Whats the deal with larger injectors, anyway?
Unfortunately, almost every car company uses different injector plugs. The most common third party injectors for the K-Series, RC Engineering injectors, have a different plug and need adapter clips soldered on. Comptech does not want to cut the wires and solder on adapters. Power Enterprises makes 510cc injectors that fit, but they are expensive. Comptech has been experimenting with less expensive alternatives. They tested 470cc Marelli injectors that could be used with a small alteration to the connector. They also tested modified stock injectors and other modified Honda injectors that can flow up to 530cc (stock is 310cc). Bottomline: if you use K-Pro and install your own pulleys and injectors, you can use anything you want. If you want official upgrades from Comptech, they will likely have a solution that costs less and is plug-and-play.
