I promised my wife I wouldn't work on the car tonight. She has been incredibly understanding through this whole project, at the very least I can give her an evening of (almost) undivided attention. She is working tomorrow and I will be working on the car and get some videos then.

I was able to wrap up several loose ends this weekend. The power steering leak I knew about and already had a new reservoir on order so that was an easy fix. The coolant took a bit more work, it turned out I didn't have the steam vent hooked up right and it was bleeding though the overflow. It only took me four trips to The Home Depot to get that straight.
Of all the issues I had the lack of speedo (which I was the most concerned with) was the easiest to fix. As I came to learn every IS300 in 2001 used the wheel sensors through the ABS module to read speed. From 2002-2005 this only applied to the auto cars. Factory manual cars had a VSS on the trans. What makes things nice is that all the pins are there to make the manual read speed like an auto. I followed the instructions here to get it working.

Next on the list is diff bushings. Mine are blown and get a really bad oscillation under part throttle. If I am off the gas or under heavy acceleration everything is fine.
I also took a quick video of the car idling in the drive with the new exhaust. Enjoy.
As it was over 90 today I need to start looking at A/C soon.

I meant to post up last night but didn't even get home till almost 1 and still had to get up for work at 5:30. At any rate after work last night a buddy of mine helped me get the diff bushings out, then make and install the new ones. His dad owns a diesel garage and let use a bay after hours. Needless to say there was plenty of room.
It didn't hurt having the right tools, and by right I mean really big and beefy!
We found the best way (only way that worked for us) was to use an air chisel and drive the old bushings out. I knew they were bad but didn't know just how bad. One of them didn't even have fluid in it anymore. We did a pretty good job of destroying them on the way out but still had enough there to get dimensions from to make new ones.
I decided instead of aluminum I would try with Delrin (high density plastic). This should give me enough strength but still allow just a little bit of give to help keep the vibration down.
They turned out well, were pretty easy to install (a lot better then removing the old ones). I saved all the dimensions in case these don't hold up and I have to make them again out of Aluminum. Time will tell.
I also figured out today the "bucking" I was feeling was an issue (or several) in the tune along with the bushings. The car is at the shop now and will be getting tuned tomorrow hopefully.

The car is off getting tuned now, but I'm not sure if he was going to throw it on the dyno or just street tune.
I did look te other day and the fitting I had crimped on the end of the hose didn't have a part number on the invoice. The other fitting at the rack I need to look. It was M16x1.5 to male -6 JIC if IIRC.
The delrin bushings are one of a kind. I bought delrin and had a buddy make them off the old ones we pulled out. I haven't given them much abuse but don't see any reson they won't hold up.

looking great! If you could do a write up when you get time of how you used the lexus ecu and tied in with the gm pcm for the ac and such, I would love to download it!
Thanks!
Thanks!
