I'm planning getting the car re-mapped soonish. I quite fancy putting a set of these injectors on but is it just a straight swap? Or do I need new fuel rails and wiring etc?

Will also have a walbro fuel pump, decat and STI TMIC to help.

The car is a 2003 WRX.

Cheers.

 

straight swap over, but needs to be done just prior to map, but not worth it unless you fit a bigger turbo as well.

 

As Above.....The WRX you have injectors can take all the air TD04 can throw into the cylinders

Also a b*gg*r of a job, if yours is the same as an 02 STI.....

dunx

 

Oh, I thought they might make a bit of a difference with the standard turbo.

A new turbo, not sure what yet is planned some day, so should just leave the injectors till then?
