I did it to gain drivability on the street with bigger turbos. The main thing is to keep in same year. 91 head with 91 block (just makes things easier) You will need different pistons beause the combustion chamber is smaller on the 4g63 head. down falls people say are you cant rev them as high as a 2.0l. I run mine to 8k with no problems yet. Keep doing research. It will come down to what you want to do with it in the end. (street or track)
