what are the benifits of running closed loop, and what parts will i need on a 1990 4x4, is it just relevent chip and probe?

 

Give Stu a call

 

If pre cat model you'll need the relevant wiring harness for the lambda sensor aswell m8 , brilliant mod though.

 

very very good conversion i done 178miles on mine sitting at 90mph to half a tank of juice and i'm running siemens 55lb

and that included some high speed blasts against a R33 skyline

 

that sounds awesome!!

what turbo do you use now? where do the siemens 55lb injectors come in when compared with greens/greys etc?

i have a few questions but think i'll start my own post...

 

i'm using a full hybrid T35 with a 0.55 exhaust housing, the siemens injectors are mega mate the power delivery is smooth & pulls all the way to the limiter

you gotta remember Greens & Greys are an old design now probs well over 15-20 yrs old

the siemens are modern better spray pattern and good for 450bhp

I'm getting a 32psi spike and 28-29psi held and the car is so different from the the others i've driven with Greens in

I've now got a minimum 380bhp car that goes ver very well and i've gotta the piece of mind i'm not pushing my injectors to the limit

 

If it is bad that the injectors area 15-20 year old design that must mean the cossie engine is also crap!!
The injectors are MUCH older than that, but still do the job perfectly.
My car on greens goes all the way to 7300rpm in each gear too , does 34mpg sitting on motorway, around 28 little runs.
As for pushing the limits of the injectors, you just go up a size.
I only have at the moment 330bhp, (330lbft,from2200rpm all the way to 6500rpm) but at 1.4 BAR.
As the siemens seem a newer design they should be better, oh I DON'T have closed loop on mine.

you don't half post some utter wank, there is no mention that Greens are a bad injector, no mention that cossie engines are crap, jesus get back to topic in question and get off your high-chair

 

Im with silky on this one

in one hand i have a 20 year old injector with old technology.

In the other i have a modern day injector without a major difference in price.

You would be to choose greens over siemens injectors

Its only my personal opinion.

and when you say the cosworth engine must be rubbish aswell. Since the cosworth engine was built there have been many modifications to enable it to cope with more power and to make it stronger in one way or another . You cant modify a Green injector, If you could i would be going for 8 Modified spray pattern and impendance green injectors in my car.

Sorry but i have witnessed a lot of different arguments on the forums fueled by one person in paticular and have not interviened but i feel quite strongly about this one so i have.

 

I'm changing from 803's and t34.48 to 55lb blacks and t34.63 and only heard good things about the blacks.

 

The point missed here by some dummies was that just because a design is old does not mean inferior, and the bit about cossie engines was called sarcasm.
Cosworth did such a wondefully good job that the engines were having head gaskets changed when undergoing NCH test at southamton uni on std power, NOT raised power levels.
The main changes as ever was due to a shit design of cooling system, the reason it changed on subsequent versions, nothing to do with power at all, the changes were what they should have done to start with.

i have owned 3 saphire cosworths now and in a way they are shit
we spend thousands on them every year just for them to go wrong

BUT and i mean BIG BUT...

they make us all happy put big smiles on all our faces

everyone is a little bit different and in our own little way we love them

who give a flying fuck IF GREENS OR GREYS ARE OLD OR NOT why start an argument over it we all go on here to chatt and be frendly
just remember that

wake love not war

 

Couldent agree more mate

Other than the bit where you say cossies are shit

it is like an endless pit of money... im on my 4th one now and ive mainly always had fords.

Problem is once you start you never seem to stop, its the whole competition side i suppose i think everyone just wants the best they can afford and different people will always have different views.

no need to argue about it

 

yep spot on didnt really mean they are shit far from it just an expression

love the cosworth

if people want an argument fuck off somewhere else

 

Hand that man a medal

 

Is there any internal mods needed for L8 "red" ECU other than "green" chip when going to closed loop?

 

Roosie did this with his 4x4 - he found the plug for the sensor was already present, it was just tied back out of the way. All he had was the chip and used another ECU - don't know what type though, and obviously screwed a sensor into the downpipe.
