Anyone know what impedence fiesta xr2i 1800 side fed injectors are?

and what impedence are somethin like ermmmm, fiesta beiges?

need to fuel to about 250bhp - just for safety margin and need to know the impedence of side feds so i can make the necessary changes - problem being the existing ECU will be staying hence i need to know impedence or if a standard 130spec XR3i ECU (cos thats whats fitted to the XR2i) can take different impedence injectors if need be.....if you see what i mean


cheers

 

or is it worth running a 5th injector?

 

High Impedence I believe

Circa 12 - 16 Ohm

 

nice one thanks!


what are most injectors? 8 ohm?

 

i don't think the beiges will be good enough for 250 bhp tho mate.

 

yeh so me mate tells me - i dont htink it will reach 250bhp but wanted to be safe - apparently me mate is gonna use lancia delta integrale injectors???

not sure why he isnt gonna use some cossie ones.......

was thinkin maybe standard cossie injectors - they fuel to around 270 ish dont they? thats more than enuff - jsut want a safety margin!

 

i'm not sure whether the standard cossie ones are the correct impedence mate. i know dark greens aren't anyway. if you try to use them you'll probably find your ecu will fry. have heard but never seen anyone use lancia delta. a couple of people on here may be able to supply you with some 300+cc injectors , Stu from Motorsport developments springs to mind. but i doubt he will just supply them, it'll probably be a live map on top of supply and fitting to get the best out of them, which is a good thing but relatively expensive.

 

Reckon this is the bosch number for the 1.8. 0 280 735 503 ??

 

biege's only good for 215 max

 

interesting stuff there fellas - thanks!

its going in a budget turbo conversion and it will have a piggy back ECU you see, which im kind of ashamed to say what it will actually be lol!

hence i gotta find out what the ECU in the car already can handle n what injectors i can use in order to run it all before i turn the key with them in n *pop*

 

there's nothing wrong with doing budget conversions, just as long as you don't skimp where it's vital you have the right parts. it's false economy to put in something without knowing it's true effects and have it wipe out the engine. there are people selling chipped ecu's all the time cheaply . i have seen people claim 250+ with beiges fitted but these were only claims ( one was in either performance/fast ford mag , it was grey with mondeo rims. ) and my car runs between 220-240 with beiges, however i wouldn't push them any further than that at all. if you intend to run more power than this then i would suggest you source some injectors to cope. trouble is if your on a budget then what ones to get? how much power are you looking for?

 

not sure how much power to be honest - its gonna be a budget zetec turbo

started out life as an 1800 16v XR2i - 105ps - its now 130 spec and runs 135lbs/ft torque and 126bhp - splan is to decomp plate it up, run standard ECU with piggyback ecu to save pullin out all the loom like we did on me mates excort, T3 with escort turbo manifold, restudded head, focus RS plugs, maybe 5th injector route depending on what the word ends up being towards injectors, etc etc - it will run approx 1 bar boost - apparently tony pastie used the decomp plate method and managed 1bar all day long no probs - then he sold it and the current owner is running 17psi and has been for a while.

If it all gets a bit risky, then aquamist to keep the charge temps and engine cool - me mate has it on his series 2 running 23 psi standard comp! it did 2 standard head gaskets, so in the end we stuck a felpro on it and its been fine for over a year as a daily drive - when we took the head off, the aquamist had kept everything clean and like brand new! its unbelieveable!

 

to be honest mate you'd be better off sorting out a frst loom and putting it in, will probably make life easier in the long run, might be worth putting a parts wanted post on here or on fiestaturbo.com.
hell thinking about it you could just buy a cvh turbo lump off ebay for about £150 and then do the usual rings, bearings and seals etc and drop that in. running 1 bar you could probably keep the standard fez injectors which can be had for next to nothing , i think they can flow enough for about 180bhp.
there are so many options to take , good luck to you mate.

 

i know what you are saying matey - believe me it has all been considered - it would actually work out cheaper to buy a FRST than do any of the options to turbo it, but its me missus' car, its pretty solid n clean, and we kinda wanna turbo the zetec lump.

FRST loom n ECU aint a problem - i had a mate buy one a while back and he got his arse slapped a bit but since then we have noticed a lot of cheaper looms and ECU's etc. Might go that route yet as it may work out better as you say in the long run!
