I just put a set of R-SR front springs in my Nm35. After taking the old springs off the struts, I pushed down on the struts and was able to push them down every easily.

Not good huh. I put it all back on with the new springs. Pushed down on the front of the car and it sprung back at me like an expectant puppy.

How much for a new set of struts and what type, I see people talking about Bilsteins on this thread that's why I'm asking.

The very nicest non-coilover struts that you can choose to put in are Bilstein.  We usually use B6s, as being the best price/performance point, but B8s are a significant step up in niceness, if you can afford them.  These all work well with normal Kings/Tein/other good aftermarket stiffer springs in the stock format.

You can actually have them modified by adding adjustable spring perches to turn them into height adjustable coilovers that take normal coilover springs.  It's just more $$.

I got SydneyKid to build me a set of his Bilsteins......around 4 years ago now.  He was reluctantly still doing them for SAUers back then.  No idea if he still does now.  He puts a custom revalve into them that makes them even better than they are off the shelf (for Skylines).  He was doing similar for Stageas, but I have no idea if he did anything for newer Stageas.  Cost me ~$1400 for 4 modded dampers + new bump stops.  Vanilla B6s should be buyable for same-ish money, but I haven't looked.

I added new springs to my setup and ended up spending more than I would have for bottom end coilovers but somewhat less than I would have for upper end MCAs.  Seemed a good compromise at the time.

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
