What was the last year for the slant?

I shortened the quote but I don't see anything wrong with it. The easiest way to make the slant breathe is to shove the air in with forced induction. It is complex and must be done correctly for it to live, but it doesn't come with the same trade offs as big cam, big carb, lumpy idle hot rodding does. What is max hp people are making with a slant somewhere in the 600 range. That is pretty good for an engine that started at a realistic 140 hp. I might be buying a tig welder this weekend and if I do I won't be able to stop myself from welding up a stainless turbo header.

After having put together one of these little jewels, I can assure you that building the header was far and away, the most difficult part of the exercise.

Somebody needs to build these things (turbo-headers) for sale. My racing partner built ours and he had never built a header before in his life. It can't be that hard, once you have one to work off of...

All the other stuff is pretty much bust basic, bolt-together parts assembling; no different really, than building a normally-aspirated engine.

Tuning will be the next hard step, but a good, wideband 0-2 sensor/meter will make that part do-able, I think.

It's not magic; just engineering.
