Here are what makes a thread....the pics :D (y)

As you can see, it has a different water rail, different mount (already resolved), an aircon pump that needs to come out, remounting the alternator, hopefully the 1242 mount will work?, finding a new sized belt.

The intake is getting junked, as is most of the wiring, then its new filter, oil, swap the spark plugs over, make a plate to mount the coil, and then maybe I'll fit it :D

I'm unsure whether to run a wasted spark with standard coils, or COP setup? wasted spark will be easier so may start with that.

I also got the official mileage ...... 8,706 miles...nice (y)

I have been thinking about the turbo situation along with a whole load of other ideas. The problem I've had is with the 1242 conversion, I had ages to decide what I wanted to do, how to do it, etc....with this, as it was on a spur of the moment, I haven't had time to consider what I really want.

Turbo would be nice but will cost a lots more, I'd budget 700 minimum, and to do that and have it blow would not be nice.

To turbo I'd require:

Turbo (duh) .. I'd like a water cooled one tbh
Low compression pistons ... I presume to only route I could take for this would be forged ones. (not a fan of the spacer plate)
manifold made up or modified
oil cooler

That's about it excluding all the plumbing, gaskets sets, bolts, etc.

I'd imagine the injectors would flow more than enough for the amount I'd be after.

I'd be aiming for about 120-130bhp to play it safe, but still get a lot more power out. The low down torque would be great as these are what the 16v's don't have that much of.



I had dreams of a supercharger, but its too complex, to tight and to expensive.....I'll leave that one to DaveTheTrike and his Punto (Muchos respect :D)


The other option is to get as much out naturally aspirated. Ideally I'd like to strip the head off, port, polish, get larger TB. Those would be done myself, so budget on about £150 all in and a lot of time....as long as I don't bodge it up....add in some reground cams (GSR or that other company) at about £300, or some C&B cams at about £500, and ITB, and I think it must be looking at around the 120 mark, but with peak power a lot higher up the range. Think that's achievable?


I may just see how it goes as stock though, but I know once its in, I'll never get around to taking the head off again! and it will sit as is for a long time :(


decisions, decisions, decisions......need to think more lol

Cheers,

Kristian
 
Right, poped over James100hp's tonight and removed a spitfire gear box and then headed off to the garage to do a little bit more :)

Sadly didn't have my camera, and this garage has no electric (all work done by headlights) so excuse the picture quality.

Here's where the engine is at now:

10102007.jpg

All the looms, ancillaries, manifolds etc are now removed, pretty much a bare engine.

Here's what was removed and left over :D

10102007(003).jpg


This I found interesting, and may be a neat solution for anyone doing a water cooled turbo conversion etc. Its a thermostat that will fit all the cento/punto heads, but it has the normal outlet, inbuilt thermostat, and a large and small take off for coolant pre thermostat. One is designed for the heater core as its capped off the normal hole by the manifold. I'm unsure what the smaller outlet is for, but both can be unscrewed and capped/adapted! (y)


10102007(001).jpg

Here's the engine mounting that the cento uses, hiding under the alternator/aircon bracket:

10102007(002).jpg


This poses a problem, the alternator fits to this, but the mount covers the holes, so i have to ditch the mount, the alternator, the aircon pump, the cam pulley, and then fit a cento alternator and mounting bracket. If i do this i need the 1242 16v crank pulley, or the 1008 and modify the crank sensor to sit in the correct place like on the 1242 16v conversion i did.



I am keeping the COP though, and running them in wasted spark, as it looks neater and is technically a more reliable solution.



The gaskets are metal on the head and extension if anyone cares.


Hope your all enjoying the progress! looks like I have to sell some parts to make some money for the new bits i need.


Cheers,

Kristian

If you go to turbo I would personally wait til the 1368 turbo's from fiat are available. Although to buy these would be an expensive option, if you add up all that you spend converting a n/a engine to turbo it prob works out more.

Then you know a 1368 fire t-jet has a stronger bottom end and will be reliable from the factory. A lot of the unreliabilty is brought by fitting kits to engines that are NOT turbo engines. So if your running day to day I would stick n/a for now.

Still plenty of scope for the future too, especially when you are m/s'd should be relitavley easy to set t-jet up too.

Let me know when you start the 1368 convo as i'd like to come and have a peek (mind you might give me bad ideas as well!).

It has been done before including the 6 speed gearbox & covered in some depth here. car has been running faultlessly now for some months https://www.fiatforum.com/lets-talk-fiat/91558-seicento-1-4-16v-project.html

But yes it is a nice project as it makes a nice car at the end of it :D

I read through that topic with awe, but was rude enough not to comment on it, lol.

Great job on every account and I wish I could go for a drive in it, right now. Might let me forget about my cold for a minute or two. :p In fact, I wish I could make one just like it, but we're not allowed to go that far off the wall, here. (n)

Ah that's OK, every one knows by now I'm rude, but loveable lol :)

I posted it up because I know many people missed it because its in the "lets talk fiat" section rather than in the Cento section, as many folk, & I am guilty of it myself, just read the sections relevant to there own car, or cars they are interested in and don't bother with the rest. (y)

Did that in the beginning as well, but now I've gotten used to looking through today's posts via the Quick Links in the bar on top of the page. I learn a bunch by browsing the entire forum that way.

My dad's and alfisti, my mum drive a Punto, a friend of mine has an Uno Turbo and I'm madly in love with the Coup and most all Ferraris... Oh dear, I seem to have sold my soul to the Fiat Corp. :slayer:
 
lol, its going to be months of prep, and hopefully a long weekend of swearing, cursing, and realising i don't have all the parts, then hopfully it will be in :)

I may need your help agian with the hoist at some point if possible?



I was also wondering about the box. Its 100hp, and that has 15" wheels. I have no clue at all about the ratio's, but in my logic rpm will be higher at a given speed due to the smaller rolling radius. Is that correct or is the the other way around?

Also, I'm well aware its not the first :D but will still be special, hopefully with something to make it stand out a bit ;)

The more threads on conversion, the easier it is for others which is only a good thing (y)

You have to consider the wheels to be an integrale part of the overall gearing of a car.

So putting bigger wheel son will lower the final drive, so less revs for same speed, but slower acceleration.

Hence why on Sei MPi Abarths/Shumi models they get a different gearbox with lower final drive to ensure the acceleration with 14" wheels was equal to the lesser models with 13" wheels, though we found that thsi meant that at 80mph the car sat at 4500rpm, which TBH is no good for longer runs.

With the 6 speed box from Stilo, Emmas dad Jon got the info on final drive and with tyre size worked out rpm per 1000rpm which IIRC means 80mph is now 3940sih rpm, a nice drop, means for instance on drive to Goodwood Festival of Speed this year which was about 250mile round trip we got 46mpg, and that was with me driving and not really holding back. On previous long drives with the 1.1MPi and Abarth box lucky to get mid 30's cos it didn't like sitting at high RPM, and that was with a ub 20K very healthy car.

I don't think this is same calculator as Jon used, but sure they are all a similar type thing http://www.gearboxman.co.uk/inforatios.html
 
Cheers Aaron, that could be interesting if i knew any of the gear ratios :D I know some people seem to have the info for some of the boxes, but I can't find any for this one. Maybe I'll try the Panda section, and ask around in there.

At the moment I have a standard cento box designed for 13" and it seems ok, can't remember what its doing at 80 but its under 4000rpm.

Guess most of it is just trial and error, and i will know for sure once its fitted :eek:

The price of te box wasn't to bad, £175 delivered, thats off the same engine I got so pretty much new.

I'm sure I'll have a few questions about this when i come to do it :) I know the linkages on top of the box have to be changed, and the clutch mechanism as its hydrolic, but I'm unsure about the cabin side of things!


Cheers,

Kristian
