If you're building a 1.8 without a VVT head at this point, you're a fool.

Speaking of turbos, is there a setup that is CARB-legal, apart from FM II?

for the people saying it's not worth it to modify the motor unless you go with turbo/super: I'm really happy with what a $100 Raceland header, a $100 ebay muffler, and cutting up the airbox did for my 99. It makes revving it out a lot more fun, I gained noticeable top end. Of course the header does remove 1 cat.

Guys... something up with my NA. When I put it in gear at a stoplight, the revs drop by 200-300. Obviously the clutch isn't disengaging completely. Is this something I should adjust, or do I need to bleed my clutch lines, or am I looking at a bad master/slave? I don't think it gets worse as I hold it in.....

Probably bad master or slave. They're both cheap and easy to do, just do both so you only have to bleed it once.

I would check the slave first. Pretty common failure with miatas. I've never had problems with a master cylinder going, but it does happen as well. I wouldn't bother replacing the master at the same time if it isn't leaking, but that's just me.

Though I have a slow leak and still haven't done either of mine (I have to fill up the reservoir about every 1.5 months). I'm just lazy  Maybe add it to my list of winter projects that I won't do.

Like the slave, it's available dirt cheap at Autozone with a lifetime warranty...so if I ever replace them on my '99 again, they're both coming off and getting exchanged.

FatCow posted:Too lazy to rehost If you can't be bothered enough to rehost an image I can't see at all, then your argument is a little silly. Different ECU? Its not even the same thing anymore, nobody spent the time to clone the factory VVT settings, so its whatever some guys with a dyno came up with. Thats like saying yeah its a 1.8L ish engine, t24ish turbo, 4ish cylinders. Intake VVT looks to make some power (properly utilised with thousands of hours of map development time, but that doesn't mean the factory made the same power with the same hard, being constrained by economy, engine wear, and emissions!) Is the current 2.0L NC engine equipped with intake and exhaust timing? edit: nice low end bump on the VVT!

Would someone like to tell me what to try next on my cruise control on my '92? I push the switch and it doesn't stay on. I replaced the switch and it still doesn't stay on. Cruise actually works if I leave the switch pushed on. n8r fucked around with this message at 21:15 on Sep 3, 2010 |

(P0420 error advice) I've been getting a P0420 error constantly for the past few months, finally got around to fixing it. So, I just replaced both front and rear oxygen sensors and I still got a CEL after 50 miles, code P0420. Am I right in assuming I definitely need a new catalytic converter now? Looks like the previous owner welded a cat into the stock midpipe and it's pretty rusty now. Gas mileage is a bit less, but that could be me using the A/C a lot more now. No smoke or weird smell coming from the exhaust. Car is a 1999 with 116K miles with a Racing Beat exhaust. What else can I check/fix before springing for a new midpipe? Also, between the Roadstersport and Flyin' Miata midpipes, which one is quieter? My car sounds fine as it is, I'd hate for it to get too loud.

Check engine light question. OBD2 noob here. My 99 just got a check engine light the other day that hasn't gone away. It doesn't drive any differently and I don't hear/feel any misses, the plugs look good, etc. No exhaust leaks and I unscrewed and rescrewed in the gas cap. Should I unplug the battery and plug it in again? Does that even work on OBD2 cars? How can I get the code out without a reader? Is there any places in SoCal that read codes for free anymore? The car has cut stock airbox (with paper filter), Raceland header with relocated o2's, and ebay muffler. I've been running for mods for thousands of miles without issue so I don't think it's them.

I suppose the reasoning is so people don't clear codes and then go smog their cars. Not like that would really work anyway, serious code erasures reset their own emissions flags. There's 32 MILLION cars registered in CA, sorry if your state has about 31.5 million less? DJ Commie fucked around with this message at 03:27 on Sep 4, 2010 |

I thought that the way that OBD2 worked was that if it's related to emissions, there's a certain time/distance trigger that sets off a big red flag if assholes are resetting codes in the parking lot.

aventari posted:Check engine light question. OBD2 noob here. Not sure about 99s but on a 96(also obd2), if you just unplug and replug the ecu, it will clear all, you know, temporary codes. Slightly easier than unplugging the battery, perhaps. Not sure where the ecu is on a 99, i think they moved it from behind the passenger seat on the NB.

Thats an emission requirement, flag length is set by the car manufacturer. Drive cycles have to be done against certain requirements to reset certain flags.

Went through a drive through for the first time in the miata (I almost never eat fast food). The bottom of the pick-up window started about 3 inches higher than my roofline.
