Using Supra Injectors

This is the last thing I do to my L28ET, if this fails I'm ripping it out and declaring it junk.

 

It seems like injectors 3-4 are stuck open. So much so that they are washing down the cylinder walls. The car runs pretty well at higher rpms, but will run like crap if turned off then back on in a short amount of time ( <1hr). When I removed the plugs, those 2 were the only ones not a nice tan color, and they reeked of fuel (not oil).

 

From what I have gathered so far is that you need a smaller lower seal (does anyone have a part number/description?) and a slightly large hose to slip over the o-ring (I know you're supposed to use an o-ring fuel rail but I've heard of people running them like this). Is that about it?

 

I will be able to retune my MS easily with my WBO2.

Thanks,

Mario

I am running supra injectors and used the stock replacement "O" rings for the supra. I had my JSK fuel rail drilled out for "o" rings but I see no problem running them with a hose and clamp. I would not try to slip the hose over an "o" ring. just get rid of it and use injection clamps instead of the cheapos

Anybody have a source for these injector clips? I'm gonna need them too....

You can get them at the junk yard. Any mrk3 supra will have them. ALso other Toyota's will have clips very similar.. you may have to trim a notch off the injector itself and then the clips click right in.
