Turboing my 4afe 1996 corolla. Most likely buying this kit:

Pretty confident Ive got my head around the process, but abit clueless about the tuning. From what ive read it seems that a 1996 corolla can only be tuned with a standalone ecu such as a megasquirt. I only plan to run low boost, 5 psi probably. I have a few questions, any help is appreciated especially from those who have experience with similar models. 

• Should I consider any engine upgrades/ replacements prior to installing the turbo
• what else would need to be purchased that is not included in the kit
• what other things should i consider that may need to be made such as a mount for the intercooler
• what would be the easiest way to tune it 
• how long could i expect the whole process to take (only car I have, wont be able to drive anywhere untils its done)
