when or is scion going to release the xb turbo charger?

I misread and gave you a search on superchargers, not turbochargers. My fault, it was completly an accident and I can't see how someone would get mad over it :? . Oh well. My fault. sorry!

Do a search. Here is one of many posts on superchargers...http://www.scionlife.com/forums/viewtopic.php?p=368038&highlight=supercharger#368038
He said TURBO not supercharger :x

My "B"!!

I've heard that GReddy is making one. Also, I've seen pictures of a prototype on a website (sorry I forgot the url) of a company that is trying to make one. So I guess it is only a matter of time.

Turbonetics has one...they had it in a lava at the Scion Exposed Philly...it may have been rigged to work and not a real kit but it was there...i even got to ride in it

HKS in japan makes one!!! Pretty hard to get i bet. :cry:

How much horsepower do turbo chargers offer? What is the major difference between turbo and super? Can't both hurt the car unless it was built for it? Doesn't it seem like too little gain for too much money?

Thanks, Vanilla!

don't look at the horsepower gain, look at the percentage gain, that is what is important, this is what you will feel...

well, look at it this way... your car weighs 2400lbs... you have 108hp... so you have 2400/108 = 22:1... so if you bump to 150hp... you'll then have 16:1...

so then let's look at some "hot" cars...

BMW
M3... 3400/333 = 10.2:1
330i... 3400/226 = 15:1
325i... 3400/186 = 18.3:1

Mazda
RX8... 3000/238 = 12.6:1
3s... 2850/160 = 17.8:1

Honda
Civic Si... 2750/160 = 17.2:1

many "boost" believers don't think that pushing 50% more horsepower is safe unless you plan on bumping the internals... opinions vary, but 50% power equates to about 7psi... regardless if it is supercharged or turbocharged...

but is 50hp worth $3000... absolutely... especially when you consider the tC setup is $3000 and it only gets you 40hp... but really it is just 33% more power... so the ratio goes from 18.4:1 to 14.8:1... yeah, 14:1 will generally be faster than the boosted xB, but you bought an economy car and you'll still get over 30mpg...

very informative. thanx alot for clearing some stuff up.

Yeah, nice analysis, mgithens.

Still get over 30mpg? Are you sure about that? I've driven small turbo'd cars before and they all seemed to suck gas (DSM products).

EDIT: and YES I stayed off the turbo to see what kind of milage I'd get (hard to do though!)

Same here. I did manage to get around 25-30mpg off boost cruising on the highway for long trips. Typically, I averaged around 17mpg though.

I currently drive a VW Passat w/ the 1.8T engine in it. It is running at 8 psi boost making 170 HP. This is probably only about 40 HP more than the normally aspirated 1.8L engine. Still, I manage around 24 mpg in city driving and around 33 mpg on the highway. Since I have owned the vehicle for a while now it is easier to "stay off" the turbo but I still tip in every once in a while. :D A turbo charged xB would probably lose a couple mpg unless you "tip in" to the turbo more than is necessary. I believe a turbo charged xB making around 150 HP would probably get between 27 and 28 mpg city and between 32 and 33 hwy if you don't lay into the turbo too often. Both still very respectable numbers for such an un-aerodynamic vehicle.

Does anyone know if there is a way to squeeze a larger gas tank under the xB? I would like to be able to carry more fuel (14 gallons would be great) on the xB to extend its range.

Definately not a fair comparison, DSM's are like the Goat's of the automobile world, they'll eat anything and everything, valves, pistons, differentials, oil, gas... they know no prejudice.

Oh, and I drive a turbo'ed xB. It still gets well over 20mpg with a heavy foot, and horribly rich tuning (don't worry, I'm working on that :P)

There appears to be enough room under the back but the trade off would be a big boom if someone rear-ends you. i.e. Ford Pinto :evil: ...not a lot of structure down there to protect a big tank. I read that the placement of the spare tire is factored into the crash design too.

How do you figure? That's if you don't do the proper maintenance on these cars. Mechanics that don't know what they are doing when it comes to DSM's, newbies that jump on the bandwagon after seeing F&F and buying a DSM will give you these results. I’ve owned my 1g DSM for 5 years and I drove that car hard. You need to know how these cars really work before you jump into them. It's not your average v-tec honda "tuner" out in the streets. If anything DSM's make an awesome platform. The 4g63 is a killa engine and handles excellent to boost and with the AWD platform just watch out. Just keep in mind any car running boost will need abit more attention then a car without it and more likely to run into more problems. As far as gas my GSX, it did good on gas and I had it running at 15psi everyday when the stock level was between 11-12 psi. If I could boost my XB I'd definitely do it in a heart beat. I miss the boost in my GSX already :(

"Goat's of the automobile world"?....not even close...far from it.


Just my 2 cents :P

yeah, I am pretty sure... because the typical supercharger or turbocharger will "steal" about 1mpg from your average... this is for typical driving and not hard core, on turbo driving...

my source is Corky Bell... he literally wrote the book on boosting...

I know the inside of a 4g63 like no body's business. Any DSM tuner will tell you there's always something to work on. They run like the best of them when they run, but don't stay that way. If driven easy, and not modded, a first gen will make it 150k+ without issues, but, if you drive like I do... you break stuff, constantly.

Ever build a 4g63 before? The last GSX I worked on, a 1990, we reworked with 1mm oversized valves, 5 angle valve job, bronze valve guides, 2g pistons, balance shaft removal mod, MAF mods, and a 6cm 16g. I broke more driveshafts with that thing than you can imagine.

They are DEFINATELY goats. They'll eat anything, like I said valves, pistons, differentials, oil, gas, driveshafts, domestics :P

I have definate love for the DSM, but I'm just stating the obvious.

I have been in contatc with Greddy aboutthis and they said the middle of 05 would be the earliest it is avail. to the market. They also won't provide any details about the kit ie... turbo size, intercooler option, cost, etc... I thought Greddy would hve one out fairly quick since they have one for the bB, i guess not though

I do see the scionspot.com has the greddy kit avaialble. So maybe Greddy is lying to me? or scionspot has the JDM bB kit, which is somewhat incompatable with the xB from what greddy told me. I'll grab the e-mails and post them with info from greddy

From Greddy:

Thanks for your interest in GReddy Products
Currently we only offer a turbo kit for the Japanese Spec Toyota BB.
It is
similar to the USA Spec Scion Xb, but the ECU and wiring are different.
We
have adapted our JDM kit to a USA spec car and we are working on
releasing a
revised kit for the USA market later, but currently we do not have a
release
date yet.
Please check back with our website www.greddy.com for updates or

authorized GReddy Dealer http://www.greddy.com

2nd e-mail

Sorry, but we do not have any information available for this kit at
this
moment. You will need to wait for a later time when we are sure we
will be
releasing a turbo kit for this application. Please keep in touch with
your
