i just got a vtec head for my 99 dx. if i got a vtec controller do i still need toget a vtec solenoid and an ecu? also could i just put on the head and be cool to drive for a bit with out hooking up vtec?

you're cool driving without vtec hooked up. The selenoid should come with the head...if not...you'll be losing all your oil

i got it off ebay. i knew it didnt come with the solenoid. but could a vtec controller replace a vtec solenoid and a new ecu? if not what type of ecu is good? an ex?

No. You cannot replace the vtec solenoid with a vtec controller. The Ex ecu would be ideal.

Look on your head at the passengers side end there will either be this thingy with a green cylindrical top or a giant hole where that doohicky should be. If there is a giant hole get a solenoid and hook it up. To get VTEC to work you will need either a VTEC ecu or a vtec controller like a VAFC. Make sense?

You need the vtec solenoid.... Without it the head swap is useless.....

The solenoid should be on your passenger side of you head.

ok ill check that out. can i use an ecu off a dohc car like an si?
