the denso pump thats in the car is a 380, so how is that a down grade and 2 there are 2 differnt 255 pumps. a high presure pump and a normal. the high presure is a upgrade for the na cars the normal is the turbo pumps. now with all that said just because the fuel pump can flow that amount of fuel at set psi does not mean the injectors will be forced to consume that much fuel. remember these are return systems and the motor will only consume the amount needed for set tune. and ya ill take 45

the pump is also known as the supra tt upgrade pump. with the 255 the car would start to starve at the top end. swapped to the denso pump and my starving problem went away. the 255 was only about 1000 miles old

yea, they are big but they fit ok. my main point is the walbro is too much flow for a stock n/a car. the additional volume will increase the pressure at the fuel rail and produce a mixture too rich for the car resulting in less power and worse fuel economy unless he has a standalone or piggy back to tune fuel with.
