I got a set of gtr doors at home, 32kg, they still have most of the bits inside. minus the outer interior skins/trims

you could easily get them down to 20 something by removing motors and adding winders or something and cutting a bit

you cant just say that you can do that. im not trying to sound like a prick but ive done all the cutting and shutting that was worth while and removed the window glass and motors and it doesnt add up to 12kg. i weighted it every step of the way and if i had a search im sure i could find the paper work for it and it goes no where near 12kg.

im all for people having a go at trying it but its like me saying cut 3 inches off each end of the chassis and youll save 100kg. ive never done it so i dont say it can be done especially when some one is asking for facts and figures from what people have had proven results from.

the proven results were written in the post above yours.

regardless of that it sounds like you have the light weight doors so some one should buy them.

im not trying to be a natzi i just get anoyed when people say it can be done because they heard from a friend of a friend that read it on the internet which was probably wrong to start with. i very rarely enter into topics like this unless ive done it because i had spreading hear say.

32kg is exact same is late model gtst doors (which i have)

ok one more question...

what years did the early doors end and the heavy doors start??

i just saw some 92' doors and found out they are the heavy f%^kers.

so what...light - 89-91 and heavy - 92-93??

Yew, i wasnt saying 20kg on the nose. but 20 something.. you'd be spending a bit on lexan and grinder discs.. (also i wasnt sure if i checked if they were side intrusion jobs too)

p.s. i didnt see your post either ;)

short answer: yes it can be done

watch some video-option where they do the SUPER-LAPS they have some impressive figures for their track r32

remove all your glass windows and replace with Lexen/Perspects

remove anything that isn't needed (air con, cd player + speakers, redo wiring harness, washer bottles), cut up the doors and any other panels which will not affect the strength/stiffness of the car.

also not sure if you can/allowed use aluminum parts (e.g from gtr guards and bonnet), fiberglass or carbon seats etc

just to clear up some stuff about the doors.

yes the early model R32 (both GTR and GTST) do not have side intrusion bars in them from the factory. HOWEVER most of the cars that have been imported would have had the intrusion bars fitted during compliance (which them makes them just as heavy give or take than the late model doors).

BUT, early model doors with aftermarket intrusion bars fitted CAN have the bars removed (they are usually riveted and welded in place).

the early doors are 89,90 and part of 91. late model intrusion bar doors start during 91 and of course run to 94.

the late model doors it's nearly impossible to remove the intrusion bar from. it's not really a bar at all. more of a giant plate of steel. and it's heavy as fark.

the only option really is importing a set of early model doors from japan (so you can be sure they haven't had intrusion bars added). i'd say about 80% of the early model cars in aus were complied properly and have had the aftermarket intrusion bars added to them.

to sum up:

if you have late model doors: forget about removing the intrusion bars.

if you have early model doors check if you have or don't have aftermarket bars in there. if you do have them they 'can' be removed but it's still not necessarily easy depending on which bar kit was used, and how they were installed.

you also need to consider the safety aspect. the intrusion bars were introduced for a reason. and they were retrofitted during compliance for a reason too. it's to stop you from getting turned into a vegetable if you are unfortunate enough to get t-boned. if you have an extensive cage that has side impact protection then it's not such a concern, but if you have no cage, or a basic cage without proper side intrusion protection then I personally would leave the bars where they are.

my 32 is a 89 model. it was registered in qld. has no intrusion bars in the doors. partly why i ran the cross brace on the driver side of the cage. I have seen some glass doors floating around, but the doors are light once you pull everything out of them.

there is considerable weight difference in the alluminium bonnet. it is a must.

remove all the bumper bar supports etc.

i removd the entire parcel tray and sheeted it with 0.9mm alluminium. same with door trims. no roof lining, glove box, dash cluster, nothing.

no power steer, no intercoolers, no wastegates, no turbos, no pipework, nothing.

no cast iron engine block lol......you get the picture.

1193kg

my gutted 32gtst weighs in at 1136kg full fluids etc

newer doors can have side intruisons removed by drilling spot welds & cutting intrusion in half 18kg weight loss just intrusion bars alone

i think the boys were refering to real race cars lol......no seriously Jas thats a great effort to get her that skinny. :P

Real race cars??? didnt you fit a commodore engine???

But also on a serious note the car has been built so it can be switched to circuit at any time

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
