mmmmm, big mac.

a really good way do reduce weight in a Z is reaplace the doors with FRP type full shells, as they weigh a fair amount, also ally radiator, & less rubber seals as the seal kits weigh a bit.

and yes, loosing 10kg yoursel is like adding 5kw to the engine (more like 3 or so)

but where were we??

Ahh yes off to Mc Donalds for the Pounder. aka double double quarter pounder. mmmmm

nato (still about 80kg after 2 months in hospital & rehab, only lost 5kg)

So you mean a pounder??? Are we still talking about burgers??? :shock:

Speaking of alloy radiators, I should be getting a 4 core made up by a guy i know who is a master at alloy welding PWR cores soon.

Those fibreglass dashes might make a small difference as long as they are the right price. Might be cheaper for a salad diet. :D

Well I am 110 KG but I am also 6 foot 4 inches so even if I went on a dramatic diet I only stand to loose 10 Kg. I am aiming to shed about 50Kg from my 240z. I'm aiming to have it down to 1000KG with a cage and half a tank of fuel.

I just bought a VL starter. It weighs 3.4 Kg the original zed item weighs 5.8Kg so there is another 2.4 KG of my 50 KG target. :) Thanks for the tip Lurch.

Now I'm just wondering if there are more tips like that. What mechanical items can be replaced with more modern alternatives?

Also what is the wieght diference with an alloy radiator? Anybody weighed them?

The first thing I thought is whether it's worth the compromise of so little weight loss in regards to the reduced structural integrity of that section of the car

Just a quick one on the holes in the sheet metal.
The guy on Hybridz actually flared each hole, which means that he increased the stiffness of the standard sheet metal whilst still taking away weight.

whoo... $200/kg dam! There's lot's of places to save weight, aftermarket seats would be an option too

I was 6'3 at 13 and 85 KG. I was too thin. For someone else 85KG might be ok but for me my ideal weight is 100KG.

Does any one know the weight of a standard seat?

get rid of the gauges. they weigh a bit.

the ones u need get the lightest stuff i guess autometer as they got nothing in them.

if urs is the series 2 get rid of the toolboxes behind the front seats. prob save u 1/2 kg

other than than all the stuff under the dash like the heater box.

engine wise replace the complex linkages for throtle with cable. we not talkin kg but bit here and there should get it lower overall.

i think the window winder mechenism weigh a fair bit on the Z.probably fabricate bits out of alloy to replace it ie arms and sliders.

wiper motor mechanism. those motors weght a bit too. see if u can fit lighter ones from more modern car or replace it and use single arm style with manual switch motor bit like what they use on boats and old land rovers quite small motors.

windscreen rubbers weigh a bit. possibly urethane them in.

well thats what ill be looking at getting the Z on diet.

Got my standard seats in the hallway, but no scales. I don't think they are very heavy though, I would be guessing ~15kg. (I better go quantify that)

Bit hard to quantify, but definitely less than half of my 40kg jack.
I would say 10-15kg is in the ball park.

I guess that means if your going to put a race seat in (<5kg with rails) you can spend $1-1.5k (@$200/kg) on a seat. More then double that if you remove both seats.
