing the block alone would be too expensive for me to justify......

:blah:

[FallbrookS13]

twin turbo is a waste. why do you think everyone converts ther supras and rx-7's to single turbo. and a twin turbo 4banger... thats just a rediculous idea i think, would be a headache to tune

[okashira]

WOW.

-faster then a single turbo making the same power? ok...

-please explain why your 'twin 300zx turbos' makes more torque on a 2.4L then it did on a 3.0L

-5+5 doesnt equal 15, try again. you're wrong anyways.

[okashira]

two small turbos instead of one large one means more efficiency and less turbolag

please show me proof of any of this. or did you just make it up?
i can show proof otherwise.

I found this a while back, Twin Turbo SR (http://www.imagestation.com/picture/sraid110/pa9a139f84c74d6235a37e9f451394a20/f91a18fa.jpg).

Finally someone who isnt knowledgable, but instead of pulling shit out their a$$, they actually ask questions instead. it seems alot of you could learn somthing from this guy....


to answer some of your questions :)

yes twin turbos are 'normally' reserved for V-engined cars. single creates a bit of a exhaust piping nightmare and TT CAN offer faster spool for these engines due to heat loss in the long manifold piping for the single car.

No, two turbos are not more efficient then a single turbo. simply due to the fact that larger turbos are more efficient then smaller ones.

The ONLY way you could POSSIBLY gain SOME advantage with a TT inline-engine car is with a sequential set-up. Direct 100% of exhaust flow to a single turbine at low RPM, spooling it up, then opening a valve that directs 50% of the exhaust flow when good boost/power is reached from the first to the other turbo (possibly a larger turbo).

Some problems I can think of with this
-tuning both engine mngment and exhaust valve timing...
-creating such a setup without excess backpressure
-piping nightmare
-more failure points
-still using two turbos likly less efficient than a single larger turbo.
-$$$$

[OptionZero]

...only sending 50% of the exhaust gas? I understand you neeed to keep the 1st one spinning, but the 2nd one getting so little of the charge..wouldn't it seem like it's pointless? Its a bigger turbo, takes more energy to spin, and you're only sending a little air...

yeah, a 2.4L is pretty big for a 4cyl...i just seems like alotta work for little gained and potentially much lost?

I keep forgetting not all TT's are sequential...

is this right:
supra, rx7 are sequential
3z, 3000gt, simultaneous?

Now what *I* am interesting in seeing...more twincharger setups, like the one HKS made for the 1st gen Mr2....

my friend is still dreaming about callin HKS up and havin them dig up a setup for him...
Supercharger builds instant power, transitions to a turbo...of course tuning is a bitch

It's on a sr why not put two turbo on a ka the only thing that might get in the why is money for custom parts and steering parts...


Try new thing not the same old bullsh*t

[andrave]

I'm trying. Have been gathering parts. should have it done by July.

[Tictakman]

a Noble is a twin turbo car that has sequentials.

Zak

[DuffMan]

For parallel setups 2 turbos have less moment of inertia than one bigger turbo, but running 2 turbos off only 4 cylinders is not good for spool because at the lower rpms, the pulses of only 2 cylinders are too far apart.

So the small amount of spool improvement from better efficiency would be lost, and it would be basicly pointless unless it was a motorcycle or a racecar that would never see below 4000rpms.

A sequential might work better.

[misnomer]

If the man wants to do it, let him do it. Research the sequential turbo setups of the RX7 and similar motors- I can't think of how a simultaneous setup will benefit on an inline engine (particulary a 4cyl). Shit, I can't think of how it would have advantage over a single turbo setup. . . wider power band maybe. Everybody's argueing about efficiency when his car will still be be quicker :P

[Red]

I say go for it... Your only .2 smaller then a RB26TT why not have a KA24TT

And there has to be a good reason to make a SR20TT its .4 smaller... or .6 smaller

[OptionZero]

number of cylinders matters

[twitchy]

please show me proof of any of this. or did you just make it up?
i can show proof otherwise.


well to start, porsche and audi both converted to a twin turbo setup from a single turbo to recuce the jeckyl and hyde personality of the engines and reduce turbolag.

Its just physics

Ladies and gentlemen id like to welcome Shakira, our newest in house turbocharging expert. :fawkd:

[OptionZero]

well, when making upwards of 400-300 hp, when you need lots of boost, a TT set up might help kill lag, but for a 4cyl makin less the 300 like what most people here would shoot for...TT seems unnecessarily complex to me

not to mention this is Porsche and Audi, using 6 cyl engines, and an OEM manufacturer with the resources to test and design this shit perfectly. Adding a TT setup to a car not designed for it from scratch...fun, probably trick and neeato...but not cost efficient or easy

How does the flat 6 layout of the Porsche affect things?

[twitchy]

yeah agreed, i mean two very small turbos might be a benefit to a 4 banger, but it could be easier on a flat four or a V4 if one existed, see what I mean?

flat 6 affect things like what...dont follow you,?

I hate to break it to you, but those porsche and audi engines aren't inline.
reasons for this addressed in my post :rolleyes:

not a turbo expert, just a lil common sense.

Same thing as a v-6... the exhaust outlets for each 3 cylinders are significantly far apart.

learn how to read turbo charts email them for overall turbo specs good

There is a shop in LA that takes all of the engine space runs it through a computer and makes custom headers downpipe and exhaust...

IF YOU BUILD IT HE WILL COME...
