ok, so research is going slow, the more i read the more confused i get. i'm going to start buying parts soon, but have a few questions.

injectors: in the diy faq, it says the 7mgte supra injectors are high ohm, direct fit without resistor box...then right below that it says they're low ohm...which one is it? when it says plug and play replacement does that mean just the injectors are needed, the mazda clips fit?

oh, and FD Rx7 injectors aren't on the list for PnP, would they work or no...ironic i only have injectors that don't fit.

Megasquirt...i know i should search for this, but i can't seem to find an answer. who builds a pnp for the NB? braineack? (his FS thread only says NAs and i didnt' see an answer the the guy who asked about NBs) DIYautotune? i'm sure i need a certain # of posts to actually pm braineack, but i tried anyway.

while i'm at it... EGT sensor. MS doesn't need it to run the car, its just nice for additional fine tuning and monitoring, correct? (probably not but i tried)


flame suit on, have at it.

Read the list again. There are two different injectors for the supra 7MGE




Complete list of Miata plug and play replacement injectors (“F” connector):

HTML Code:
Year Make/Model Engine Size/Color Part #
87-88 Toyota MR2 4AGE NA 213cc – Beige Top #23250-16080 
89-91 B2220 Truck 224cc - Yellow Top? #23250-74040? 
99-00 Mazda Miata 240cc - Thin Red Body #195500-4430
Toyota 4AGE 250cc – Green Top 
Toyota 4AGE 250cc – Violet Top 
94-97 Mazda Miata 254cc - Tan Top #195500-2180
01-05 Mazda Miata NA & TURBO 265cc - Thin Lt. Prple #195500-4060 
Toyota 3SGE 295cc – Green Top 
89-92 Toyota Supra 7MGE NA 305cc – Light Green Top #23250-70080
93-95 Toyota Supra 3.0L 312cc - Maroon Top #23250-46030
Toyota 3SGE 315cc – Pink Top 
90-92 MX6/626/Probe Turbo 326cc - Gray Top #195500-2150
89-91 B2600 Truck 326cc - Gray Top #195500-2150
Mazda 323 GTX TURBO 360cc - Black Top #195500-2130
Celica/MR2 3SGE NA 370cc - Green Top #23250-74160
Mazda RX8 420cc - Yellow Body #195500-4450
Subaru WRX 425cc - Lt. Blue Body #3920 
89-92 Toyota Supra 7MGE TURBO 430cc – Black Top 
89-92 Mazda RX-7 NA 440cc - Blue Top #195500-5740
89-91 RX-7 NA 460cc - Red Top #195500-2010
Subaru STi 540cc - Thin Pink Body #3910 
89-91 RX-7 TURBO 550cc - purple top #195500-2020
The same connector shape can be found on low ohm injectors, but they require wiring in resistors to increase the resistance and filing down the tabs on the sides of the injectors.

Direct fit LOW OHM injectors (“E” connector):

89-92 Toyota Supra (7MGE) NA - (295cc – Yellow Top) - #23250-70040
88-91 Toyota Collora GT-S Turbo (4AGZE) – (365cc – Red-Orange Top)
92-95 Toyota Collora GT-S TURBO (4AGZE) – (365cc – Red-Orange Top)
86-92 Toyota Supra (7MGTE) TURBO – (430cc – Black Top)
Toyota MR2 (3SGTE) TURBO – (430cc – Black Top)
High Ohm vs. Low Ohm tabs




So yes, the lime green top supras are plug and play. The yellow fit but are low OHM.

Several RX7 injectors fit. They are listed. Becareful with the Sube injectors, I'm not sure if anyone has successfully used them.

You should PM Brain, you'll likely need to wire it parallel.

MS doesn't need an EGT sensor.

EDIT: wow...ok i see it now, the 7mge turbo is 89-92, the 7mgte is 86-92. i didn't know they had different turbo engines.

Yea, i was beating on the SUV and drove up on a 4wd Sheriff. EEEERrrrrrrrr. Braked it hard.
It would be fun if they wern't there.

Funny thing, we were heading to Veil, and a sheriff pulling a rescue station slid sidways blocking the whole highway, hit the rail, and wound up facing the wronge direction. He is lucky to be alive.

Yea I bet ya, he needed new shorts right along with me and my girl.

They also have the biggest RABBITS! I have ever seen. I would so barbeque one up. I think they missed the turn near Al-buuur-quirk---yyy. LoL
