I've never had a Palio one in my hands, but the consensus is that it just fits.

You can fit a P75 one, but have to relocate the servo take off -- the easiest (and best) way to do this is by TIG (Tungsten Inert Gas) welding. The photo shows a modified P75 manifold done by precisely this method.

In the old days there were people around who could gas (oxy/fuel gas) weld aluminium, but the current generation of welders are not taught it. (Blue goggles, big nozzle, low pressure, aluminium TIG rod, aluminium welding flux). We are a dying breed.

Palio manifold. The lump on the back could still cause problems as It's still tight.

You would have to use an Spi Map sensor.

The lump on the back looks like the boss for the P75 take off. Never tried it, so no guarantees. The Poles will know for sure.

Good point about the SPI MAP. There's also the issue of the Air Temperature Sensor (combined unit on the later MPI cars, together with the MAP) and whether either give readings the MPI ECU can make use of.

I can confirm that the Palio mani fits with respect to the servo takeof as on the pic. The lump on the back was no problem for me.

On my Mpi, there is a problem with the heater hose routing.

I have been running a 40mm TB on the standard car for about a week now. It still feels lumpy as if the Ecu is fighting to stabilise things. After about 5Krpm, the engine seems to rev a little better to 6K than with the 36mm TB.
I will put the old TB back on soon to confirm.
The 40mm fitted to the GP engine car running the Omex Ecu is still free revving and has a noticeable power increase above 5Krpm to about 5.5Krpm. I will have a play with the fuel map when I get a chance and see what happens. Then a rolling road session if things are looking promising. I am not expecting a lot due to the type of CAM that is fitted though and I don't want to pay £400+ for a 268/280 type at present.

When I had my 1108 with standard 4x4 cam and 40mm TB it did the same, pulled to 5.5k and pretty much stopped....

Now mine will pull all the way to 6.5k with the 866, it doesn't feel restricted by the inlet, more like a bigger cam will push the power even further up :devil:

Although it could do with the inlet being bored out a couple mm to make the most of the 40mm TB.

I'm looking forward to getting this reground cam and ported 75 head fitted to see what happens!
