Knackered old Porsche with loads of miles - 996 content

It's 20 in a few months and I still think it's amazing that it is still capable of mixing it with new/current generation hot hatches, sports cars and GTs. I popped up to Caffeine Machine with a few friends yesterday and it kept the current generation of AMG and Golf R honest despite having about as simple an engine as there is these days in the back 
Let's be honest here; it's not exactly a 20 year old car with "as simple an engine as there is these days", is it?

I think it is really. The shell is all original, as is most of the gearbox (all of it bar diff actually), subframes and other structural bits are also original, interior is all as it left the factory, the engine castings are original as is the crank and the majority of ancillaries. Rear calipers are the old front ones and have been on the car for all of its mileage. The majority of parts replaced are what most would see as consumables. The engine is properly prehistoric compared to modern stuff. Port injection, no fully phased VVT, naturally aspirated, single throttle body, only per bank knock control etc. etc. compared to the clever stuff now like the turbo charged AMGs etc. it's a steam engine
I made up a mounting adaptor similar to what LN offer: https://lnengineering.com/boxster-and-996-motorspo...
The had Earls salvage the original hose ends and make up new lines to suit the install.

This is interesting. The gearbox in my 996 lunched itself and from what I learned afterwards they all start to whine and eventually implode. Is that right? Have you ever had your box apart or has it just had a new / different diff bolted on?poppopbangbang said:
It's also worth noting that Evans and similar coolants are flammable and despite the protests/FAQs they issue regarding this it will ignite if it is A) already hot and B) finds the exhaust manifold or turbo charger during high engine load conditions. There's already enough flammable stuff circulating around an IC engine without filling the largest capacity system in the car outside of the fuel tank/cell with stuff that will also burn
That is interesting...Correct me If Im wrong, Paul Walker's Carrera GT had waterless Coolant If i remember correctly? As far as I know many collectors in the states using that for their hyper cars, such as Veyron.
Surely his crash was a different story....

Thanks - LNE was the only solution I could find but I cannot stomach the cost!! - Particularly on top of the circa £700 for the Motorsport AOS.The had Earls salvage the original hose ends and make up new lines to suit the install.
If you ever market your mount let me know!

Mine started to whine at 150K'ish..... it still whines now. It depends why it is whining, if it is a pinion bearing failure and it whines on decel then this will eventually cause a failure. Mine whines due to the CWP clearances being on the large side, so it whines almost silently at steady state throttle. It's not always fatal basically. fastgerman said:

In your opinion, did everything need to be after market rather than oem replacements?
I also remember seeing an R32 for sale some years back with 200k Ish on the clock and not that old. Apparently it was a transporter car also - friend of yours? :-)
Not really it was more that it gave a good excuse to build new/better bits. You could just keep banging standard bits on and I'm pretty sure it would have got to the same mileage but been less interesting/fun on the way and had a lot more replacement parts. It is now a lot more capable than a standard one and I think a lot more reliable with it.In your opinion, did everything need to be after market rather than oem replacements?

If they were Mk5 R32s with fuel cells across the boot floor and a safe bolted to the rear seatbelt mounting points then yes we had a hand in that many years ago. They were used to transport precious stones from Antwerp to London and vice versa. At the time there was quite a few things doing this including more Golfs, Audi S4s etc.

Please take this with a pinch, as I've not run it, but the lower pressure would equal less stress on hoses, gaskets and other seals? The boiling point of it is said to be 180 Degrees Celsius, too. Preventing any further damage from vapour pockets should an overheat occur.
The Evans and any other similar waterless coolant is fine in old low output plodding stuff i.e. old farm machinery, iron block V8s etc. and is preferable as it will not lead to corrosion regardless of how long it is left but has no place in anything current/relatively modern. Yes it has a higher boiling point but its ability to actually move heat is way less than water whilst at the same time being more viscous, placing more load on the FEAD/Water pump and reducing mass flow through the coolant system. This is especially bad in cars with rads a long way from the engine, reverse stat setups and anything which is known to suffer from high component temperatures leading to scuffing etc. basically it's the worst stuff you could ever put in a Porsche and really running it in anything should be a VERY considered move including fully understanding flow changes that will take place by increasing the viscosity of the cooling fluid. There is still no real replacement for water as a go to cooling medium, it is still run in F1 today albeit in a pure form with some additions to reduce surface tension etc. because nothing performs better! It's also worth noting that Evans and similar coolants are flammable and despite the protests/FAQs they issue regarding this it will ignite if it is A) already hot and B) finds the exhaust manifold or turbo charger during high engine load conditions. There's already enough flammable stuff circulating around an IC engine without filling the largest capacity system in the car outside of the fuel tank/cell with stuff that will also burn
I don't use it, mainly because it's dreadfully expensive, and can't be topped off with water.

ETA. I never really understood the reasoning behind it apart from the fact it was handy for use in collecting gems of dubious provenance along the lines of conflict diamonds

Small world, I nearly bought that car, rear seats removed centrally mounted safe iirc

As I understood it at the time the prices between the two locations used to fluctuate quite a bit so if you were canny and could fill a next day order with precious stones from whichever location was currently booking them at a lower value there was a fair amount of wedge to be made.
