Thread: Bought 505-606N kit, what else is needed?

    Default Bought 505-606N kit, what else is needed?

    Hello. I just ordered the Holley HP EFI 550-606N kit for my '92 Mustang turbo car. I was wondering what else is needed for install? I'm saving up for the 100 psi pressure sensor, 3 bar MAP sensor. In the future, I plan to save up for the Holley dual sync distributor. Also, are there any places you guys can recommend that I can research and see how other people have installed this kit on their Fox body? Thank you.

    ETA: kit number typed wrong. Really 550-606n

    It includes the CTS, MAT, MAP & WBO2 sensor too. If you want the optional fuel & oil pressure transducers, you'll have to purchase those.
