Hi i have a 2001 seicento sporting have read a few notes on here saying thats its possible to put a punto 1.2 75 engine in a seicento would like to know how hard this is too do and is theer any particular 75 engine as in year etc that only fits ,plus if there is anyone that cabn do this what would you charge thanks

Technical Punto 75 engine in seicento
a quick search would of helped you https://www.fiatforum.com/cinquecento-seicento-faqs/93884-engine-swaps.html 
I had a poke through some of the threads but found nothing 100% aimed at the conversion.
interested in this if someone knows the links........

Hi, sorry to jump in on your thread ezepc,
I have a 2000 w seicento abarth, whicj I gather is SPI, meaning the simplest conversion would be the punto 60 spi engine correct?

I have a 1999 900cc what would be the right engine for that i have been told it has to be a punto engine form 97-99 otherwise different looms ect but dunno which engine is it the 65 or 75 alls i want is best performance and no agro getting the thing in can any 1 sugesst anything

Yes i too alrady looked through but nothing too clear i dont want to just go to the scrap yard ask for a punto 75 engine then relise theer are only certain years or codes that fit a 2001 seicento 1.1 sporting
2000 was the change over year. if you have square airbox its SPI if you have round airbox its MPIHi, sorry to jump in on your thread ezepc,

899cc engine is completely different. so you will ned practically everything including engine mounts.. dont bother buy a sporting as a better base. and use FAQ as previously linked
SOZ about spelling in last thread would be really greatful if anyone could give me the exact engine i need for my seicento thanks
all p75 engines are the same.....
aaah besides one thing... get one that dosent have the cam sensor... so mk1 punto and very early mk2
hi
ok i have just fitted a 75 engine in a 2001 sei mpi and its not easy and its a pain to sort the ecu out as the 75 ecu is totally different to the sei mk2 so if you are really looking into doing a 1242 swap into your sei do a 16v swap as it is actually easier in the mk2 due to ecu
the problem stems from the electic power steering which is run from the sei mk2 ecu but the engine map (for the 1108) doesn't run the 75 engine very well plus due to the way the sei mk2 inlet is wired up it all needs lenghening to fit the 75 inlet and tb, you could get around this by fitting the 1108 inlet to the 75 head but they dont mate up very well and causes running issues so then you will end up fitting the 1108 head to the 75 block and then running it of the sei ecu but it will then pull really badly over 4k rpm at which point you will be sick of it and pull it out and fit a 16v
save yourself the time and expense and just fit a 16v to start with and fit a mk2 punto ecu or get the sei ecu re-mapped
so you know i have spent the last 6 months trying to get a 75 engine to work in a sei mk2 mpi and we have finally given up and are now going to fit a 16v lol

the biggest pain in the ass will be the immobilier i would of thought because it wont work with the seicento coded keys
any idea if it plugs into the standard sei loom?

Punto 75 ECU plugs directly at the spi loom. You only have to replace the single injector connector with 4 connectors (in parralel) for the P75 injectors.
If you get an early non coded P75 ECU, you can just start up and go. Otherwise you will have to change locks and keys (to have a fully funcional immo), or tie together a P75 key with the immo antenna, somewhere under the dash and continue to use your regural keys.
P.S. Fuel pump will also need to be replaced on an spi Sei, with a 3bar one (P75 will do). I use a Fiat coupe one.

do you mean if your seicento is multipoint.. ?? if so it should be a case of just extending the wires
