pros and cons of turbo ??

[dub-disaster]

As the title says whats the pros and cons of going turbo ? ,
   i have taken my g of the road for a while and was gonna sort the chassis with a sub frame some new 256mm brakes and genrall renewing of bit n peices, i was then going to drive it in the summer then go for an engine overhaul n go turbo in the winter of the following year but ive picked up a reasonably priced turbo kit with almost every thing i need to go turbo so i may have to swap the order in wich i do thigs around slightly but i have a few turbo questions

  Firstly what are the pros and cons of going turbo, will it be ok to turbo my current 115k g40 engine without having a rebuild first? should i be looking at boring it and using foged pistons?

  Whats the power delivery like in a turbo , i was looking for a nice drivable power that i can drive daily good mid range grunt as well as top end power.

  Would my g need any other mods to handle any extra power the turbo could provide like a lsd , or would i be better of doing my chassis mods first to help handle the power then doing my engine i just got this turbo kit as it was a bit of a steal really, or should i be waiting any advise from anyone who has been alone this route with there g would be much appreciated thanks guys

Pro's...

good reliability, excellent tunability, awesome efficiency, no more engine parasite  , free power.

Cons...

erm, if you like servicing stuff you will have to take up another hobby.

A G40 with a turbo and 130-150bhp would be really reliable and a nice daily driver...

Only con for me is, it's not original- but my car is a GT anyway, and I'm not too arsed about being OEM.
