These are USED side feed injectors commonly found on the Toyota 20-valve 4AGE engines. These particularly came from the intake manifold from the silvertop version of the 20V.
They are for sale here on EBay.

I highly, highly recommend getting the injectors professionally cleaned and flow tested. Most of them offer documentation (yay!) and replacement o-rings as part their service. I included the original o-rings in the box in case of needing to match sizing (that weren’t damaged).
Here are a few companies to check out for the mentioned cleaning. Each have their pros and cons depending on what you’re looking for.
DeatschWerks – OK
InjectorRX – TX
MotorWest Performance – CA
RC Fuel Injection – CA
WitchHunter Performance – WA
Happy tuning!
