Where is the vacuum pump in a Starlet Glanza/GT?

[Frankieflowers]

Hey guys. I can’t figure oit where the rear intake manifold vacuum pipes should go. In the Corolla 4efe they go to the steering pump. Where do they go in the Starlet? This system pull up the idle rpm when moving the steering wheel.

Let me know what you think.

Corolla

Starlet

Those lines head down to the steering rack on a Starlet.

So it means that the steering rack has vacuum line in and out. The Corolla doesn’t have it. It would be nice to see a picture where it is to possibly modify it in the future.
otherwise, I would have to create a metal relocation bracket to fit the Corolla pump.

Do you think I could modify the Corolla steering raxk and put in the valve?

Will be hunting through steering stuff at the weekend so I'll grab a pic of a Starlet rack.

Haven't any experience with the Corollas but you can see the same thing in that first diagram (labelled 17630).

Looks like the 4EFTE takes all it's vacuum feeds from the vacuum block (the bent metal pipe under the inlet manifold labelled 17303 no1) so you should be able to delete the Corolla vacuum pump?

The purpose of this job was to reactivate the vacuum line that raises RPM when moving the steering wheel. Both FE and FTE, inlet manifold, have the vacuum lines coming out to feed this purpose. The difference is that as you said, one on the Starlet goes to the steering rack and the other on the Corolla goes to the steering pump. I would love to be able to reconnect it to the steering rack, but I would have to either adapt the Corolla rack and fit in the sensor or either adopt a Starlet steering rack to the Corolla.
What do you think?

you can see the hole where the sensor is located on the Starlet. Could you please help me to understand if it would be possible to tap it? Maybe even without getting it off the car

I'm not 100% on how the whole set up works, will need to do a bit of reading on the subject before advising.

As far as tapping into the rack without removal, you would need to be sure you aren't going to introduce any swarth/metal filings into the rack itself. Don't think it would be a huge issue but best to err to the side of caution.

I removed the sensor on the Corolla steering pump. I have on the side and unfortunately the sensor hits a metal plate that means tapping into the rack won’t be useful without the metal plate. I will upload a picture later.
The best thing to do would be to buy an extra rack, but again it won’t work without the internal part. It would be better to create the steering pump bracket that fits the Starlet steering pump bolts. The only problem is that the Corolla steering pump hits the Starlet bracket and doesn’t allow the belt to go on. Do you think that anyone on the forum has an extra steering pump bracket? This way I could do the work without using the one I have on the engine.

 

[Jay]

I think I understand.

The corolla pump has issues fitting to the 4efte, I've sourced a few bits for @aubreygil there today.

Brackets shouldn't be an issue but you'd probably need the same hoses and bottle that he needed?

Not at all. I would just connect the hoses from the inlet that that usually in the Starlet goes to the steering rack straight to the steering pump. It is the exact system, but it just feeds steering oil pressure from two different points in the same system. You can see it in the description pictures I posted at the beginning of the thread.
You can see from the pictures I took that tapping the steering rack wouldn’t be possible because it needs the female metal plate in the hole.

 

[Frankieflowers]

I want to create a plate that merges the Corolla pump holes to sit above the oil filter. There is plenty of space.

Just for reference, I think this is from a glanza.

Thank you for the pictures. I confirm it is from a Glanza.

do you think I could swap the upper part of the steering pack with the Corolla one?
I think that if you screw it off, the whole thing would fit the left hand side Corolla. Maybe someone has a Corolla E 11 4efe steering pack to try?
Ever since I bought the engine from a half cut, I never figure it out if the steering pack and the drive shafts were swappable between the Starlet and the Corolla.

Only retrieved the rack from the container today, I'll be draining it at the weekend to remove the pipework so I can unbolt this union to investigate. Will update with pics.

Well thats the rack attacked this morning. Pics attached for reference. Looks like you could theoretically swap it for a corolla version but you would need both on the bench in front of you to be 100%

Thank you for the effort!
My concern os both if the parts are compatible and if ot would work on a FHD as my Corolla.
BTW my Starlet steering pump started to leak on the internal side (right side). Could you help me find one? I couldn’t find any. Also the Starlet AC compressor is leaking from it’s engine through the screws…gosh.
