Hey all,

I just joined the list a couple weeks ago, and have been listening and
learning ever since.  I thought I'd chime in on the TR6 engine mod
conversation that's been going on.

I spoke on the phone recently with a guy named Darryl, at a company called
Racetorations in the UK.  They do high performance TR work.  I was asking
him how far you could push a stock TR6 engine with all of today's
technology.  He gave me a very encouraging example of an engine he has done
a couple of times:

Bore the thing out to 2.67 Liters to boost the torque.  Replace a lot of
stuff (especially the crank and pushrods) with steel so you can handle the
7000 rpm we want.  STICK WITH WEBERS!  I can't remember how the ignition's
done. I'm pretty sure the compression ratio was near 10, maybe 9-something.
$10,000 worth of just engine work if he does it all.  He says you get 220 HP
out of the thing, and that it runs like a dream, even driving to the grocery
store.

I like it because there's nothing high tech about it.  Just machining, some
high-strength parts, and precision.  No turbos, supercharges, fuel-injection
or anything.  I like it because it sticks as close to the idea of the
original engine as possible, but will blow away the the boxter sitting next
to you at a light.  It's like having my cake and eating too.
(yeah, I know, it's very expensive cake, especially considering the
necessary drivetrain and suspension upgrades)

It seems like the big difference is the increased displacement I don't think
I've heard anyone mention this modification yet, that's why I threw this out
here.  Does anyone have any comments on this idea. I don't really doubt that
it's doable, because I believe darryl that he's done it a bunch of times,
but I'm all ears.  Anyone heard of this before.

Look forward to hearing from you!
