I didn't respond immediately, in the hope that someone actually knew a god answer, but seeing as no-one has responded yet....

I wouldn't hold out too much hope of there being a "kit" to rebuild one of these. Whether you can even get everything you need to fully rebuild one might even be hard to answer. I'm sure that you can likely get calves and rods and pistons and rings and bearings and the like. But sneaky little minor parts might be harder to track down.

Gawd. I just saw the typos in my post and nearly had a seizure, until I realised that calves is easy to mistype from valves.

Engine swap options are obvious. VQ35s of various sorts from later V cars and Z cars, and the same with VQ37. With or without turbo, depending on your willingness to go down that rabbit hole.

Honda K? Arguably a better motor, just sounds like shit.

Most parts would be available through suppliers like partsouq, amayama, nengun, Nissan themselves. Doubt you'll find a rebuild kit as such. There are some parts that are shared with other Nissan engine families. Things like bearings, valves, valve guides etc.

Partsouq/amayama will be your friend when it comes to part numbers and price.

Depends what needs to be done.
I'd personally go with VQ35 crank, cams and forged rods into a VQ25det, making it effectively a 2.8L with 8.8 compression.

There are no VQ25det "kits" that I am aware of although there is a mob (Takumi Autoworks) in the UK which are putting a kit together.

      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????

      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.
