you can't look at a group a car for weight numbers. Fristly they had a pretty basic cage compard to todays standards, and things like most of the suspention being custom milled from alloy, and use of lightweight materails everywhere.

The GMS cars were pretty robust; they were the 1180kg cars. Bolt in caged NME/Jap cars at the 1115kg end. Very little custom milled alloy suspension in the R31s though they did run cast mag front uprights and heavily modified standard arms in the rear and tube front LCAs (can buy plenty of that stuff off the shelf for R32) . When you consider they were also running additional coolers and pumps for the diff, box, turbo, engine oils, full steel panels, an enormous fuel cooled ECU unit, onboard extinguisher, dry sump and pump, big turbo on an enormous steel manifold etc it doesn't seem that unrealistic to me.

And shaving 180kg isn't all that much (assume cage is 60kg), not compared to 265kg.

I think it's doable without going crazy. Remember mine was weighed at Targa at 1275, with all our safety gear (suits helmets etc) and nearly full of fuel. We aren't trying too hard, the car still has everything under the dash, climate motors, heater box etc.

There's plenty of weight that could come out of it if I was to spend some more time doing it.

ahhhh, i read in other places you said it was 1280kg, and i assumed 1280kg curb.

i think keeping the fan and heaterbox is worth it for rallys, when your in the car for ages, and driving with the windows down can make the notes fly around.

haha... r33 whales... good one... glavin!

ive stripped a shitload out of my r32 already... alot which wont be going back in... im up to 60 something kgs with more to weigh yet.

ive got the list at home but off the top of my head:

a/c compressor - 11kgs

a/c bracket - 3kgs

a/c condensor - 5kgs

heater box - 3kgs

a/c evaporator - 3kgs

fan blower - 3kgs

stripping wiring - 13kgs

front seats - 19kg each (replacing with 5kg each race buckets)

rear seat - 7kg

p/s pump bracket - 2kg

s14 p/s pump - 2kg over standard

s14 p/s rack - 3kg over standard

hicas lines, valves, rack - 15kg

rear wing - 10kg

thats over 100kg there.. and ive got alot more to go. thats all i can remember, ill make a list and put it in my build thread. plus most cars these days have an aftermarket exhaust which can weigh 20kgs less than the stocker.. add to that a lighter straight through exhaust and a dump and front pipe. the cast dump weighs a few kg, as does the cast exhaust manifold.

ive still got front guards, bonnet to weigh over gtr items, inner doors to trim, boot lid to replace, power windows to remove, sound deadening and carpet to weigh, more wiring to sift through, reos to trim, alot more weight saving ideas to think about.. plus getting what weight is left more centralised...

but im not looking to comply with race or rally rules, or rego if it comes to it, just a fun track day car.

so i think... if you are looking to comply with rules, and are looking to compete in a form of racing with some degree of comfort... then no, you will struggle to get it to sub 1300kg let alone 1200kg

if you are a retard like i am and think its fun to have a pointless waste of money that is unbearable to drive the 5 times a year you are able to drive it then yes, you may even get it down to 1100kg... as is what im aiming for.

Sub 1300? Explain mine then, 1275, with fuel and crew gear? Mine is completely streetable and (mostly) legal, has Brembos/power windows etc so it's not by any stretch a stripped cop. Mine's a 12/89 model, am I right thinking they're a little lighter to begin with than later ones?

Fark me you guys make things hard...just run more boost!

not all of us can run dirty truck turbo's :ph34r:

Ben: the series 1 doors are 10kg lighter each, i just got some for my car.

hahaha i read that... and then didnt even realise what you'd said. my bad. i usually count the "crew" in... as some have 1 crew, some have 2 crew, and sometimes 1 crew can make up 2 crew, so if you have 2 x 1 crew that = 2 crew, that = 4 crew. :P

i know you said crew gear....i mean crew... as in crew people that wear the crew gear. haha.

it has to be taken into account when talking about weights... as when your using the weight that is the car and crew gear... theres an extra blob sitting in the rhs that can add anywhere from 60kg to 120kg. sometimes theres 2 blobs.

so your car is 1225 dry... 1280 wet... how much with you and your navigator slinging around corners??

this has got me keen to weigh my car, i have been meaning to do it since i finished it, i have removed everything mentioned and alot more, and am about 60kg lighter in the front end due to the donk, so im hoping 1100kg.

apparantly (meaning i actually have no idea) this bad boy does a 1:1.7 around tsukuba

weighs just over 1000kg, rb25 turbo on rb20, 310ps.

img20090829.jpg

there is more info around page 140ish in the r32 photography section.

i saw that in a option mag. from the little bit of english it runs a 1:01.xx, and is a RB20 with a 25 turbo. But I couldn't read a weight.

From the pics it's been extensivly stripped and speed holed, and those bolt in jap cages are light as.

Ok cool. I thought we were talking about fixed weights of the actual cars, as crew weight of course always vary. I'm around 90kg and Tim needs to go on a diet to offset me, he's about 70kg I think?

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
