Mm i got really wild idea..
You know, there is plenty of space on left of the motor, just
battery and thats it..
Idea would be to buy bonnet from some junkyard car of same model serie,
then add intercooler diagonally to that free psace, cut on the spare bonnet an rift where it would get cooling air and make scoop there, and to underside of intercooler add radioator to suck air on low speeds..
Who knows, this would prevent for moving radiator back
