hi i have a r33 that has been having a power drain. I have since found out the drain has been coming from my new head unit being partiacally on all the time. I wired it up at the back from a souce that gave power all the time so i could save stations. But by doing this it drains my battery in like 40 hrs. I remember there was another source of power but only when the ignition is on. Is there a way i can get just enough power to the head unit to save stations but not drain the battery?

one of ya's has this done to your car how did you do it?

thanks

    • If there's enough meat in the housing where you want to put the M12 adapter, then do it, but be aware that if/when you f**k that up you'll probably be repairing it before doing anything else. I'd just drill it out and tap ina 1/4" thread. No need for rocket surgery when the next most obvious thing will do. You could throw a 1/4 x 1/8 bush in there and use the same fitting you intended to use.
    • Is the only issue that the oil catch can is getting filled on hard runs? I'd be thinking more about oil control issues rather then the head lifting, especially as you aren't seeing spiking in the coolant pressure.  Do you need restrictors in the head, or better drains from the head? Does the sump need venting to the catch can?
    • Tried to make 1/8npt threads into compressor house of the turbo for my EBC. Threads got fu#ked and ended up with and elongated hole, so I do have good amount and nice threads 90% of the hole but 10% I only had 1-2threads there and rest of it is flush on that side of the hole.. So my idea is to do M12 x 1.25 to AN4 with braided lines instead of 1/8npt to 4mm vacuum silicone hose.  and hopefully get a better thread. M12 is quite big and AN4 is a little bit bigger than 4mm (4.9mm inner diameter braided PTFE hose). but this should work. Thoughts? Otherwise I will weld and adapter onto the turbo.   
    • Looks great, I hope everything is working well after all that time!
