One of my fuel injectors in spewing out gas, i replaced the seals and o ring with some off a mr2 turbo. And one of the injectors is still spewing out. I think the injector is bad. Can i also use the mr2 turbo injectors them self?

no MR2 turbo injectors are low impedance. are you sure you didnt just cut the o-ring. its easy to do if you dont lube them and walk them in.

not only that MR2 turbo injectors are side feed

Yeah my buddy who knows more about this than me did them. Still only the one is spewing out.
But the 5sfe o ring fits?
What aftermarket ones will fit then? or from other cars
7MGTE?

Would these work?

Alright, what in the HELL is going on here?????

First off, what engine is are these injectors in? RedTop / GreyTop or BlackTop BEAMS? I'll take a wild guess it is a Red/GreyTop? Seeing how this is the 6GC forum...

There is no way in hell you'd be able to use injectors from any MR2 Turbo on a BEAMS engine. The O-rings, top & bottom, are significantly different in design in their own right, and the injectors they are for are even more significantly different. Not only will the ECU not be able to make heads or tails of them, their impedance is different, the way they are fed is different, the way they seat is different, the fuel pressure they are designed to operate at is different and the volume of fuel they are designed to flow is completely different too. Not to mention that the spray pattern is totally different too. (Anti-flame statement: don't any of you dare say that the spray pattern of injectors is not important. Do your research on the topic. Toyota/Denso as well as all the other injector manufacturers spend millions upon millions of Dollars/Euros/Yen/Seashells on injector R&D...not just for sh!ts & giggles either.)
RedTop BEAMS injectors are *supposed* to be in the 360-380cc range. I say *supposed* because in my own personal wtf-is-up-with-BEAMS-injectors I've seen some different figures. They all came out to show different flow rates than what Toyota/Denso say they should...but in any case the numbers match across the board for all RedTop BEAMS injectors I have tested. So no biggie there.
Sticking in a bunch of 540cc injectors is a terrible idea. I am assuming you don't have a turbo setup on your Red/GreyTop engine. The OEM standard-issue RedTop BEAMS injectors already flow a bit too much fuel as-is. But keep in mind, this is Toyota we are talking about...legendary for having somewhat rich air-fuel ratio injection maps. They have their reasons to prefer as ~9 to 12 : 1 range in air-fuel ratios.

The exact name for the fuel injector design that Denso provides the Red/GreyTop engine, escapes me at the moment, but they are indeed the skinny plastic bodied ones.

Injector part number = 23209-74190
Lower injector O-ring part number = 23291-41010
Upper injector O-ring part number = 90301-07024
Fuel rail spacer part number = 90561-08051

Do *ESPECIALLY* not screw around with whatever injector O-rings (they are sensitive little bastards sometimes) & spacers you have just lying around and are not sure if they are actually the correct type/model for your setup. There are more cars than I can count on my 2 hands that have caught fire and burned to a crisp because of owners being complete idiots & using "whatever" fuel injection parts from "whatever" they had lying around. I'd told almost all of them "I told you so!", so DO NOT screw around here. You have a serious fuel leak issue going on here.
If for some reason you've planted Money Trees in your yard *OR* are made out of money, I would A) like to know where you live & B) you have my blessings to screw around with the fueling & burn your car/engine/self to a crisp. I tend to think none of these conditions apply to 99.99999999999999999999999999999999% people on this planet. So use proper care & caution here.

You can of course use whatever the heck fuel injectors you like, so long as the specs & measurements all add up the the OEM fuel injector (pics attached). If you are using all OEM injectors, fuel rail, intake manifold, fuel pressure regulator, fuel pump & filter and have nothing else funky going on like a turbo/ITBs or forcefeeding of any other kind, I see no reason you could argue as to why you should use aftermarket over Toyota OEM parts.

The absolute best thing you could do right now is to take all 4 injectors off and take them to a reputable fuel injector cleaning/servicing shop...and see what's what. One injector gushing could, *perhaps*, be from a blockage in the little strainer at the top end of the injector where it is fed fuel. Could also be a stuck needle inside the injector. Either one could be a catastrophic situation for the injector itself...and eventually your car...should it catch fire.

Do *NOT* screw around with things here, as I've highlighted up ^^^ there.




No.

Well the o ring parts all match mulmultiple engines so could a 5sfe one work?

lol///
