Camshafts? - Page 2 - Toyota Yaris Forums

OIC! Could you post them, just for grins?

Nexus1155 · 07-01-2009, 08:20 PM

well both cams from gude and siphon car have different values for the duration but the lift is prob the same. This is the conundrum here, I am sure there is something to be had from this, but i mean its no American engine that you can gain like 50+ hp from cams, thats just not going to happen...

-1495 cubic centimeters
-75.0mm bore
-84.7mm (3.33-in) stroke
-dual overhead camshafts
(4 valves per cylinder via shimless bucket type tappets)
-valves inclined at 33.5°
-vane type VVT-i continuously variable intake valve timing device.
-valve diameters:
30.5 mm (1.20 in) for intake
25.5 mm (1.00 in) for exhast.
-cylinder block: aluminum with cast-in iron liners.
-cylinder and crankshaft centers are offset to reduce piston slapping.
-the NZ engine is placed transversely, canted rearward, with the intake side facing forward.
-the 1NZ-FE 1.5-L puts out 81 kW (110 hp) at 6000 rpm and 143 N•m (105 lb•ft) at 4200 rpm.

I believe these are the factory specs... anyone fee free to correct it. i had taken this from scionlife. I don't have duration or lift though... but i think mike (the guy who grinds cams) found them.

he feels he can grind a cam to make some good power for the 1nzfe... like i said i'll keep people updated...

Nexus1155 · 07-03-2009, 02:21 PM

Keep us updated TE! I would love to try to open up some new power on this car without FI. It currently has a 10.5:1 compression ratio. Bumping it up to 11.0:1 with decking and with the cams and some other minor mods we should have some good power out of this tiny little engine!

cali yaris · 07-03-2009, 03:04 PM

A more powerful N/A Yaris would be fun. I've considered doing an N/A motor with the stock one that just came out of my car. I already have the management in place, so it woudn't be too hard to do.

Nexus, what are you going to do to manage your motor?

Nexus1155 · 07-03-2009, 04:05 PM

Yeah I just hope the NA engine makes some good power too... I haven't thought about management yet, if anything i will either do an Emanage Blue for an easy way out, or if my buddy figures out the 1NZ ECU then I will flash it.

Its either this or nitrous so it can be deactivated so...

I think boosting in the winter will be really crappy with a FWD car so thats why I am opting for this instead..

turboecho2005 · 07-04-2009, 02:20 PM

I am still on him. He has this thread link. We can only hope he can make them for everyone. As soon as i know.. you guys will know.

cali yaris · 07-04-2009, 03:49 PM

I have two NOS kits for sale, FYI. In the classifieds section

suprf1y · 07-04-2009, 10:27 PM

OK guys, I'm the cam guy TE was talking about.
I have specialized in Suzuki, and to a lesser extent, Isuzu cams for the last 6, or 7 years, and will grind just about anything, as long as I am comfortable that what I am doing will provide with you are looking for.
The difference between me, and most custom grinders is that I have been building motors for over 30 years. I have a pretty good handle on what most motors want for different applications, and I take the time to find out how each profile will work in each situation. I almost always insist on degreeing the stock cams in the intended cylinder head. Once I am familiar with the valvetrain, and geometry, I will start working on a profile. To give you an idea why this matters, in one of the Suzuki motors, grind the intake lobe, and the rocker ratio quickly jumps up .2 points. Grind the exhaust lobe, and you lose .1 point. I have customers with these motors that have had cams ground by major custom shops that just don't work. About 16 hours of development, and I have profiles for that motor that range from mild, to wild, and they work.

If you are interested in cams I will work with you, but understand that I am not familiar with the valvetrain in the motors, so you guys will have to work with me. I will need a head, a set of cams, and timing sprockets to do some degreeing. I will not charge for development, and I will not sell you something that I believe will not work.

And for the record, TE, there is no worse cam for a turbo, or SC application than the stock cams. Its all about airflow. You turbo to make power, yet you run the stock restrictive, low lift, (very) short duration cams. You cam for your intended powerband, and RPM range, regardless of turbo, or not.
You're familiar with the factory turbo cars. On mine, with stock cam, I was running 25 psi boost. Once I put in a mild performance cam, all I could make, with wastegate disconnected, was 15 psi. Why? The motor was now flowing so much air (and making so much power), the little turbo could not flow enough to build the higher pressure. More airflow, more power, at less pressure (heat). Its all good

turboecho2005 · 07-05-2009, 01:51 AM

Thanks for joining mike!

I look forward to seeing what you can make for these motors. You know more abouts cams then i do!

Lets see if someone on this forum wants to get some cams made :) Garm?

Parmas · 07-05-2009, 09:55 AM

Seems a good idea although that depends the cost of the work done. Also I think one might need an upgraded engine management since the stock ecu can't handle the modified cams.

Interesting info there mike!

suprf1y · 07-05-2009, 11:03 AM

The two biggest concerns are always, the price, and will it work with the fuel management?

The price would be under $300 per pair, and my goal ultimately, would be to develop something that would work with your stock ECU. Most people are looking for a little more performance, but few have the resources to buy, install, and tune an aftermarket fuel management system.
The Suzuki application I mentioned, with the goofy rocker arm ratios, is OBD II, and the grinds that I developed work fine with the stock ECU.

My estimate, is that the stock cams have low lift, in the .300 range, and duration (at .050") in the 180 range. These are very conservative numbers, but leave considerable room for improvement.

So what I need to know is, where else was the motor used? Will it be possible to get cores from an earlier application (these cars are too new to find in the yards, or core suppliers)? Does anybody have an interest in sending me a head, with cams to do the development?

BTW, I do offer cylinder head packages which include rebuild, porting, decking (machine for compression) O ringing, if required, and cams. I stock 1 pc polished SS valves for the Suzukis, in stock and oversizes.
I will see if I can source the same for the Yaris motor.

eTiMaGo · 07-05-2009, 11:36 AM

In Canada, you ought to be able to get your hands on the old Echo, it's been there for years and uses the 1NZ-FE too

turboecho2005 · 07-05-2009, 11:44 AM

They started production in 1999 so our motors are 10 years old. Someone must have a spare head kicking around to let mike do some R&D

Nexus1155 · 07-05-2009, 01:41 PM

I know someone who has one, but it might be bare, so i'll check!

Tamago · 07-05-2009, 06:55 PM

yes, it's bare

Parmas · 07-05-2009, 07:42 PM

I have a complete 2NZFE that was previously in car. Most components match the 1NZFE and all cyclinder head + components are alike. Although I might be interested, I live in europe and it will be costly to ship it to CA.

suprf1y · 07-05-2009, 09:41 PM

OK, so it looks like its a bucket style lifter, no rocker.
Hydraulic, or solid lifters?
