OMGHi2U "Built Motor Discussion" Links to Great Threads

Hey everyone. Here is a good compilation of reading material for when you get bored and want to read up on Subaru engines.

These are just some threads that I thought were great reading and have some very, very good information inside.

If you have a link bookmarked or know of one that you think should be added to the list...just post it up or PM me and I'll add it to the list!

Thanks and enjoy reading!

No they are all good except the one about supertech valvetrain and mild porting started by shaggy. There is nothing informative in the thread at all except how you can mess things up if you don't do good work and pay attention to details.
