Seicento "Grey Matter" - finally back in a Sei!

Introduction

Hi! My name's Jesper and I live in Odense, Denmark. 33 years old and I've been hanging around in here since 2006, mainly lurking in the shadows.

Back in 2005 I bought a money pit of a Sei and now I've gone and bought myself one, again. Same colour, different everything apart from the money pit detail.
I couldn't resist when I got this offer from a acquaintance of mine whom I got to know when I had my first Seicento. He's a good man - I think he just lost his patience and reprioritised to focus on his family and business rather than pouring funds into something which will only depreciate further.

More photos will come at a later point, so this is merely an introduction. CBA to was and polish it, yet - too much mechanical stuff needs to be done.

The engine and gearbox have done 99.600km at this point and nothing apart from brakes, cooler and a few cables has been done, mechanically since 1999 and it has only been driven occasionally three Winters.
Underseal was done years ago and will be done again before I store it for the coming Winter.

The following changes has been made by the previous owner:

Rear arches rolled (proper job)
Yellow Koni shocks
60/40 lowering kit (KAW and Ventura)
6.5x15 ET32 Barchetta steelies @ 15mm spacers with Nankang 165/45 :yuck:
Debadged front and rear + poor job of covering the boot lock :rolleyes:
J&R pod filter (n)
280 degree C&B cam :devil:
Head ported and skimmed
Different inlet manifold
Custom 2" exhaust (loud li'l' bugger)
Gas bonnet struts
Supersprint exhaust manifold
Bosch chip

It also had quite massive custom skirts and bumpers with Smoor wheels, all of which was sold at some point. I'm not allowed to copy photos from the site, so you'll have to live with a link to the profile at "bilgalleri.dk"

http://www.bilgalleri.dk/galleri/1450-fiat_seicento

Interior:

Custom leather/green alcantara with yellow stichings
6.5" speakers in the parcel shelf (but why? :confused: Can't hear'em anyway!)

In the deal I managed to score his NOS 14" Abarth wheels which will be fitted at some point. I will likely go for 165/55-14 as they are road legal (+4,73% circumference of 165/55-13) and a lot cheaper than 175/50-14. Possibly a bit more comfortable as well and they should fill out the arches nicely.


What needs work:

Likely the clutch and cable, beforelong
Paint falling off on the left, front wing
Fronts discs and pads
Stock air filter case with some mods
Different exhaust (CSC or whatever I find with a good price/quality ratio)
40mm TB
New headlights (on their way)
-35mm H&R springs (maybe - prev. owner lost the papers on the existing springs)
New strut mounts (so might as well change the springs)
Likely every suspension bush on the car, lol
Fluids change
Cambelt, tensioner, waterpump and refitting a cambelt cover
Rubber side strip for the left side of the car.
Paint my set of Abarth skirts and fit them if I ever find an Abarth roof/rear spoiler.

There used to be a 40mm TB on the car, but Tricker turned up the fuel regulator and at some point it started having a heavy smell of petrol inside the car. At first, the remapped chip was replaced with the Bosch one (I still have the remapped chip). As this made no difference, a stock TB was fitted and the 40mm one was binned/sold.
I hope a 40mm TB with an untouched regulator will work out with the remapped chip as the engine was pushing past 85BHP in its time.

I want a "sleeper" car which runs faster than it looks, drawing as little attention as possible until I floor the throttle! :yum:


Idle is sort of lumpy once the engine gets up to temperature. A stop/start of a thoroughly warmed up engine has it idling on the verge of stalling.
I'm contemplating giving it an ECU reset as per: https://www.fiatforum.com/cinquecento-seicento-guides/94040-how-change-ecu-chip.html
TB fitted!
FPR adjusted!
Idle screw adjusted!

On the first startup the idle was all over the place but finally settled around 500rpm and a reset made no difference. Blocked off the idle intake and turned the screw till idle was semi-steady at 500rpm and reopened the idle inlet. Idle is now <900rpm once the engine is warm.

Went for a drive and the engine was running very lean. Had to feather the accelerator to go anywhere and the plugs were too clean e.g. no carbon anywhere! :shock:
FPR screw was given half a turn at a time and it ended up at 1 3/4 turns in. Carbon is slowly building up in 'the bottom of the plugs' and has a nice, light brown colour.

After these adjustments the car pulls from 50kph in 5th gear like a stock 1108 would. It'll keep a steady 80kph in 5th as well. Neither were an option before and I was forced to do 90kph or more to stay in 5th! 50kph meant 4th gear, tops.
0-100kph is very close to 10sec which is a whopping 2sec faster than before and the rev limiter is literally annoying in 1st and 2nd gear.
Acceleration beyond 110kph is amazing, considering the engine's size.

No, it's not as quick as a high-boost turbo, nor was I expecting it to be so. It's every bit as nippy as a stock Cento, though, except there is as much power as there is noise coming from the engine, once the needle passes 4.5000rpm.
There is absolutely no doubt in my mind it'll hit the limiter in 5th gear, even if it is raised to 7.500rpm.

Alas, there is oil on plug no. three... and the engine isn't thoroughly stable at idle speed, either. As there is white goo in the coolant, oil level is NOT rising and the engine purrs along freely at higher rpm, I REALLY HOPE it is only a dead head gasket!

If it turns out to be worse than that, the car will be sold or scrapped. Engine swap is simply not an option for me as I literally don't have anywhere to do the work other than pay a garage for the job. On the other hand... why not get it bored to fit 1242 pistons, then?

Oh God... this is likely to turn out expensive... HAH! *Fade in Queen's Bohemian Rhapsody*
 
I'll be fitting the Abarth wheels with 175/50 or 165/55 profile, depending which of them my normal tire-guy is most desperate to get rid off, lol! He sounded really (wheely?) surprised when I called him and stated the size of the wheels. He didn't quite get why I don't want 195/45 like most people, till I mentioned they'd likely handle and look weird on a 5.5x14 rim.

"We haven't sold tires in those sizes for like 10 years!"

Well, duh! :p Find 'em, fit'em, gimme the bill! :devil:
 
Attempted to start the car today and it didn't fire up. "Oh grief, the Fiat Curse shows its face again," was my first thought.
Got under the car and removed as much sticky oil and dirt from the crank position sensor as there was room for. Didn't help at all, but hey then it's done.
Pulled first the fuel feed and then the return hose from the TB. Both squirted fuel so pump and likely CPS was ruled out.
That got me thinking the injector had given up, so I fit another I had...

WROOOOOM! :D

Might get rid of the Barchetta wheels tomorrow in exchange for a set of 13" Sporting ones and a bit of cash my way. Mehehe!

The tire guy ran into "delivery problems" so the Abarth wheels are still on hold. :sad:

Picked up the rest of the goodies that came with the car:

Stock cam
New cat
New alternator/generator
Abarth sideskirts (black, though)
Stock inlet manifold
Rubber strip for the left side of the car

Since the skirts are black and the front left wing is rusty, I am considering just painting the lower ~60mm part of the entire car black, as well. Just a thought, though.

Inspected the underside of the car and there is literally no rust! :D
Exhaust is a bit weird. 50mm pipe welded to the 38mm pipe coming off the cat. I'm inclined to build a new exhaust system. 44mm should suffice and be a bit more quiet. The stock 38mm (including CSC, Supersprint etc.) seems like money out the window compared to a bunch of pipes, bends and mufflers.

185/50/14 are possible. Conti Sport, etc.
 
185/50/14 are possible. Conti Sport, etc.

And beyond the 5% I am allowed to increase tire circumference from 165/55-13.
I'd rather not describe this country's legislators in adequately colourful terms.

If the tires I've ordered aren't on their way come Monday, I may have found a good offer on some 165/55R14 Bridgestone Potenza RE030 at €81 a corner.
Or screw the rules and get a proper size instead, of course. Kind of feels like I'm forced to pick between old or low quality tires.

But oh, how I think I'd really (wheely?) like the Yokohama A539 in 185/50R14. Think they look sooooo good! :yum:
 
Never said I was easy to deal with, btw. Sorry! :bang: Ahhh :p Still appreciate your input.

Should I not care for the Abarth setup I can always sell and replace them with something better and maybe lighter? Always found OZ suit the 'centos well and 6x14 opens up a whole new range of tires.
 
6x-whatever ET24 or greater is legal.
195/45R14 and 195/40R15 are both legal as well.

That leaves me with some good tires and rims to choose from, all things being equal and with a bit of patience anything's possible.

My first Sei was fitted with 195/45 on 6x14 Punto rims. Couldn't have asked for better grip whether cornering or braking which was a good thing considering my complete lack of experience at the time! It stopped on a dime and would shoot through roundabouts like nothing else... kind of makes me wonder what the heck I'm doing, sacrificing that over a set of snotty, 5.5" wide rims! :chin:

Quit messing with my head! :p


What it boils down to is what a given MOT man will accept and officially approve. Do everything right and it is technically not a problem to get your modifications declared in the car's papers.
Everything goes pearshaped once you cross an undefined line where the car's identity is changed. And that part I know too little about. :)
 
Got rid of the Barchetta/Nankang setup last weekend. Traded the wheels for a set of 13" Sportings + sufficient cash to finance a set of brand new Hankook Winter 441's with a 155/65 profile as opposed to the 155/70 worn and battered mix of tires already fitted. Rims are not in great shape but good enough for winter use.

Oh, what a joy to have fresh, properly balanced wheels fitted that don't make the car jump every time you're near a white line or a pebble! :D Total cost was just shy of €5.
Just need to give the Sporting rims a proper clean and maybe later paint them some awful colour just for kicks.

This is in fact a rather good profile. Less bouncy and with feedback enough through the steering wheel to make me feel in good control. Added a set of 10mm spacers in front - legal or not, it just feels better. Besides, theres no point in having them on a shelf somewhere and they can always be ditched for a few hours, come MOT.

Still waiting for the tires for the Abarth wheels.

As the car ended up om a lift for the tire change I got under it for a proper visual inspection. Definetely 100% rust free apart from a bit on the surface of the lift points. Sweet!

ARB bushes are shot, springs are beginning to rust and front brakes are sticking slightly but other than that all's good. So, a good cleaning of the brakes, a set of ARB bushes and a set of new springs incl. strut mounts in the near future should suffice. Not bad, really.

Cambelt and tensioner has been ordered along with a few other bits.

I'm attempting to drive like a nun to find out what city driving mileage can be as opposed to what it's been like so far. The trouble with the C&B 280/268 cam is that it's soooooo muuuch fuuuuun going through the revs. Add to that the motorcycle-like note from the 2" exhaust system and a panel filter breathing through a sawed-off front part of a filter box... head turner! And old people hate me. :eek:
 
This topic needs more photos :)

You have a point. My bad, really. I always get caught up in the planning, buying stuff and working that I forget taking photos. :eek:

Will mend this once there'ssome real progress. Fitting Winter wheels isn't progress to me... getting the car cleaned up for a photo shoot would be! Too bad I' working throughout yet another weekend. :rolleyes: Money's good, though.
 
Had a short yet inspiring conversation with a couple of colleagues at work, yesterday.

A few weeks back one of them mentioned I should consider fitting a set of throttle bodies. "It's not rocket science, you know!" was the overall theme.

Just for laughs I mentioned an extra inlet mani came with the car to which the other guy responded, "I have a set of 38mm throttle bodies with injectors I was going to throw in the bin. They're all fine but I won't need'em now I've gone turbo on my ol' Kadett."
Within five minutes the two blokes had decided it's an easy job to just stick them on with a bit of cutting, welding and rewiring a few bits just to see what'll happen. I wasn't really a part of the conversation - absolutely clueless TBH. :confused: That just makes it fun!

One's upgrading his Volvo 142 dragster with a Supra engine, working to push it beyond 600BHP. His ~440BHP B23-engine isn't good enough. As a part of his hobby a dyno became useful... so he built one.
I'm still reading up on the basics of 4-stroke tuning, so I can't really say that much. Just want it to work, lol!


Worst case scenario:

Stock ECU goes nuts with ITBs and I'll be looking at a stand-alone setup. DET3 seems appealing.

Decision time: August.
 
I've been told that if we put a Punto 75 camshaft and TB it will do magic :D
Im planing on do that to mine, and a ecu chip. Just the camshaft itself should give around 7\8bhp :cool:

Considering my engine's got a much hotter cam (Comombo & Bariani 280/268) fitted an 866-cam would be a downgrade. :) I just don't fancy doing a 0-110 video as 1st gear is too short. I'll admit it's in dire need of a remap but that's the last thing on my to-do list.


Took a photo from the side, today. Once I get the car jacked up to fit the cambelt and other stuff I'll take a few photos of the exhaust.

Stock air filter box fitted today, hoses and all.

Power difference compared to a sucky cone filter? According to my SOTP Dyno, none.

Noise difference? Silly, lol!

The cold air feed will be altered, though. The hole will be widened and a flange will be fitted to accomodate a 50mm hose, instead.

Absolutely no photos, lol.


Really want to do a turbo build... can propably source a 1242 16V at absolutely no cost, which is quite appealing. This is a future 'maybe' project - merely a thought, so far.
 
Hit yet another brick wall as I decided to dig a bit deeper to get a hang of what I'm allowed to do. Turbo is likely out of the question unless I dig up a genuine Novitec kit - need proper emission data. No chance in hell I can make a custom setup and get any sort of approval, lol! Well, unless paying more for a piece of paper than the car's worth, that is.

Had the Summer tires fitted on the Abarth wheels yesterday. Bolts weren't long enough to fit spacers (well, duh! Brain fart!) and without spacers the tire catches the anti-roll bar on full lock.
Refitted the Winter setup for now but the tire guy stripped the threads on one of the wheel bolts, so they're supplying me with a new set today. The hub threads were not damaged!

Finding longer wheel bolts locally with M12x1.25 thread turned out to be impossible. I found one set in the other end of the country. 5-9 days delivery and a total cost of €70 for eight frickin' bolts!
I am now waiting for a set of 16 (M12x1.25x40, 10.9) to arrive from Germany, which cost me €29, total. We'll see whether they're really 10.9 grade, of course, but here's hoping.


As for the Summer setup it is temporary. The tires are Ovation VI-682 165/55 which is a Chinese brand. They're not meant for going nuts on the windy roads. Nor is the car till I'm satisfied with the suspension, brakes and engine. I'm on the lookout for the right set of rims (6x14 195/45 or 6x15 175/50) but till then I'll be happy with the Abarth alloys and knowing the tires are el cheapo I'll have to restrain myself.
Since the Abarth rims are in great condition and the tires are legal it shouldn't be a problem selling them and not lose a penny.

Found a loophole as far as spacers go. H&R DRA kits along with the rules allowing me to increase track by a total of 20mm gives me heaps of options as compared to before. Just have to do the math!

More photos will come but I have little spare time. I work, eat and sleep till some time Saturday evening and have plenty of plans Sunday. Four weeks off work from next week, though. Can't wait! Neither can the car! :p
 
And here the tiny one is on the Abarth rims - looks really good methinks! But me also thinks nothing's anywhere near the charm of the Abarth rims! ;) Forgot to fit the yellow, Abarth centre caps. :eek:

Gives an impression of how low these springs are and to say the ride is hard is like calling the Pacific Ocean 'damp' :p

I'm looking at switching to a ST 40/30 setup, instead. I was seriously considering H&R 35/35 for a while, but it seems these are only made for the non-Sporting models. :confused: A ~15mm drop from stock Sporting seems silly. On the other hand, I'm building a sleeper... ARGH! Decisions!

Fresh wheel bolts all around, 40mm long. Had to shorten the rear ones about 2mm. Spacers... spacers... really want spacers but can't justify a set this year, but will likely end up widening the track 50mm in front (2x25mm spacers) and 30mm rear. Purely for looks, to be honest.

Major difference in turn-in and steering response going from the 155/65R13 to 165/55R14. Still very nippy and it's now necessary to put an effort into activating the ABS as opposed to the both taller and narrower Winter-compound.
These Chinese tires are quite good and grippy, it seems. On the other hand the temperature is constantly over 22C at the moment, so we'll see. When neutral on the throttle they're not very noisy, but under hard braking or acceleration they emit sort of a whine, though far from as annoying as the Winter setup.


Fitted new exhaust mounts and spent most of the day attempting to get the black door list to stick. I'd found some clear no-more-nails-sort of stuff which turns out won't bond to anything at all. Dug out some other stuff which needs 24 hours to harden so the duct tape isn't there for looks - on the other hand, it's a Fiat! :eek:


Gave the fuel regulator another twist and lost nothing down low but gained a tiny bit on WOT from 4.000rpm. All good, very close to ideal I think but I'll find out once I get a wideband in the exhaust.
