So, the 3” silicone 90* turned up so I wasted no time in offering it up to double check how it’d sit.
The silicone sits flush around the pipe, with the coupler at the throttlebody using a tiny bit of flex in order to create a more natural bend. Nothing a decent clamp will secure.
After a bit of thinking, it needs to be extended around 1.5/2” to be on the safe side, nothing to complex. Once this was done I set about order 2x hose tail/barb fittings to get welded onto the hot side (pressure source for the boost solenoid) and one for the cold side (IACV source), as well as a 3/8NPT boss for the IAT Sensor.
The correct coupler turned up for the intake, as the snout on the compressor housing is 81mm, as opposed to the 76mm intake I have. Bit of an odd size, but its all sorted now.
That’s roughly how the intake will finally sit, but final positioning wont be confirmed until the hot side is all welded up and installed below it.
The next task I wanted to tackle was heat management surrounding the heater matrix hoses, purely because I didn’t have much faith the torn cardboard heat reflective material Nissan used, what with the downpipe sitting much closer than a stock turbo setup. So, first thing I did was to completely remove the Nissan stuff in order to re-protect the hoses;
(I trimmed the top hose for those that may notice. The aim here was to try and “pull” the hose up and away from the downpipe without trying to kink the hose.)
Unfortunately I forgot to take a picture of the heat sleeving I used, but I grabbed some heat reflective sleeving from Merlin Motorsport who are kinda local to me. You may just about notice it in the following pictures
Whilst I was at Melrin Motorsport, I grabbed some Nimbus GII Heat Shielding, which I’ve only heard good things about, even the chap at the counter was praising how effective the stuff is. I got this idea via 2 friends and kinda think it makes the how setup look more purposeful as well as more effective. Thanks to one of them, Diamondsink on here, I noticed he runs a fire extinguisher nozzle in the corner of the shielding, something I wouldn’t mind doing in the near future when I get round to installing a fire extinguisher setup.
The heat shielding is a god send to work with! I tried to get a nice fluent curve to make it look neat, whilst making sure it follows the areas its trying to protect. For example, you cannot see it in the pictures, but the bottom of the heat shielding near the firewall mimicks the downpipes shape to try and control where the heat is dispersed to

What with the turbo sitting fairly low to a conventional top mount setup, I was kind of worried about the brake line. So I made sure the heat shielding sat low enough to protect the brake line, as well as a bit of fire proof sleeve for good measure
At this point, I received the adjusted brake line back, as well as a custom clutch line Proline Motorsport made up for me. Both of which fitted perfectly!
(Apologies for the terrible pictures, but light conditions are terrible under the car, who’d have thought that
)
The issue with the Z33 box is that;
a) The slave sits on the opposite side, so a custom line is required
b) The gearbox sits fairly low, so I don’t exactly want the clutch line to be exposed should I run over a curb on track or something.
So here’s how it sat once installed;
Thankfully, the 90* bend ensures the line doesn’t hang down which im stoked about. After speaking to 2 friends who run an SR/Z33 setup they both run their clutch lines different ways.
One of them runs the clutch line to the front subframe then around, whilst the other follows the gearbox around the top. Neither of which aren’t exactly what I had in mind, as I wanted to make sure the hose was tucked out of the way as soon as possible, whilst keeping it away from the turbo/manifold & downpipe area. With this in mind, I noticed there were 2x M6 threads on the rear of the sump, which meant that I could just a P-clip there, so essentially following the gearbox around the bottom and straight up to the master cylinder. The biggest issue here was that I didn’t want the bolt to foul on the flywheel, but nothing a lil’ bit of common sense could sort out.
Hopefully this will make things a tad clearer;
So that’s me kind of up to date at the moment, ive got a few little bits turning up but im hoping tomorrow the intercooler pipes will be welded up and fit without any drama’s (*touch wood*). I ordered up 2x pair of brake pads earlier, with one pair I spec’d to try and keep up with the track demands and kind of match the front pad (Ferado DS2500’s up front), with the other pair being chosen for their initial bite for the hydro pair of Z32’s.
