A lot of people mention the extra weight of the R34 and R33 over the R32.

How much real world difference does extra kilos make to the performance of a car? Obviously less weight means more speed and better handling.

So considering the R33 GTS-T is 3.7% heavier than the R32 GTS-T, would this mean that the R32 is exactly 3.7% faster than an R33? (obviously comparing cars with exactly the same tyres, suspension etc etc).

If this is the case, then 3.7% isn't much difference IMO - I think driver skill would 'outweigh' this small percentage when it comes to any type of competition, be it track or drag events!

Here are the KERBweights I've found for each model:

R32 GTS-T - 1320kg

R33 GTS-T - 1370kg

R34 GT-T - 1410kg

R32 GTR - 1480kg

R33 GTR - 1530kg

R34 GTR - 1540kg

What do you think?

slightly different wheelbase.. way the power is delivered to the ground due to the chasis design, weight balance, different gearbox ratios, engine toruqe, even aerodynamics, etc.

It's silly to say "R33 weighs <this>" as well, as s1 and s2 are usually different, etc, etc.. I know series1 R32 (89/90) is about 40kg lighter than series 2 (91-92)

Ok.. ill rephrase my initial question.. I just didnt want this to end up another series vs series thread!

How much difference does X amount of weight make in the REAL WORLD. People talk about the R33 as a 'boat' etc. But how much actual performance difference/benefit is there as a result - NOT including other factors of course.

Im not talking specific numbers, just your opinion of whether a small amount of weight makes a difference in the performance of a car

1989/90 R32GTST's weigh 1265 kgs, no sunroof, no ABS

For the same reasons 1989/90 R32GTR's weigh less than 1991/93 R32GTR's

Using engine power to weight is simplistic, you need to take into account the relative transmission losses.

Weight affects more than acceleration, there is also braking and cornering to be considered if you are looking at circuit work. There is also the effect of where the extra weight is. The extra ~200 kgs carried by a GTR is mostly on the front wheels, that has a big effect on how they handle.

Take a look at the success ballast applied to certain forms of racing, 40 kgs will take you from the front to the back of the grid.

:D cheers :D

My 1989 r32 gtst 4door auto,with sunroof and a full tank of gas in full street trim weighed 1390kg, so im guessing it would weigh about 1320-1330kg dry, anyone else weighed there car??

yeah im with primordial, y do they say that 33 is too heavy wen in fact a stronger engine helps out balance the weight. why call 33 a boat? wen the 34 is heavier?

I think people say that because of the way they look, rather than how they go.

You've also gotta remember it's not all about the total weight it's about where it is. For example if anyone here has driven an old porsche 911 you will know what it's like with that huge amount of weight sitting behind the rear axle. It's like a pendulum and when the rear steps out it's very hard to catch. It also makes the front end very flighty and not seem as grounded. Compare that to a porsche boxer with agrubly the best place for an engine (midship) and you'll understand.

So if a car weighs more also think about where it carry's it's weight.

    • Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes 
    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
