1UZFE injector specs

Can someone tell me the specs of the 1UZFE injectors. AND their numbers?
All I know is that they're 440 injectors. I need to know if they're low or high impedance, and their model numbers. Also would be good to know what they could be upgraded too.

They are 440cc as you say, but why do you want to upgrade them? Are you planning on turbocharging it straight away? The thing I mean is, that because there is 8 of them, the flow potential is there for 400hp...

I still don't get why you wanna upgrade them at the moment, I'd be more worried about just getting the thing running first

I need to know the specs of the current injectors so I know if the computer will be able to use them. Otherwise I'll have to use other injectors. If I know what injectors can go in there then that'll make that choice easyer.

Pete
Can you pull one off the motor and check the part number?
You may be able to find the info by doing a search on the web with the part number - probably a Nippon Denso unit. You could try asking on ClubLexus in the SC400 Section as they run the same 1UZ there in the US.
How did you go finding 1UZ Soarer mounts?

Have you ended up upgrading your injectors yet Jamie? How come you're never on ICQ any more?

I've been told to take the engine harness off it now, so I'll have some room to get the numbers off the injectors.

1UZ-FTE, sounds correct.
If they were 440's (about 80hp per unit) the 1UZ would have enough fuel in stock trim for 650 HP. Naaaaaaa, wrong answer..
8 X 250 = 360 HP. More like it.

440cc units are on JDM JZA80 TT (2JZGTE) Supras as well.

They are 251 cc/min,good for up to 400hp in theory.
They are almost certainly high impedance,but check by using a multimeter and touching the prongs on to the two pins that are revealed when you pull the plug of an injector.(should read 12-16 ohm)

Great, High impedance saves me $100. 400hp might be ok for a little while
I'll try and find a multimeter to test them.
