    Pretty sure you wanna stick with high impedence.. Do a search jricker just posted a chart for different injector sizes in a thread. Are you planning on doing any tuning to this car? If so I would recommend a quarterhorse and a wideband setup. Also check out eectuning.org. It's all about tuning. And people actually answer your posts. Just getting my tune finished up from a guy on that site via phone and email.

    You will need high impedence injectors unless you want to buy a pms and a low impedence driver. the question about the injectors size can only be determined by your expected hp output and remember, you never want an injector running above 85% duty cycle
