The full kit does not include:

The tail kit is just the tail kit - so it is a sub kit. The sub kits are for builders who don't want to jump off and purchase the full kit and prefer to do it sub kit, by sub kit. The total of all the sub kits, cost wise, will be more expensive than a full kit.
The full kit includes the tail kit and all sub kits for that matter, everything firewall back.
The Corvair firewall forward is developed and is flying on the prototype Panther. The estimated cost for engine mount, cowling, exhaust and intake is estimated to run you around $2200. These are rough numbers for budgeting and should be close.
Please let us know if you have any further questions.
Thanks,
