I met Jeff Swords at Jack's fly in last weeked, and Jeff called me yesterday to answer a BUNCH of questions for me. They built Jack's engine, and did a fabulous job! Their prices are AT LEAST $1,500 less than anyone else I have talked to, and can customize as much or as little as you like. They will get you more power (horsepower and torque) for less money.
Well, I was, but then I ran in to some irritations with a couple of the Subie builders (there's much more to this story, but I don't want to go in to detail on the public forum-send me a PM if you want to know), and they don't seem to have a set direction for the future. I decided that I am building an experimental, but I don't want to experiment...I want to fly! So, I'll be going O-3xx...
I was sold on LASAR mags but now that I'm just a fuzz away from shelling cash out I'm reading some things that are less than encouraging about them so I'm almost back to ground zero on ignition. I understand about the changes when something like a Subaru is being considered. Have you given any more thought to assembling your own?
I should never have spent the time building the engine that have. I would have been way ahead of where I am today on the 7 if I didn't. However even if I did know up front what it was going to take I think I may still have built it. About the mags, I'm just a little worried about too high cylinder head temps in a fairly close fitting cowl. I'm probably still going to use the LASAR system though.
