2ZZ here i come

markiii · February 4, 2004, 15:00

I beleive it is 5/6 speed specific.

Lets keep it simple.

Roadster Clutch pedal
Roadster Shift Cage
Roadster Cables

Celica 2zz Engine
Celica 2zz ECU
Celica 6 speed box

Machined Celica Shaft or Same one from Roadtster 6 speed

I beleive the shaft from the 5 speed will fit the 2zz if you are staying with teh 5 speed box, but not if you convert to 6 speed.

CIN are you assuming the J-spec 6 speed Celica ratios are teh same as teh US? 0r are you using teh J-spec?

I think you could use the 6SMT gearbox but to tell you the truth I never saw an SMT box so I do not know if it even has the same shifter shaft.

Can you take a pic or 2 of the gearbox and near the linkages(under the airbox)?

The problem is that the gear ratios on the C60 gearbox(2ZZ gearbox) are closer together than the 1ZZ variants. It is much easier to keep the engine above 6000rpm with the C60 than with the 5speed or the 6 speed of the MR2.

Gear ratios of all the 2ZZ gearboxes are the same all over the world including the new Elise 111R gearbox.

The MR2/Celica 1ZZ gearboxes are also all the same but the japanese/US gearboxes have slightly shorter ratios than the UK ones.

In 6 speed form they just have the same ratios(US/JP the same as before, UK the same as before slightly longer) as the 5 speed but with an added 6th.

Yes the shafts are different because the 6 speed has reverse near 1st and 6th instead of R.

I am using the US gearbox but as I wrote in the other post, the ratios are the the same all over the world for the 2ZZ.

The machined shaft cost me about 10pounds to do but it was done by my uncle who works this stuff and did it for me. I think LR is selling them for $150. Remember that in the US labour is very expensive. I suggest you take out the celica one and machine it. Let me know when you are at that stage so I can try and send yo some pics of how it should become.

You can also try and use one from a MR2 6MT.

UK 1zz 6 speed boxes have a different final drive to the 5 speed so it's not justa case of having an extra gear.

as for 6speed SMT thats bringing us back to what started this whole issue, the 2zz ECU can't talk to teh SMT ECU. So if a 2zz is going in their it's going to have to be a manual box.

Yes it has a different final drive and different ratios than the equivalet 6speed in US/JP but IIRC it is the same final drive and ratios as the UK 5speed but with an additional 6th.

Still it is wider than the US/JP ones.

By comparison the 2ZZ gearbox has a more agressive final drive and closer ratios. So it is much better with the 2ZZ.

I would suggest you just get a 2ZZ gearbox and be done with it Adam.

As for the shaft. I dont have a shaft to work on anymore. What you do is you just take a 6speed shaft and go to the machine shop and tell him to make it longer and machine it like the 5 speed on the back end. The other end you just cut it out to fit.

I will try and find the pics LittleRocket had sent me of his conversion.

Anonymous · February 4, 2004, 15:56

BTW Adam. Do you have any more pics of the Roll bar you have? I am really courios about it. I like it a lot.

markiii · February 4, 2004, 16:00

its teh Netz if that helps.

Anonymous · February 4, 2004, 16:18

No not that one. The other one on the stripped car. The one that looks like the Techno Pro Spirit roll bar on their road car.

Jap GT300 · February 4, 2004, 16:30

Right, I have ordered the 2zz 6 speed and 2zz ECU both should be delivered tomorrow. I have also ordered the TRD shift cage which should be with me shortly.

I think I will order the other parts new from the dealership.

I do have some more pictures of the non-style Roll Bar which i'll post shortly in another thread.

Thanks:)

Oh and I dont know about buying from the dealer. I think the shaft will cost a lot and also the linkage. Try to find one from a yard or something.

Jap GT300 · February 6, 2004, 16:01

I now have all the parts excluding the rods (gearbox linkages)

I have just been reading up on SC and have realised another potential problem. How am I going to get the header to mate to the exhaust?

I think I am going to have to get one fabbed. I notice LR and 2XXY of SC are considering a rocket style header. Do you think Hayward and Scott would make a one off like this? I guess that will be big money.

Thanks Adam

markiii · February 6, 2004, 18:03

Adam,

I spoke to H&S regarding the header and they will make anything you want. To be honest though I would be tempted to speak to Paul at PPE and see if he will do you a rocket header with a 2zz flange. I'm sure he'll oblige. At the current exchange rate, and bearing in mind the design all ready exists, H&S would have to do R&D as well, it will probably be an all round better bet.

Jap GT300 · February 8, 2004, 11:40

I have got some preliminary pictures together. The gearbox and ECU are already connected to the engine. The end of the fuse box just seem to have been cut.

CIN, did you use most of the existing hoses etc. from the MR2. All of the 2zz stuff has been chopped in half.

It looks liek they could have been more sympathetic in removing the enigine. Shame they butchered teh wiring loom so badly, it would have easier to see if the engine runs before doing all the ballache of installing it.

1, Cin, did you use the 2zz or 1zz fuse box?
2, Cin, did you use teh MR2 driveshafts?

Inlet manifold probably should be replaced, though the current one should suffice to prove it runs.

Jap GT300 · February 8, 2004, 12:39

All components have a 60 day warranty. I also have 2 cerificates to say that it is a runner. 1 from japcarparts (UK and one from a company in Japan.

How many engine mounts should there be? I think I have found 3.

Also there is no throttle cable

And rather alarmingly something seem to have snapped. Do you know what it is?

Wiring is all 1ZZ. You need to add the VVTL-i wiris and the OCV wires and swap some pins.

The Driveshafts are MR-2

Engine mounts are 3 and 1 gearbox.

TCable is 1ZZ,

You seem to have the tensioner broken. I think you can use the 1ZZ istead of it. Se if it is the same.

That manifold should probably be replaced for max power.

Hoses you use 1ZZ and you have to close some of the ones on the 2ZZ head. You just swap everything from the 1ZZ to the 2ZZ inc wiring harness.

markiii · February 8, 2004, 13:05

Adam,

That look like the belt tensioner mount. Which is probably why your missing the serpentine belt.

The belt from teh 1zz will fit, the tensioner mount looks like it might as well. In which case we can unbolt it from the 1zz and swap

aaronjb · February 8, 2004, 13:15

Looking promising then Adam..

The damage looks like fairly typical breakers damage s:? :? s:? sadly.. Although it looks like one side of 'mount2' has been hacked off as well, or is that just a trick of the picture?

At this rate, you'll have it done by next weekend, no worries s;)

s;)

Jap GT300 · February 8, 2004, 13:43

Your right the belts and tensioner are both identical so that wont be a problem.

I want to get it done asap. don't know about next weekend though. hopefully 2-3 weeks.

Looks like i'm all set then. I'll start disconnectting all the stuff in my engine bay (preserving as much as possible).

What will need to be bled? PAS, Oil, coolant, anything else?

Also are the oil filters the same, as the 2zz is all dented, they look alike?

thanks adam

ps you're right one of the mounts has been cut s:x :x s:x

Anonymous · February 9, 2004, 20:58

Filters are the same. You will have to bleed the coolant and the clutch(which I found was a major PITA in my case because it was out of fluid and had major air in it).

Anonymous · February 9, 2004, 21:00

BTW I actually use a starlet filter which is the same as teh one on the 1zz-2zz. It is specified for the 3S-GE/3S-GTE.

Jap GT300 · February 10, 2004, 07:32

I'm finding that the Toyota range is very inter-changable. Just one last querie that has been bugging me and i've not been able to find an answer to. What engine mounts do i use.

Gearbox mount - 1ZZ
Intake mount - 1ZZ
Exhaust Mount - 2ZZ
Pulley Mount - 2ZZ

Is this right?

Thanks Adam
