jackherer 543 Posted March 27, 2008 1.9 injectors are yellow and flow more than blue 1.6 injectors. 1.6 GTI engines are XU5JA Share this post Link to post Share on other sites
WhartonMotorsport 0 Posted March 27, 2008 excellent, cheers. How much higher is fuel rate on 1.9 compared to 1.6? Also, is 1.9 fuel pump and higher flow rate than 1.6? cheers again dan Share this post Link to post Share on other sites
Tom Fenton 1,541 Posted March 27, 2008 Fuel pump and regulator is the same. There is no advantage putting 1.9 injectors on a 1.6 with the standard ECU if that is what you are thinking, all it will do is overfuel. Share this post Link to post Share on other sites
