Any updates Supraguy? I was wondering if you are getting them new or used and where you were able to find a set. Let us know how everything goes. Thanks for being the guinea pig lol.
Arctic Cat injectors in a supra?

No, no update.
The supplier claims they are out of stock for at least a month.
That's why no updates, and why I haven't named the supplier, since I don't know if I'm even going to get these things,
or if I'm going to just get taken(they have my money)...

So did you end up getting these injectors? I see in your sig you list them as part of your upgrades. If you did, who was the supplier and what was the cost of each injector.
Yes, I did get these injectors. They are installed in my head(and have been for like 6 months).
Hopefully, I will get the chance to start the engine before Christmas. My supplier was Ebay.
Attempting to buy these from a few overseas distributors was completely fruitless; they would advertise them, but then say that they were on permanent backorder.
I would ask them when they might expect to receive some, and they'd say "I dunno, try us next month". I ended up buying two intake assemblies off of some Arctic Cat snowmobiles, and upon receiving, I pulled the injectors and resold the intakes without them. The thrid pair of injectors, I was able to buy on their own.

So, I thought it might be a good idea to update this thread, since I finally got to the point of starting my engine not so long ago.
Bottom line: The Denso 680cc #1001-87650 injectors work. I don't have any sort of data about what kind of power they make, but I can say that it idles quite smoothly.
I had them flow tested at FIC in Florida, and they all came out between 702 and 704cc's, so plenty of potential.
The nice thing about the nozzle, is that it is split into two outlets, firing out left and right of center by about 20 degrees, I would guess.
This looks to align pretty well with our intake ports.
Here's a video of the idle and rev, both open and closed exhaust.

After buying a couple of intake assemblies, then selling them off, I think I paid around $150, plus $20 for new filters, and $80 for flow testing.
I assume that they'd work in anything that takes top feed injectors with oem Denso-sized fuel rail openings.
These are low impedance, like 87-88 turbo 440's.
