i tried searching forums and found no info. does anyone know if this porduct is even made? or could i throw in a celica gts 6 speed in there?

 

unless the ratio is really short, like rally race type short gearing...its pointless to have a six speed in a 1.5l. Why do you want a six speed for a 1nz?

To answer your question, no direct bolt ons and no one makes a six speed for the 1nz. go custom if you really want it.

well short ratio for obvious reasons and that 6th gear so i'm not doing 4k rpms on the highway. keep in mind i'm a noob bastard so if i'm really just wasting my time let me know. your help is much appreciated.

 

Technically, you are wasting your time with this question being no one makes a tranny like that for the 1nz. It has been discussed before on scionlife, but its been a while which is probably why you couldn't find anything.

For the six speed to work, 1st gear would be pretty pointless. 1st gear would have to be really, really close ratio and 2-5th would also have to be extremely close. Also, sixth gear couldn't drop too much because the reason why our gears are spaced close is to get the most power out of them. You are driving highway speeds at a fairly high rpm so you can pass others without shifting into 2nd or taking OD off (auto), or down shifting into 4th. (manual)

Theres logic behind our trannys and why they are geared the way it is. A six speed would be fun if it was really close because, i love reving it high and close ratios. But, to be honest, its pointless for us.

Yes,this is quite true. Want to know why?

Go drive your car around in 5th gear at 2300 rpm. Mash the gas. Go anywhere fast?

Try it again at 3500 RPM. Probably a bit better.

Want to know how to get the best highway gas mileage? Don't go over 60 or 65. Trust me, with all the methods I use for driving, I get a consistent 40 mpg.

 

you'll get used to the high rpm's in givin time

 

^ ^

Exactly. I'm used to, even prior before owning a scion. (i built a heavily modded tegra, and it was pretty high on freeway as well)

So just give it time. If you were cruising at 2,500rpm going 60-70. You would have to downshift constantly to go anywhere.

I had a racing computer on my 90' fwd turbo laser and it was fun driving that, cause the rpm's was unlimted, i was going over 8000 rpm with no damage on my car. That computer was made for racing only!

 

sorry bro. pipe dreams.

and wreck you racing computer may have let the fuel and spark keep going past 8k but wait till the valvetrain....... or oil foaming/thining.,

 

I would love to see Scion come out with a 6 speed just to up the MPG! If I want to pass someone I'll settle for down shifting. My 2000 Echo had the same engine but taller gears and constantly got 10mpg better than my XA. Besides I hate the whine when I'm driving 70. I too tried to keep the speed below 60 to up the mpg.....it didn't work.

 

Even put aside the downshifting to pass someone. Think of it this way. Most six speed cars have either a high redline, or a good amount of power..most of the time both.

For the six speed to even be useful, it would have to be a close ratio. In order for the six speed to work, sixth couldn't drop too low going just say 70. If it did, not only would you not have enough power to keep the speed of 70, but you would also have the motor struggle to stay in 6th because of the lack of power. Below 4,200rpm, we are powerless. Which is fine for around town driving, but at 70mph we would need probably 80whp to keep at that speed, almost flooring it. It would be very stressful on the motor, and that 80whp is probably somewhere around 2,800rpm. Which would drop the rpm range a good deal for manual owners, but you would have to really keep the pedal down just to keep at that speed. Not to mention, going up hills you would constantly downshift for every hill. It wouldn't be practical enough for toyota to even consider it. Most manual owners love to shift, but thats a little ridiculous. Most would end up just keeping it in 5th, and using 6th on a track to top out..thats about it.

Hopefully that makes sense, im tired so my train of thought is off and on.

EDIT: Another thing i forgot to mention. Due to flooring it in sixth to keep at say 70mph, you would loose mpg as a result of it.

OK, lets see, a 6 speed would work, and very easily i might add, all you do is add another gear to our existing 5 speed, this would in fact allow the engive to rev a lil lower and freeway speeds, after all thats what 6th gear woudl really be for anyways. This would also allow us to keep the first 5 gears so we could sill have the closed ration to really get the car moving. None of this closed ration 6 speed, not worth it, you cont do it stuff really applies. If i made trannies, i would just add another gear and be on my merry way.

 

all i know is after some power adders i can drive up to tahoe in 5th gear teh whole way while my other scion bretheren had to downshift to 4th. all the while i was in 5th and PASSING them...

 

Its not as simple as just adding another gear. If the revs dropped too low, you wouldn't have enough power to keep at a given highway speed.

 

what you can do (what I WILL do in the future) is drop a celica gts engine and trany and give my hatch a little more *********. You will need to do some real custom work, but if you really want it...

 

Any motor swap can be done. I downloaded a video not too long ago of a geo metro running 10's on the 1/4. How? RWD, 3.something small v8 turbocharged. Dropped the motor in the back seat. If you really wanted it, you could probably drop a v10 in the back with enough time, money, and effort. But would it be worth it? I say no, i would rather get the most whp i can, but still being able to drive it daily. Your motor swap idea would allow that, providing insurance or cops don't find out. Illegally legal in otherwords.

Personally, a dream motor for the xb for myself would be a 3rotor. But its not worth it to me, plus, no $$$ to do something that drastic. However, a six speed with a 1nz is not logical nor would it ever work without it being pointless to have that extra gear.

It has five gears, and geared high for many logical reasons. Yeah, our MPG hurts. But honestly, who cares. The car wasn't designed for highway driving, otherwise we would have a different motor. We are designed for the city environment. We can be quick in the 1/4, we can definitely be fast in autocross. But by no means are we designed to cruise 80mph and get 30+ mpg. No car is designed like that really. The faster you go, the more fuel is needed. That extra gear would equal more pressure on the gas pressure to keep a constant speed which as a result, more fuel would be needed to keep at that speed. Which of course, equals even worse MPG. Counter effect. If you wanted fantastic MPG you bought the wrong car. Our gas tanks are small, 300 miles i've heard people complain about. But 300 miles is 30ishMPG and thats good compared to many other cars out there.

Wny not change 5th to a higher gear (lower number) and the final drive gear to a higher gear (lower n mber). This way, you have more of an overdrive with the 5th and R&P, plus your other gears will be close to the same.
And KillerxRomances...I just read an atricle (actually a couple) staing it only takes 18 HP to maintain 60 MPH in a CRX. So to say we need 80 HP to keep an xB at 70 is off base. I know you just probably threw that number out there, but it takes A LOT LESS HP to maintain than you would think.
Also, lets say you used ALL the fuel to get to that 300 miles per tank, thats more like 25 MPG not 30.

 

How do you get 25? Our tank isn't that much bigger than 10gal? But i said 30ish, i wasn't being exact. I did just throw a number out there, but we need more than 18whp to keep at 60. The CRX is 2200lbs with a driver (i believe, could be wrong by a hundred or so), we are 2,600lbs give or take with a driver. So, we are obviously going to need more whp to keep at that speed. Maybe not as high as 80whp, but definitely more than 18. Not to mention areodynamics are better on a crx which allows it to keep at that speed without much whp. Not saying you are wrong, so don't get that impression! But i am saying the CRX doesn't need as much power to keep at any given speed compared to us. Like, keeping at 75mph at 2,200rpm (just an example) would seem like it would basically be like trying to claim a hill in 4th gear at 40mph. You would have to downshift to keep the motor and tranny running steady and safely. Especially if you wanted to pass someone. Just my opinion, it doesn't seem like it would work at all. I could be very wrong, and it could be possible. But from my experience, it doesn't seem possible. *shrug*

How did I get 25? I divided 11.9 gal. into 300 miles. Those ARE the figures you used, right? 25.21 MPG. And you are right, the xB would need a little more power to keep a steady 70 MPH, but I was just saying it ISN'T anywhere near the 80 HP you threw out there. The Prius only needs 15 HP to hold steady at 60 MPH, but that is in theory AND a perfectly flat road, which will almost never happen.
Anyway, to get back on topic, instead of trying to fit a 6-speed into an xA, why not research different transmission gears and final drive gears...it MAY be cheaper, easier, AND MORE POSSIBLE.

 

I just rounded 10gal tank to get an estimate, for some reason i thought our tank was smaller than that. *shrug* You sounded a little upset? If so, take it easy, i wasn't trying to make you upset.

Insead of looking into gearing, how about you just get used to driving at a higher rpm? (not you, just you as in whoever wants a six speed) Thats just my opinion, good luck to anyone who does the six speed or different gear options!!
