Scion won't release any information on their cams as far as Duration and Lift. I used the live Scion chat today and they said they are not allowed to release the stock duration and lift spec.s for their cams.

They alos said there is technical specs. document available, but he didn't know the name or anything.

I asked about the crank pulley since soe have said metal, and some have said plastic. He was also unable to confirm whether it was metal or plastic. So all in all today Scion was pretty much no help at all, thanks again Scion.

 

my crank pulley was metal....
i have the service manuals for the xb, maybe the cam info is in there...
but i still won't know about the echo's cam...

 

I'm assuming Toyota was going with cost effectivity here and just plopped it into the Scion with no major mods to it. Why would they re-design the camshaft between the 2 cars? It just doesn't seem like the toyota thing to do.

 

The motors aren't the exact same just so everyone knows.

 

What is diffrent between the 1nz-fe from and echo and the 1nz-fe from a xa/xb?

because if i look up the specs. on the Echo it has the exact same specs. as the xb/xa, to include CR, bore, stroke, etc.... They both put the same HP out at the same RPM as well as Tq. I woudl like to know what the diffrences are between the 2?

 

There is no difference. It is the same motor. The Tranny has different gear ratios though.

 

so then the cam profile etc.....shoudl all be the same. If the only diffrence being the tranny that is a very small diffrence. Although i don't know why they would regear the trannies......the cars both weigh relatively the same, and they both get realtively same MPG.

Tranny Specs:

Toyota Echo 1nz-fe tranny

Manual five-speed transmission with shift lever on floor,
3.545:1 first gear ratio,
1.904:1 second gear ratio,
1.31:1 third gear ratio,
0.969:1 fourth gear ratio,
0.815:1 fifth gear ratio and
3.25:1 reverse gear ratio
Final Drive 3.722:1


Scion Xb 1nz-fe tranny

Manual five-speed transmission with shift lever on floor,
3.545:1 first gear ratio,
1.904:1 second gear ratio,
1.31:1 third gear ratio,
0.969:1 fourth gear ratio,
0.815:1 fifth gear ratio and
3.25:1 reverse gear ratio
Final Drive 4.31:1

**These numbers pulled from http://www.lacarguy.com ******************

Looks like the only diffrence is our xB has a larger Final Drive. I wander why Toyota was so compelled to put a larger FD on the box than on the echo?

 

the final drive gears were made to give us more performance....

the echos gears are for fuel mileage

 

Perfect for a turbo application

 

That is why i am getting custom camshafts done

My setup is looking like so:

1nz-fe block
Block:
custom block guard
custom 9.0:1 CP Pistons
Custom CP Rods/rings/connector pins
Fully Blue Print and Balance the block

Head:
Crower custom grind cams for turbo application
trying to locate someone who can do custom vales,springs,retainers maybe Super Tech?
Port and Polish

Turbo:
Custome equal length manifold, welded by me
Turbo is undecided right now I am thinking T3/T04E just for cost effectiveness, possibly a 14 B though
2.5" Piping all the way
Precision 600hp Intercooler
3" down pipe, custom 3" exhaust to a magnaflow muffler or something
Wastegate pending Turbo decision....internal or external external WG will be TIAL though.

That is what we got going right now. Goal is for 250-300 at the wheels. I know it seems like a long shot, but i thoroughly believe this engine can handle it.

 

You're gonna have a hell of a time trying to fit a T3/T04E in there. The biggest I think you could squeeze back there will be a T28.

 

hmmm you can try indy cylinder head

sure they do mostly mopar sb and bb set up's. if you have the money i'm sure they can do you work and do a great job at it...

 

I have this taken care of.. Essentially what i will try to do with the manifold is to create a "sidewinder" manifold to bring the turbo out away from the firewall and give us more space.









Mine of course will be minus the huge 4 inch Down pipe But you get the idea right?[/img]

 

Very nice

 

I will be welding something like that, except for the Scion. Those are all Love Fab manfolds. I am looking to bring the turbo out to the driver side, where we will have room for a T3/T04E

AS fabrication continues we'll see what happens. I may abandon this idea and just stick a 14b or T28 back there. IT is really up in the air right now. I am getting my design plans ready though

 

All I know is from a guy who took apart both a xB and an echo motor somethings diff , maybe I'm wrong , I may be helpful but I can't always be right , I try. sorry If I misled anyone

 

I have a Echo motor that I'm about to put into my XB with internal mods of course. There are no cosmetic differences that I can see, and I've had the engine almost 7 months, and stripped it bare. I don't see anything differnt at all.

 

or supercharger....

whats that i keep tripping over in the shop....

 

i have not fully ripped the echo motor down yet....but like munch says, cosmetic wise i don't see a difference...
but that does not mean some things could be slightly different....
i did not get to compare cams next to each other....meh

 

What i was told was cams, and something about the internals being made of different materials and a few minor measurements changed , for performance? I dont know. for longevity? i dont know . I only have so much real world first hand with these motors ,i have a vast general knowledge on 99% of automotive things. I am slowly learning all there is to learn about these lil 1.5's . I wish I had a spare motor around to tool on and check and see how hard/easy certain things are on these motors in comparison with nissan/honda and other toyota motors.
