So I bought a 2004 Mazdaspeed Miata, and now I need to sell the 97 NA...
But I wanted to ask some other MSM owners a few questions...to start off, have you had any problems? Mine has 52,000 miles on it, was a lease vehicle so I think it was dealer maintained. The only thing I have noted thus far is that the intake boot, the one that comes from the intercooler and then makes the 90 degree bend into the throttle body, was pulled back from the 'lip' on the throttle body. It was not sitting flush with the throttle body case. It did not come off, but it was not on all the way. I had to squeeze one of the spring clamps below the throttle body, pull the whole elbow piece up a shade, and then it pushed onto the throttle body no problem and I tightened the clamp.
Idle quality...it's a bit rough, harshness-wise. It's rougher than the
1997 NA. anyway..is that normal? It holds the idle speed okay. Once you get off idle and start driving it is smooth all the way....The other thing I've noted, the turbo doesn't seem to come on until about 3500-4000rpm, but once it does, it comes on -fast-. I mean at WOT you're bouncing off the revlimiter before you can blink twice kind of fast. But if you are a bit more...relaxed.....it comes on a little more smoothly and you can hit 2nd without a problem...but then when you go from 2nd, near redline, to 3rd...it almost feels like it sags a little before it comes back on again...normal? This is my first turbo car so I don't know....
Also..all these vacuum lines under the hood are maddening. Some go - through- the strut brace, I see at least 4 solenoids, one or two one- way valves, and under the intake above the alternator something that looks like a dashpot...ugh. Add to that the tiny little lines that connect from one place to another on the intake.....I'm in over my head in terms of grasping the big picture. I've done clutches, timing belts, water pumps, and so on. I did the water pump, all hoses, belts, timing belt, CAS o-ring, and so on on the 1997....and it was pretty easy all things considered, if not a bit time consuming. But I think I need to buy the factory service manuals post-haste and start reading...I have an idea this MSM thing is going to be a bit maintenance intensive...
