Thanks for the advise but when it came time to take the crank bolt off the tools I immediately had next to me was a 21mm 1/2" socket, a 24" breaker bar and a rubber mallet. I combined them and the nut came off. The breaker bar also came off and went flying across the garage.

Unfortunately the fuel rail I got seems to be from a 2001+ not a 1999-2000 so the FPR interferes with the block. I'm trying to hunt out a 1999-2000 one but they aren't as common as the NA and 2001+ NB ones. I'll post some pictures of my disaster when I get home.

1991 NA; I recently started experiencing some serious stall out on startup and some heavy hesitation below 3k rpm. Usually after a few minutes it goes away.

I am guessing an O2 sensor. Any other things I should check?

Hot or cold restart? O2 doesn't quite fit, because closed loop doesn't take effect until operating temperature - and if it was trimmed high, it would run crappy when warm.

I'm thinking idle air temperature ... thingy. It's a valve that closes as it warms up, allowing extra air and higher idle while the coolant is cold. The easiest thing to do, is probably just reset your idle - which I'm not 100% sure if its different on the 91... http://www.miata.net/garage/ignition.html looks similar. Theres also a secondary valve on the throttle body on the 1.6's that keeps the throttle plate from snapping shut quickly, might wanna check that.

edit: also, as always, spark plugs and wires.

Phone is banned from exposing his timing belt in my garage.

Actually figured out what I need to get done on this car before it's drivable again.

1. Block off both ends of EGR (Yeah I know there is no power here but I'm not buying the parts I need to make it work)
2. Find a 99-00 fuel rail or hack up the 2001+ one to work with the NA FPR
3. Mount the coilpacks somewhere
4. Finish modifying plug wires to fit in the VVT valve cover
5. Find the intake cam angle sensor? or make a blockoff plate until I actually use the VVT
6. Remove the aircon from the body
7. Install clutch and mate trans to engine
8. Install GM IAT into my intake
9. Install engine/reassemble car
10. Adjust master cylinder and clutch pedal for the new clutch
11. Curse a lot
12. Wad it up at CMP

Does anyone know the name for the sensor that goes on the top of the valve cover over the rear of the intake cam? There are two protrusions on the cam that make me think a hall sensor goes there but Mazda doesn't show that part on their diagrams.

My MX5 has been reversed into, no note left, massive crack going down the middle of the front bumper.

It's a mk2 1.8. Whilst I'm going to be replacing it, is it worth going after market or upgrading the whole hog to a mk2.5 front end with the headlights as well?

These are some of my favourite mx5's appearance wise.

But I'm replacing the front bumper anyway, so a mk2.5 bumper and headlight conversion could be worth doing, or even going after market and getting something a bit more aggressive looking that allows cold air to get to an intercooler in case I ever go the Turbo route.

If you don't want to spend as much money as what Phone suggested (although you should), the next best bet is Ground Control sleeves, Koni Sport shocks, and FCM bumpstops.

If you're going to spend this much, drop a tiny bit more coin and get the FCMs, otherwise get the GC/Koni combo mentioned above.

It's basically a daily driver that I like to flog on the backroads when I have free time. I want better handling, and a suspension that's not literally dead from age. It has to be able to deal with really lovely roads without breaking, because Waukesha has it's road repair on the bicentennial plan.

so this is what I'm looking at? That's actually cheaper than I expected. I figured I'd be looking at 2k at least, so if I can get a full set of those with springs for 1500, that's pretty much perfect.

I would definitely recommend getting a set of Bilsteins or Koni Sports and a set of H&R race springs or similar high quality springs.

You will spend HALF of that FCM coilover package ($700-800 at shox.com) and it will still handle incredibly.

I have the H&R race springs, Bilstein sports and Racing Beat sways and I love them. Handles very nicely on the race track and is good for daily driving as well. When I'm beating Ford GT40s and Lambo LP640's around the track with basically a stock motor, it can't be that bad.

A setup like the FCM is complete overkill for a daily driver and weekend back road duty. It's more for someone who knows exactly what spring rates they want and is corner weighting the car.

I'm not joking when I say that there's literally 37 potholes between my apartment and school 10 minutes away. That's not even getting into areas where two sections of road are different heights and you just sort of crash into the raised lip of the higher bit of road as you go over it, or spots where railroad tracks are integrated into the road badly and are an inch above the concrete. It's crap.

aventari: where would you recommend to go to get the best price on those? This car, old as it is, will almost certainly never be tracked, so as long as it corners fairly flat and handles appreciably better than stock I'll be happy.

I think the 2011 Mazda2 understeers a lot less than the NC2 MX5. I just test drove both back-to-back, and it was a good time (tm).

The Mazda2 is super engaging, the 5-speed is nice, short and just like the NA/NB box. The important controls are in the right spot, brakes grab well, the steering is spot on, and the engine just moves you. It seems like a perfectly reasonable car to buy for commuting if you want something that is fun and engaging. It has no trouble getting up to speed and maintaining speed, but if you floor it in 3rd and expect to have something happen, you'll be sorely disappointed.

The NC2 MX5 drives just like the NA except when you mash on the throttle, you receive horsepowers and torques in return. The steering is better than the Mazda2, but just wiggling it on the road a bit, it seemed like the Mazda2 wasn't as floaty. There was a right hand 90 degree corner that the Mazda2 took at a pretty decent clip with only a smudge of understeer, but the MX5 was like LOLOLOLOL when I turned it in. I took it around the cloverleaf interchange a couple of times and I had to trail brake like mad in order to keep it planted. It was a sport model (or whatever else the base one is) with the 5 speed without the Torsen in the rear and no Bilstein shocks*, but either the shocks are poorly valved or the stock alignment is more than atrocious. It's still a fun car, though.

My theory is that the Mazda2 didn't understeer as much as the MX5 just because the power wasn't there, but it really blew me away with how much fun it was to just take out.

*NC Bilstein shocks: Apparently the factory Bilsteins are loving horrid and you get better results slapping some off-the-shelf Koni yellows.

Got the car fired up today and it idles well. Trying to figure out the last details so I can drive it again. Crossposting this from miata.net in case any one here has any better ideas.

quote:

I have a 2001 motor in a 1997 shell. I have everything connected except for the NBB coilpacks. I currently have the 1997 coilpacks plugged into the harness so I could get the motor fired up and make sure it worked well but that isn't a decent long term solution. I have a set of 2001 coilpacks for the motor but no good way to splice them into the 1997 harness.

I've tried to search for this issue but it's hard to get relevant results with any search terms I can think of. The best idea I have currently is to solder some leads onto the 2001 coilpacks and fill the existing plug hole with some kind of epoxy to keep it all weather sealed. Then splice the leads into the factory harness. Does anyone have a better idea or even better know a part number for the female end of the NBB coil plug?

destructo
Apr 29, 2006
If you're decent with soldering you could always just get quick release connectors for both ends and just cut/solder the plugs on.

Question: Does the front subframe brace bolt onto nuts that are soldered to the frame? I have a brace and two bolts, just curious if I need anything else at this point.

I feel about the same about the Mazda2, I really like it and my girlfriend likes it and I think she's gonna get a manual one for me to teach her on in February or so!

edit: I drove a Fiesta (auto and manual) the same day and it was slightly more comfortable, but felt a lot slower despite extra power and was really disconnected. The Fiesta mantran was pretty unpleasant compared to the 2.

The NC1 Bilsteins are awful, but I think the NC2's are better. The base shocks are bad too. I have the Bilsteins and I still haven't upgraded because of cares, but close to the end of this year I will fix all that. M.net says the NC gets pretty awesome with good shocks, so I'm excited.

Lookin' for a diagnosis.

1999 NB, 65k or so.

Within the past few days, whenever I'm going <10 mph or so, if I put the clutch in, I hear a high-pitched grinding noise. If I put it in gear and let the clutch out slowly, I hear a lower pitched grinding noise. The former is more like belt-squeaking than anything else, but it's not belts. The latter sounds like if you go touch-and-go on a wire-wheel, if that makes sense. Both noises are intermittent, but fairly frequent. They occur mostly when the car is cold, but the latter noise occurs pretty much all the time.

I'm thinking thrust bearing from cursory looks around google. Anyone want to back that up?

...and in that case, anybody in southern MA who wants to help a fellow do a clutch pretty soon?

I haven't driven an NC (as much as I love my NB, I won't be buying another Miata; cramming myself under a ragtop makes no sense for my 25-mile commute on a ruler-straight freeway) but I did drive a Mazda2 and came away truly impressed by its driving dynamics. I was sorely disappointed when I stood on the gas in third (first and second are fine) - I knew I would be, and it's not like it's scary slow, but you can definitely feel the ~40hp it's down on the NB. Remarkably similar curb weights between the two, especially given how much more room there is in the 2.

If they ever release some form of a hotted up version - be it a turbo on a 1.5 or 1.6, or even shoving a 2.0/2.3/2.5 in there, I'd probably trade the NB in on it tomorrow.

Shlomo: It's not more like a rattling? I've never heard a grinding sound out of my NB but ever since I bought it, it's been rattly as hell with the clutch out in neutral. That was 60k miles ago with no change in noise or behavior since.

George RR Fartin

No, it's most definitely more than rattling. It's like when you put a sander to wood, that sort of thing. No discernable loss of power, but the noise is disconcerting (and distracting). I just want to be sure I'm not like, driving someday only to have some part of the clutch just fall and get wedged someplace.

If you mean 'throwout bearing' and not thrust bearing I'd say yeah.
Try this: put the car in neutral with it running. Push the clutch in and out. If the noise happens when the clutch is in and goes away with it out, then it's the throwout bearing.

+1. I'm sure I could do my clutch with help, but I'm not sure I could even get it out without damaging something. I've done a pad/rotor job once and I could have done it alone, but it seemed mighty daunting to attempt without help.
