A few Boxster technical questions??

[EFI tuning]

A few Boxster technical questions??

1.)Is there a single point to jack up the whole rear of the car? (IE Brace, Tranny or uni-body) Pictures would help greatly
2.)How do you do a coolant flush and anyone every have coolant line failure? (IE rubber hoses or water pumps)
3.)Can you Change the serpentine belt with out taking down the motor or tilting it? (if so how)
4.)Does anyone know the list of specialty tools need to rebuild a Boxster Motor?
5.)And last but not least does any company offer an End Usable Tuning device that piggy backs to the stock ECU or have software interface that can alter the factory ignition and fuel maps?

I just got a 2000 Boxster S with 18K miles on it. I would like to swap to a Carrera S 3.8 2005 motor in the near future. I will document everything but the biggest issues I for see are EM and electrical at this point. Can I use a 911 wiring harness and ECU?

Thanks in advance for all your help.

Also I always do my own work on my cars I will be posting detailed How to and share with fellow Boxster owners.
