Tuning help 1.6 16valve turbo idea
There are quite a few, but everyones favourite seems to be sandy brown. You can find him on http://www.106rallyeforum.com/, http://www.saxperience.com/.
His prices are rather on the steep side but the work is mean't to be excellent.
Thanks

Forget the ITBs -- you won't need them unless you're going racing. Without slicks you'll have quite enough trouble getting the power down. You won't need a 6 Speed box, either. I'd forget boring the block (on turbo engines it'll often lead to the bores flexing or warping, which is really bad for power and engine life).
I'm with J333EVO on this -- in any event, you'll really struggle to make the thing handle or put the power down in a Cento.
For an exhaust mani, use schedule 40 piping -- the stuff steam and water engineers use -- available in different bends and straight sections from a supplier near you. TIG or MIG it together. Any of the better books on turbo charging will have details -- try Street Turbocharging
.
If he uses the 1.6 16v engine, there isn't any room for the standard manifold unless he wants to raise the bonnet about an inch
. Then there isn't any room for an induction :bang:.Inlet manifold curves up and over the top of the engine, then throttlebody is poking out gearbox side.
Thanks

2 weeks! Good luck but this isnt a conversion i would want to be rushing through all sorts of errors etc could occur doing a rush job

the problem with one powerfull centos, is always the grip...
but the principal problem is the more weight in the front part of the cento...
so, the limit for upgrade your cento is the engine 1368 16v...(IMPORTANT...you don't need make any modificacion for fit this engine!)
and your have more than 100 hp without turbo!!!!!
you don't need any more...!!!!
(for the grear box ok the standard from the cento, but i my oponion is better the 6 gear from the punto mk2 or mk2b)

Do some shopping around the continent and you should find all the bits you need to convert to a 6-speed 'cento without getting the hacksaw out. The box wasn't an option in the UK but it was elsewhere...
As for 100hp being enough? It certainly makes for a quick cento but there is never enough, only an excess when you don't get the front suspension geometry sorted!

If he's doing it with a Uno or Punto Tub engine, he needs (or will need)medical help! A modified single throttle body set up should be do-able (maybe reversing it to put the inlet in a better place).
But I understood he was doing a turbo job on a bored out 1.4 16v SuperFIRE.
ITBs are expensive, awkward (or some combination of the two). Dave Walker (who sells ITBs) once described them to me asa complete and utter waste of time on a turbo engine.
I was referring to the 1.6 16v found in the bravo/brava, stilo, and doblo.
Not a superfire engine.
As for itb's for turbo applications, the polish boys seem to love doing it with their BMW'S. Some silly power on stock internals. But they are big 6 cylinder engines, not tiny 4 cylinders .
Thanks

Got ITB's on my sei and it does go rather well
it isn't a turbo though...I agree with Dave Walker on this one, with forced induction there is no point whatsoever in using ITBs - a plenum is a much simpler and easier approach.
There are some interesting recent advances in exhaust tuning for turbos though and the conventional wisdom of there being no point has been thrown out the window as a result.

What size are they?

42mm bodies - straight off a Hayabusa (used to know someone who fitted the engines to cars and they regularly threw brand new sets in the bin if they couldn't sell them quick on ebay). Had to get a manifold made to fit them but it works a treat!

But they're still putting out less power than people are pretty routinely getting from Toyota and Audi motors with single TBs and much smaller capacity. The reason they're fitting the ITBs is that you can pinch them from the M series cars (seems they're a bitch to fit) -- there's a twin TB conversion avalable in the States, too. TB size isn't irrelevant here, either....
Power will become irrelevant with that tough old boat anchor -- killing the understeer and getting the power down count.
Were I looking at putting a different engine in the Cinq (I am, of course, always), the 1.4 16v Tub (as suggested by J333EVO) would be the first, and easiest choice. I'd also look at the 1.8 K Series (a very light engine which can make 300bhp if built correctly with a turbo -- BBR do it and guarantee them!) or the 1.6 Toyota mill. Any of these will require (not necessarily in this order) a rigidified chassis, rear ARB (preferably adjustable in cockpit blade type), uprated brakes (see Aaron), negative camber front end (ditto), 15" wheels (with the widest tyres you can squeeze in), LSD, anti rise front suspension. Putting 200bhp+ through the front tyres of a car designed with 50 in mind is not the work of a fortnight.
May well be easier to put the engine in the right place -- the back.
to right! as jason with hes hybrid turbo and now me with mine + rear arb/atb/stiffer chassis/decent tyres and I cant even get the power down in 4th gear once boost comes on.
not sure what power im kicking out with this but id say 150 is the absolute limit if you want a cento thats still front wheel drive and actually usable for anything other then pub talk and going in straight lines.

150bhp with traction control maybe, I've been there and the only thing it was good for was shredding tyres and that was with a decent LSD fitted and some considerable work to the chassis and front suspension too.
thats what im saying. decent suspension, good tyres, and LSD and im spinning both wheels up if I floor it in 3rd at about 30.
traction control would be near impossible to fit plus not really a fix... more of a bodge imho. your not going to launch the car any faster with 200hp and traction control then 150 without
at that point you might as well just buy a better car or change to RWD
My only option now if I want to run over 0.7bar is to let my ecu take full control of the boost so boost is much lower at lower rpms and in 1st-2nd and maybe even 3rd gear

1 week till end of 2 week deadline. How is this project going?
Mind you, that doesn't seem a bad option to me -- even with the boost chopped you have (say) 105/110 bhp to play with in a light, light, car. In higher gears you can mince just about anything.

everything going **** like always the deadline moved my mates funeral was yesterday when got told had 2 weeks so car wasnt done and its failed its mot too add to problem. engine its getting there but taking its time block come back there cant bore it any bigger than 1.4 so need to get 1.6 block now so everything is f**ked up
I'd stop right there and buy the engine J333EVO found for you.
