It doesn't look like there's a lot of options out there these days, and what's out there is performance oriented aftermarket stuff (with the GTR markup) I wonder if there are other cars with similar springs, after all its just a matter of length, diameter and stiffness. Alternatively, I did see coil spacers. Probably not the best option, but could be serviceable too.

I've noticed my rear springs sag a bit compared to the fronts. I have stock springs and KYB struts. The front wheels are pretty consistent in their ride height, but compared to the front wheels, one of the rears sits 20mm lower, and the other 40mm lower. This negatively affects the ground clearance, and also angles the headlights up. What are some some economical options for new springs? Or information like good spring rates, lengths in order to find a suitable replacement etc Far from lowering the car, I'd prefer to raise it a bit to keep it ground clearance friendly.

Realistically, an English translation hasn't happened in >25 years, but luckily you don't usually need to translate the whole billion page manual. I've used this tool before: https://www.i2ocr.com/pdf-ocr-japanese The manual has enough English headings and words to get to the section you need, then the OCR tool can help you decipher the remaining info on the page.

Give some thought to doing a big suspension and brake overhaul. I did that about 11 years ago and it totally changed the feel of the car. The steering was much sharper and the car tracked straight over bumps in the road, whereas before it was a wandering mess. It might take you a couple of months with the car on stands, but it's given me a decade of rewarding results. Given the age of the car, you could probably assume the following are stuffed: All suspension, subframe and steering rack bushes. I used Superpro polyurethane replacements. Inner tie rods and outer tie rod ends on the steering rack. All ball joints, 2x for each front wheel (on the lower control arm). Same as skyline GTR. Rear suspension has 1x ball joint. Certain suspension arms can be replaced with adjustable units, like the caster arm, and upper control arms for the front suspension. This allows the alignment to be set more accurately than those crappy eccentric bolts that are standard. Having everything stripped down is a good time to get to things like the driveshafts. While they are very good quality and long lasting, the boots inevitably crack and lead to the contamination and destruction of the inner joints. Over the past year and a bit I've replaced all 4x driveshaft boots (ie all 8x boots). This gives you a really solid base to then start piling on the mods.

Yep I soaked them in WD40 overnight and came back the next day with a mallet. They were indeed stuck due to corrosion, but came loose after a few minutes of hitting. It's definitely easier to do this with the hubs out. Also on the issue of presses, I have a 6 ton press which has been fine for every bush and bearing I've had to do over the years, including this job, but the downside is the platform is quite small, making it difficult to mount a full hub on them for pressing. I was just looking up a 20ton press for the wishlist.

They seem to be getting scarce on this side of the pond too! Mine is modded to what I would consider "Stock Plus", basically sharpened suspension, shift kit in the auto trans, slightly larger turbo and an ECU resulting in 200awkw. Gives it more pep without being too laggy, and also not on the brink of snapping something. Ive owned it for 15 years now, myself among others here can give you a fair few pointers on what should be done, and what shouldn't be done.

In relation to this video: A few things in here really made me facepalm. It uses belts to drive the cams and oil pump, which wouldn't be too remarkable except that they're INSIDE the engine, and while I would hope that they used a special composition belt, the state of the belts in a short service life leads me to think they're pretty much standard rubber timing belts that last about as good as you'd expect bathed in hot oil their whole life. In this teardown, the belts appear to have caused the destruction of the engine. Also, the timing belt isn't keyed to the crank. Yep, that's right, it only keeps timing if the toothed pulley remains torqued enough. I shouldn't be surprised that this exists, but I keep wondering why it exists. Even an amateur engineer can see these obvious failure points, and yet a company with more than a century of experience in motor design has made this engine. Some things might be easily explained by cost cutting. Not keying the crank technically saves on a machining step. But belts inside the engine? The more sinister side to all this is 1) planned obsolescence after about 5 years, and 2) difficulty in maintenance and repair by either the consumer or 3rd party repair. Take for example the timing belt, it's no longer a matter of simply synchronising the belts teeth to the correct teeth on each pulley. It now has an infinitely variable pulley which needs some special tools to get it synchronised. Does anyone have any insight into the industry? I can't believe these are ideas originating with engineers, but rather the accounting department. Or is that even too generous to all engineers, is there also a culture of amorality in which they're in the business of creating the ultimate disposable consooooomer item? Let's not forget VW's dieselgate, there's plenty of engineers willing to go along with some shady stuff.

How tightly should the bearing assembly be mounted in the hub? Judging by this thread it should come out with a basic puller, however I bent a 3 jaw puller trying to push the bearing out of the hub. I've had to remove the entire hub from the car, but it wont fit on my 6 ton press. Even then it looks extremely difficult to support the cast hub in order to apply force to the bearing. I'm struggling with ideas.

Just changed my water pump which was in there for around 14 years. Impeller was spotless, no perceptible play in the bearings but maybe the tiniest bit of moisture got past the seal. That's definitely a fair bit larger than a standard impeller though.

Here's the tool I came up with if anyone needs some ideas on making their own. This is using the scrap I had lying around, just happened to have an ideal sized piece of steel pipe. The "teeth" are bits of M12 threaded rod, (obviously unthreaded would be fine too), and spaced out at 120 degrees. Just got the bolt loosened by myself, tightening shouldn't be too much of a hassle now either.

Yep, just got the radiator out and I think I'll make a tool to hold the pulley. Forget taking the starter out LOL Funny that even the Nissan manual specifies a ring gear locking tool that requires taking the starter out. Feeling a little nervous about those M6 threaded holes. The puller that I have only comes with some imperial bolts and they're all like M10 or M12 equivalent in size.

I'll probably tackle this over the weekend. The manual says to remove the radiator, do you guys bother with that?

Thanks. I'll procrastinate on the whole thing for a little longer.

Just double checking how you're locking (and accessing) the flex plate with the engine+trans in the car? Is that using a screwdriver in a vent/breather port directly under the bell housing?

Pretty much as per title. I have to do a timing belt / water pump replacement so I'm trying to figure out the hurdles before I get to them. What are some ways of preventing the crank from turning while loosening or tightening the crank bolt with an auto gearbox? Maybe jamming something into the starter ring gear?
