AC compressor rebuilt. A pretty easy process. Make sure to replace the O Rings on the speed (lock) sensor and on the back housing's bypass manifold.

System is still leaking somewhere. Seeing how bad all of the orings were on the compressor I'm going to go through and replace as many as I can on the system to see if it fixes the leak. The leak is certainly slower than usual.

As expected after watching the Binky video about the ID 1050x injectors, they hit the bosses in the cylinder pretty hard. Contacted ID and they are shipping me adapters to try and move the injector body upwards. It looks like this is a configurable option from the get go, just isn't the listed part number for the 3SGTE.

The PN is 1050.60.14.14B. Has both a top and bottom "hat".

I would not have thought to do that when reinstalling my AC so thanks for pointing that out.

A few sneaky ones: High pressure side sensor is not a tapered thread but uses an O-Ring to seal. Use a wrench on the line's fitting when removing to make sure you don't twist the crap out of the line.

There are also four in the cabin on both sides of the expansion valve. I haven't done those but I figure they are in better shape than the ones in the engine bay. Also my vehicle had the expansion valve recall done in 1993 so it has newer rings than most of the system...kinda :wink:

I just grabbed a universal A/C O-Ring kit from the local parts store and it had everything I needed.

After testing some more I believe that the system is actually sealing well under vacuum its just the manifold gauge set I have isn't the best. That's what I get for buying the cheap stuff :(

Are the expansion valve ones somewhat accessible or does a bunch of stuff need to be pulled out to get to them? I've had the lines open for ~8 years and the firewall connectors have been totally exposed for the last 4 which I'm guessing isn't great for them.

You essentially need to pull the evaporator core to get to the expansion valve. You should replace the valve (and possibly the core) if your lines have been open that long.

The core is the one inside the HVAC boxes in the cabin right? Sorry I'm really bad with A/C stuff. Thank you for all the pointers.

Sorry for the lack of updates. Things get in the way.

:bangshead:

ID1050X's installed and wired. I initially tried to use the RacerX OEM FPR adapter but it's a headache in a Celica.

Went with a new external FPR from Bosch/Radium. Now wheeerrreee to mount it?

I went with the now vacant EGR location. Here is the process of making a bracket to mount the FPR on top of the EGR delete plate from Circuit Sports:

Getting this bracket machined will be expensive so I'll probably get it printed in Ultem 9085. Good enough for airplanes...good enough for me.

If anyone wants the file, let me know. Pair this with M4x0.7x12 4x and M8x1.25x25mm x2.

Adapter mounted on engine:

It needs some tweaking to make it a bit more level and to move the return hose barb away from the intake air pipe for the IACV. The idea is that there will be a 90 degree coming out of the rail where there currently is a 180 and then another 90 into the FPR.

Very clean, good location. - Is that regulator non adjustable?

Correct, not adjustable, but a reliable and OEM Bosch regulator that can be bought at any parts store if it ever fails. 43.5 PSI. I also have an electronic fuel pressure sensor directly after the fuel filter. Now that I am using this FPR housing it might be better to move it to the port on this housing.

Well making an AN line between the rail and FPR are out of the question. I'll have to use some 30R14 here with hose barb adapters.
