I hope this R&D help my members. This is fresh out of the oven. The 7MGE injectors are from Toyota Supra from 1988-1992 AKA MKIII N/A motor. There were two sizes produced. Yellow Tip is 295 cc/min and Green Tip is 315 cc/min. I used a highly precise caliper (professional) to do all the measurements. Here are the of the injectors:

Stock 1UZFE Injector:
Code number: 23250-50020
Overall Length: 2.800″
Injector Tip Length: .260″
Injector Inlet Length: .614″
Injector Tip Diameter: .368″
Injector Inlet Diameter: .415″
Injector Opening:2
Injector Connector: Type F
Flow Rate: 251 cc/min
Impedance: high 13.8 ohm

Stock 7MGE Injector:
Code number: 23250-70080 Light Green Tip
Code Number: 23250-70040 Yellow Tip
Overall Length: 2.810″
Injector Tip Length: .260″
Injector Inlet Length: .614″
Injector Tip Diameter: .370″
Injector Inlet Diameter: .416″
Injector Opening:4
Injector Connector: Type F
Flow Rate: 295 cc/min Yellow Tip
315 cc/min Light Green
Impedance: High 13.8 ohm

Basically the two injectors are identical. I got the 12 used injectors for a great price. They will be send to a injector specialist for cleaning and balancing. They are direct bolt on to the 1UZFE.

Stock support 8 psi
Yellow Tip support about 10-11 psi
Green Tip support about 12-13 psi.

Those injectors are like gold to me. The are in high demand and especially the Green Tips… very hard to find. Anyone have a 3SGTE injector laying around? I would like to compare them to 1UZFE injectors.

This is a freelance site with no support by huge companies.  I have been doing most of the R&D and technical write-ups by myself with my personal money and literally thousands of hours of my time.  I have taken extra steps to demonstrate in details how things are done.  Currently I am one of the few people doing Lexus V8 research and performance enhancement.  This effort comes from my personal love for this wonderful engine.  Most of the modifications are from trial and error. There's no cookbook for 1UZFE mods and its unknown territory for much of supercharger performance.  The parts, labor, web development and site hosting are 100% paid from my personal hobby money.  If you feel my efforts help you in any form, please do not hesitate to donate any amount of money to support this site. You have no idea how much I and the entire Lexus and Toyota community appreciate it!
