whilst waiting to for my old man to finish with the garage so i can get my hands on my mk1

, ive been passing the time looking for bits and bobs to buy for it and have now decided im not going to rush it and get everything done at the same time (re-spray, sort roof out, interior and engine conversn), im stil un-decided

between 20v turbo or vr6 it will proberbly come down to what money i have at that stage but my question is can i use my standard gearbox and flywheel on either of the earlyer mentioned engines? as there are quite a few autos about going fairly cheap
thanks in advance
mr mk2
