Anyone know if 7mgte and 3sgte have the same injectors.
I have heard that 3sgte injectors come in side feed and top feed, the top feed being the same as 7mgte (430cc)is this right and do they have the same electrical connection?
Thanks.

No, the 7mgte injectors are rated by toyota at 440cc, but i flow tested mine and they messured 486cc on average. I don't know about the 3sgte ones, but i know one particluar model gt4 3sgte motor had 800cc injectors.
Oh, and the 7m injectors are top fed too.

Lots of confusion here.
Gen I 3SGTE injectors are 430cc/min and top feed same as the 7MGTE injectors. I can never recall whether they are high or low impedance but physically they should be a straight swap.
Gen II 3SGTE injectors are also 430cc/min but side feed
Gen III 3SGTE are 540cc/min and also side feed.
There were NEVER any factory 800cc/min 3SGTE injectors. TTE do 920cc/min but just a tad large for most street cars 
As for the flow rating. You have to have tested your injectors at the same pressure and same duty cycle to have any meaningful comparison. I believe the Toyo injectors are rated at 38psi at 100% duty but i'm happy to be corrected.

I have 7MGTE injectors in my 3TGTE and i also have 2 3SGTE.
Both the 7M and 3S injectors are the same size, top feed,plug
and color. I will be getting them all cleaned and flow checked soon so i can give the results then.
