The 3kGT engine fits bolt-on, but new splines for driveshafts had to be made to fit the transmission box...
Also, the fans had to go... (For the radiator ;)) New smaller ones is now mounted...
It goes real well! Altough it weighs about 1,5 tons, it does 0-60mph in 5,3 secs!! (Measured using a G-tech instrument...)
