A little tinkering as always, this may not amount to much but we will see.... So I got hold of a Meg 4 RS 280 twin scroll turbo and manifold. The 1.8 is basically a stroked 1.6 engine from what I can tell.
Anyway the thought process here, twin scroll gives quicker spool and wider spread of power. This turbo on the 1.8 supports 320-330bhp of flow so should do similar on an engine with 180cc less displacement. The turbo I have on there is a little laggy, not massively as the edc gearbox can keep it on the boil nicely once spooled. That said, the fuel system is pretty much tapped out already. Bigger hpfp and injectors would be a nice touch...
Side by side the rear housing is bigger than the Clio item with a bigger turbine, compressor side is not much bigger though the wheel looks like the ones that are fitted to the hybrid clio units.... The 280 turbo runs an electronic wastegate actuator and that runs in reverse of the normal setup, it pulls to open vs an atmospheric with pushes to open. Whipped the arm off and rewelded it 180 degrees around. Going to pop down to Forge Motorsport tomorrow and have them knock me up a custom actuator for it. The Nissan intake adapter fits nicely, though needs a blend on the housing, but it would allow me to mate it up to my current intake setup if I chose to fit it...
Anyway, a bit of waffle and a few pics.
