I have recently aquired a turbo from a mazda 626. Its in great shape and wanted to put it on my car. I have the resources to make it fit and work corectly. I just wanted to know should i rebuild my engine befor i add boost. I have 1.5 16v mpfi. Dx block and head with si intake and injection and ecu, also accord TB. Could i get a way with just replacing the piston rings? What other parts would need to be upgraded or just rebuilt? Any help would be great.
