NZ R33 Long Term Build

[R3N3]

Also, i think that the finned RB cam covers I purchased are not the genuine rb20 red top finned ones. I believe they are standard 20 covers that have been milled very slightly to create the raised fins… Im not sure if the guy I bought them off even knew, however, the fact they didn’t come with a matching valley cover is now a bit of a give away..

Anyway, annoying as it is, they are still a unique piece and they were modified very well, so I will get them painted up and put on the car. Now to chose the paint color…

I have been stuck into house renos every spare minute I’ve had lately, so the skyline has been neglected in the garage..

I have decided not to run the finned cam covers and sold them, I just wasn’t 100% happy with them. I also got scammed on FB market place, where I thought I had purchased a nice condition boot interior. So fair to say enthusiasm to work on the car has been low anyway..

it’s raining today and the kids are out of the house, so I thought I’d find some motivation and finish up the A/C install:

I gave the bonnet latch and bracket a paint black, as it was pretty ugly and so it’s less visible through the grill. The compressor is so much smaller and lighter than the old OEM unit. I also had to modify one of the AC hard lines, as it was fouling on the wastegate down-pipe. This isn’t a criticism of the FPG kit, as there is no way he could allow for every turbo/wastegate/exhaust combo out there.  I actually think it sits nicer this way now anyway, as the lines sit nice and parallel against the wheel arch.

I think the favourite purchase is the purchase of the bonnet prop/stay clip, as my car has never had one in my ownership..

Nice bit of kit, if that existed before I would have done the same.

AC is now all wired up. The fan switch and pressure switch are hooked up as inputs via the ECU and the compressor is an 8A HCO via the PDM. I’m assuming I need to set the pressure and fan switches as generic switches/inputs? And then have some conditions to switch the fan and compressor on/off?

engine bay all buttoned back up:

I ordered a TAARKS power steering pump AN10 fitting, as I’m thinking I’ll mount the power steering reservoir in the airbox, to tidy up the bay a bit more.

i have also noticed some brake fluid leaking around the reservoir of the BMC, so hopefully nothing serious. I’ll be flushing all the fluid and replacing when I do the rotors and pads.

in other news, I have booked a conference in Sapporo Japan at the end of August, so I have given myself three full days in Tokyo, so feel free to provide recommendations on where to go. The Nismo factory/showroom is top of the list so far.

The pressure switch should be inline with the + (I assume, or possibly the -) to the compressor. PDM can supply it power at all times when AC switch is on and throttle is less than say 80%, the pressure switch will just cut the circuit any time its threshold is reached.

At this stage I have wired so the pressure switch and fan switch are separate switched inputs in the ECU. I have then provided an 8A output direct to the compressor for switching.  However, I do like your way, as it would mean one less input needed.. maybe if I run out I’ll switch it.

are there any other conditions you would turn compressor off? Launch control active etc?

Here are the final dyno reports for each boost setting:

wastegate spring (7psi):

note that gate pressure sees the boost creep up to 12psi.

12 psi:

15psi:

20psi:

Went for a quick drive up and down the street after the tow truck dropped the car off and man it is nice. The sound of the turbo, exhaust, intake and BOV is just so nice! The power feels so linear in how its delivered. 

 

The turbo, is the rear housing .82?

I believe it’s the .63 housing
