"Not if broken in properly"

That's the subject of--

The dreaded break-in thread!

<G>


Anyway, Back when GM was going to build a Wankel engine--
Initially, the apex? seals were a major problem, so the engineers came up
with a new design that was shown by testing to last far longer.
Management decided that the engine life would be too long, and told the
engineers to try again.
Then, to top the whole thing off, the engine would have to be re-designed
again to meed the emission standards that were to go into effect.
GM elected to kill the project, and converted the brand new plant from
Wankel engines to small in line engines, such as the one used in the Vegas.
(Another disaster!)

Doesn't matter as long as you KEEP it up or down until it's over 48.

Is it time for the dreaded tire thread now?

I never had any trouble getting it up until I was over 70.... oh, you
meant the top. Never mind....

Nope. The Dreaded Intake Thread comes first.

Mine is. It doesn't get below -20F very ofthen or for very
long, but it's been there.

What oil weight would you run in a turbo that is going to be run in
temps that range from semi-warm to extremely hot?

I am using Mobile One 10W-30 now. Would a heavier oil be of any benefit
during the hotter part of the year?

Thanks,

Pat

I doubt it, stick with the recommended.

That is what I figured, 10-30W has always served me well.

BTW, have you checked this Miata out? 1993 model, last year of the 1.6
liter engines in America. Your color, white, and with an automatic
transmission.

It's a bit pricey for a 1993 model, but it would probably look nice
sitting in your driveway with your white wheels mounted on it. :-)

36,000 miles on a 1993 model is pretty nifty if the various seals are in
good shape.
That's about 2200 miles a year, not bad for a weekend toy, not good if
it sat for years and/or rarely had the A/C run.
