ISUZU C223 Diesel Engine on VW 1200/1300 Beetle

[VW1274]

hi guys, have anyone here have done such as this conversion?

i mean for the engine space will the stock engine room suffice?
or should i cut my original, good condition engine room?

for the cooling straight pipes or bend pipes?
if straight but i didn't want to cut 2 big plates on the floor is there any other route?

will standard ISUZU C223 rad is enough or should i find something bigger?

if i didnt use any heater matrix where should i connect the "overheat pipe"?

thanks guys..
