Hey dynamix, you'll need to clarify this further but i'm pretty sure you'll be able to use the standard RB25DET one because the main differences aren't going to be with the motor, they'll be to do with traction control etc. There shouldn't be a real lot of difference with the two motors and tuning of them so the standard power FC should run on that motor. Also if you're runing the standard loom then the standard PFC will plug straight in.

i'd say youd need an r34 power fc, but thats just my opinion. the neo6 has different timinig or something added over than standard rb25det which says to me u need a specific r34 powerfc, otherwise you could simply use an r33 stock ecu, which woudn't work im assuming, ask your local performance shop or ask who ever did the engine swap if you can contact them

its about the wiring loom actually.

I'd assume when they transplanted the engine, then also did the wiring loom to match it, unless the Neo6 has the same wiring as a R33 motor.

Be careful dude.

If you have a R34 ECU, then a PowerFC for a R34.

If you have a R33 ECU (which I don't think would work with a Neo6 cause they are slightly different) then get a R33 power FC.

afaik, the Neo engine has continuously variable valve timing, whereas the the R33 engine just has stepped adjustment. That would mean the R34 PFC would be the only way to go as the R33 PFC wouldn't know how to handle it.

You'd better check it up with a tuner though - I wouldn't want you to go and buy something based on what I said.

i've got the ROM reprogrammer for the NEC controller chip in the power FC. If you've already got a power FC I might be able to reflash it to the right one (will need to borrow a neo one too to get the dump of the software), and it should work, providing the ECU pinouts are still the same, and the only diff between the NEO PFC and the non NEO PFC is just the software on the PFC.

Or you could just buy a neo PFC and sell your current one :D

      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

      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

      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????

      Looking for autoelectrician in Perth who can do the OEM to double din stereo upgrade.

      Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
