The 1JZ-GTE always had the same rods, VVT-i or not. Same goes for the 2JZ-GTE.
Only the non-turbo versions of the engines got the lighter/weaker rods when VVT-i was introduced.

While there are only 2 different types of TPS used on the MA70, they were not always the same between N/A and GTE, and they did not change for the 89 model.
89452-28030 = 86.5 - early 87 7M-GE and 87 - early 89 7M-GTE (Replaced by 89452-20050)
89452-14050 = late 87 - 92 7M-GE and late 89 - 92...
I can't remember if I did any of the original art in vector or not... definitely not for Dark theme, but the "SM" logo used on the light theme may have vector available.
I'll look, but I can't guarantee it.

It would work with most stuff, however a few things would be different, like the knock sensor connectors, and the O2 sensor connector, as well as a couple other things.
Really if you want to just plug and play, get an 89 harness.
Jeff
Starting in 01/89 the subframe/mounts changed to the newer style.
I've never seen an 89 with yellow connectors, people have said over and over that they exist, but I don't believe it.
From all the 89's I've seen and/or worked on, they were all exactly as the wiring diagram showed.
I think...
I'm not sure what the dealer network is like the in USA, but there are literally thousands of the Denso Made in Japan 90915-20003 filters sitting in the USA, they're the only filters I run in my Toyotas.
Jeff
I think probably mostly age and corrosion, combined with bad luck. I've seen some very clean, non-rusty cars with stock power and cracked subframes.
Pretty much any A70 subframe could use reinforcement, but the 86-88 subframes need it even more.
Jeff
Measure the impedance of the injectors and have them flow tested. This is the best way of knowing what you have.
Also, contact him, and see if he had them flow tested or what his source is for knowing these are 550cc injectors.
For all you know, someone pulled a fast one on HIM.

Also, I'm not sure if you saw this article:

I wrote regarding this, it may be what you were originally thinking of, but it will answer even more of your questions.
Jeff
There is nothing in the VIN that will tell you specifically the destination of the car. All Supras were manufactured in Japan and shipped over here.
What will tell you the destination is the model code on the firewall (86-88) or driver's door jam (89-92). The code will be MA70L-xxxxx, the last...
Needs different wheels, a different spoiler, and the correct rear diffuser to fit into the rear there. Not a huge fan of the Top Secret widebody in black either for some reason.
My brother was going to get the Top Secret kit for his Supra, but ultimately decided to go with the TRD widebody...
Sometimes Toyota splits manuals into 2 volumes later, even though originally they were only 1 volume.
I've never checked for the Supra, but just saying it does happen. So even though you may have a single volume RM for one year, someone else may have it in 2 volumes.
Jeff
Not sure about all of the stickers on the car for different years, but even my AE86 has a 10,000 mile / 16,000 km oil change interval. Toyota actually lowered that over the years, by the time the 93/94 Corolla came out Toyota was at a 7500 mile / 12,000 km oil change interval.
On new models...
I was actually looking for what was after the MA70L, I knew it was MA70L, lol.
They don't list any USA models as having the kg/mm^2 gauge, but the EPC could be wrong for very early models I guess.
