Do I need to change ecu or anything? So the bwa definitely goes in and I won't have any problem trying to get it starting? Do I not need loom ecu or anything considering it is a diff engine code? Have you done this before? Thanks for your reply

Only difference is the compression ratio, so no need to change anything but the engine.
I am running a cupra 245bhp BWJ engine in my AXX GTI with AXX ECU, to establish my credentials

Do I need to change crank sensor from my engine map sensor or anythin or just plug and play? I've heard I need to change fuel lines as the lines to my hpfp one is a banjo bolt and on the bwa engine the fuel line to hpfp is a hose

hpfp is diff

Use your old HPFP if you like, only the connector is different then (banjo instead of later connection). The rest of it - mounting, piston, outlet & capability are all the same  :happy2:

Is all wiring the same also the same? I have sourced a bwa engine but the lad said some wiring may have to be relocated? Is this true? Thanks for your reply much appreciated

Different cam, different Pistons, probably some other tweaks elsewhere. . .

Different engine code signifies differences. .
