Anybody else read the ITA Miata project article in the August Sports Car?

Apparently its now OK to substitute parts from a '99 Miata on a '96 ITA Miata (they installed a '99 diff). Isn't the '99...

Changing diff fluid in my ITA 94 Miata. Want to go to the lightest Red Line fluid I can get away with.

Anybody got a recommendation/bias/prejudice/horror story?

"The engine management computer may be altered or replaced. A throttle position sensor and its wiring may be added or replaced. A MAP sensor and its wiring may be added. Other existing sensors,...

Ditto for the '94 Miata

Well, I think SCCA missed one aspect of this FST-replaces-FV strategy: there's no date certain for completion of the process.

This could be easily remedied. Set a date on which all remaining...

Ty Till, a frequent poster on this board, was recently chosen as Worker of the Year by Rocky Mtn Division SCCA. Congratulations for a well-deserved recognition! :D

For those who don't know him,...

Had an occasion like this once. There's a fairly open stretch of road near my house, I live out in the country and the deputies don't hang around too much...

Would like to run 225/45x15 tires on my ITA Miata, but am having trouble locating a tire in that size that works well.

Avon makes one, but its a cantilever sidewall design is thus very heavy -...

Two ITA Miatas in Rocky Mtn Division SCCA last year.

The other guy hasn't shown up yet this year, his car was still mostly SM last season, but he hasn't entered in either class in '07.

Tried a set of 225/45x15 Avons last season, would describe thus:

1) 225/45 size is a cantilever sidewall design, which makes them very heavy :( . Approx 6 pounds per tire more than a 205/50x15...

Speaking from the perspective of one who has watched that sky-ground-sky-ground... movie in the windshield, I would never cut corners on safety gear. That goes beyond cage construction and...

Interesting...

Any way to determine amount of power loss in diff other than comparison of dyno runs with different diff's?

There are several other factors that would argue against upgrading a 1990 Miata to a 1.8, to wit:

1.6L diff is a well known weak point - ring and pinion notorious for shredding, so you'd have to...

Willyburgnuggerbears are SmashCAR fans, of course.

Has anyone found a chin spoiler for the Miata which works better than the Mazda unit?

Well, when OLN changed names, it stayed in the same spot on the cable lineup. Probably same on sat box.

Checked last night, Dakar coverage is only available on the standard broadcast feed, not on...

Yeah, Ty, "VS".

:( Shakespeare said we should kill all the lawyers first, but marketing guys weren't around back then.

BTW, VS was just added to the HD lineup on Comcast in our area.

Nobody mentioned Panasports. Wouldn't they fit in the comparision?

Yes, Ty, I guess this means I'm officially out of the Spec Miata community and in the IT community. :023:

Flow is a function of delta of squared pressures across the injector.

Raises a question I've been pondering. Is there any way to evaluate need for/benefit from increased fuel pressure other than...
