I guess making room for a turbo?
Biggest issue I can see are the secure mounting (which shouldn't be too hard), and the cabling (quite awkward to run that sort of cable, ask any chav who has fitted a 10,000gigawatt amp in the boot
).

yep.. and not only that.. the only part you cant estimate is its not for omega.. I decided to keep it as it is.. as the car is very healthy and it took me many years and a serious cost to bring the car to that point.. may be only I will bore it to 3.0 .. and its my long range transport so I dont want to face any problem while on a mountain passage.. and one more point even with that engine (currently 188 hp) , it can travel many times the legal road speed ..
but clit definitely needs space under the hood.. not only battery also all air inlet boxes removed .. and in re-building stage now..
ps: at first I decided to turbo the miggy.. apart from the cost, its not my daily drive because I have a big big big parking problem in job
although I prepared all necesssary info and read zillions of pages , I finally decided for clit
