Its MPI though so would the ECU would have to be replaced as would the fuel pump. A lot of hassle for not a lot of gain

exhaust manifold? i cant see any gains to be had really. the engine is piss weak and isnt going to benefit or make any use of the manifold.

From what i remeber of the TV feature they did on the engine, you can do it, but there's hardly any gain, and you might even loose a bit of low down torque for a tiny gain in top end.

all the exhaust manifold are common, and the twin downpipe arrangement is a good gain to be had.
The inlet manifold wont work. they share a stud pattern, ubt the mpi has round ports and the spi has square ones. You can port them to match as they dont line up at all.
