Seicento Monster Cento/ECU Master Thread

Introduction

Well starting this is well overdue although technically it's still just a car and a big pile of bits at the moment. It will come together quickly though as I have access to a commercial garage in the evenings and on weekends which belongs to a good friend. I'm lucky enough to have another good friend who is a self employed coded welder/fabricator and yet another good friend who owns a powder coating business. Myself, I do electronics so pretty much everything is covered. :D

I'm not going to go into minor details as most of it has been discussed before (especially the engine which was purchased from Gazzaman). However I will answer any questions and will go into detail with the DET 3 setup and installation as there are no UK guides I'm aware of for this.

So the car:

A 2000 SPI Seicento Abarth (probably manufactured late 1999) which replaces the silver Cinq (SPI Turbocharged) I have recently sold for restoration. The silver chap needed some TLC due to a bad repair from a rear collision before I purchased him. Someone made me an offer I couldn't refuse so I sold him on with the standard engine and pinched Mrs. Honeymonsters Sei after buying her a newer yellow ragtop replacement which I got a good deal on but wasn't really suitable for my project.

The planned spec is as follows, only thing I'm missing is the TB. Now Sorted (thanks Blu!)

I will just post some pictures of the bits for now and then intermittently as I fit them.

I do however need to keep this car mobile to park it back in my workshop so it will be done in big chunks.

Cheers
Regarding the water pipes, I would still consider routing all water upwards of the turbo, you will get more space for the air pipes, you don't see that yet perhaps, but you will. Also on a Cinq/Sei you want to save every 1 deg. of water temperature, keeping the line away from the downpipe would help with that.

Photo is not very clear, you could fit a chicken between the rad and the downpipe without cooking it. Especially once the pipe is lagged and a heat shield is fitted. As for the air pipes, they all go right so it will my make no difference I think. :)

Other hints: I managed to live my whole turbo life without the oil-pressure gauge (although I had one almost mounted, there was some problems with electrics and I gave up), what I find really necessary though is oil temperature. So you can as well get rid of the pressure sender altogether if you want to save space.

Noooooooooooo! and deny my monster gauge the satisfaction of full operation, never. :D
If needed I will just use the fitting below the turbo oil feed as I have a reducer that fits. However Desy wants to use hard lines for some of the oil pipe and insists there will be no problem with them pointing left. However we overcome it, even if it means losing the dash light my gauge will be fully functional.

From Todger's thread: Denis, a.k.a. TurboCinqy1250 ordered his custom sized low compression forged pistons for 8V from U.S. And payed considerable money for that. But that was back in 2006 I think. BTW, I wonder how is his car doing, I don't think he visits here so often anymore.

Me too, and Trickers and many of the other better turbo projects made over the years that have seemingly vanished. Do you no anything about the this beast must be on the polish forums?

I'm intriged by the manifold. :eek:

As a curiosity (now I am just keyboard happy drinking my before work coffee :D) I wonder why the t-jet pistons you quoted in Todger's thread have still such high compression ratio. They go from 9.8 to 9.5. For 300 and above powers I would expect less CR :confused: Anyhow, nice ashtrays :D

No idea I haven't looked into it yet just did a search for the brand name and that came up. Still if all goes well I would certainly consider a set of forged pistons and rods next year. That should make for a reliable 150bhp which I'm sure would be plenty in a bean can prior to some proper chassis upgrades. After that a different engine would make more sense.

Anyway it's time you found a nice clean Cento to put your engine in. All that Cento energy you have is clearly wasted. :)

I currently got extra silicone pipe and a bit of heat shield protecting it at the moment until i have chance to take bumper off again (bit of a bugger when its your daily isn't it! I not had this problem for years, i don't like it lol)

I'm sure some one spent hours in design making sure it was as hard to remove the bumper as possible. :bang:

At least you get to drive it everyday. (y)

I'm intriged by the manifold.

Indeed. The picture looks a bit scary, like the local yokels are about to drag him out and beat him to death, but the manifold I like, shows real creative thought. No turbo drain issue there! Note also the early use of the now common (in Poland, at least) bar between the "horns" .

Whose car is that, though?

I only know this car from this picture and another one with the close up of the engine bay. A manifold similar to this one now sits in Molek's t-jet Sei.
 
Seems like a bit of an engineering masterpiece even this greek drag item is fairly simple in comparisson:

I know you can get programs that calculate this type of thing. I have a friend who's well into his big 2stroke bikes and has had lots of very fancy exhaust designs fabricated in the past. I wonder if that exhaust was fabricated from such a program or someone got 4 lenghs of pipe and simply (or not!) made them fit. :worship:

It really is a far more sensible place to have the turbo in many respects and obviously has the advantages of equal lengh pipes.

Things like this seem to be more common and although similarly impressive don't seem to offer as many benefits:

Anyway last night was aborted in favour of tonight so should be an update later.
@woj is there any particular reason why you placed your EGT probe between what looks like 3 and 4?

Note also the early use of the now common (in Poland, at least) bar between the "horns" .

From chatting with various people I'm under the impression these setups when installed well are equally as strong. Must make engine access insanely easy too, however I still couldn't bring myself to do it. There's just something not right about cutting a huge chunk out of the front of your car and replacing it with a bit of tube or box section. Certainly won't be happening to monster that's for sure. :)

Yes, there is a reason for the placing of my EGT, though stupid :D I got this manifold off Mr. TurboCinqy1250 and it was already done there. Anyhow, I do not see any other reasonable place for the probe on my manifold, and getting data from inner and outer cylinder should do the trick. Worse would be just one cylinder or two inner ones, as these engines are known to have different flow on 1-4 and 2-3.
 
Room for a chicken... :D

Lamda boss fitted with the old ladys supervision...

EGT boss fitted, Pob popped down haven't seen him in ages...

Lucky I had 2 actuator brackets because I'm going to have to make one out of 2. It will be perfect after a bit of grinding and welding, there was something spooky going on here...

Actuator.jpg

I have a cunning plan for the water pipe, it doesn't look like much modification will be required after all. I'm not letting the cat out of the bag just yet, you'll have to wait and see. ;)
 
i simply cannot belive how much space altering that bracket has made... Incidently, whilst moving stuff yesterday i found one of them rad brackets :idea:

Oi that's my design and is covered by a multiple baseball bat patent. :D

On a more serious note I'll think you'll find it's more than worth the effort.

My water pipe plan has been somewhat foiled. :doh:

I was planing on making the perfect water pipe extension including the 90 and the lip. I was certain I had a few spares lying around and intended to make one from two...
However for some strange reason I have 3 spare blocks yet no spare water pipes. (n)

Now it I'll have to try and find a suitable straight length and a 90 made of steel the right thickness and has that factory look. :bang:

Ah well, you can't win them all. Looks like no more work will be done until Tuesday now. :(
 
just get some 15's dude, they'll fit! had 15s on my old cinq and sei arches are bigger i reckon. Aaron (J333EVO) ran 15's on his 1.4 16v seicento too. And with turbo power it won't be slow like my old cinq was on 15s.. And there really should be a turbo sei on ronal turbo wheels, it just makes sense!!

I know we were discussing this quite some time ago. However when going through my cento turbo archive today (as I do every once in a while for inspiration) I came across this:

Yes it's that Paradise apparently all show no go twin turbo 1.4 Sei with NOS (and a rather basic Unichip piggy back by the looks of it) from a few years back.

Anyway still looks decent on Ronals, well it would without the stickers at least, but I bet it was rubbing the paint off the arches LOL.

@puntoproject Where's my picture parts guy? :D
 
Will be up tomorrow :) had a lot on this weekend sold a fiew motorbikes and scooters nightmare now I can get to the collection of hoses what size roughly I take it main hose ?

It's not the hose but the metal pipe that bolts to the engine I'm after PP. I want to cut and shut it to the original.

If you have one great, if you don't no worries I'll just make something up. (y)

:yum: would be faster in red though i think..

No doubt about that. :D :yum:
 
Ahh whoops I thought you were on about the hose but I can get a hold of one I may have one in back of garage somewhere lol but its proberly best to mock a new one up the stock ones rust quite a bit well my punto one did I will have a gander tomorrow anyway :) after I have collected a certain fiat device :)

If you could mate, I only want about 1/3 of it. Otherwse I may even try to source a new one. It will be a much better job if I use a pipe of the exact same thickness and size.
 
mate are you needing the front water pipe for the cento to tinker?

I recently got one that came with the 1.4 block from Dan which has the cento pipe on it, but the lip of there is a slight den, you can have it for postage if that is what you looking for!
