Maybe Billy went over to some gwailo forum... they certainly have more constructive comments over there, because many gwailo have done home-made bolt-on turbo, since they have good fundamentals from their hot-rod culture.
Typical home-made turbo recipe:
1) Cut the stock exhaust manifold if possible, customize a flange to match the turbo's exhaust flange and weld it to the chopped-up manifold. That's the DIY turbo manifold..
2) Swap to bigger injectors and higher-capacity fuel pump. Swap out fuel pressure regulator also if required, to ensure that the engine doesn't blow apart from leaning-out.. Engine compression isn't even lowered if the boost level is something like 0.4 or 0.5 bar..
3) Customize the pipings to the throttle body and the air filter, and to the intercooler if required..
4) Use a T-joint at the oil pump to tap oil supply for the turbine, and whack another connection at the oil sump for oil return from the turbine..
5) Jerry-rig or customize exhaust connection from the dump-pipe of the turbine to the exhaust piping..
6) Adjust the actuator to limit boost at the desired level.. incorporate a simple manual boost controller as well..
Anything else?
Some of them are doing this on the stock ECU itself! It sounds simple, but local mechs will say that it's not do-able.. is there any other part of the recipe missing?
