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
OK things are going to start moving again this weekend, I might just fit the engine and box minus turbo as I haven't worked out exactly which boost pipes I need yet to mate up to the GT intercooler yet. I was going to buy a generic kit but none of them contained the 90 silicone elbows and numerous other parts I need, but have plenty of stuff I don't so it wasn't worth while. Anyway I forgot to mention one essential accessory in my spec list...

The Monster Cento Key ring, what serious turbo fan could be with out one of these. :D

Dammit, just been dry fitting some of the parts together in preperation for tomorrow, or should I say later today. I've realised I haven't got any bolts long enough to go through the throttle body in to the manifold. Hopefully I can source a couple or maybe just some lenghs of threaded rod as temporary measure today. Due to the larger spacer they need to be about 20mm longer than the standard cento items. :bang:

Will use the 75 injectors for now until I fit the turbo, might hook the standalone fueling up if I get time then do a quick rich map otherwise I'll just splice in to the original injector wiring and tweek the fuel pressure if I run out of time.

I'm expecting a few issues to slow me down, I just don't know what they are yet. :)

It is a bit easier to do it with the bumber off

Not really when you have a ramp, doesn't need to come off only when only the engine and box are being fitted, it's just another thing that needs to be put back on. :)

Well I nearly have a Seicento 75 minus the fancy manifold :devil:, as expected didn't quite go as smoothly as I would like. Little anoying things costing lots of time.

Hopefully will have it on the road again tomorrow.

Following things caused me problems:

Brake servo pipe ( I knew about this too but forgot. :doh:)

TB bolts (had to use some threaded rod in the end, spent half the day trying to get some).

Cinq box has different mount holes so we had to remove the ATB diff and put it in the Sei one, at least for now I'll probably swap the casing over.

Fuel lines/fittings (need to sort this out tomorrow).

Rear gearbox poly kit didn't fit the mount on the car but after a bit of head scratching one of the chaps who was helping me realised it fitted a different brand new mount I had. Same part number but slightly different. :confused:

Had to weld a bit on the standard down pipe to extend it a bit (thanks Dave :)).

Had to remove a lot of the bits for the turbo install, which will have to be fitted again in a weeks time. :bang:

Few pipes need extending.

Various other small annoying time wasting issues but nothing too serious.

Should be on the road again tomorrow taken the day off to sort these things out. :)

Thankfully the chaps got stuck in and gave me a hand with the more awkward bits where I would really have struggled on my own. :)

I know you are not there yet with the turbo, but the water going through the TB should be bypassed. For a turbo you really do not want to heat up the TB and that is what this water connection is for (y)
 
Tis alive :D :slayer:

After finishing off all the annoying little bits and pieces and priming the oil pump it sprang to life first turn of the key. Tick over isn't great cold and even worse when warm, no doubt fueling just needs some tweeking.

Revs nice and clean with a purposeful rasp, test drive after some adjustments tomorrow. (y)
 
Good progress mate (y) Remind me, this a P75 engine run by 16F ECU? IIRC this setup makes it run a bit too rich. Also, the CR is lowered, right? This does not make things better for the running.

So, when is the turbo being dropped in?
 
Maybe this weekend but more likely the following weekend as I could really do with a rest.

Next steps will be oil cooler, intercooler and turbo. :)

I might go to standalone fueling before then, all I have to do is swap 2 cables. :D

Edit:

Yes 16v pistons 1.1 ECU 75 engine.

Well even reducing the fueling silly amounts the injector pulse width is just too long for mpi on the standard 1.1 ecu. Any lower and the spray pattern, or indeed spray will be completely compromised so I'll need to connect up the stand alone fueling to get anything below 1500rpm to work properly. Connection is quite literally a 5min job however the battery on my laptop has died so we would need a very long extension lead (a few miles at least). :bang:

I could alter the wiring and use the DET as an interceptor but it's really not worth the effort for such a short amount of time.

I have ordered a replacement battery so can't do much else until that turns up. Still I took it for a quick ripp around the block and it's very pokey for a low compression 1.2, much better all round than the tired 1.1 it has replaced. (y)

The full set of strongflex engine mounts is ridiculously solid by the way, not a bad thing since the 75 inlet is obscenely tight but even with the red supposedly softer items quite often it feels like you're experiencing a mini earth quake.

Just going to do little bits and pieces this weekend I think need to spend a bit of time with Mrs. Honeymonster and also fit the remote central locking I promised I'd do months ago. :)

Also I could do with a standard bolt on diff ring gear if any one has one spare as I noticed a chipped tooth when we went to install it for the third time on Sunday. It's only a tiny chip but I'm very fussy and it's causing me sleepless nights. :D

ring gear as in speed pick up ? if so i have one :)

No it's the cog that goes around the diff but thanks anyway mate (it needs to be bolt on, I have about 5 pressed on types). (y)

can you get some pictures on the inlet mani fitted please.. In particular
passenger side of car, thinking i might have to dispose of all the ABS gubbins
on mine to fit it in.

Yeah no worries mate I'll grab some next time I head up to the work shop. The brake servo connection has to be moved to, I'll get a picture of that aswell. :)
