Further update, engine bay is all clean now, and the abarth front bumper is off (will get some pics of this tomorrow), cylinder head is rebuilt and shimmed and i have a set of chrome 7 spoke 14s to be fitted when i get around to it! will be changing the tyres for 195/45/14s. Any recommendations besides conti sport contacts or uniroyals? i've heard good things about the uniroyals.

As long as they're 6J, fit Uniroyal Rainsports. They're cheaper and, for reasons only known to God (who, I suspect, designed them) suit Cinqs better than any tyre I know.

Been off work today, mainly been sitting being lazy due to feeling like crap and having no energy finally decided that i should do something, so stripped the MPi inlet manifold down to modify, clean it up and paint it. Now, I know when people have done MPi turbos in the past they have uprated the injectors, the standard punto 1242 MPi injectors are Weber IW057, 140cc@3bar, my question is do you guys think 200cc@3bar would be enough of an upgrade? As I have a set of injectors from a 1242 16v punto and these are Weber IWP045 (200cc@3bar), They are the miniture injectors, but i can get them to fit, and make brackets for the fuel rail, just the fuel rail will sit closer to the inlet manifold (due to the injectors being shorter) but i'm confident i can fit them, just don't wanna go to the effort of doing it if they're not going to be up to the job. Think I remember seeing something in DtT's charged punto thread about them being good for 130hp at the fly.
Anyway thanks in advance!

A lot depends on how you do the calculations. At 80% duty cycle the site I use says you'll need 236 - 275 cc/min to produce 120bhp.
Injector Flow Rate (cc/min) = Engine HP x BSFC x 10.5 (divided by) Number of Injectors x Injector duty cycle
where BSFC = somewhere between 0.6 to 0.7 for charged motors.
Don't have the link, but if you google for Injector Selection Guide you'll find it.
This is IWP 042 territory (as fitted, apparently, to 2 litre 16v Clios -- I'm after some in case the injectors I bought from DTT end up being too big!)

I'd Try the 045's first. I think they will be ok. With your MS, you can monitor the Duty Cycle etc of the injectors to see if your going near the limits.
You could also run a second bank of injectors and run stagged injection so under boost, or higher rev's they kick in seamlessly

OK, i think i'll try that unless i stumble across a set of suitable ones cheap. Need to get my inlet mani dipped in a decarbonising tank before i can paint it though as its really dirty inside, and all gritty have took the barb for the brake servo vacuum off (as it doesnt fit in the cinq engine bay) and once the thread is identified i'll get a plug for the hole, then drill and tap the side of the inlet mani and fit another barb to accomodate the brake servo vacuum pipe. Will be doing this manifold work before I send it to be dipped, unless anyone has any other suggestions for cleaning it?

if the dip is free,do it, otherwise petrol works wonders
OP
OP
nah dip will be about 6 quid lol but its proper dirty, probably use more than 6 quid of petrol cleaning it with todays prices! lol
Lenny
Lenny
not too bad then,did you get the head dipped as that looks as new
is it £6 a dip or is it size dependant??
is it £6 a dip or is it size dependant??
OP
OP
Yea that head was dipped and it cost 6 quid, so the inlet mani will either be 6 quid or cheaper, don't know how they scale the prices.
Any idea what they dip them in?
As to the injectors, you man as well give it a go. If it runs at more than 80% you could either up the fuel pressure or you should pick up some 2litre Renault ones for about £30.

ive borrowed a head sized dip bath cleaner thingy, was parafin or diesel filled,heated and ultrasonic. that was a while ago tho, the pro's will probs use something completely different

Yeah, twas pretty lethal though. Mind you, I can still buy spirit wipe and acetone. Anyone fancy a quick half of ether?

I remember that stuff from my science class......well, kind of, its all a bit of a blur
brake servo hole is M14 mate m14x1.25 if i remember correctly as i got a bung for mine from enginering shop and retapped a new hole on the side

im kind of in this process of pulling a turbo engine together problem is i dont know anybody or anywere that can knock me up the parts i need and i definatly cant do it myself as i dont know how to weld. ooohhh this is gonna be long and hard progress :bang: lol main thing i need right now is the manifold adapter, can anyone help me out ??
There is no manifold adaptor!:bang:
What has been done, traditionally, is to make up a plate to fit to the T15 (from, say, 8 or 10mm mild steel) and weld it onto a cut down manifold. This isn't a particularly easy welding job as you're joining two dissimilar metals.
Nor is it the best way to do it (better would be a one off tubular manifold).
It's complicated further in so far as I'm fairly sure the plate and location will differ according to which T15 you have!
Either PM richcinq, see if he has anything, or, for the first, go and find some welders/fabricators -- yellow pages -- (they'll probably use some special arc electrode), for the second, you'll need to go to someone like OJZ Engineering.
I'd avoid the SPI route and go MPI if you can.
