Thanks Duncan, I started the project in June 2021 so it took a while but also I did push it a bit and ended up being annoyed by the amount of work. But it's almost done 😄 Promised video 20221120_130131_1_1.mp4

Hey, just a quick update. I drove it over the weekend and it's mental! Loving the V8 sound and the torque 😆 Have had a problem with the MAF connection, I did not have the newer 6pin but the older 5pin MAF. There was a change in ECU connectors between 2004-2005 on the Infiniti M45 that I used as reference but Nissan Cima F50 never changed the ECU connector so both schematics confused me. Now the engine is running well but still showing P0113 so will do some measurements and check the live data to see what is wrong. Apart from that I had issues with VDC off and SLIP when turning, that ended up being the steering angle sensor that needed resetting. Nearing completion after a longer break from this project so hope I get it on the road soon! Will pop over a video later of the Skyline on the road. It's been a long project this one and lot's of stuff I have learned, mainly not to attempt something like this again! 😅 Way too much work to get it done alone.

More progress. I found a online filter cfm calculator, not sure on the math but the filter surface area calculation proved to be quite useful as well as the pointer from Duncan that the stock panel filter will allow 280bhp. To put some numbers into perspective: Stock panel filter is approximately 281x168mm which should be 472cm2. Got a proram cone filter 150mm diameter and 125mm height. That equates to 578cm2. So here is my intake solution for now. And also got all things sorted in the engine bay, just minor details with the electric fan control and that's it! Hope to start the engine this weekend, get it up to temperature and hope it won't leak any fluids If not I will have my first test run!!!

Standard throttle body but standard airbox from the V35. I only had a part of the stock intake duct that came with the Cima engine, connected to the TB with all those resonators and stuff. I ditched all of that cause it will not clear the strut turret. I am hoping to make a bit more power with the much much free-er flowing exhaust and 4-1 headers. Came across some intake filter calculator and it seems the V35 panel might be a bit too small. With the minimum space left in the engine bay my only option is a CAI style intake with a cone filter somewhere behind the bumper. Wonder if I need to worry about getting the filter wet? The CAI might give me better low-mid range torque as the duct would be quite long. At least that is how I understand the post TB duct working in that way. Short is better for top range. With the stock V35 airbox everything is a bit too tight and had to chop off a portion of the box as well. Might be too much of a bodge.. If anyone has any experience with n/a intakes or any pointers? Thanks!

Quick question or rather thoughts. I am about to connect the stock airbox with a standard panel filter to the TB. Luckily the throttle body outer diameter is the same as the MAF so no worries there. I have slight concerns that it will not flow enough, to be proven by measurement later. Just want to get the car running but it looks kind of silly with the short odd shape intake duct that I need there. Might look stock though Ideas?

Bit of update. Got a propshaft joiner made up in a machine shop to connect the shaft pipe to the new flange. Got the runout down to 0.3mm so quite happy with that. FSM specifies max of 0.6mm. Jig I made up to get it done: I will see if the prop vibrates at high speed cruising, if so I'll get it balanced. Changed the bearing and I expect the donut coupler will dampen some slight imbalance. Found a leak on my transmission sump so need to change the gasket but looks like I am almost there. Will post some more photos later this week.

Got it, so probably some heat shield to protect the floor then, thanks for the good info!

Thanks for the tip, but isn't the cat working properly when at correct temperature? Hence they are fitted as close to the engine as possible and come with heatshields from factory with some insulating fibre in between. Reason I want to wrap them is that they are way back from the stock position so to pass emissions testing. What I heard is that the cats will melt if running too lean which would mean very high EGT. I might see how it will do with emissions testing, if it may struggle then I will consider wrapping but could do some EGT measurement and see what temperatures will be present. I believe the honeycomb structure is ceramic with deposited rare metals on the surface so I can determine the melting point.

Some updates, finished the exhaust and fitted the dual fan assembly on the radiator (very snug fit!). Going to fit two extra o2 bungs for a wideband sensor and heat wrap the cats for emissions, if it helps. Now need to fix some tiny rust spots and finish up the suspension so I can test if it moves, well once I get my propshaft 😄

Haven't heard about the tesla screen tbh, but not a fan of big screens anyway. The TFT I have might be 7" actually but has touch as well so I can control the phone via the screen. I'll share more info about this later when I get it installed and working. Just wanted to share this option here as well.

Not sure if any of interest but I am in the process of re-fitting the original display for a 6.5" TFT with better resolution, remove all of the old nonsense and use a raspberry pi with "crankshaft OS". Then you can mirror your android phone over bluetooth or USB and use your phone satnav, play music etc. Fit's over the old display bezel but needs a custom PCB which I will work on later, need to finish my engine swap first 😃

Thanks for the info mate. To be honest I haven't delved much into that but the puny got even punier cause I went with a Nismo oil filter. NS4 or 15208-RN011. I only imagine the smaller one will need to be replaced sooner cause of the size, not worried about this at the moment. But that is what they recommend on the Cima F50 which my engine is from.

Well I unintentionally ended up in that "engine out" scheme. Depends which gasket 😄 but to put bluntly and oil replacement is doable without taking the engine out 😄 Seriously though, the engine is so tight in there that I struggle to remove the spark plugs on cylinder 7 and 8, no chance to remove exhaust manifolds without removing the engine. Let's say rocker cover gasket is also an engine out job but I have done that now. The engine has 42k km's so I do not intend or expect to do any maintenance except the usual stuff anytime in the near future. The Nissan V8's are awesome engines, very underrated. Must have been a hell of a job considering the Z has the same amount of engine bay room? I am finding that it is quite the task 😄 Got an oil cooler for the A/T. I am not too far away from getting everything ready and starting the engine!

Test fitted the radiator today just to see how much space I got available, not much... Also plan to fit the OEM dual fan assembly so it will be a super tight fit, had to push the radiator a bit more forward by cutting material from the composite front panel. Going to weld the water inlet so it is a bit lower. Next up is tidying up the wiring and vacuum lines, figure out how to make an airbox if I can find space for it! 😅
