My seicento Project

Can't really tell from those pics, but doesn't look like it.

You need to run the fuel pipe feed to t-piece one going to 2nd injector then other going to fuel pressure regulator as it has to be after of the injector its feeding, the return from the regulator then goes to the throttle body top to feed the primary injector as this is controlled by its own inbuilt regulator found inside the throttle body and normally sealed by blue wax, you can unpick this and turn clockwise to increase pressure, factory its anywhere between 0.8-1.2bar, I suggest running at 1.4bar, and 2.5bar on 2nd injector and make sure its all set up on a rolling road with someone who knows what they are doing otherwise you coudl either be very lean or very rich.

As you have it i can see a t-piece after the regulator meaning that it will not work.

I suggest that you invest in a fuel pressure gauge like the ones found here www.fuelsystem.co.uk and check all the pressures, remember to get the pressure you need to put the gauge in before the regulator to get the pressure.

Did you not transfer the old rubber dust protector and spring cover from the old shocks onto the new one? I thought they needed to be?

Also, apparently its best to move the fittings over to the new hoses, the main area of contact it on the body, behind the damper, looks like there will be lots of contact there.

Really appreciate all the pics though, really make each little update exciting lol

how do i know what bar the fuel will be running at on 2nd injector? it will be a direct feed into the 2nd injector from the fuel tank? all that the injector controller will do is open/close the injector to allow more or less fuel in?

do i use the reg to power both injectors or just the 2nd injector? or just the standard one?

the way i have it linked up is if you check the pic below which is powering both injectors at the mo can change this next time if wrong.

@ kritip

i tried to transfer them over but they had long gone and perished didnt know where sells new ones so left off

Coming along very nice, good work. Liking the intercooler keep up the good work.

The way you have all you are pressurising is the fuel from the tank to the regulator everything thereafter is not pressurised by it at all making it redundant, but by the regulator inside the throttle body.

I will explain again, the regulator only pressurises fuel before it, not after it. Imagine blowing down a straw and squeezing it smaller it would be harder to blow down as the pressure before your fingers would increase, after your fingers its no different, same principle.

So you run the fuel line direct to a T-piece before the 2nd injector and the line off the T-piece to the regulator, this will pressurise the fuel upstream of the regulator i.e the 2nd injector, the return from the regulator then goes to the throttle body where by its lower pressure is set by the inbuilt regulator, you can clearly see this in the pics of my car.

HTH, Aaron.

ah i get you now thats made it alot clearer to understand, so basically i want to just do a direct line to the 2nd injector and use the fuel reg on the standard injector as that cheers

Just thought i'd add to this as its something i've been pondering aaron, but do you think that its possible my cinq has already had the fuel pressure played with? (well not so much possible more probable?) as its gone 6 years+ of being turbo'd without a rebuild at all (touching wood by the way lol just incase!) so if it is running lean it cant be running *that* lean if you catch my drift? (like i said at pod, pretty sure its overfueling by the flames etc)

Also looked on ebay and by the looks of it a fuel pressure gauge is going to be pretty cheap to get hold of

No this is what you need to do


Alex i do not believe that VAD adjusted the fuel pressure as the was seal would have to have been removed from the pressure regulator inside the throttle body. As i said at Santa pod, even when my car was on full settings on MF2 mine still ran lean. i believe that this is the single reason why they stopped doing hi-boosts as if you got a car running fuel pressure of 0.8bar (factory set is between 0.8-1.2bar) and ran 0.6bar boost you get fuel pressure of 0.2bar i.e a dribble not a jet of fuel. This is why they capped hi-boosts to 0.5/6 bar anymore and the car would last maybe a few thousand miles if lucky, you know what happened to Alex's car.

And as you have fitted a 40mm throttle body you have increase area by 25% so have in fact leaned the fuel mixture down.

There are a few on ebay and such like this I know of one integrale owner and reporting no problems http://cgi.ebay.co.uk/Adjustable-Per...QQcmdZViewItem

will get it looked into asap either way and saw the regulator with gauge and was thinking maybe 2 birds with 1 stone kind of thing

where do you get a seicento bodykit like that from?
having struggle finding bodykits!
also aswell where can i find some decent alloys for a seicento?

i got the bodykit from ebay decent alloys for seicento...... hmmm

smoors, KN minators, khan racing, wolfrace octane, depends what kind your looking for theres loads to choose from

it was my birthday today lol package from hong kong great way to avoid tax hehe

its tiny will look great somewhere in the car (not decided yet )

Sorry, call me a prick.. but what is that thingy?

Fueling heaven

Jordan

and boost control heaven

btw if you spot another cheap boost controller gaz give me a shout

fitting t/timer at weekend if it turns up i think
