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!
