2zz Swap on Vitz/Yaris SCP90

[blindmanwatching]

Hi Everyone,

My first post on this forum. I've got 2zz swap done on my 1.0L 1KR JDM Vitz. The setup:

1) 2zz from a 2001 Celica with C60 6-speed manual.

2)A/T ECU since I couldnt find a MT ECU so currently using a A/T ECU with this manual setup.

3) 2.5" Shortram intake which is housing the MAF sensor.

3) 2.25" Free flow exhaust.

4) Bigger radiator with two fans.(not sure of the size)


So far there have been numerous issue which we are trying to solve. I'm going to mention them so if anyone can help out please do:

1)Top of shock absorber hats are popping out more than they previously did with the stock engine. Stock shocks with Tanabe lowering springs.

2) The car is running a bit rich(it pops out a flame between gear shifts). I've confused as to what the problem might be. Any suggestions?

3) Engine shows 3 error codes are related to the transmission(since we are using manual on an auto ECU). Can anyone tell if this has an adverse effect on the ECU perfromance??

4) Seems like the car loses traction from the left wheel and goes into a wheel spin. Right wheel holds the road better :iono: There is also torque steer towards the left.

5) The stock AC is going to be used with this setup. Anyone know if it will cause any compatibility issue with the different ECU??

6) I'm using the stock fuel pump. Does that need to be upgraded?





0-100 in. Car hits 100km/h when you hear the second gear lock up:

0-100 run with two people in the car, slight wheel spin and sligh uphill drive. Still did 7-8sec

More pictures in the following thread :D

[Alexrahl]

You got any pictures? I would definitely replace the fuel pump with a high output unit.

[LTHatch]

Can't wait to see pictures and video of this!
1:Same thing with my Yaris when i installed Eibachs springs with stock shocks, been driving for almost a year no issues. I believe it is normal.
2: Same bit here, especially after deleting the muffler. High load+rich tune from Toyota+straight through system/muffler= POP. It has been doing it ever since the muffler delete.
4: No LSD most likely, did the Celicas come with LSD standard?
6: I would just for the future, gives you all the flexibility for far more power down the road if you wish.

1)Top of shock absorber hats are popping out more than they previously did with the stock engine. Stock shocks with Tanabe lowering springs. {This is normal, I'd recommend getting coilovers if within budget}

2) The car is running a bit rich(it pops out a flame between gear shifts). I've confused as to what the problem might be. Any suggestions? {This is normal with a free flowing exhaust}

3) Engine shows 3 error codes are related to the transmission(since we are using manual on an auto ECU). Can anyone tell if this has an adverse effect on the ECU perfromance?? {It shouldn't affect performance, I've been using my A/T ECU since completing my manual swap in April, the car runs great}

4) Seems like the car loses traction from the left wheel and goes into a wheel spin. Right wheel holds the road better There is also torque steer towards the left. {This is normal, a LSD will cure this}

5) The stock AC is going to be used with this setup. Anyone know if it will cause any compatibility issue with the different ECU?? {Not sure about this, though it shouldn't}

6) I'm using the stock fuel pump. Does that need to be upgraded? {Definitely needs to be upgraded if the the stock yaris pump}


I'm really jealous that you got to pull off this swap but happy at the same time. A lot of people have talked about it but no one ever went through with it.

I'm a regular over Newcelica.org. as "many".
Ive been building these engines for a while and know their potential and their problems.

Nice swap but why are you using the auto ecu...of course your going to have problems...it's meant to be used with an auto 4 speed and it's gearing. You might not even be hitting Lift(second cam) and having the auto ecu I bet your not even getting higher then 7900 rpm.before it's pulling timing and fuel. Get the proper ecu for that engine combo....or get a power fc which is a very descent standalone for the 2ZZ.

2.25 isn't enough for a high revving 1.8 ltrs. get a minimum of 2.5" exhaust.

The Transmission doesn't come with LSD in any configuration (C56, C60 , C64 e.t.c). There's a couple of good one out there that will do the trick. Monkeywrench has a couple available. The left wheel has less weight on it making it easier to go into a wheels spin. Your torque steer is exactly whats happening to the right wheel that is doing all of the pulling, effectively pulling you to your left.

The only concern of using the stock AC is the pulley size. The 2ZZ can rev safely to 8400rpm (stock valves and springs) so that small pulley is going to be over spinning from it's intended use.

Your next mod should be a wide band.

[Bluevitz-rs]

I'm interested to see what mods you had to do to the frame of the car to get it to fit.

[blindmanwatching]

Thanks everyone for the help and suggestions. Here are the pics I have taken so far and the first run video. Note that this is still a work in progress :smile:

If anyone has any questions regarding the swap i'll be happy to help.

Very useful info. I'm using the the A/T ECU because I couldnt find a MT ECU in my country, so have to make do. Can you suggest a fc for the 2zz?

Are you sure about the exhaust size. Note that its a 2.25" with no restrictions at all. Just a straight pipe with a free flowing muffler at the end.


@Everyone

I've posted the first set of pics just waiting for the admin review.

Thanks :smile:

Adaptronic makes a great fuel controller for the 2ZZ. I just finished tuning a client's 2ZZ Lotus Elise and with a T28 turbo and the Adaptronic stand-alone ECU we were able to get 319 HP / 239 ft-lbs torque out of the 2ZZ on 93 octane gas.

[blindmanwatching]

been almost 24hrs since i posted the pictures which were supposed to be moderated by the admin? Admin help?

[Bluevitz-rs]

Admins are often MIA unfortunately. Did you just try to post them as attachments or IMG links from an picture hosting site like photobucket?

:bow:

[CTScott]

As Bluevitz-RS asked, did you have to do any modifications of the front frame rails to fit the engine in there with the 6 speed tranny?

By the way, It looks great. That engine is so awesome when you get the lift cam doing its thing properly.

[Betrivent]

Holy moly I really need videos NAO!

[ilikerice]

I have so many questions on this swap.

What mounts did you fabricate? The 2zz mounts or the 2nz mounts?

You said you changed from manual to auto trans. What shift linkage did you use and how are they rounted?

Wire harness... Did you modify the Yaris engine harness, or use entire celica engine and cabin harness. what and where were you splicing (i.e. at the ecu or the engine bay)

also, to support the CAN system for A/C controls, are you still using the Yaris ecu?

now, you say its a Vitz 1.0.. Did that have the electric power steering or the pump? also, was that drive by wire throttle cable or drive by cable on the original 2nz motor? If I had to assume, it was drive by cable and power steering pump. But just wanted to be sure

Mounts: The timing belt and rear mount are the same as for the 1kr engine( I had a 1kr not a 2nz). We had to attached a modified plate to the timing belt mount, since the bolts on the original mount did not align with those on the 2zz( as you can see in the picture. The original mount has a smaller aluminum plate which bolts onto the 1kr engine)

http://i1374.photobucket.com/albums/ag433/Nusabbeh_Waqar/IMAG0342_zpsc06fd813.jpg (http://s1374.photobucket.com/user/Nusabbeh_Waqar/media/IMAG0342_zpsc06fd813.jpg.html)

The rear mount remained unmodified. But we had to make a custom bracket on the engine which would fit that mount perfectly.

A new front mount had to be installed in the front, under the radiator. It was done by installing a reinforcement beam on the original beam and then welding the mount on top of it. This modification is totally bolt on( the whole reinforcement beam bolts on to the structure of the car, no damage done.)

The transmisson mount fits in the same place as the 1kr but its an all together different mount with a custom made bracket which bolts on to the transmission. transmission. Im not sure which car that mount is from, probably an old corolla or a civic.

Gear Linkage: The gear cables came with my 6speed transmission. We only had to install a manual shifter and connect the cable and after some adjustment it works very well. let me know if you need something more precise

Wireharness: For the engine we used the original celica harness and for the cabine we used the original Vitz harness. Im not sure of whether the cabin harness had to be spliced or not ...sorry

My vitz had an EPS and an electronic throttle. So we took the power steering pump off the 2zz and adjusted the fan belt accordingly. Im using the original EPS.

For the throttle we had to make a hole for the throttle cable and fix a mechanical throttle. thats it.

The AC still hasnt been fitted yet. So cant say anything.

Ok for some reason the pictures did not attach. Kindly visit my photobucket to view the pictures, regarding mounts. Important things to notice have been highlighted.


Hope all this helps :smile:

I've made the post regarding the mounts. Waiting for admin approval. But yes the front frame had to be modified a bit. The tranny didnt fit in, so we had to hammer bend the frame right above the transmission area to make an inch of room for the bigger transmission.

[Bluevitz-rs]

What about on the pulley side. Did you have to mod the frame there?

[alias06]

"You said you changed from manual to auto trans. What shift linkage did you use and how are they rounted?"



He didn't say that he switched from a manual to an auto transmission, instead he stated that he is using an auto trans ECU with the manual c60 trans...

[ilikerice]

Ok, question still stands.. which shift linkage did he use. Yaris or celica?

[blindmanwatching]

I made a detailed post regarding the mounts a week ago. Admin still hasnt approved of it :iono: ADMIN HELP!!!

I'll make sure and let you know, But as far as I know we used the cable and shifter from a Corolla.

Guys I need help with installing an OBD2 port. How do i install it to the new ECU? Anyone know how it is wired?

Did you get your hands on the wiring diagrams for the car that you grabbed the ECM from?

There are numurous wiring diagrams available online, for the 2001 celica, but I cant understand the whole concept of how the ECM is wired to the OBD2 plug. Need help with that.

[blindmanwatching]

Updates:

Got the cooling system sorted out. Initially there was no thermostat installed and the temperature sensor was not plugged to keep the fans running at all times. Now 82C thermostat has been installed and temperature sensor has been plugged back on. As a result the LIFT is working perfectly now :thumbup: and the car accelerates like crazy when LIFT hits.(Video coming soon)

AC condenser has also been installed. But having problem with the AC compressor. The 1KR compressor which was fitted on this 2zz has cracked :iono:. probably the reason being the smaller pulley size. And i cant install the original compressor because there is no room for a larger pulley. Someone advise?

Wiring to the OBD plug is typically very trivial. That vintage is ISO9141, so there is one (K line) wire that is the communications wire.

Pin 16 is constant 12 V power
Pin 4 and 5 are grounds
Pin 7 is SIL, which is a direct connection to the ECM
Pin 13 is TC, which is a direct connection to the ECM

An OBDII reader communicates with the ECM via pin 7, which is the "K Line". For a standard OBD reader, just 4,5,7 and 16 are needed. Pin 13 is a toyota specific diagnostic wire.

Thanks for the response.but on the ECM end, where will all these wires be connected? or will only pin 7 be connected to one of the pins on the ECM?

[CTScott]

7 and 13 are the only ones that connect directly to the ECM.

[blindmanwatching]

7 and 13 are the only ones that connect directly to the ECM.

Ok. And are there any connections to the different sensors of the car...or does pin 7 and 13 provide all the data from the ECM to OBD2?

[CTScott]

With ODBII the diagnostic tool just talks to the ECM and the ECM does all of the talking to the sensors.
