Put a VR6 into your A2

 
C=Corrado P=Passat G=gti vr6 J=Jetta glx vr6

A)Neccessary Items for conversion:

 1)Engine/trans/downpipe/cat: c-vr6, p-vr6, g, j

 2)Rear subframe: c-vr6, g, j (passat does not work)

 3)Front crossmember: p-vr6, c-vr6 (A2 can be used but does not
hold up well)(a3 gti, jetta does not work)

 4)Radiator: c-vr6 or g60, turbo diesel? Must have outlets on
driver's side. (a3 and passat is too tall)

 5)Radiator fans: c-vr6, (p-vr6, g, j, yes but you must trim off
1" from bottom of shroud), turbo diesel?

 6)Radiator hoses: corrado vr6 fit perfect

 7)Pedal cluster: c-vr6 or g60, p-vr6 or 16v i.e.-any car w/02a
tranny (a3 gti, jetta will not work)

 8)Cable shifter: c-vr6 or g60, p-vr6 or 16v, g, j

 9)Air intake: c-vr6 or aftermarket (corrado vr6 p-flow bolts up
perfectly to a2 w/vr6)

 10)Wiring: pre 1990 cars-splice in vr6 engine harness. 1990-92
a2's plug in vr6 engine harness but use 86-89 16v cluster spliced
in for functional tach and adjust. If using the a2 cluster, use
corrado g60 speedo cable to run a2 speedo.

 11)Exhaust: custom bent or (highly recommended for the $)
techtonics 2.5"

B)Optional Items:

 1)Vr6 power steering: c, p, g, j All racks work fine. g,j,p
resorvoir must be swapped for a2/corrado resovoir, and a2 low
pressure line makes a better fit than g,j,p metal pre-bent line.

 2)A/C: Corrado vr6 or custom make a2 lines to fit vr6
compressor and use either r12 or 134a

 3)ABS: master unit from c-vr6 or g60, p-vr6

 4)5-lug brakes/suspension/drive axles/rear axle: c, p, g, j- if
you're going to use it, use it all. vr6 axles, tie-rods, and 
control arms are longer so if you're staying with 4-lug, don't 
use them. I've driven a vr6 a2 w/4-lug and honestly it's really 
hard to tell any difference. But I definitely recommend 4-wheel
discs w/11" fronts either way.

 5)Gas tank: g, j, (passat or corrado???)

C)Additional Info:

  A)OBD1(92-95) OR OBD2(95-99)?
   1)Advantages to OBD1
    a)easy to make tach work in a2 cluster
   2)Disadvantages to OBD1
    a)some have pricey dist. cap/rotor
    b)ECU must be socketed for chip
    c)turbo and super kits not avail. yet
   3)Advantages to OBDII
    a)"smarter ECU"-has more diagnostic abilities
    b)easy chip instalation
    c)ready for turbo/supercharger kit
   4)Disadvantages to OBDII (only in a2 conversion)
    a)No tach in a2 cluster


D)Modifications to make engine fit:

  1) Hammer in passenger side frame rail to clear harmonic
balancer &W/P pulley
  2) Lower pass. rear motor mount by removing lower "gold/brass
colored cup" and turning "black cup" upside down and inserting
rubber mount in black cup. 
  3) Cut SMALL hole in firewall for clutch master cylinder
