Hi guys, been a while that i now have my cinquecento sporting. My goal is to get around 150 bhp from a turbo setup on the 1.1 fire engine. With some help and advise from the more experienced cento tuners here we could make this dream come true

I'll try to post as much pics as possible, could be usefull as a guide for newcomers that want to go turbo later on.

First step i'm gonna take is to rebuild the full engine to make sure it doesnt leak oil and can take the pressure.

Here a few pics with dates:
25 Feb 2011 - The Engine before i started on it.


25 Feb 2011 - Took off the filterhousing, distribution with plug cords.


25 Feb 2011 - This is the coil holder i took off first, as u can see it leaked a bit of oil, could be cuase the seal might be old.


26 Feb 2011 - I was going to take out the cilinder head today, but it's raining all day. I work on the car outside in the parking lot, so i depend alot on the weather.

Question: I was doing some research on the site and would like to use a gt1549 turbo for this build. What confuses me is that there are so many turbo's but cant figure out off wich car to get it. Any tips? Keep in mind i live in Holland. Scrap yard turbo is rare to find, so have to buy it off local advertisement site.

t15 and gt15 turbos are the same (dont ask my why but thats what ive found)
A GT1549 would be ideal for your setup. slightly larger then the astra turbo

just find one that fits your requirements to make fitment simple.

GT1549 is from a Rover 25 TD, it looks like this; http://tackycheese.net/images/cars/cinq/turbo_test_fit/

Elbow is part of the exhaust turbine housing, makes things a tiny tiny bit simpler

150bhp is certainly possible. To get it reliably, though, you really need to go to MPI, forged pistons and a decent aftermarket ECU.

If i were to use the SPI with an extra injector, with intercooler, standalone ecu, on stock internals give me?

Something like turbocinqy's first turbo setup. doesnt have to be 150 exact but in the 100-150 range is nice. Heck 108 hp is double the stock engine

I think that Finger's main point is reliability You can of course get 150 or even more (if you dare) from stock internals and SPI, like Dennis (Turbocinqy) did (but mind you he has forged pistons, and I think he did have them already in the first setup, but I am not sure), but then ask him how well his car runs The inherent problem with all SPI turobs is, according to what I have been reading around here, is underfueling in external cylinders, hence Finger's advice on MPI. But this is my own speculation

150 is about what the ex foxyemz/alanhelen/donna .etc car gave in its final form. Poor thing was showing signs of detonation on (way better than stock) Mahle pistons. Its history so far (has passed into new hands) is pretty well documented here (see posts by J333EVO and the previous suspects).

Problem is, very few decent ECUs will run the one injector plus one more set up and nothing that's out tere is really much cop for the SPI (and it's getting stupidly expensive for the carp it is). Why not get an MPI head from a Sei or Punto? Straight swap.

Although water injection and all that has its place, using it as a band aid is going to lead to trouble.

Prob is i already bought the head gasket set for the 1.1 fire engine

I found this on a the web:
1242cc 8V MPI
This is the best flowing head on the 8V engines and can still be improved on with porting. Testing of the stock head indicated flow for 250hp, flowbench testing on my ported head indicated flow for 350+hp but I doubt anyone can get a FIRE engine to these power levels without a large investment..

1242cc 8V- 75hp (MPI)
This is the cam used in the Punto 75 mk1*, it produced 15.4hp over base.

Note: These tests were performed on a stock 999cc SPI engine (fresh rebuild with complete break in), results on other engines may vary.

the source is http://turbofire.no.sapo.pt/parts_info.htm

Think its gonna take me too long to get all those parts together.
How much will it cost me to get all the bits and pieces to get atleast 100 something hp?

In a way if i combine the article info and what u said, means that the 1242cc 8v mpi head is straight bolt on the 1.1 fire block, wich could lead in better flow and power increase?

The cam he talks about here is already in that head right?

I get a feeling its gonna cost quite a buck

if your looking for 100hp then the 1.4 16v would be you best bet, low cost and good reliablilty compared to a silly hp 1.1 8v

also fingers what did blue put out before it went pop ?

It's as a starter, start at around 100+ then upgrade easy to go more hp.
And i saw on same source this:
Believe it or not the best base for an "all out turbo engine" is the 999cc/1108cc , this when referring to fire engines obviously. The 1242cc 8V being the best for a "low pressure turbo" system.
Note: The new 1368cc 16V engine is not suitable for boosting since it has an aluminum block and 11:1 compression, moderate boost would blow the pistons out of the bottom!!

is this a lie? Just want a little screamer. Want some power, as i like sprinting 1/4 miles ect

It's old information, remember the punto / bravo tjets are pushing 200bhp from the 1.4 16v turbo (albeit with different piston/cranks)

About 115. Alanhelen's car was a further development with better pistons and lots of piggy back stuff.

8v MPI head is bolt on, straight fit. There's plently of stuff on the 1.4 16v swap on here by J333EVO, Kripit and Arc.

The 1.4 16v and Tubs have very different characters, but bear in mind tat both need substantial impprovements to tyres, wheels, brakes and suspension.

Oh noes.. it's more then i tought.

The main thing was that i was going to rebuild the engine so it needs to get out of the car anyways, thats when i figured, hey its out... why not make it a notch faster... maybe turbo.

But i wasnt expecting to get a whole new engine. Think i need to do what i can do on this one and get a other engine to work on.

I bet there isnt much i can do with the 1.1 8 v to make him a bit faster with out giving out loads of cash huh? I once went to WOJ and saw his turbo project. I was excited about the 1.2 punto swap, till i heard about the 1.4 swap.

What could i do? any suggestions?

How much modification is the 1.4 16 v? what gearbox, motor supports, ecu, shafts ect am i gonna use? Just to compare info and see what would suite me better.

fitting a 1.4 16v will work out cheaper, be easier and (probably) be more reliable.

It sits on the same mounts, uses the same gearbox, same shafts etc. Search and read for further info;

https://www.fiatforum.com/cinquecento-seicento/176286-my-1-4-16v-cinquecento-development-thread.html <-- my thread on fitting a 1.4 16v to my cinq

and there is a guide by D4NS in the guides section specifically for 1.4 into a cinquecento

Back on the turbo front, Tricker's car is well worth a peek -- very original way of going about things.

The low boost tubs seem pretty reliable (up to about 100bhp) with an SPI set up.

Not sneezing anymore going minor mods on 1.1 fire!

U did quite a few adjustments to fit that 1.4 engine, ur plus is u have a garage, im working on the street and the weather kills my hands. Think it's a project worth keeping in mind. No space and little time atm holds me back from doing such a big swap

Think for now i should concetrate on this engine, i already got most of the parts and cant bring them back, too long ago. Main reason i was gonna rebuild it is cuase it was leaking oil like crazy.

Im not gonna invest full N/A in it but i'm surely not putting it back together without doing nothing to it

Been reading a bit and using the search alot, wonder what these mods can do to a 1.1 fire:

-Bigger TB >32mm (off what car is bolt on and bit bigger)
-Minor porting and matchport
-hear uno 45 inlet manifold better flow, dunno if tb fits on it.
-P75 cam
-P75 exhaust manifold the 4-2-1 is much better.

Maybe lighten the flywheel a bit.

Dont expect miracles, but im sure ill feel te difference.

I think maybe 65 bhp or so more would be always welcome.

Re: Not sneezing anymore going minor mods on 1.1 fire!

There are bigger/better TBs out there (Alan Helen's N/A car -- I think Ming still has it -- had one). But essentially, that's it. Remember you'll almost certainly have to re-set the valve clearances to fit a P75 (866) cam. You'll probably ave to shorten the P75 downpipe. You could look at a chip, too.

Better front brakes and decent tyres are a real performance enhancer.

Re: Not sneezing anymore going minor mods on 1.1 fire!

best mod you can do, price to power wise is to bin the 1108cc and fit the 1242cc
