Saqib,

Did your friend tell you what rpms the engine was turning when it threw
a connecting rod??  It seems a little strange for that to occur at normal
highway rpms ~3500.

I was beginning to teach my friend how to drive a stick on my '85 Coupe GT.
At one point, he commented, "So driving around town is easy, because
I can just leave it in second gear."  I then tried to explain to him that
you shouldn't drive down the street in second gear at 5000+ rpm, because
it would put more stress on the engine than necessary.

I just have nightmarish visions of your friend driving down the highway
at 70mph in 3rd gear, pushing 6000 rpms continuously for a couple of
hours.  Then it wouldn't surprise me that the engine threw a rod.

$400 sounds reasonable, for a straight engine swap.  Note that you would
need to retrofit the knock-sensing ignition control system from the 2.3L
engine if you go this route (and the 2.3L IS a nice upgrade for these
light cars...just ask any of the 2.3L Coupe GT owners).  Otherwise, the
2.22 Coupe GT and 4000q engines are 99% the same (different exhaust manifold,
different oil pressure sender/switch).  Make sure that you do not get an
early ('81- early '84) Coupe engine, since these are the 100hp 2144cc CIS
engines, which are not [easily] compatible with your 4Kq.

Later,
Eric
