Ok now this might seem a bit of a silly question but I am a believer in "if you don't know then ask". I was just wondering on what injectors that you can use in a 1UZ. What is the standard size and what could be used as a "plug and play" set up? Where do you find them and how much do they cost roughly? What is suitable on a standard ecu and what other injectors from other engines fit straight in? How much do they increase the performance? I know that its a lot of info but if you even know the answer to one question then please tell me as any info is appreciated.

You probably need to tell everyone what you want to acheive.

If you are going to run a stock ecu then you won't have any control over the injectors so simply increasing the flow rate by fitting larger injectors will result in the engine running rich across a large party of the operating range.

To take advantage of any fuelling mods you really want to run a piggy back or aftermarket ECU so you can remap the fuel curve to suit any engine mods that you make. Even without engine mods you can probably gain some horsepower with an after market ECU.

James, there is no point in changing the injectors unless you have added forced induction and require more fuel.

Having smaller injectors than you need, means the engine runs lean and burns the pistons etc.

Having larger injectors than you need means too much fuel (which can be adjusted with an add-on ECU), but then the drops are still larger so don't burn as efficiently.

Having the right injectors is best! And that is just what you already have. :-)

Have a look at

Tells you what are plug and play, and which cars the injectors come from
