Do you map the engine with RPM vs TPS and add pressure compensations when bolting the turbo stuff on?
But its never that simple: for turbo I really need to replace the injectors (now 450cc, which I still had, to my old 1000cc injectors), so the injector map will have to be tuned all over again. But basically you are correct.
Clutch will also have to be replaced (I now use a lighter clutch) by then.
But I still need to get it running first; for now, still waiting for a few parts (oil routing connections...)
