you will need
engine , gearbox, driveshafts, engine mounts , fuel pump in tank, main fuel pump, exhaust, engine wire loom, rear wire loom ( from rear lights fuel pumps etc), idle control unit (behind centre console and wireing to it) , relays, fuel pipes as they are bigger, heatshield at bulk head to stop brake fluid boiling up , dash loom and fuse box , rear disc brakes , compencator, brake servo , re route rear brake pipes for compensator, black box in (under scuttle panel) drivers side , gear linkage (inc pole from gear box to gear knob) as your will be too short, bigger battery, suspension upgrade as 1.3 too soft and sloppy, anti roll bar front, also preferable rear axle for rear anti roll bar, hand brke cables if converting to rear discs, coil, radiator, cooling fan, 14 inch wheels or bigger, cant think of any more but if i do i will tell you . you will not need the fuel tank as pump fitts in . just did this conversion on my golf last year. all goes ok. it is easyier if you have a doner car as i did.
you wont get all these parts from your freind as he will need some for his conversion.
