Hello to you all! I know that there is a plenty of information here and its something really really helpful and i had many many hours spend reading.
The situation is. : I have a beloved seicento 1.1 mpi with MICRO ecu.
I also bought a p75 176A8000 engine.A video of Miller Corner who puts only 1200 block say that it works fine( around 60hp i thing?). Some threads say that i put block AND head with stock intake manifold-ecu-injectors-throttle body and it works fine(something a little more than 60hp?). I also talked with some people who say that it doesnt work anything of it and that i need a full conversion with intake manifold injectors throttle body and ecu of p75 to work fine.Also a guy here who works on remapping told me that the micro ecu cant be remmaped. I am thinking of : Using whole p75 block and head manifold and throttle body with seicento's injectors(which are bigger) and remmaped ecu p75 ecu. So i can have the 75horses of the p75. PLEASE HELP!!!!!! :worship::worship::worship:

The stock 1.1 engine with P75 cam and larger throttle body gets you most of the way there without all the hassle!

I ran an SPI Cinq Sporting with the above, plus a cold air induction kit and decent exhaust, it was a little rocket.

Hey Schumi-

(Sorry to hijack this thread)- by 'SPI' do you mean single point injection?

Are all Cinq sporting's SPI?

Yes, single point injection.

Easier to find a larger throttle body, too.

I’m awaiting a larger TB for my MPI Schumacher, but I don’t expect it to be too different to the SPI Cinq. Once done.

And yes, all Cinquecentos are SPI.

Thanks for going into detail on that

By inference- are ALL Sei's multi-point?

No, early Sei Sporting were SPI (and non Sportings were 899). Around 2001 they all went 1.1 MPI.

thanks for explaining that, Eklipze3k

I think cant a spi 1.1 with 866cam be faster than whole 1.2 p75 motor with multipoint. Im thinking of swapping ecu.
Using reprogrammed iaw4afm7 from 1.1sporting with p75 intake manifold ,1.1 fuel rail (make it somehow fit) and throttle body of 16v punto 176 which is rated for 80hp (also make that fit on the manifold).Costs about 350euros here for all of them. Has anybody done it?
The article of mariocing and custard i thing are the only which explain some thing clearly. They both say that with stock ecu, throttle body and else, with block p75 and with or without the head of p75 the car works fine.But how much are you gonna gain with only the block(i thing 60hp) or with the head of p75?
If those articles are right.Which i want to believe they are cause else i have to swap my micro ecu whatever i do. The main problem is which is the easiest and economical way to have the 73 horses of the p75. Im really confused.
And there is also another option of using p75 ecu and harness with both p75 injectors and throttle body but there we have to other three problems ,with first be the throttle cable and second be the fuel pump(will work with the stock or i will have to find return lines punto fuelpump and so on?) and third be the wiring. Really i cant find any documentation on that.

hi i wan to ask if is possible on a budget to do a soft turbo on 1.1 mpi ? can some one help ? or if no then somthing to meake stok go a bit more a life.... in this days

Welcome to the forum Mrbee - thats a very broad and open ended question. But lets try break that down a bit concisely..

is possible on a budget to do a soft turbo on 1.1 mpi ?
erm, yes and no, depends entirely on what you consider doing on a budget is. I would guess just by the fact you are asking these questions though that your not gonna be able to do this all on your own - if your gonna end up paying someone labour then no it wont be cheap at all. Can you get the parts together to turbo one relatively cheap, yes.

can some one help ?
yep, plenty of helpful people here to give you advice but you need to do your research and come back with questions on stuff you don't quite get or need more explanation. All the info is there, you need to sit down and read some build threads, theres been plenty of turbos on here over the years - and they are all different as there is no 1 right way to do stuff like this.

or if no then somthing to meake stok go a bit more a life....
again, loads of stuff, possibilities are endless. Knowledge and imagination is all that is required (and some tools probably lol)

hi yes im asking si never done na to a turbo i mess by for with engine mods but was all reedy turbo i got tools and space but dk what turbo way is need it ... if this well run on stok ecu ?? cuting and welding dow pipes done that in pasth to .. just some one to direct me .. i got some mechanical knowledge

on a budget i men like list of things to close all under 400+/- £ in parts.. or less

wuth turbo use ? i was wondering aboint 1.0 from eco bost or 1.3 panda diesel... with fuel pump is esy to swap injectors and a bit of wiring well be needet to i huess on stock loom... wat i want to gain ?

thinking of soft turbo 0,3-0.5 bar to get 20-40 bhp

I am yet to see a working soft turbo setup for Cinq/Sei that so many seem to long for... 400 quid won't cut it, soft or hard, unless you go for trashed second hand parts of uncertain quality and do not do other required upgrades for this, like brakes and suspension. In my project I spent that amount more or less on welding alone (delegated to professionals).
