General Hi new and fastest Siecento post

jonsei · Nov 8, 2006

Hi all, just been pointed here by fiat midland, having had a service clucth and mot done there.

Looks a great site.

I was wondering, im looking at modding my siento starting with a 1.2 conversion.

Who has the fastest siecento i think fiat midlands will be about the winner but what else have you got and is it as quick and as powerfull as there's?

The quickest that we know of is who was on the forum was wardy25s 125bhp 1.4 turbo sei, which had 18k spent on it. Does it beat that?

The most famous is the novitec 190bhp sei. Does it beat that?

I dont know how faste there's are.

They dropped me off while my car was being done in it, its a punto turbo conversion with a 1.5/1.6 bottom engine.

say it needs alot more doing, but its very fast and looks totttaly standered.

I thought punto GTS were 1.4?

Search for the novitec sei on the internet, i would think it would **** all over midland fiats....if it ever ran well (the novitec one)

Wardy 25's had an uno turbo 1.4 in it, in terms of speed the needle went off the speedometer! The novitec would eat this for breakfast as well

jonsei · Nov 8, 2006

if it run well, what do you mean?

i canrt find novotec one? link

Bushboy · Nov 8, 2006

the puntos are 1.4 as standard but you can swap it for the 1.6 sporting block or the 1.6 tipo block.

Well the novitec sei unfortuneatly was littered with mechanical problems and spent a lot of its time in the repair garage rather than doing the business on the road.

It was eventually flogged on german ebay, its not been seen or nothing has been heard about it for a while.

A shame really as it would have been an awesome car if they could have managed to iron out its problems

You wont find anything with that spelling of novitec!

The Novitek did -- or claimed -- 141.25mph, which is mini cooper s works fast. Doubt if it was geared for top speed, either.

J.R Racing · Nov 9, 2006

Apart from the Novitec car I don't think a Sei has broken 130bhp. That car was amazing but goes to show getting that power from such a small car/engine package causes serious engineering/financial issues. Would have been great for a show car only!

I have heard mixed reports about Midland Fiat but, hats off for trying that one. It seems the problem is getting a car to 100bhp or there abouts is easy enough but, getting one past 120 takes some serious doh!

I have a new project coming on my sei mpi which will be revealed soon which should be interesting even if its not the fastest engine wise.

fingers99 · Nov 9, 2006

The cheapest (non turbo) way to 100+bhp plus reliably will be a 1368 engine as detailed in a thread started by me, but with all the important stuff filled in by Aaron here . I say will be: currently they're as rare as rocking horse manure.

If anyone stumbles over one, please let me know!

a cento with a 1.4 uno / punto gt engine handles badly due to the extra weight, so i reckon if you stick the 1587cc block in there it'll be worse (unless its going in the back)

as an all round car, emms 1242 turbo sei is probably the fastest sei in this country. who cares about straight line speed if it can't corner

Only when its home made with the wrong bits, this will be used at every track event i can get it to, im sure if you see it you will understand.

J.R Racing · Nov 9, 2006

Care to elaborate, i'm with Arc on tihs one in that it will handle badly, unless you are going to modify the chassis extensively, or change the position of the engine completely.

1.4 is a handful so how will you get round the weight problem caused by the 1.6 lump.

As for mixed reports, A friend told me on a 1242 mpi conversion that you recommended bigger capacity injectors and one example was running a measly 72bhp after a 75 block conversion. You recommended larger injectors and all it needed was re-mapping which has taken it to over 90bhp - all it needed was a remap.

The stock injectors on the mpi are good for 120bhp+, trust me on this one. Why did you say this, if you are a specialist?

ON the other hand I have also heard some favourable reports so it all balances. No doubt you will have some kind of response.

blu73 · Nov 9, 2006

Not got nothing to do with being home-made.. The Cinq's and Sei's are literally to small/light to cope with the extra weight up front, its gonna have massive understeer problems, not saying your not gonna be able to pull this off, i'm just saying i wait in anticipation to see this car go round a corner fast cause i just don't think it'll be able to. Good luck with it though, and even if it does handle like crap it'll at least be hilarious and the traffic light grand prix

Ive really not got interest trying to make a response to that.

If someone comes in with a list telling us what to do, we do it. Simple

That advice was told to him by the company doing the rolling road, if you care to ask. Re-maps are not easy to get sorted in some area's so a set of injectors at 60 pounds and 20 mins to fix are generally a simpler option.

As for mpi injectors at 120 bhp, lol thats a joke, dont read everything you read. Plastic manifold, 120 bhp and 9psi makes a mess.

Exactly why i stopped using the forum, people willing to argue on the back of whats read not what they have done.

Like the good old 75 mpi head dispute.

And id like to add to that, if a customer supplys his parts and his spec exactly its down to them as to what power output is made.

You will find no problems with our work, if people arent happy with there output they should take our advice when telling us what they want, rather than relying on exagerated how to guide claims.

As for handling, its perfect, if you visit any track days etc im sure you will see for yourself. Not that i have anything to proove. Will have a glowing report in forza italia!

Oh and the 1.6 block is lighter than the 1.4. Common sense really, weigh a couple if you wish to proove us wrong.

would love to see a completed and running 1.6 turbo, i'll bring my little 1242 (once it's been rebuilt

) and we can see who can corner quicker :slayer:

on the subject of injectors.. the standard punto75 injectors - does anyone have detailed information on them, flow rates and injector opening time would be quite quite handy!
