Hi Guys, Need a wee bit of help, I have the chance of a 4 cylinder B2 coupe and as some of you are aware that is just one cylinder short of love and trust me I need love in all my cars.
Never owned a 4 cylinder before so what is the problems with converting to 5 cylinders of love, From memory the engine mount need fitting for 5 pot, is the subframe the same at the front?, back beam, disc brakes, shocks and coils I have from 5 pot, will they fit?, any thing else that you could advise on would be most helpful.
Thanks in advance.

lower bit of front panel on a 4 cylinder has a lot more meat on it from memory and may foul the crank pulley on a 5 potter

Front panel and subframes are definitely different. Not seen a 4 cylinder in the flesh but I believe the engine mounts are quite different and I would think the front body would need some fabrication, but not absolutely sure. Have a look at ETKA online, it shows the subframes and mounts on there.
