US Spec 1UZFE Injector

[Lextreme II]

Hey Gang,

I was helping one of the Toyota forum member on his Supercharged 1UZFE with fuel starvation problem. He posted his (not sure what it is. possible Celsior or Soarer injector, but its not US Spec 1UZ injector) and the part number or serial number is different.

The injector is about 2.75" from end to end. The injector number is 23250-50020 with Type F injector clip and the Non US. Spec injector is 23250-50010. Here are some pictures:

Try 4age 16v injectors

4A-GE injector is 250 cc/min. 3S-GE would be a better choice or 7MGE. 3S-GE is 295 cc/min and 7MGE is Yellow is 295 cc/min and Green is 315 cc/min

Aren't 7MGE Injectors lo-impedance?

If you are running more than 10 psi on the supercharged 1ufe, i think you should use the toyota 4agze injectors which is 369cc.

Peewee,

7MGE is high impendence - Yellow Tip - Plug right in
7MGE is high impendence - Lime Tip - Plug right in
7MGTE is low impedence - Modify injector clip and resistance....
