R32 Choices And Weight.

[raZ1911]

Hey there,

I'm thinking about getting a R32 skyline and put my RB30 that's being built into it rather than keeping my 180sx, as i want more even weight ratios.

But i was looking at www.imports.motortraders.net after i read some where that 1989 to 1991 skylines are lighter than the other ones.

May 1989 to 1991

Weight 1260kg

August 1991 to 1992

Weight 1320kg

So i was thinking;

What did they do to make it heaver?

Is there a way to make the newer models lighter?

If not would it be better to get a later model skyline as it would have better weight distribution up front with the RB30 and RB25 gearbox in it?

Thanks,

Andrew.

From what ive read, the series 2 r32 (1991-1993) had factory side intrusion bars installed into the doors.

Any series 1 r32 imported into australia, gets the bars fitted in during compliance, so in the end there is no weight differences.

The series 2 has different steering wheel design, different fabric, different colour dash fascia and different plastic interior (bumpy instead of smooth).

Plus other small little bits, but all these changes wouldnt affect greatly the overall weight of the car.

So side intrusion bars added 70kg?

good thread

what about the balance of the car, e.g. silvias balance is 48% of weight over front wheels and 62% over rears

so whats the balance with stock rb20

and balance with rb25 and or 30

cheers

im not sure what else could add weight to the car.

From my understanding, everything is pretty much exactly the same apart from some slight interior changes.

However perhaps someone would be able to shed some more information?

Might want to do your sums again, 48% + 62% = 110%

An s13 with any rb in the front(they all weigh pretty much the same) adds probably about 80kg to the front end, thats why you dont see too many s13rb26 race cars.

A mate of mine weight his skyline and its around 1250 and his is a 1990 so even when there imported here there still lighter than the newer models with the side intrusion bars.

So is it just the complete car that weights it because the way the chassis is made or is something added :S

Would it be better to go the older one then, as its lighter over the newer ones?

i have a late 1991 s2 and it not have intrusion bars

now with rb25 cooler 25 box lots of audio gear and my fat ass it weighed 1600 on the dumps weigh bridge

i do weigh 115 k

also had full tank petrol

[raZ1911]

wow you must have a lot of audio gear.

[raZ1911]

No one knows why the new ones are heavier?

Or if some one has weighed there newer R32 to see if its true?

[neo32]

i have massive sub box and 2 amps = 60kg

full tank petrol waht = 60kg

2b25det and box + 100kg?

25 l of old oil going to dump = 25 kg?

my fat ass = 110 kg

gtr wing lol = 10 kgbut yeah how accurate is dump weigh bridges

and u have coolent and oil and fuel to add on to your dry weight

and i have 18's and gtt breaks got to be some more weight there

cooler etc?

I don't mean to sound rude, but no one will be replying to this thread because it is completely useless! You're only talking about a matter of 60kg. I work for a manufacturer that updates each model constantly and has a face lift half way through a particular models run (new model every 7years so facelift usually after 4 years to improve the car and boost sales again). This is not a new concept and I'm struggling to understand why you cannot grasp it. A control unit can be superseeded up to 6 times in only one year. each time the supplier, casing, hardware, software (weight) can change with each item.

Your answer is simple but very long and boring = different composition of plastics, more sound deadening, different wiring looms, chassis strengthening down to the grade of metal used to make the car itself.

All these thing could easily make up 60kg.

Why do you care anyway? If you're going to put an RB30 in anyway, even a mildly warmed over example is going to pull a 32 along with ease. +there are many roads to travel to lighten a car if that is what you are concerned about.

(As said above) 48 + 62 = 110 and there is no way on earth that a silvia has a wieght distribution biased towards the rear! A S8 RX7 is one of the best weight distibuted cars to come from japan at 51/49%. why do you think all the serious time attack cars have the engine lowered and moved back towards the fire wall in a silvia? Let alone a skyline, which is heavily front weight biased due to cast blocks etc.

If you are trying to figure out which model to buy for your build than do some research on something a bit more poignant like which one will the RB30 slip into easier? With out ever looking into that myself, I would imagine a 1993 version that has or had an rb25de in it so all you need to do is swap the bottom end, fit the turbo gear and remap the standard ecu. Obviously it won't be that straight forward but it will go a long way to making things a lot easier.

i know this thread is f**ken old as, But if you (ellie) where not meaning to be rude then why the f**k talk down to the fella asking the question in the first place?, clearly he was curious and wanted some insight, just becuase you work in the field and "know it all" doesnt mean other people know and understand what happens and why. So to a person who doesnt know and wanted some insight be a lot f**king nicer you repugnant f**k!

[GTR_JOEY]

Fairly certain my 89 GTR doesn't have intrusion bars.. Doors feel far too light

So the chance of you seeing the somewhat pointless post/bump/whatever... Are highly unlikely. No need to post that, and certainly no need to swear your knackers off either. It's long since dead, next time leave it that way.
