if the mira 660cc turbo engine is the same generation as cuore's stock engine. then what you can do is get the complete wiring,sensors, dizzy, ecu, turbo (with manifold), and intake manifold, and swap it on the stock engine (basically everything except the 660cc head/block). your engine will handle the stock 5-6psi of boost. and should result in alot of power increase compared to stock. 1 thing extra you will have to do is...get a high flowing fuel pump and a fpr... to increase the fueling, as you will be having more displacement/compression ratio, when using the stock engine compared to the 660cc one. good luck.
