What To Do Next?

[Corpsewalker]

Need to garner some input from the experienced owners and tuners over here. Been running my R33 GT-R for nearly six years, and have done quite a bit to it. To the point where further non-cosmetic mods are a topic I'd like some input for. The car is a pure UK fast road beast, no drag or track. It's a conceptual design by me with all specification, build and tuning by Abbey Motorsport.

Currently on the to do list are a Nismo plenum, Defi centre console cluster holding oil temp, oil pressure and water temp gauges, and a decent TPMS. Plus the full bodywork refurbishment when I crank up enough funds for the work.

To save duplication, here's the current full spec (apologies for daft length; project has got a bit out of hand ):

Nissan Skyline BCNR33 GT-R (Type 2) manufactured in April 1996. A JDM non V-Spec retailed through Osaka Nissan Prince in May/June 1996. Vehicle imported to the UK in 1997, remaining in original JDM spec without speedometer conversion until August 2002. Only the steering wheel & white dial sets were fitted in Japan.

Hello Kitty air freshener?

Love to see pics of your car man

When I finally get time off work i'm planning on replacing all the hoses and connectors in my engine bay, restoring or replacing the dash/interior trims and getting a full detail, + anything else to rejuvenate the condition of my r34.

[(OO)SKYLINE(OO)]

The list just goes on...

I think you have pretty much covered everything.

Is there a Supercharger waiting to be added?

While ya there, how about NOS LOL!

BTW you got any pics of this beast!

[Corpsewalker]

Photos: Hoping to get some decent ones in a few weeks. Car has either been off the road or the weather has been crap. My photographic skills are shite, so it's getting the time of a couple of friends who are camera capable and some decent weather. Plus a couple of bodywork blemishes dealt with.

Supercharger.... trust me, twin charging has been considered... very briefly. NOS? No. UK road law is funny about it (you can have it but you can't use it? WTF?) Plus it doesn't appeal to me.

Hello kitty air freshner? Hmmm, nice touch. Classier than those plane ol' pine trees or the blue plastic dolphins. But the pink just wouldn't work.

[(OO)SKYLINE(OO)]

I know you have considered twin turbos but add a supercharger on top of that... LOL! BTW it has been done before. Hehe!!

NOS yeah not much of a fan. Only in video games.

[POLICE]

All those upgrades - $xx,000

Trying to get yourself arrested and spend a night in jail? - priceless

[rev210]

got a carbon tail shaft or did I miss that in the list?

I must be obtuse today. Tried three times, still makes no sense. Do feel free to elucidate.

[Corpsewalker]

Nope, I have a one-piece steel prop instead. Still lighter than standard, still removes the coupling, but costs a quarter of the price.

[murf92]

shit! how much hav u spent on ur car so far???!!! gota get sum pics up man

murf

[r33cruiser]

i didnt see a surge tank on that list

[rev210]

Nope, I have a one-piece steel prop instead. Still lighter than standard, still removes the coupling, but costs a quarter of the price.

From what I understand the slight down side of a solid steel (or better chrome molly) single peice shaft is the transfer of harmonics and greater shock loading.

The carbon units in addition to being lighter as a little kinder to driveline components.

They are alot cheaper though.

[Corpsewalker]

Yeah, torque shock is a potential new fun area, but the rear diff was refreshed and toughened a few months ago.

Surge tank/plenum has been discounted as it would deliver no real improvement. It would be very pretty, but apart from that, a bragging rights modification only.

How much have I spent? Enough that I really should know better. Excluding maintenance, it's just under AUS$134,000 over the last six years (you did ask). But when I'm driving, the cost just does not matter. I could never get a car that matches my driving style, environment and reactions better.

To save a bit of time, here's the main rejects list:

Nismo rear diff has been tried and removed.

Crank damper is not an issue as I rarely exceed the 7200rpm harmonic threshold.

An uprated inlet plenum would not derive any real gains.

A pre-oiler serves no purpose for my style of driving.

High-beam harness rendered irrelevant by xenons.

Lower anti-roll bars irrelevant as I will not be doing trackwork.

Bigger turbos would have to be custom made, so the expense does not justify (yet). Likewise a sequential gearbox, or a significant upgrade in engine management.
