Bob Moore's Coding Tips

My Car (1998-2004)

My car was a Mark 2 Mazda MX5, in Grace Green Mica with anthracite leather interior and a hard top (not shown). The engine was a 1.8 litre fuel injected unit. It did 0-60 in a smidgen under 8 seconds, and maxed out at around 125 mph with the hard top on, a l-o-n-g run at it and preferably a tail wind as well. Fortunately the MX5 is not too expensive to insure, provided you're not ludicrously young.... where ludicrous is defined as being under 25. Think of it as an MG that doesn't leak or break down :-)

One of the advantages of the MX5 is that it uses a normally aspirated version of the old B-series turbo engine from the 323 GTX Turbo (see below for tech links), so it's built to handle forced induction and you can get aftermarket turbocharger and supercharger conversion kits. Alternatively, you can leave the engine as is and rest assured that it is leading a very unstressed and potentially very long life : there are M1-version MX5's pootling around the USA with well over 200K miles on them and still going strong.

However, if you want a car for carrying large amounts of stuff around, look elsewhere. The Mx5 will carry you, a close friend, a change of clothes and a shared toothbrush away for the weekend. Mazda's adverts show the boot full of luggage, whilst carefully not telling you that said luggage is custom made to fit the boot. Having said that, the boot is not entirely useless - it swallowed my weekly shopping (NB: I do not have a family). Personally, I can't understand people who purchase a car like this and then whine about the carrying capacity : if you want a truck, buy a truck. Of course if you really want a car that can't carry anything, you could always get an MR2 <snigger>.

I made a few minor modifications, as is traditional for any MX-5 owner :

Problems during the five years I had with the car:

  • The stock Clarion stereo was really rather rubbish - I tossed it and got a decent Multi-CD player. There's plenty of space to mount the changer in the top-right hand corner of the boot, i.e. NOT where my installer put it <sigh>.
  • The boot (trunk) lid spring was weak. My first one couldn't hold the lid up after 6 months, and it's replacement behaved the same way. I only found out after JCT600 replaced the spring (with an unpainted one) that the tension bar can fit in three different detents to give different "springiness". Good grief. I later fitted extra sound-proofing to the boot to prevent drumming, and then it wouldn't pop open at all :-(. Oh well, that counts as a self-inflicted injury. 
  • The paintwork was rather prone to chipping. But what manufacturers isn't these days ?
  • It suffered from the known MX5 "idle-dip" problem. When the engine was cold and you came up to a junction and applied the brakes, the idle speed would dip alarmingly and idling became rough. The engine didn't stall, it was just a bit worrying. The problem did seem to be worse when you had extra load on the system (e.g. headlights, HRW). Interestingly, I was told by a knowledgeable soul that having the fan on the 1 setting made the problem worse, because the engine management system didn't take account of the blower load until it was set to at least 2. The problem only lasted for two or three minutes - once the engine warmed up, it went away.

    Note - if the engine does stall, it's a different problem related to an incorrect camshaft fitment, but I don't think that affected any of the cars which came to the UK.
  • The rear half of the window seals became detached from the roof after a year or so. This was a common problem with the Mk2. Mine was fixed twice, and the problem obviously recurrs.
  • There are little foam inserts in the soft-top seals where it meets the windows, to help keep the nasty water out. These gradually get pushed out by the window. Moral of this story? Open the door, put the window up, THEN close the door. Problem solved.
  • The alloy wheel centre covers are made of a plastic which doesn't respond well to UV light. They go yellow over the space of about 18 months. Of course if your car is garaged they'll take a lot longer to go yellow - probably just long enough for the warranty to expire.... Mine were replaced twice.
  • The alloy wheels... oh, don't get me started about the awful Mazda alloy wheels on the 1.8 MX5. They will start pitting within a year no matter how often you clean them, and can only be got back to a decent state with regular applications of Wonder Wheels. If the the Mk2 MX5 had an achilles heel, it was the alloy wheels.
  • The MX5 engine doesn't have hydraulic tappets. This allows the rev limit to be higher, but at the price of requiring manual adjustment every so often, and making the engine rather sensitive to oil viscosity. Net effect ? On a cold morning, it tended to sound like a bag of spanners. This engine is sweet once it's warmed up, but that can take a long - and somewhat rough - time.
