Some of you will be saying no dont do it i know.. But me and my brother have been thinking.

He had an a3 1.8t sport on the road. Fmic,induction,decat,forge actuator set at 1bar and a remap..est realistic figures 210-220bhp or somewhere around that.

The car was parked and and a tractor reversed into the back of it and writ it off! So he just got the car back from the insurers so he was asking me if i thought it was possible to put the running gear from his a3 into the mk1.

At first i thought dont be silly..but then after seeing the amount of different engines people have been putting in the old cars i dont see why not?
I know there is a company that do a kit to run a mt75 gearbox to the 1.8t engine but the kit alone is near £700! So the idea i had was this..(this is where i need help)
I know vag do AWD gearboxes...and i know these can be converted to Rwd by welding the front drive difs.

How hard do you think it would be or is there a company that could make one prop shaft from the vag box to the english rear axle?

I know other work will be envolved with fitting this box like gear stick position,gearbox mounts, 1.8t propshafts also have a center bearing if i mind right.

any help is good help
