What bits and pieces in the engine bay should I get powder coated based on my photo below?

Usually you only do it to pieces that show corrosion. More important than that is your radiator has no fan shroud which is going to be a problem if you ever get stuck in stop and go traffic.

Thank you for pointing this out. I’ve seen two different mechanics over the years who failed to mention this 😭

can this be fitted relatively easily? What tools will I need?

No way would you pull the inlet manifold off just to powdercoat it. You do that when the engine is out for work.

Are you planning on taking the car off the road for a month?

If you're incompetent like me and have a day job figure more like two months, pulling the intake manifold is a very involved job and it's likely that a lot of the rubber you touch isn't going to be reusable which adds a lot of waiting time as you order parts. I highly recommend using painter's tape and a sharpie to label every nut and bolt you pull. I also recommend after every major step that you take photos of the engine bay with a phone camera so you know the orientation of everything as it goes back together. The EPC part diagrams are good but no replacement for actually being able to tell what orientation a heater hose needs to be in, nor will it tell you what direction hose clamps should face so they don't grind into your intake manifold when you go to put it back on. I've also been keeping a journal of notes along the way, any little gotchas to look out for so you remember when you put it back together. It's a lot better than say a BMW S63/N63 engine but it's no walk in the park.

Part number is 21475-81T00, you will need some bolts and some foam strips to seal the gaps between the shroud and the radiator as seen here: https://nissan.epc-data.com/skyline/bcnr33/3935-rb26dett/engine/214/21475/

As for the actual installation I'm pretty sure you have to remove the fan from the fan clutch, pull it out of the engine, put the shroud around the fan, then lower the shroud + fan together back down into the engine and bolt the fan and shroud back in. I've never done it but I recall seeing people do it that way. I'm not sure your radiator is stock either, which might be why there's no shroud. Maybe a previous owner replaced the radiator, discovered it wouldn't bolt up/fit anymore and just tossed it.

Thank you for all that!

It's a cosmetic choice so up to your preference, but I get the cam covers, upper timing cover, twin intake pipe and plenum done. Couldn't find any good engine bay pics but they make it come up nice

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

      Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
