R33 GT-R Update: Nismo 320km/h Speedometer Installed

 

Being an old car, the factory R33 GT-R speedometer needed replacing. There were certain tell-tale signs - some of the gauges weren't really all that accurate (the water temp needle for example) and the backlight wasn't as bright as it used to be or should be.

 Nismo to the rescue

Seeing as the car is now capable of reaching higher levels of speed (thanks to the newly rebuilt forged engine), it was time to install Nismo's version of the GT-R speedometer. The reasons being that the max speed limit on the Nismo unit is not stuck at a boring Japanese 180km/h and the rev counter goes all the way up to a whopping 11,000 rpms. Now I'm not sure if I'll abuse the car and push it to those limits, but at least the speed needle won't be bouncing off the 180km/h marker anymore.

And last but not least... When the sun goes down and your sitting in the dark - you turn the ignition key and flick on the headlight switch - at that very moment, you just can't help but feel a sense of satisfaction and pride. It's almost like driving a brand new car, which is true to a certain extent.

Big shoutout to Miguel from NeweraParts.com for helping me with this upgrade.

Project Time Attack: Nissan S13 Coupe

 

In my previous blog post, I spoke of finding the right car to be turned into a time attack machine. After much deliberation and looking at several makes and models, I've narrowed the field down to one car and thats a 1990 Nissan S13 Silvia Coupe. 

My decision to go with a S-Chassis is primarily down to six factors, some of which were mentioned in the previous posting but will be further extrapolated here: 

• Good, affordable rear-wheel drive base to build up from

Front-engine, rear-wheel drive (FR) cars have a natural tendency to oversteer. Controlled oversteers can technically help you set faster track times but can be very difficult to control.This naturally happens as the rear wheels are used for acceleration, while the front wheels steer the car. Rear wheel drive (RWD) cars tend to balance towards 'oversteer' which sees the front of the car pulling to the inside of the corner (whilst the rear comes out). As some of you might well know from seeing drifters work their magic, some opposite lock, combined with acceleration, can help nip this problem in the butt. Therefore, if given sufficient grip, RWD is near perfect for track  - proof of this being that every major motorsport event in the world uses the FR layout. Even current most popular all-wheel drive (AWD) car in the world today, the Nissan R35 GT-R, has dropped its AWD system in favour of a FR setup, as Nissan seeks to dominate proceedings in the Super GT series. 

• Easy to get power out of the Nissan SR20DET engine

The SR20DET is a highly tuneable engine and its popularity is based on the motor's ability to produce power on the cheap. Also, the SR20's all alloy block, alloy heads, twincams, 16 valves and an intercooled T28 turbo, indicates that the engine possessed technology that was ahead of its time. This makes it a good engine to use in amateur motorsports.

• Option to retro-fit parts from other Nissan models

Something I've learned and come to appreciate after months of GT-R ownership is that, Nissan parts are highly interchangeable. Not only does this feature exist between cars that belong to the same family tree but also with other Nissan cars that were made on a different production line. This is also inter-generational feature - S13 can for example, make use of newer parts that were a standard feature on later model Silvias like the S14 and S15. 

• Massive amount of aftermarket parts

Testament to the popularity and longevity of the SR20DET, the engine enjoys tremendous aftermarket support and is fully backed by all major Japanese tuning houses. Even till present day, its easy to procure new aftermarket parts for an S13, as these items are still in production.

• Huge supply of halfcuts and spare parts that are already in Malaysia

This has to do with the fact that the SR20 was used to power many of Nissan's cars since the early 1990s. Hence, a large supply of halfcuts and parts have made their way onto Malaysian shores. Production numbers of the S13 alone, is staggering - some 251,410 units were built from 1989 to 1998.

• Proven track platform

Furthermore, the track capabilities of the S13 Coupe have been amply showcased at Sepang by Yoong (Ee Yoong Chern) and his HKS Garage R Hiper S13. The car lapped a best time of 2.26:5 at last year's Time to Attack Sepang and was ranked 4th overall. I got to know of Yoong through the Malaysian Skyline fraternity as he owns a R33 GT-R as well. You should see him drive it up Ulu Yam.

These following pics were taken prior to delivery of the car. I purchased the vehicle for a song and it came equipped with some goodies (widebody kit / S15 five lug conversion / R32 GT-R brakes / half cage though). The body is also very straight.

The S13 is currently undergoing a major make over - all of its consumables have been a changed, a JIC adjustable suspension installed, a new S14 gearbox bolted in, a Nismo GT LSD for the rear and lastly, 17" Work +5 offset rims with new tyres to help it steer better. I'm hoping it'll be ready for this weekend, so I could join a jaunt up Gohtong Jaya with the Italia Auto boys.

Ignore the drift, ricey bits. Those will be rectified in due time and a 2.2 stroker kit + Haltech ECU + cams + disco potato will be going into that SR20DET:

Spare Engine Rebuild Update: Installation

Its been awhile since my last post but never fear, the car is in the final phase of the rebuild. The RB26 block that originally came with the car has been taken out, allowing for the engine bay to be resprayed and the rebuilt engine installed, along with a few new goodies.

Spare Engine Rebuild Update - Tomei Forged H-Beam Conrods

Apologies for the lack of updates but its been a busy month for me and I've been waiting on a particular part to arrive. In fact, its the last piece of the engine rebuild jigsaw puzzle. I'm referring to conrods as it was the only other forged item that I wanted for this rebuild. Lo and behold the official spiel (summary courtesy of Nengun):

Usually, to give con-rod buckling strength and light weight character at the same time, H-beam or I-beam profile is applied. Tomei have applied a H-beam profile for the connecting rod for NISSAN RB, SR, CA, VG engines and succeeded in gaining high buckling strength while reducing the weight. Tomei produces con-rod's using a forging mold with the main bearing hole in its large end, so the 'metal flow' runs along con-rod's entire body. And with a use of special materials, they have succeeded in producing con-rods with extreme intensity and durability. 

Naturally, I got standard RB26 stroke conrods as I'm not stroking the spare engine. Thanks to my good friend Glenn Trollope of Chasers Motorworks Melbourne (good luck at the World Time Attack dude!), I was able to source the conrods in record time.

So that ends this update as the crank is being balanced but I'm hoping the engine will be ready before the end of May. Theres also the Nismo bearings that need to be installed and those had arrived sometime last month, courtesy of a fellow Skyline owner (thanks Nain!). 

Here are the bearings:

Can't wait for all the parts to come together. Watch this space.

Installed: Blitz Nur Spec R Exhaust

I've been looking around for a replacement exhaust in the lead up to my engine rebuild. My old exhaust system is a workshop amalgamation of a Kakimoto muffler and a custom straight pipe with numerous weld points. So it had to be factory crafted, loud and net a power gain. 

I was looking at titanium systems but not really sold on the sound - I prefer the more bassy note of stainless steel systems. Its also difficult to get a titanium exhaust repaired if anything were to break or crack, as we do not have a titanium welding facility here in Malaysia (or one thats accessible to the general public). Despite what some people say, you can't do a weld on titanium pieces unless its in a controlled environment, devoid of oxgyen i.e. a vacuum-controlled chamber!

So my search continued but time and time again, I came to the same conclusion. The Blitz Nur Spec R exhaust system came up tops among most Skyline owners in their forum discussions. The system also comes with a detachable silencer thats nests inside the muffler. So if there ever came a time to tone down the decibels (i.e. MOT tests), one can turn to this device (refer to the pic below - its the object next to the gasket and screws). The Nur Spec R is also one of the few exhaust systems thats completely made from 100% stainless steel - tip to tip.

So I ordered a brand new set from neweraparts a month ago and the exhaust arrived in Malaysia two weeks ago (80mm at the midpipe, 115mm at the exhaust tip). I also specified for a Zacetec Decat Pipe, which is required to replace the catalytic converter section of the system. This too came in the air freight box from Japan. Big up to Miguel from neweraparts for making all the items fit in a EMS shipment box - otherwise, I'd have to go with another Japanese air freight company and pay more. 

And so without further ado, here are pictures of the unwrapping and installation:

The package was long and huge!

Got a bit excited seeing the Blitz emblem

Factory packaging and bracing to ensure the exhaust is not damaged during transit

Getting ready to install the mid pipe

Wonder what lies beneath all that cardboard and plastic?

Isn't she a beauty?

I have to say that I chose well. The exhaust sounds amazing and loud enough to satisfy my inner boy racer fantasies. By removing the silencer, the exhaust is pushing out sounds above 100 decibels. And thanks to the small center cannister, there's absolutely no in-cabin droning, even at high speeds. Very satisfied with Blitz Nur Spec R and I hope to record the sound it makes, sometime this weekend - hopefully on a drive up to Ulu Yam with the boys.

Update: Series III R33 GT-R Front Bumper Installed

Per my previous entry, where I told the story of how I came across a R33 GT-R Series III bumper and set about restoring it ... well, heres the end result :).

 From this...

 ... to this! 

Loving the Nismo air ducts, the enlarged intercooler opening, the integrated fog light indicators and the bigger lower front air diffusers!

Found a Series III R33 GT-R Front Bumper

Now as I had disclosed in an earlier blog entry, my R33 GT-R is actually a Series II BCNR33. Hence, the bumper looks like this:

Its a very clean look and I like it, but I thought I should try getting a hold of a Series III bumper. The reason being that I had upgraded my Series II headlights to the xenons from the last model of the BCNR33 series. The Series III looks like this and yes, I just bought it today thanks to a tip off from some fellow Skyline owners (Jahax, Temujin and geber - thanks again boys!):

Just a bit of background on the car that this bumper came from. According to the rear bonnet section, the car was a late model V-Spec edition BCNR33. The tell tale paint chips of the front bumper indicate that the car was originally Awesome Blue or Aqua Blue and not Midnight Purple. However, it could just be that the previous owner had swapped in a new bumper that was originally painted blue (heck, it could have been painted in R34 Bayside Blue even). Whatever the case, one can't help but wonder what the car was like before its demise.

Notice the Nismo air ducts right in the middle? Another major difference between the Series II and Series III bumpers is that the intercooler airduct has a slightly larger opening.

First thing I did after purchasing the said item was to rush over to my painter and have him start work on restoring the bumper. It needs some minor restoration in the bottom skirt section as well as the sides. Once he has done doing that, the bumper will be colour coded to suit my car and we'll pop it on. Can't wait! Quite pleased with the purchase as the bumper came with the indicator lights, as you can see below.
