People tend to get scared of things they don't understand. The Spica fuel injection system is really quite simple although to look at it is looks pretty formidable. It's very very similar to a diesel injection system (which is it's original application). With the advent of the internet, help is only a keystroke away. Also, the Master Jedi of Spica, Wes Ingram, lives just north of Seattle and has a long-running business that caters to the Spica fuel injection system.

I'll disagree with italiansedan man. The Spica system does not require high maintenance. Once in-tune, it will stay that way and the only regular maintenance required is changing the oil filter in the injection pump and fuel filters. Very simple and straightforward. The problem with a lot of Spica systems is that they are "tinkered" with rather than following the tech order and tuning them "by-the-book." Dealing with the Spica system is well-doable by someone with some mechanical aptitude and the discipline to read and follow directions. I have quite of bit of technical info that I email to Spica owners upon request. Lots of help available on the BB. Be not afraid. Again, welcome to BB.
