Yes, I have seen both of these videos, very informative! I almost want to try rebuilding these shocks without any nitrogen just to see if it will adversely affect its performance in any way. I, however have to be honest when I say that I seek to do it as correct as possible.
Too bad these shocks aren’t made anymore, makes it really hard to justify experimentation on.
An interesting read.
From my physical chemistry knowledge it could be that the shocks were simply assembled in an inert atmosphere e.g N2 glovebox as this would stop all the oil foaming etc… it also stops the oil reacting with O2 free radicals which causes changes In viscosity and ultimately oil to deteriorate in my day job we sell instruments that monitor this kind of thing to may oil companies. This would explain why the shocks don’t appear to be under any pressure even when new as well as the need for an N2 atmosphere.
Hi James
Welcome to the forum. That information makes absolute sense to me. The problem I have is that another person is showing evidence from the manufacturer that the strut is pressurised by liquid nitrogen to a very high pressure. I honestly believe that there is a mistake somewhere along the line and as much as I would love to finalise the video, I can’t risk giving unconfirmed information. I have a considerable amount of money tied up in strut parts so I can assure everyone that I will be doing what ever I can to get the answers that we need. I really appreciate your input and I think you are right with your suggestion.
I have been so hoping someone would find a way to rebuild these. Thank you.
When I finally go to turbo I will keep that in mind.
Maybe a shrader valve can be added and after the air is vacuumed liquid nitrogen can be added. As long as the disassembly of the old seal is done correctly and there is no leak afterwards. I have a 30000mile strut which the actuator has gone bad and after you press it down it lifts by about 15 cm.
Hello,
As I’m still waiting for an good solution to rebuild those worn front ECS shocks, I informed to buy some new rear ones for my VR4, but the are not available anymore @mitsubishi and other sellers like EE,so I had a go in Japan… I managed to get a pair of rear shocks for my car, pricey of course with import and shipping (price by private message only or my girlfriend would kill me 
) , but after waiting for 2 weeks, I received them today! Here are some pictures, you will notice that they are gas filled, and compressing them by hand is almost impossible. If someone wants to try it: part number I ordered was MB631665, changed to MB871463 (and replaced by MR179069), made by UNIASIA JECS Japan.
Are these ECS Rear Shocks? Do you have a direct link? Paddy
Please post more pics, especially of the ends!
Found them in the states and they seem to work on non turbo too!
Did you confirm that those rear struts are actually in stock? These online parts websites often have discontinued/out-of-stock parts still listed as available. You have to contact them to confirm availability, or go ahead and order the parts and be prepared for the order to be canceled if not available.
Most probably what you say is correct. Did not confirm.
I confirm these are original ECS rear shocks.
So here are some pictures of the top of the shocks I bought in Japan…
Greetings

How much was they? Interested
It was a lot 
I bought a lot more than only 2 shocks, but I recalculated the price with shipping and import taxes: 550eur for 1 piece, that’s about £490…
That’s some serious money. I have bought whole cars for less. Very sad
I am genuinely shocked about that price 
I knew they were pricey, but that much a piece… I really hope you get that investment back in 
Serious money yes of course, but I believe that’s the price for new genuine items that have become rare and for which no aftermarket parts exists, not to forget the huge shipping and import taxes cost.
Originally I bought 2 genuine shocks from Rob@EE (they were ‘in stock’) but after a while he admitted that they were not and he couldn’t get them for me (he asked 415eur a piece).
I can buy a 3000gt for a little money but I have never seen one with decent ecs shocks on it, and I don’t have to tell you that those shocks are very sophisticated, so used ones are always a gamble. I hope that we can get the front ones rebuilded in the near future as they ought to be, that would help us a lot and it would be a lot cheaper
Pascal
Is it possible to delete ecs and use shocks that are used in the mr’s or are they now hard to get as well?
Hi Spursman
If we are talking about AWD cars then the answer is Yes it is, you can buy a KYB shock absorber from the US that uses the ECS type Coil spring and the ECS Type top mount plate bump stop and Hardware from your ECS strut.
You can also fit the whole assembly from a MR (Shock, Spring, Bump stop, top mount Hardware) but the parts between ECS and Non ECS are NOT interchangeable.
I know this as I require two rear shocks for my SR (without ECS) and I imported two new KYB shocks from the USA (at vast expense) having researched through various forums, but unfortunately as can be the case the information on that particular forum was incorrect, the shaft size is different, the spring diameter is different and the holes in the top mount , the rubbers and the bump stops are all different, also the bump stop retaining system is also dissimilar.
So to Clarify the rear shock assemblies are interchangeable as a complete unit, IE: I could fit ECS shock assemblies on my SR but would obviously not be able to change the setting. equally someone with a car with ECS could fit complete rear shock assemblies from a MR but have no adjustment as the MR shocks are fixed damping.
Hope this helps, but if I have explained it poorly please don’t hesitate to ask any questions
