no xr2 engine is going to be the same as any turbocharged engine. for a start the pistons are different. and if you mean like a mk2 xr2 cvh then there is also no hole for the crankshaft sensor pick up for the flywheel. a xr2i engine block will be similar but the internals are all slightly off and wont suit turbocharging period. probably fine if you just want the block though ( a xr2i i mean) but dont hold me to that
