Lagos' ct20b install Options

[lagos]

Here are the pics from the install...

I decided to remove just the turbo and not the entire exhaust manifold, to help avoid any issues with stripped exhaust studs.
I also had a brand new Hose from Hell that has been sitting in my house for months waiting for this day.... and wouldn't you know it, I didn't think of bringing it with me to my friends house where the installation took place. oh well.

Removing the ct26...















Here is an interesting picture of the effects of washer fluid injection over a period of time. the turbo on the left is the new ct20b and the turbo on the right is my ct26. You can clearly see a white precipitate that has formed as a by product of mixing washer fluid into the combustion chamber.
It also looks like there is a bit of an uneven distribution of the washer fluid as cylinders 1 and 2 have a lot more of the white percipitate than cyl 3 and 4.

Sam buttoning a few things up...

I wonder what kind of effect that white residue has on o2 sensors. Why dont you try running a mix of straight methanol with water and see if that gives the same effect?

I have been running the injection for years, and never had any issues with my o2 sensors. So its safe to say its fine for that.
Probably not going to remove the turbo again just to check a different mixture.
There is really nothing wrong with the white residue, just something that happens.

So the white residue is from a mixture of the liquids? Or is it fuel deposits? I am just asking, I wouldn't know.


Also, I wanted to ask if you or anyone else happens to know what the difference is between the CT20b and CT26? Because people are telling me after switching to CT20, it pulls so much harder and it allows them to boost at higher psi. Is it just cheaper to buy a CT20 and run with that? Or is it actually better? Because I see what kind of HP upping the trim on a CT26 to 47,50,56 and 60-1 and it looks pretty good, especially for just driving on the street (way better than that actually). Because I don't know much about turbos, but by comparison, the housing appears a bit of the same. I ask because the only turbo car I have right now is my MR2 and it has the CT26. I haven't had a chance to see what the Japanese ones have, however I noticed that on a stock vs stock test, they are faster than the Supra RZ MKIV in the 1/4 mile test. I thought the Supra uses the CT20 as well. So I just wanted to be schooled a bit.
