I have BTDT and thought it was worth my money, but
I had a clear vision of what I was trying to create-
a high performance S2- a car not available here in the
states at any price. In the end you do this because
you want to, not because it makes sense.

Yes they do, I have 2 pages of new parts they
consumed doing mine. They do the timing belt, WP,
seals, etc. at the front. VC gasket. A bunch of new
sensors. On and on.

Ah but the wires... I did a lot of research before
going to 2B, and there is well over 100hrs of labor
just getting the wires straight. And that is if you
know what you are doing. Others who didn't spent
closer to 300hrs. getting it right. Basically, you are
combining 2 harnesses into one. Trip computer,
climate control, dashboard, etc. need to be massaged
in to the new ECU harness along with the 20vt engine
sensors and controls.

As I said, the heavy lifting is on the electrical
side, the mechanical stuff is a small fraction of the

upgraded suspension, or at least replace all the tired
old bushings. What about the IC? you will need some
front end work to accommodate it.

The old one, so it better be in good shape.

That is the sobering truth. But again, I had a goal
and spent a couple years researching the options. In
the end 2B was the hands-down best choice... for me.
It is not a trivial project and not to be entered
