OK, like always, looks like I'm looking for more trouble for myself. I have a set of Supra Fuel injectors. (BTW, I've check the price of these babies and they are at 171..00 each) The number is 2325046050.

QUESTION! Should I install these 4 Supra fuel injectors with a stock OEM fuel pump to my Turbo RAV4? OR, Leave the stock OEM injectors and install a performance Fuel Pump? (Performance fuel pump being a WALBRO 255LPH HIGH PRESSURE IN TANK FUEL PUMP GSS342)

Depends on your goal. Is it to lose power or fuel mileage, or both?

What engine do you have in your RAV4? You say turbo... so I assume you have a 3SGTE swap. But which generation?


If for exemple you have a 2e gen 3SGTE, the stock injectors are 440cc and side-feed. Now the Supra injectors you described (part number) are for NA 2JZGE (300-330cc) and top-feed...


Bigger is not always bigger. And it's valuable for both injectors and fuel pump!If yours do the job and are not near to be maxed, there is no need to go bigger.


For the fuel pump, Walbro are sh**ty pumps, they are noisy and have generally a short life. Better to pay a little more and get an AEM fuel pump with equivalent flow. Or better, a Denso fuel pump.... but it will be more expensive.

Sorry guys, looks like I lack some information. (remember, the post was at 2AM, after Irma pass PR and power was available) Now then, the engine, the good old 3SFE :wink New question, how much are the stock RAV4.1 3SFE injectors, cc? The fuel pump, AEM, is doable, but which one? https://www.summitracing.com/int/parts/avm-50-1000

Regarding the Supra Injectors, I guess they are a No Go.

Oh yes,. I will use my APEXI NEO AFC computer.

I was thinking of that. But I do have an Apexi NEO AFC computer that can take care of both.
Fueling a gas engine richer than 12:1 gives both a power and fuel mileage loss regardless of what controller causes it.
