1.4 tuning 8v (spi)

[5_door owner]

i have a 1.4 8v spi corsa b as a daily hack,

What i need to know, is will a mpi inlet bolt straight on or are the ports different shapes? and would the mpi ecu run with my current engine electrics?

Or is slapping a 32/34 webber on there gonna see the same results with less hassle?

the 1400spi top end is completely different to the 1400mpi

look in the spi tuning guide in the how to articles section, it may help, but simply slapping a carb on will not make it go any faster.
