Can you do a build thread off it? I Would like to boa my xr4i and be good to have a thread I could look at to see how difficult it is. Someone at local meet said the boa is dead easy and the bob is more difficult to do.

I like the idea of 200hp instead of the standard 150 ( if it was ever 150 as standard lol )
better fuel economy and the lovely sound of the 24valver
