Can you elaborate what you mean with your first sentence? I meant move as in the bulge kinda seemed like it got pulled "outward" meaning it got pulled down and to the side with the jacking rail itself, so the load bearing bulge now sits lower than usual and is not level with the sill on the other side of the jack point. Either that or the jacking rail just got pushed in a good bit.

but any other area than the bulge you are talking about will just cave in then? The front driver side is pretty bent so I don't know if that will work the way it is now. I can still kinda make out where that bulge is/was but it looks like the position of it also changed due to all the mistreatment? Hard to tell

if need be I guess I will, yeah. Just to be clear, it's okay to use the sill area around the jacking points for loading, meaning the actual pinch weld or jacking point just sits in the slot without taking on any weight?

Fair point, but that can be mitigated if necessary. Or just making the reinforcement plating just in a certain smaller area located very far in the front. But it's just an idea.

Could not find the quickjack ones anywhere so far. The first link won't ship to my country and the second one is a fair suggestion but I'd like a square style rubber block with more surface. That narrows it down a lot too.

Yup someone was not careful. I also almost made the mistake to jack up the car using the chassis rails, but immediately stopped once I noticed what would happen if I kept going. Only made a bit of a dent (on already dented rails). For the reinforcement as I replied to GTSboy I mean something like this An actual steel plate or railing along the sill (picture is just an example)

Yeah not too happy about the condition of my jack points but I have seen much much worse on other photos. At least there is only one that is properly damaged, the others are not too bad. I was thinking this too and will definitely get on that, either sometime down the road or if I also fail inspection due to them being bent, but I don't think it's a big deal. Will find out once I have to do an inspection though.

thanks, figured it out though

I uploaded them with the "choose files" button. Is the resolution better if I copy paste? I think despite the somewhat damaged jacking points they are still not too far off the deep end. Don't want to fully destroy them. I can't find rubber blocks with deeper than 10mm grooves for the life of me. It's as if it was impossible to make thesee grooves 15-20mm deep. I'd like to avoid using the chassis rails. (BTW the service manual for some reason actually calls these sidemembers) As for the reinforcement of the sill. I was thinking more like a steel plate long the length of the sill or at least like 20-30cm long at where the jack point is. Width being the entire sill, so lots of surface area and a very usable stable point to lift and jack the car.

Fk me, I guess next time I will try to use the onsite attachments feature. I find it hard to work with so far though because I can't move the images to where I want them to be. I will try to make a separate post with just images. As for lifting. The work I need to do for now involves the exhaust and engine mainly, so the arm covering the jacking points is not a problem. But I don't want to bend in the whole sill or underfloor by lifting the car at the original jack points. I found some rubber blocks, 125 by 125 with a 10mm wide and 10mm deep cutout, which I'm hoping will work for not hitting the jacking rail. The sidemember, as seen in the service manual, are the rectangular frame rails that come from the front of the car and go alongside the gearbox and downpipe. Those that get crushed inwards if you use them for a floorjack. They are already slightly bent in from being used to hoist by other people. I think cutting off the jacking points and welding or bolting on a reinforcement plate along the sill might not be a dumb idea. Or is it dumb? A 2 post hoist is what I'm gonna work with, but not for any underbody work, just leaky engine and exhaust work so far. Depends on what else I find that might need immediate attention. For metalwork on the sills I think I'd just bring the car to a panel beater. What's your take on getting rid of the original jacking rails and putting reinforcement plates along the sills?

Yeah titanium always looks cool but I don't need that, just regular pipes would be fine. But I am really struggling to find any full hardpipe kit that is still for sale.

Hi all. I am aware there is lots of discussions about jacking points, where to lift the car and what not. But as usual just a lot of "in my opinion" and nothing definitive, and everyone does it in a different way. I want to hear from some experienced people on which points on the car it's okay/safe/recommended to lift the car using a four point hoist/lift. I will attach some images of my underbody. Sills are largely okayish, the driver side jacking point is pretty mangled though and it looks like the underfloor is slightly pushed in too, but I might be wrong. In the German Skyline forum, the consensus is to use the sidemember chassis rails in the front and the rear subframe? bushing in the rear. I know the manual says to never use the sidemember for loading but lots of folk do it and it was definitely done on my car too as they are slightly bent too. Based on the images, what points do I use to not make the already present damage worse? I'd use wood or rubber blocks to spread the load across a bigger area of course.

Hi, just checking. Did you get this stuff made by Vspec Performance and at what price roughly? Looking into (sometime later) also getting such a intake kit, and Trust as well as HKS don't make a full set like this anymore.

Alright, fair enough. Expected as much. Possibly, yes. However the kit is apparently not including every single hose and it is out of stock too.

So bending them yourself isn't feasible?

I am a fan of braided dash lines because they are so versatile and often better than alternative solutions. I do agree though that the OEM hardlines are not bad, but the hardline to rubber connections are the first point of failure. Converting EVERYTHING to dash lines would probably be way more work than it's worth, but I think if my power steering ever leaks that will definitely go to dash lines. Or to a different power steering kit. Unfortunately the turbo oil feed already is braided lines, I think the previous owner broke the original lines when they took the turbos off.

The problem with quality is that everyone says they have it but you have to find that out yourself. Changing all hoses only for them to leak prematurely would suck.

I saw on Amayama most of the rubber hoses are actually available and mostly very inexpensive, but I don't think I can get every single one. Is it possible to make these hoses myself?

Who made the hoses you used?

Can you enlighten me on your best practice regarding these hoses? I don't wanna make the same mistake if you already got a better solution.

I have some silicon hoses already, for example engine to watercooler. But yeah, I get the sentiment. The lower intercooler silicon hose is drippy too, despite not being very old. Does anyone except Nismo make these same lines out of rubber? Long term I think they'd be the better replacement, especially since the car won't live as hard a life anymore as in the past nor be driven as often.

I know most issues are just age related. But for example the turbo oil drains, there is dash adapters for these and you can just make a braided teflon line for them and (probably) never have them leak again. Also not terribly expensive. Can you even get the factory hardlines from new? Or are they repairable if they break?

I know it'd be much much easier with the tool. I hope I can find one that won't take 3 weeks to get to me an isn't a "Asian models kit" that has tons of (to me) useless adapters for a load of cash. It's a summer project/fun car. I do wanna enjoy it, without endless downtime over and over. So yeah I would even go and buy an engine crane + stand to save myself the trouble of hard to reach or unreachable places going bad later on. Would also be a good opportunity to put on a Fluidamper, renew the mains seals and stuff like that. I have some money on the side that I can use for that, what I wouldn't want to or be able to do is let everything be done by a shop or have my engine completely rebuild right now. I intend to do most of the "doable" jobs myself. Pulling an engine can't be that hard, can it?

Yeah I'll do what I can without taking off any major parts for now. If it becomes clear I won't get far with the engine in the car I'll have to think about the next steps. I am not too stuck on keeping everything 100% OEM, if there is better solutions, like converting most lines to braided with AN adapters, I'd rather do that than buy overpriced new "shit" parts.
