The R34 GTR did get some attention, it got plenty of it. Under the spotlights, the Emtron livery popped, the Rajab Racing Intake and Pulsar G30-770 Turbo were on full show. It looked fantastic. I might be biased but I think it was the best Skyline there. Certainly the best R34 GTR. But, yes, I am biased. Very.

The car was dropped off the day before, and I arrived thanks to Ana around 10am, and had a great time looking at some of the spectacular looking cars there. Some are show queens, some, like mine, are street driven and well loved and others are somewhere in between.

I do love the differnet takes that people take on their cars. Seeing all different influences from Japanese, to euro, to American. The aggressive road car look really does it for me, but that’s not to say I’ll ignore the stanced look – it’s just not for me.

Thanks to everyone at The Ultimate Show for a great event, and maybe see you at the next one.

How was it? Mega. Honestly. The car is now so eager to go, it’s ridiculous. And smoother. So much smoother. The drive by wire is a revalation when it comes to the responses and driving of the car. On the move, it is just so eager to boost! It feels like it’s chomping at the bit all the time. It’s not scary, but it’s fun – and even though there’s not a huge increase in peak power at the top end, the extra 400-500rpm reducution in spool rpm makes it a much better road car. Read about that here.

What was the show like?

Well first of all, thanks to North West Mustangs, who had a spare space on their stand for me to jump on the end and get me in. But it started off wet, very wet. So, I sat in the car and watched Netflix for 30 mins until the worst of the wind and rain passed us by, then it brightened up and warmed up quite quickly, and we could get on with enjoying the show.

I WON!*

Well, I did, and I didn’t. I was awarded Best High Performance Car, but I had to leave before the awards were handed out, so the runner up was awarded the trophy in my absence. But the first real show of the year and I’ve got a first place, which makes the hours of research, the planning and orcehstrating of moving the car, fitting and mapping, the collecting, etc. It makes it all worth it. I’ll have to go back to Leyland Festival in 2025 to defend my title, which isn’t really mine!

So many people were so complementary about the look of the car, the less is more look. Some people like the gaudy look for attention, but it’s never really been my thing. I prefer the less-is-more look and let the car do the talking. The stickers from Stickers at Car Shows really help the car pop though. Thankfully the judges felt the same.

Engine wise, the car is done. I won’t be doing anything else to it. Externally, it goes for a front end respray in a couple of days. Interior will need a couple of panels replacing as they’re showing signs of wear and I want a steering wheel with some controls on it for the Emtron to take full advantage of it’s functionality. At the moment, we’re just locked into a single map until I decide which keypad and/or steering wheel suits me best…

• Rajab Racing Intake Manifold
• Emtron KV8 ECU
• Radium Fuel Hanger Nissan Skyline Late R33 & R34
• Nissan RB Twin Cam – Race Series CAM Trigger Kit
• Outsider Garage R34 DBW Pedal
• Bosch 74mm DBW
• Rework of the catch can
• Replacement breather hoses

I was kept completely in the loop as ever by both Lee (for the mechanical side) and Mike for the mapping side, and it’s turned out beautifully.

Rajab Racing Intake Manifold

Well, being the nerd I am, I like to have the car modernised where possible, and lets face, it safety is flexibility is key. And looking through the ECU logs, the amount of trimming that had to do be done when tuning on the ignition map on the stock intake was crazy. So to kill two birds with one stone, I decided to change the intake and go Drive By Wire.
The Rajab Manifold is doing exactly what it said it would. Better turbo response, more power through the whole rev range and no sacrificing of low end torque like the short runner manifolds. The Drive By Wire gives us more safety controls, better torque management and CRUISE CONTROL.
The downside is the cold side of the intercooler piping needed a reworking and the catch can piping. Not the end of the world, but it’s not plug and play like the Nismo – although it doesn’t profess to be, but it’s cheaper and better But is it worth it? Absolutely. And it looks sexy, doesn’t it!

Emtron KV8

After the removal of the Link G4+ ECU, the Emtron KV8 gave so many more options and flexibility to the car. It’s allowed the intake to be fitted with the DBW throttle, and to move the map away from the ITB/MAP merge to a true VE and Throttle Mass Flow, like how the modern OEM manufactuers calibrate their cars. Efficiency is key! ATESSA control will be dialled in at a later date…
I’ve now got so many strategies to play with, much better safety and CRUISE CONTROL! So when I go on my trips away, I can actually rest my leg for the journeys on the motorways/authobahns/etc. I’ll report more on this after more miles in the car. Read more here.

Radium Fuel Hanger

When the fuel pump was upgraded, we noticed that the fuel pump hangar was looking like a bit of a disaster, so we decided to upgrade it properly. The Radium Engineering fuel pump hanger replaces the entire factory fuel pump assembly inside the Nissan fuel tank. It can be configured with 1 or 2 fuel pumps, I just chose a single Walbro 400 for my needs, I can always upgrade at a later date should I need. The pump is suspended down in the bottom of the tank, similar to the stock fuel hanger. From there, they feed through polyamide nylon tubing to the top hat.

The factory Nissan fuel level sender and low fuel switch are reused so full functionality is retained. A venturi jet pump is integrated into the top plate and provides means to draw fuel from the opposite side of the fuel tank.

Race Series CAM Trigger Kit

Anyone who’s tuned an RB knows one thing: the OEM trigger system (CAS) is CRAP. It has issues at higher RPMs, the timing can drift due to belt stretch. After talking with Mike @ SRD, I went for PRP‘s Race kit, with a 36-2 Crank kit. It uses a MoTeC ‘reluctor’ type sensor and a MoTeC Camshaft ‘hall effect’ type sensor, a completely sealed sensor with external plug system.

This has been proven on many 1000bhp cars, so my 500whp affair won’t be a bother. The nerd in me like that it will provide 3 times more data than the 12-1 tooth system and infinitely more reliable than the OEM. It’s basically a Supra set up! Controversial statement…

Outsider Garage R34 DBW Pedal

The final part of the equation was the DBW pedal. I found lots of options for R32 and R33, but the guys at Outsider Garage came up trumps for me. They quickly checked against a car they had in the premises and reported first hand that it worked. So I ordered the bracket, pedal and loom. Perfect. If only everyone was that easy to deal with. Bolted in, with lots of wire to allow it to be wired in neatly to the Emtron.

The car is now right up there with the modern way I wanted it. Now, I have to think of what’s next for it.
Do I do more, or do I get a Supra and start a fresh journey… Tuning never stops!

This time, I wanted more of a hugging seat, wasn’t fussed on leather, just wanted some solid, comforable seats and my harnesses. So I spoke with Nick at Corbeau and we agreed on the RRB seats

As you can see, they complement the car amazingly well, and really keep you secured when making pace around the Scottish roads. Simply lovely.

I’ve done around 2500 miles in these seats now, involving drives to Scotland from Liverpool and from Liverpool to SRD Tuning in West Sussex and back, around 4-6 hours for each and I’ve never felt sore or stiff. They’re supremely comfortable.

Big thanks to Corbeau!
