Installing a direct port Water injection. - 6G Celicas Forums

Hello everybody,

i got a few questions again and might need some help

I ordered a "Direct Port Water injection" from here:
Enginerunup

Now i have to see where i can mount the nozzles on my intake manifold....

Well my mechanic wants to place them at the bottom end:

But i think that might affect the full atomization process?!?
As it is a direct port WI it should be one nozzle per runner. But where. And as far as i heard there is not much space to place them!!!

Here is a pic of a ST205 engine:

and especially of the runners

So where would you place these nozzels? And keep in mind that the nozzles have these huge checkvalves... so they are quite big.

And where is ourAir Intake Temperature Sensor?

cheers Joerg

Here are 2 more pics.

I turned the angle of the first pic, because i think this is the angle how the engine is installed or????

and here is another pic i found: That should show the right angle of the engine as well.

I hope somebody might be able to add some advice. Thank you

Joerg

Glad to hear things are coming along. As for where to mount the
injectors, it seems to me that there is only about foot or so of a
difference on where you are debating on putting the injectors. If this
is the case, and let me know if it isn't, then I would put them wherever
I is easiest, as there would be no difference. There will still be
plenty of atomization either way. If you think about how fast the air
is moving through there, the time for atomization/evaporation is
extremely minimal either way, as it is pretty much so no matter where
you mount them. It is not an issue. Since you have the direct port kit
with the four smaller nozzles, the mist is extremely fine already.

I am trying to post this on the forum, but the registration page isn't
loading for me. I will keep trying.

Thanks,

This is what Greg told me via email. It looks like that there wouldn't be much difference where to mount them alaong the runners. What do you think?

It may be noobish, but what is Direct Port Water Injection?

water injection is a form of chemical intercooling system really to put it simple....it cools the intake charge in high boost applications so that you prevent detonation (i have minimal understanding of this but thats my general idea of it)
direct injection means that it fires directly to the combustion chambers via the intake runners (4 / 1 per runner) indirect would be spraying 1 nozzle into the intake tube (not very accurate and even, less tunability)

where your mechanic seams to have it looks ok...i might set them a little farther up the runner by an inch or so just to insure there is enough metal near the manifold to prevent warping or cracking....
but along the backside of the runners seams to have the most room

This is what i just wrote to Greg as my mechanic told me that there would be enough space to mount them higher but he cannot reach this area with his fingers or a tool to tighten the nut.

> Hello Greg,

thank you for your reply. Well for me it seems that the area where my mechanic wants to mount the nozzles is "very" close to the chambers!!!

But the problem is as far as he told me. That he has got a problem mounting them higher up the runners as the nozzels are build up like a screw and a nut. That means that he only has to drill a hole and then hold the nut on the inside of the runner and start screwing in the other part from the outside.

BUT the problem is we would like to get up higher with the nozzles but his fingers are not 20 cm long.

Do you know what i mean. How did you achive to mount them in the middle of the runners. Please take again a look on the forum pictures i posted.

if you get a long wrench and heat it with a torch and bend it to reach up into the runner, it can be done
