I got some word back today about cams for the xB/xA. Unfortuantely there will not be any production cams. You can though send your cams to Crower, and for $95 per cam they will regrind them for you:

No new cores for that engine and no plans at this time.

Regrinds on your stock cams are available. Specs are typically 10-15 degrees
more duration and .010"-.015" more lift. HP gains are in the 5-15 range
depending on tuning. Rough idle is common if we exceed the above figures.

Cost is $95 per cam. Allow 1 week shop time + shipping. Send cores along
with detailed note stating engine model, intended application, power adders
(turbo, NOS, etc), rpm range to address below.

I have an extra 1nz that i will be taking the cams out and sending them to crower for the regrind. I'll let you know how it goes.

ohhh 5-15 hp? NICE .Do they have any dyno sheets to back those claims?

ohhh 5-15 hp? NICE .Do they have any dyno sheets to back those claims?

Considering no one has prob. sent their cams off to them for this application, i'm sure they don't. If you want a dyno it is up to the end user to dyno not the company. They are simply making statements from experience. Once i get the cams out of my extra engine i will send them out and have them regournd for a Supercharged application. Toyota wants 216 for the intake cam and 227 for the exhaust cam.

We'll see how it goes, for 95 bucks a cam though, it is a good deal especially if they are willing to grind them for a trubo/sc applications

very nice deal

better than a 4k stroker kit

What would be a good cam profile for a FI application? I wonder how much they would charge to re-grind some 1zz cams.

Who has a stroker kit out for 4K? I am kinda interested in something like that...

Call or e-mail them. They may already make cams for the 1zz.

If they don't send your cams and tell them what application you want them for. They will then regrind them with the correct profile.

good lookin out...
let me know how it works out.... :pray:

will keep everyone updated

man i asked this a while back and i got no answer. i even made a thread on it. oh well

good find!

maybe this should be a sticky until camshafts become widely available

One can always go to the local Pick-N-Pull and get some used camshaft out of a wrecked Scion. I used to do that all of the time back in 1982-4 when I was experimenting w/ 20RCs. Good price on the grinds too!

then we would have to sticky all parts threads, they might not be widely avail....

we will just need to keep this up on top how ever we can....

i wonder if the cams in the used echo motor i picked up have a diff profile than the scion....
i know its the same engine code, but there could be changes to the cams....

My sentiments exactly . Anyone got the specs from both so we can figure this out?

i wonder if the cams in the used echo motor i picked up have a diff profile than the scion....
i know its the same engine code, but there could be changes to the cams....

Hmmmmm good thinking. I'll see if i can dig up some spec. sheets. Most manufacturers don't list cam duartion and lift though. We'll see what we can get.

.......style versus substance should never race each other..... or a WRX!

being that they have the same output, I highly doubt it.

they could have diff profiles and produce the same power.
i am just wondering in case i send in some echo cams and say add 10 degrees duration when the scions already have the 10 degrees added. so i would have just spent 190 bucks to make scion cams that i already have....

i am not expecting them to be diff, just want to know for sure.

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?

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

That is why i am getting custom camshafts done :lalala:

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 :bow:

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.

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.

I have an echo motor as well. 2003 with 10k miles. Stripped it bare and i am now building it, with the listed components. We'll see how it turns out

I have a lead on a few Echo motors. Just wondering if the valve sizes, cam durations, and internals were the same/interchangable. I'm also tempted in stripping one down, and rebuilding it to see what I can get out of it.

Also, how would the ECU and re-ground cams work? Think they would be compatible?

The last time I worked on engines this in-depth(20+years ago), I didn't have to worry about ECUs or FI, just smog pumps and beaucoup vacumn lines.

i'd pick up a motor...the parts are very interchangable...they should all have the same specs (valves, cams, pistons....)

the ecu will be ok, but you should use a piggyback to help tune it better....

The problem w/ the ECU is, its a closed loop. Some of the Subys have closed loop ECUs and resest back to factory specs after a few miles.

thats what the piggy back is used for...it will intercept the signals and modify them...

Try resetting the ECU. I did that and it cauased the car to run diffrently for some time. Then as stated it learned itself and set it back to what it was before. As you know the Suby's, if you flash the ECU you can actually get an extar 10-15 horse at the wheels. We'll see how the cam regrinds go

Yeah, that's why it isn't recommended to run the SAFC-II.

I have a good friend that has taken the EF-101s courses, and he said hooking the SAFC-II into the xB ruins the engine';s performance, a wreaks havoc on the ECU.

He's checking into a few options for us also.

resetting the ECU only holds for a little bit....it is a learning ECU...right...
it will try to correct its self over time

would love to hear what he diggs up...

Call up toyota and get the PART NUMBERS for the cams in each vehicle...

The engines are identical. Period. You're not going to make identical power with 2 different cam profiles!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! You're also not going to advance timing at ALL on 87 octane fuel w/ such high compression. It's already pushed pretty close to its limits as far as knock goes...

THINK ABOUT IT!

regrinding a cam for an overhead cam motor is not the same as for a push rod motor. with push rods you just get longer ones to make up for the material that is ground off the flat side of the cam. (side opposite the lobe) that makes the lifter ride lower in its bore so you need longer rods to mantain geometry. on over head cams there is a follower that rides on the cam. these are hydraulic just like hydraulic lifters in the push rod motors. they can not compensate for the removed material so they will require shimming. if these motors are solid "lifter" then it would be even more important. some over head cam motors use the top of the valve as followers. if thats the case you would need new valves. longer to make up the diff. crower comp lunati isky hayes will all regrind cams for you to what ever you want. they don't care. if you want to regrind your cams be carefull and pay close attention to all the effected components.

all electronic feul injected cars run in closed loop. they also run in open loop. open loop is preset timing feul etc. it is used for startup and warm up. kinda like a choke system. closed loop is when the engine uses it sensors O2 MAF MAP etc and optimizes feul spark etc. closed loop is what you want for performance gas milage and good drivability. open loop is is not efficiant and is used to get the cats and O2 sensors hot. when you make changes like cams you need to address the open loop settings as well. your piggy back systems won't help open loop. PCM ECU EMU what ever you call your engine management system needs to be calibrated "flashed"

hot rodding is where its at
watch out for all the nickles and dimes those are what hurts.

good luck L8R

Whatever became of this? Did anybody find out the cam durations? Did cams get made? Did they help?

this should be bumped.

there are crower cams for the 1.8L 1ZZ-FE so that would mean CAMS do work we just need some made for the 1NZ-FE

there are also cams available for the 2ZZ-FE !

you can work out the cam duration if you download a copy of the service manual for a yaris or echo of one of the other sites http://www.yarisworld.com/forums/showthread.php?t=47

scroll to post #5 download the engine.zip file i worked it out at something like
Intake 225 duration
Echaust 224 duration

but i dont know if i worked it out correctly

I NEED INFORMATION ABOUT CROWE CAMS. If anybody had installed them and what were the results. I have interest in buying one for my toyota Echo HB 2NZFE

BUMP to keep this on top until the cams are in...

This post is now 16 months old with no new posted results. I think it is safe to say that nothing happened with it. and Crower also does not state any camshafts except for the Supra and the Turono.
