A Silly Radiator & Gearbox Question

[Roy]

Can anyone tell me the weight of a 40mm aftermarket radiator, say from ARE, PWR or Race Radiator comlplete with coolant vs the std radiator complete with coolant???

I think im marginal for cooling with my new bar...so if the aftermarket jobbie will weight more then that will basically make up my mind

Also, does anyone know the respective weights of the RB20DET 5 spd, R32 GTR 5 spd and R33 GTS25t 5 spd?

[R31Nismoid]

it hardly weighs anything different.

the ally radiator from Race (same as mine) is very light.

Its holds a bit more, but then thats a couple KG's if your lucky

GTR 5-speed, more than RB25 5-speed (obviously)

Its a fair bit heavier.

One person can move the RB20 on thier own, normally takes 2 people for RB25 box, so fair difference

[Roy]

So whats your best guess if i cut off the transfer case etc and remove the associated gears and weld a plate over it...would it still be heavier then the R33 box???

I just dotn want to put weight into the old girl...

[R31Nismoid]

its the same box isnt it? just the case on the outside

[Roy]

Can i ask how much the cooler cost? Is it in the car yet? It wouldbe great if you could weight the thing for me. hell fill it up and weigh it would be even better

[R31Nismoid]

Its all outta the car man, has been and will be for a good 4-5 weeks yet

Mine was 2nd hand, new they are $660 inclu GST... i paid a fair portion less than that

rb20 gearbox = light as not a problem to lift (about same as a sr box)

rb25 gearbox = can be lifted by one person.. best for 2 people to do so as im 6ft n 110ish kg and i struggled to carry it a distance but how ever did so

gtr box = couldnt tell ya never had to lift one

Roy i weighed the RB25det box with shifter/fork and yoke before i installed it and it came to 61kg's on bathroom scales The RB20det box was 40kgs.

[R31Nismoid]

lol, and we all trust the trusty bathroom scales

even the stock rb20det radiator is very light without water in it.. I'd estimate about 3kg. It's not something where weight saving is going to be an issue.

just make sure you don't use heavy water in there or its all over

LOL...but my concern is at the moment my cooling is marginal. If a new radiator is going to be heavier then im happy to keep the car the way it is with the std radiator...but if there isnt going to be more weight then ill try and grab an alloy cooler in the next few weeks, will se how it all goes.

Ditto the gearbox, my current gearbox seems happy enough, but it is the most likely part on my car to break next so want to have a plan for when it dies...and no way i want to throw 20kgs at my car, if thats what the difference is...its not like i have big torque and 300rwkws which will kill the RB20 box.

Point is the difference should be pretty accurate even if the actual weight isnt.

[R31Nismoid]

more weight they get on em the worse they get... or accurate... now which was it

[dangerous_daveo]

Roy needs to loose weight?

[Ronin 09]

there's my alloy 40mm at Troy's - you can haul your lazy arse down there and fill it up and weigh it.

and R32GTR gearboxes are heavy... no, you can't have mine.

[ferni]

I just ordered an alloy radiator from race radiators, haven't got it yet tho... not sure if its the same size as one you'd get for your car tho Troy?

I could weigh it for you when i get it i guess

[TTT]

rb25 gearbox is 61kg and you panzy's can't pick it up?

[DCIEVE]

What is the point in the aftermarket radiator if it doesnt hold a greater capacity of coolant (and hence weigh more). It is a heat exchanger after all, greater the thermal capacity the better. This is assuming the difference in weight of the alum and plastics are neg.

The point i would think is not too have more weight or internal volume...but greater surface area does improve effeciency...and i would want one for improved effeciency/heat transfer.

Im just worried about putting too big a radiator in my car at great expense and additional weight...ignore the numbers biut an example is why have 5kw cooling capacity when i only need 2kws?

[dangerous_daveo]

How about ring PWR or something??? Surely they should have some specs?
