Default Supra Injectors

Hello all,

I recently bought some 312cc Supra injectors ( part # 23250-70080 ) having read on several different sites that the stock ECU can idle them and that they are a plug and play swap. I bought a new seal kit from Rock Auto and maybe that's where I SCREWED UP? I bought the seals for my 2003 Mazda not specifically for the Supra injectors.

When I pulled the old 265cc injectors it was apparent that the Supra injectors were way bigger. I didn't see any way that they would fit into the injector port as the diameter of the seal and the injector nozzle were much larger.

Anybody who has done this swap, can you advise? I didn't want to install without new seals even though the ones on the Supra injectors looked fine. What am I missing?

You have the wrong seals/orings.

Buy them from here; Denso Injector rebuild kits

Order the M1 kit and get at least 1 or 2 extras (because when you tear the top o-ring it's nice to have the spare handy).

Good guy and quick to ship.
