Hi All,

I own a seicento sporting which has an on-again, off-again relationship with the road. Currently it's off again until some welding gets done and the nice people at the MOT garage give me a pass. I'd like to fit a 1.2 but don't want to pay out for an engine until my car gets the all clear. A local scrap yard has a P75 (which you don't see too often) and I was wondering which parts would be worth getting for my eventual engine swap? I've had the camshaft already but is there anything else worth removing? When I get around to the engine swap I plan to use an SPI bottom end to match my current engine.
 
I assume you mean SPI top end rather than bottom end :p

If it were me, I'd get the whole engine (inc inlet, throttle body, fuel rail etc), plus the fuel pump, plus the ECU and immobiliser - swap the lot over.
 
Get the hole engine. You could swap that in with stock spi ecu, with p75 fuel pump.

If you don't want to do that, get the camshaft, tb, exhaust and fuel pump


why would you mess about with a second hand fuel pump?
 
The fuel pumps are not cheap! Recycle...

I would get the whole engine, exhaust inlet manifold, loom, ecu, code box - as much as you can - if its not overpriced. Then you can take your time, research and decide which way to go with the swap.

fuel pumps are pretty much a service item. they aren't particularly expensive.

you wouldn't buy second hand spark plugs! well I wouldn't anyway!
 
I'll see what they want for the whole engine in that case and go from there. Really I wanted to avoid buying an engine until the MOT is sorted. I'm very keen to avoid getting stuck with a rotten sei (as in rust) & 200 quids worth of engine I can't use. At the same time I don't want to see the P75 get scrapped before I can get to it!

I thought there was an issue with fitting mpi engines to spi cars, like the entire loom needs swapping/ adapting to fit?

It's not worth saving the punto, it's one of those horrible 5 doors + has quite a bit of damage to the rear.

You are right. I think it's more difficult to fit to an spi car.

In that case take the cam shaft and shims.

Or get the engine and keep it till you have an mpi Sei. ☺

I think the exhaust manifold to cylinder head are different bolt patterns but someone will correct me if I'm wrong.
 
Yes, you'll need the loom, injectors, inlet manifold, ECU etc - that's why I said it :)

purf - the cylinder head to inlet manifold bolt pattern is different as the ports are taller on the MPI as it has cut outs to accommodate the injector for each cylinder.

I thought there was a difference between how the engine loom connects to the interior loom? So you'd need the interior loom and engine loom from a mpi?
 
No, I don't think you'd need that - but you'd need bits of the Punto loom for the injectors and the Punto ECU. I doubt it'd be plug and play with the interior loom, but then the wiring isn't that complicated so you could just work what needs to go where.
