I don't know much about jag motor's but, sort-a kind-a in the family now
(through MG) would be BMW... and a "baby-six" from a 325i or 525i would
possibly fit the bill (as well as being alot more plentiful than the jag
motor).. not incredibly expensive, L6, overhead cam (or dual overhead,
can't remember.. possibly either depending on year/model). Making one fit
might be hard but, another thought would be the "super-eta" motor from a
1988 528e.. ~145hp, _gobs_ of tourque and supremely quiet.. with a redline
around 5500.. the "i" motors would put you more towards honda'esque
redlines in the neighborhood of 6500-7200. It would take a fair bit of
research and, some or all of these might be too long/wide or both.. Not to
mention the whole ECU and harness you'd need to splice in and, that's still
without any thought as to what trans and how to couple them and use the
bmw's completely hydraulic clutch.
Just a thought.. but I do tend to agree with you about V's.. not that I
don't like them but, the L6 in my 528 is one of the smoothest motors I've
ever had, and with the right exaust it can "blap blap blap" and "burbble
burbble" as much or as little as you want. I've had many cars and many
different configurations and, they all have their merrits and
disadvantages..
If only I had unlimited funds and a little less sanity.

Subject: The perfect motor swap...
Saw you folks talking about motor swaps for TRs and had to throw in my
$0.02.
I don't like V motors. I have always thought they were rough. My
mother-in-law has a very nice Mercedes with a 5.6 liter V8, and it might
as well be a Chevy. There's just that weird sub-sonic V rumble that comes
from that cylinder arrangement, be it a V-twin Harley, V-6, V-8, V-10,
etc. That staggered firing order and loping just doesn't appeal to me.
I realize that's EXACTLY what appeals to a lot of other people, but for
ultimate smoothness I've always thought straight sixes ruled. ( In
theory, a straight-eight would be even better, but I have not had the
opportunity to get in an old Buick or Mercedes racer to get a sample )
I too have thought of replacing my healthy little four-banger in my TR4
with another motor. Not with a V-8, aluminum or otherwise, but with a
pretty little six, but I've never found a donor.
What *I* think would be perfect motor swap is something like a 3/4 scale
Jag motor. A 2.5-3.0 liter double-overhead cam ( no pushrods, please ) six
with an aluminum head that would fit in the confines of my TR4. So it has
to be short. It would preferably be British, light, plentiful and cheap.
How is that for a tall order? Like I said, I've never figured it out.
Is there such a thing?
