Haha thank you for the kind comments guys, means a lot. And suprakidd I am going on vacation a while but later this summer we should get together or something, you could come to one of the local meets.
yes i most definitely will be attending supra meets, when you are back from vaca i should have my supra done or close to it.
Probably a silly question, but I just noticed you got the turbo coolant bypass hose (DM?). So your CT is just oil cooled?
Thanks Zum! I did bypass the coolant on the turbo just to simplify things. After some reading, it really isn't necessary if you use a good quality synthetic oil and cool the turbo off before shutdown.
I like the fact that it will thermosyphon after shut down and pull heat out of the CHRA reducing the chance of coking, but as you say a good Synthetic shouldn't coke 
My new ATI Damper. Notice the coating isn't 100%, bought it as a "blemished" unit for half price.

Decided to tackle the heater core before it gets cold out .
Dash pulled, got some new foam on the ducts, soldered up the heater core pipes instead of using the O rings.

Switched from the MaftPro to Lexus AFM..very happy with how the car drives now. It is going to need an SAFC to pull some fuel up top but other than that runs great.
Also swapped in some RC550s and a new CPS

Well its been forever but I have just been driving my car and enjoying it...took her out for a drive today and took some pics
Its actually an "A1 Cardone" rebuilt unit. Honestly though the only things re-used on it are the housing and the rotor shaft. It has a new gear, new coils/wiring/connector etc so its almost a brand new unit, and a lot cheaper. My old one was leaking oil inside and I didnt want to rebuild it myself only to be left with the old electrical coils that were cracking. To date I don't think anyone has been able to find a supplier for replacing these coils.
Heater core was not as bad as I thought, I was a little nervous about soldering the connections, I have never really soldered much before, but I tested it with air pressure and a bucket of water to make sure it wasn't leaking any.
I am happy with how the car drives with the lexafm and 550s, definitely need an AFC and AFPR or you will be very rich at high throttle/rpm. I used an SAFC2 and it works great, I am only running around 12PSI.
Thanks for the compliments

Well I want to make an update to this thread for the record books.
I haven't been on here in a long time, but my Supra is my daily driver.
Several months to maybe a year ago I noticed some occasional smoke from the tailpipe. It has since gotten gradually worse. It smoke relatively bad now, usually a big puff after decel and after long periods of idling. There is oil getting directly into the combustion chamber and I had the problem narrowed down to either worn valve guides/seals or piston rings, but it was a crap-shoot. A bore-scope showed oil around the valves but was difficult to tell if it was significant.
Good compression and leak down results pointed me towards the guides, so I pulled the head and had the entire head rebuilt. I even used OEM Toyota valve seals this time around. Several guides were out of spec, but not by much. Had all the guides replaced. Here's some pics of the process.
As you can see the pistons are soaked with oil. Unfortunately the cylinder head rebuild made no difference on the smoking problem and after pulling a plug the pistons were soaked with oil once again. Cylinders 3&4 are the worst, but all cylinders are getting soaked.
The clean edge of the pistons tells me that oil is getting by on the thrust sides of the piston, by the rings. I was unable to find any damage to the cylinder walls or any detonation damage to the Wiseco pistons, so I am unsure whats wrong here. Either way, a tear down will be needed. I dont have the resources to do that for a while, so I will be limping it along for another year most likely.
I should add that the car has no symptoms other than oil consumption and smoke from the exhaust. It runs and drives beautifully and has lots of power. Perfectly smooth idle as well.
