The truth is that any well done engine swap into a TR6 will have to replace
almost the whole drivetrain especially at 300 HP. There will be almost
nothing left but the shell.
I've got a couple of fetishes. I want less weight and more HP. If I was
going to try it, I would probably want to give a supercharged rotary engine
a try. That would be about 300HP and a few hundred pounds lighter. (I
already know the exhaust won't sound right though)
There are so many British cars I would think about butchering for this idea
but I have kind of a soft spot for keeping the TR6 relatively intact.
But then, I'm just nuts.
