Sorry - assuming its the same as my Stagea where to get the ecu out you unbolt the cradle that holds it even though it looks as though it would slide out of the cradle. Maybe you should post up a pic ?

I think the later R34s (maybe Aug 2000-->) had this security cradle thing. It seems to be specifically designed to stop you removing the ECU.

Starion4me - If you have got a late R34, I remember that when we did get the ECU out, it messed up the built-in Nissan security/immobiliser thing too. Even plugging the stock ECU back in didn't clear it, so we had to short cut the ignition system in the end. Just a word of warning...it may not be the case for yours

Hey,

The actual immobilzer for the NATS system the JDM BNR34's are equipped with is inside the factory ecu, that's why they don't want you removing it. If you replace the ECU with something like a VIPEC you'll find you no longer need the coded key to be able to start your engine. The BNR34 Power FC supports the NATS system though, but doesn't need to be recoded to work with the NATS box, like the stock ECU does (if you replace it with another stock ecu it still won't work till you take it to a Nissan dealership and get it recoded).

On another note, you say you want a BNR34 Power FC.. I have one sitting right here out of my car with handunit I'm willing to let go relatively cheaply =)

Cheers,

Markus

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      By sonicii · Posted

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
