photo taken from the gallery on here ill get some more up soon. not nessecerialy in the right order just what i remember

The story started back when i was 17 (now 21) when i had my first cento an 899 had far too much fun in it. Brought a second 899 for £30 did the HG then sold it.Then brought a new car and cento no1 sat on my drive looking very sad. Fast forward to the beginning of last year and i spotted an ad on here for a cento shell needed so i offer her up and swapped for my 3rd cinq a crashed yellow sporting from purf. i only was going to use parts for my now deceased 126. part of the swap also included a set of wheels and some other parts. stripped cento no3 to a shell learning a lot about how they go togeather faults etc and most importantly collecting a big pile of parts, bolts, clips i kept everything.

Of course i could never be cento-less so spotted on ebay cento no4. described as needing a new engine (big ends gone) but having some new bits and a new set of tyres. Brought unseen but it seems i did well. The big ends turns out to be only an alternator (which i had). Did the handbrake with parts i already had, lowered with new shocks and using springs off cento no3 (40mm lower), insured for a rediculous ammount and drove it around relighting my enthusiasm for these cars. once tax and mot was up there were a few problems that needed sorting so it came off the road for a rebuild.

i needed more power and this came in the from of a 1242 8v that i removed in the rain from an x reg punto (mpi setup). this turned out to have HG faliure and had never been serviced came complete with treacle oil which stank and needed old engine oil to flush it out (wouldnt move at all). I ported and polished the head from cento no3. Got the flywheel lightened and balanced with the crank assembly (4kg), put a 866 cam in and cleaned, painted replaced as much as i could.

It was the cars turn next first was the rear. I removed everything stripped, painted with new poly bushes. I read on the forum about rear ARB and decided I had to have one so MGF bar order for £15. I cut out the centre section and welded the two halves together. I made up some plates to weld onto the lower shock mounts. To mount to the rear beam I used standard outer ARB brackets and welded them upside down so the open side faces out. The exhaust hanger was cut of and a new one from an old back box was welded on. The drop links were made from a piece of flat bar as i decided adjustables were not needed and the same bar was used to close the brackets on the beam. It all bolted up with front strong flex ARB used. The tank mountings were retapped for bigger bolts. The tank itself was bare metalled then painted although this turned out to be a waste of time. New brake lines were run. I then turned my attention to painting the underside while it was all off paying close attention to the inner rear arches. The whole rear was reassembled. I made a new number bracket and used a nos one that came of cento no3.

hope these explain how it all works

rear end

I then turned my attention to the front. The little 1108 was removed, ancillaries swapped to the new engine and the gearbox cleaned. The bay was cleaned and in places repainted. I put in a new rad and tested the fan and switch. The front arms were polybushed as was the ARB I made a new ARB bracket as the old one wasn't good. The ballpoint gaiters were sourced from a Massey ferguson tractor of all places brought on a whim at a local show. The shocks were treated to new top mounts. New brake lines weren't needed at the front so the brakes were cleaned and new pads and disks were put on from cento no3. The engine and gearbox mounts were polybushed with strong flex inserts. Like the rear the underside was repainted. Then it was all bolted in, the exhaust was fettled for the extra height.

The interior was next. I removed all the rear excluding the door cards. I then tracked down a pair of seats from an mx5 collected them. To mount I had modify the runners and then fabricated some mounts from box section which the seat bolts to and then bolts to the floor using the original mounting points. For front seatbelts I used the rear fabric stalks bolted to the floor. The carpet was removed scrubbed and the underfloor material removed the carpet was then replaced. Since I was now sitting a lot lower the steering column was lowered with spacers made from solid bar. The gear stick was also shortened. The handbrake came out of my 126 as it was slightly shorter than the cento on. The steering wheel was a bit more involved. This came from my 126 but had a different spline so I removed that one very carefully and welded in a cento one I had I then used the horn push from the 126 although I do have an 899 one that I can switch it to.

8 months after I started I Moted tax etc after a few hiccups. It was worth it the car corners flat the turn in is amazing serious grin factor inducing. The interior turns out to be the best mod ever sitting with my shoulders level with the window bottoms the wheel straight into my hands no aches or pains anymore.

Enter the abarth bumpers found at my local scrappy prised out of their hands with one side skirt the other had gone AWOL and the spoiler was destroyed all mine for £30 these are yet to be fitted and are being prepped

It quickly became apparent that I was burning oil a quick thought appeared that I had snagged the stem seals when fitting so head removed a week before Stanford hall and cento no3 head was put on but when doing so I noticed that the pistons had lots of play in their bores not good how I never noticed it I do not know. So I slung it back together turning my attention to more important matters wheels. The wheels puff had given me were some revo rfx 13x6 in 4x98 fitment. So 15mm spacers ordered. Now with days to go to Stanford they needed painting so grabbed some yellow metal paint that I had slapped that on and got them fitted.

Stanford arrived the journey was good comfortable only issue was stalling at junctions and using lots of oil using 4.5 litres for 320 miles not good at all something needs to be done an abarth spoiler was collected from whitz

Up to date pics to follow and more soon
Lots to update suspension all sorted incl the new design arb. It's been fully wax oiled in all the cavities. All the bay has been smoothed and painted only with a brush but it looks all right.

Slight change of plans I've decided to go back to 8v got a 1.2 8v lump to build up properly and use my det3 to control it maybe even put an angry snail on it a bit later in time.
 
Been reading through quite a few of these project logs and there fantastic. In a few weeks, when I next get paid, my cinq' is getting some well needed love and these logs are fantastic inspiration :) Just need to learn how to weld first :/

Let me know if you need any welding help in sure I can give you some pointers if you live anywhere near me id happily show you around a mig/tig welder

Thanks but I'm at Huddersfield otherwise id take you up on the offer.

Got a friend who's restoring a MK1 Golf. He doesn't know it yet but he's going to show me :). Going to start on a few projects before the car. Building an engine stand and crane for the little Fiat, idea being similar to taking someone round a car park before their first driving lesson.
 
Lots to update all mechanicals have been redone so everything is new bay and underneath is all painted suspension specs are

Front

Sei pas rack
Sei pas top mounts
Bilstein shocks with apex 30mm springs
Red polybushes

Rear

20mm arb running through the beam
Red polybushes
Bilstein shocks with apex 30mm springs

I'm slowly thinking about using this for hillclimbing so cage,buckets,harnesses and a high spec 1108 na

Possible engine specs
1.1 block
1.2 Pistons and rods balanced
Lightened fly with balanced crank
Mpi head (or 16v head?)
P75 inlet with 16v TB (or 16v)
Closed in ram air induction kit
Decent cam currently looking at the formula 750 control cam which looks to be 260 duration but comes with uprated valve springs
DET 3 to control it all

I've started the engine build all Pistons and rods weight matched. I've started to port the head opening up the chambers a bit
 
All brake lines redone in kunifer and braided lines all p clipped every 100mm or so. Fuel lines redone in copper again p clipped every 100mm. New master cylinder as well

Cylinder head not yet finished waiting for some flap wheels to continue to a slightly higher grit. Valves all clean and polished undercut the stems slightly on inlet side

Now onto the pics

Forgot to add I've also covered the brake lines and fuel lines in thin Ali riveted over to protect it all.

Cheers slowly getting there (it's now rolling almost) plan is get it driving with engine in and loom then in spring I'll respray it and finish putting interior in

You can have one just need to get me a beam and arms down here

Loving the update mate :)

Indeed, this is the same cam I've got. It's set to go in next weekend, if you're interested in the results? Good pricing, only took 5 days to get here too. Valve springs are nice too!

Defo let me know been trying to find specs on it I know springs are longer and shotpeened and it's either 260-270 duration can't find much else on it and it's a very good price I've found cat cams start around 250 mark. One thing I've read is that the pulley bolt is 3/8th unf
 
Then I turned my attention to the engine. Pulled it out of a rotten cinq that's here I mounted it onto my homemade engine stand

On the surface it looks a bad engine and it didn't run right so I feared a full rebuild car had done 75k but judging by th a frame attachment points on the front slam Pannel and the trailer lighting socket in the engine bay it seems to have spent much of its life either behind a Motörhome of sitting on a drive so the internals look like this.

image3156.jpg


image3158.jpg


Amazing condition no wear on the bores cross hatching very present little oil staining of internals also has the blobs of paint on the caps to show what bearings are fitted

So plan is to whip the Pistons out weight match them the reinstall I'll do all the seals and core plugs.

I've also decided to use the head on this engine. It's the 108 head which according to the 750 lot flows the best. It also has nice round inlet ports which I've read is the best shape also means fairly easy construction of my new inlet mani which I'll start making once the engine is in place I've started to calculate a few bits such as plenum volume.

Also noticed that the ps spring is touching the body the ds is fine is it down to the top mounts or incorrect installation?

So update I've purchased a c&b 268/250 duration cam and vernier pulley off someone on Facebook also got manual window winders coming to loose some weight there and hassle of leccy windows.

I've also started rough calculations of the new inlet manifold I'm using this calculator. http://http://www.exx.se/techinfo/runners/runners.html

So results are as follows

31mm runner diameter
274mm long from valve seat to plenum

Seat to port face 85mm ish

Runner length

189mm from face of head to plenum

Target peak power 6200

Still need to check this manually to ensure accuracy. The plenum will be out of 3" tube or if I can get it in this country d shape extrusion and needs to be roughly 1-1.5 times engine capacity. I'll use a 40mm 16v tb mounted on the end opposite to the timing side this will be fed by a closed induction setup

Lots to update

First up my c&b cam and homemade vernier came just need to remove the lumps on the outside of the pulley

image3162.jpg


Over Xmas I decided to remove the bonnet catch completely from the car and beef up where the spring catches will go. Ended up having to cut away a bit of the slam pannel and remake part of the top lip
image3170.jpg


image3172.jpg

image3174.jpg


Beefed up spring catch mounting points with 1.2 sheet

On New Years day had a nice trip to Carmarthen to pick these up from Huwbishop unsure if they'll go on this or another cinq I have here

image3169.jpg


Done this to a bonnet incl cutting slots in it and some holes in the support frame for weight reduction

image3173.jpg


Will be reclad in 1mm Ali once it's all sprayed rust out of it etc also done weight reduction to the doors more to do on them and tailgate will be next for weight reduction. I'm aiming for each pannel to almost halve in weight. So hoping total weight of car with a cage to be sub 700kg

Head is all ported to be taken to engineers next week Pistons have also been weight matched ready to be reinstalled

And today managed to get it off stands onto all fours and rolled out for the first time in about 1yr slowly getting there
