You can make a sparco sprint 5 and I think a momo start fit without hammering the tunnel, but if you want the seat centered to the wheel you'll need to pound the tunnel. It's not difficult, just go to town with an 8lb sledge. I put cardboard overtop of the carpet and wailed away until it fit. No carpet damage, you wouldn't know it's been pounded out without actually inspecting it closely.

I've said it multiple times over the years in this thread, don't get Sprint V's if you want to daily the car. Find something more comfortable. They fit decently and are cheap, but that's all I can say for them.

Also it takes about 5-10 minutes to switch out a comfortable street-worthy seat for a racing seat on the occasional trackday.

Due to an administrative error I drove a car with a Sparco Sprint seat for several months (not quite daily as I don't drive to work, but it was my regular car). Literal pain in the rear end. The fact that it had no interior or rear seats made it rather noisy and very cold in winter, but the seat was the worst.

So the oil pressure gauge I ordered on eBay isn't coming cause the seller noticed that he doesn't actually has it anymore...
So I said gently caress it and rewound the coils on the original gauge. Took me the better part of my Friday evening (I'm just that kind of wild guy who spends his Friday evenings rewinding coils!)
Had a scary moment halfway through when the wire tore and I had to splice it together again but all in all it worked fine.
And surprisingly it actually worked! I know have a fully working, undampened OPG.
Holy poo poo though...that was a lot of wire!

I need to find an NB stock seat frame with the seat belt anchor on it, then I can switch between seats in <5 minutes.

Or... mount a seat belt anchor on the Sprint seat and use NA rails (that I conveniently have sitting) on that seat. :science:

That being said, moving the sliders between seats takes another 5 minutes on top of pulling the seat from the car, so... I should just suck it up, right?

I've always pulled the engine and transmission as an assembly. The only tip I can think of is remove the CAS before putting it back unless you're ready to dent up the firewall. The CAS hangs out just enough that it's not easy to slide back in, at least for me. Do the clutch, RMS and oil pan seals all at once. I've never seen oil pan seals that weren't ready to go at the same time as the RMS, they get hard and useless at about the same rate as the RMS, I find.

Probably unrelated but my 03s clutch shuddered like hell from when I bought it at 25K. I eventually found that revving up to 3k or so and really slipping the clutch would smooth it out for a few hundred miles. I believe there was a TSB for the problem on NBs.

I don't drive the car much anymore but it's at like 170k or so on the original clutch so I guess it didn't mind being abused too badly.

If you're just pulling the trans, make sure you have some swivel sockets to get to some of those bolts. The header ones I remember being kind of a pain in the dick. If you feel like wasting money, you can replace the looptie loop clutch line with a braided SS one.

I wouldn't touch the oil pan unless it's leaking (though I can't remember if you're technically supposed to take it off to replace the RMS). It's just one of those things that always seems to leak after removing it because I either A. didn't clean it well enough B. the silicone didn't set or C. I bent the gasket surface pulling it off, etc.

Nope, you can change the clutch and RMS without touching the oil pan seals. If you really don't want to pull the engine you can get away without it, but I've never had one (well, I only worked on 3, not a professional shop but my 100% data pushes me really hard) that wasn't ready to go at the same time as I pulled a transmission.

I just replaced the suspension on my NB sport, from the H&R springs (on the stock Bilsteins) to stock ones (on a different set of identical Bilsteins). I found the H&R ones to be way too low and stiff for my taste, last year I was scraping on bumps and stuff and the ride was really harsh. Good on track, but I average like 2 trackdays a year. So back to stock I go. After a test drive, it just handles bumps as gracefully as any regular car without making me cringe, which is nice.

Issue the first:
When I changed struts on my NA, I just removed the long bolts to the upper control arms, as taking balljoints out is often a pain in the rear end. Here though, while I could get the nut to it off, I still couldn't get the bolt off as it was seemingly stuck in the forward bushing. When prying on the bolt, it would not move inside the bushing at all and just spring back. When turning it as much as I could with a wrench it would just twist the bushing most of the way and only move a tiny bit. So I had to pull the balljoints which was just more hassle in many ways but worked out eventually.
Anyway, is there a trick to getting these long bolts to move? I sprayed some random lubricants on the bolt, but they didn't seem to get in far enough to do anything. I can't apply lots of fire as that would ruin the bushings.

Issue the next one:
The stock springs ride so much better. Small bumps don't send a jolt through the car, and large bumps won't make me fear for my life or chassis. Ride height went from 30-31cm to 36-ish. However, these might be just a tad too soft, and cosmetically I think it would look better somewhere in between in ride height. It has the ever present Miata body roll, and "kneels down" a lot under braking. I'm fine with this for now but might not be in the long run. Still I want to optimize primarily for feeling good on street (some mix of comfort and snappiness).
What would be a decent option for a spring that takes me maybe 1/3 of the way from stock to these H&R ones in stiffness, and lowers it about 2cm? I could of course get adjustable coilovers, but just springs probably would be better value for money given that I have an extra set of Bilstein shocks. Given how stiff the H&R springs are I guess the shocks I have are really too soft, but I would think they would be fine for just a relatively small change.

Comedy picture of 5cm forward rake when I had changed the rears but not the fronts:


Tragedy picture of a $10 balljoint separator that was made of the finest cast chinesium:


Issue C:
I have a very delightful 2DIN flip-front head unit. I think it was some kind of Mazda dealer option or something, as there was a Mazda logo on the German manual it came with (car was imported from Germany to Sweden in 2008) and it has no other brands/logos on it. However, the CD player in it is broken, the navigation is useless since the maps are on a CD (and cover Germany sometime before 2002), it has an aux input somewhere on the back but no plug/cable for it, and obviously does not have bluetooth. It is basically a very big radio, with a UI that looks like a web page from around the turn of the century. Maybe the cassette tape player works, but who the gently caress knows as I have no such tapes or means of recording any.
So I'm replacing it with some Chinese android thing (basically a very very thick Android tablet with an amplifier in it). But how the heck do I get this out? There is one tiny Philips (or maybe JIS) screw behind the flip-front, but it really does not look like it is what holds the thing in.

You might need a special tool to get it out. I tried my best DIYing it out of a coathanger and what not but it would always stick. Looks like this:

Yeah, I saw you could use those tools for the "normal" OEM head unit, but there you were supposed to pop off some bezel on the unit itself, and I don't have anything like that. I expect the resell value of this thing is approximately zero so if it comes down to it there will be destructive removal.

I'm getting this one ("Pumpkin" lol), which seemed to be the least lovely one of the various "brands". And of course, between the time I ordered it and now going to install it, they've come out with an updated version (more ram, newer android version).
I've only played around with it a bit (hooking it up to power and a couple of speakers on my desk), but it seems functional enough. Not sure how usable it is in-car though, with regards to user interface and such.

So, I was a bit mistaken. Turns out there are a couple of small plastic cover things on the side of the head unit that just snap off, revealing a bunch of holes. Still took the center console bezel off just to avoid damage to anything I care about. Looks thusly:




The three round holes I do not believe have anything of value, just seems like a void on the inside of the head unit. I had a pair of those removal hook things, they don't grab on to anything (and the distance between the holes don't match the tool at all). The two covering pieces were attached to here.
The smaller rectangular holes are just plain metal, nothing pokable there.

The slightly larger rectangular holes closer to the four corners seem like they do something though. I was poking and prying with various utensils and it feels like there's something there, but I can't figure out how to make anything unlatch or move. I can just get table knives stuck at odd angles.

Is this a Mazdaesque thing that anyone here knows about, or something more generic (in which case I'll gtfo and run over to the car audio thread)? Has anyone even seen this head unit before?

I don't see any obvious way to remove it, and lightly prying on it as much as I dare without knowing for sure doesn't make it move. Looking at the picture, it seems like the edge of the head unit is covering the top of it, which would suggest that's not the way to get at it.

I don't think I've ever fiddled with a car where anything other than maybe some bezel thing had to be removed to get the head unit out (apart from where it is completely integrated in the dashboard). Yanking on it, it sort of feels as if it is held in on the sides rather than top or bottom.

Oh I cant wait to get to the autox stage of my Miata.

I autox my WRX pretty regularly though. My tip is to not fumble with gears the first time out, more often than not it leads to slower turns even if you are bogging down low.

Empty as much stuff out of your car the night before. I've made the mistake of getting there and taking out a huge pile of poo poo. Take out your floor mats, spare tire, any stuff you keep in the car, extra removable trim, etc.

Bring food and lots of water/drinks. It's a whole day thing, treat it like you would an active day of working. Especially when it starts to warm up outside.

Talk to people. They know how to make times faster. There will be plenty of people with Miatas there that will know the right lines to take through corners. You might actually make some friends which is a nice bonus.

You'll want to check your air pressure before you run so bring a pump and gauge or be prepared to ask to borrow one. Tires are like 95% of the tech you need to focus on. They're everything. Bring some white shoe polish to mark the outside edge of the tread pattern. You want to use the whole tread pattern, but not any sidewall. The polish will rub away during your run and show you exactly where that termination point is. Lower pressure to increase tread usage, increase pressure to decrease it.

Oh god I've written too much. I really enjoy autox, guys.

This is true, until your region has a bunch of guys that go to nationals every year and have trophies to their name. Then car performance comes into play.

I wouldn't worry about shifting if you're just starting out. Just launch, shift into 2nd, and forget about the clutch until the stop box. Keep your eyes up, don't worry about hitting cones, have fun, and drink lots of water.

So, I managed to get that old head unit out at least without damaging the car. I was fiddling around with screwdrivers and pieces of hacksaw blades (with teeth ground down) and while I felt them getting caught on something, I was utterly unable to get anything to unlatch. So I went with the destructive approach; ripped the flip-front off and shredded the rest of the front panel, and managed to get to what was holding it in. With the front off I could unlatch them with the blades and get the sucker out, but even that was pretty tricky. The latches look like this when they're out:


You need some kind of tool that gets into the rectangular hole, and then up to that latch thing, and then push on that to bend it (which is pretty stiff), and avoid having it catch on the frame it's locked into (where there is less than a mm clearance). Never in a million years would have I been able to figure that out by just feeling around. I guess this is an attempt at making something harder to steal by requiring strange tools to do it. Four bits of piano wire or something would have done it though.

Since I do not expect a Mazda OEM head unit ever to be installed in this car again, I was going to just chop off the connector and splice a ISO pigtail on there (also a Mazda -> ISO adapter is too expensive either in money or time). But since I had destroyed the old head unit anyway, I figured I could extract the other part of the connector from that and do the wiring at my desk instead of out in the car. So I exploded the thing a bit more, and eventually won. Kept the brackets with the latches too, as I might just use them to mount the new head unit.

I do. But that would take a week or so, hence expensive in time. Can get it shipped quickly from within Sweden, but that's like €40. I could have ordered this thing long ago, but I wasn't quite sure what plug I would actually find back there (as I hadn't really researched the matter, it was pretty obvious though).
I wouldn't miss the OEM plug in the car had I chopped it off, I'd just rather do as much of the wiring job as possible indoors, so from that point of view it was worth the half an hour of effort to dismantle the old broken junk and unsolder the connector.

Looking at what pins have cables going to them in the plug, there might be signals for reverse gear (for backup camera) and parking brake (for annoying don't-do-this-while-driving warnings) and vehicle speed (for speed-dependent volume control). Need to check to see what's actually there, but that's at least somewhat useful. And as expected, no wires for rear speakers or steering wheel switches, because car doesn't have that.
