1600/1700 Antz Wrong size maybe but it's still the right engine for the car plua you can keep the 1300 under the workbench just incase you want to go original concourse one day
Why don't you get yourself a nice cylinder head first then get the bottom end at a later date?? I only fitted my new xflow beginning of last year but the bvh I had on the old 1340 for about 4 years or more
