loom nearly finished


cps fitted


nearley there



new fuel feed pipe


a bit of paint and its done





just the rusty arch to do now

 

cant beat the efi

 

engine bay looking sweet, there's loads of room now the metering unit has gone. loving the mods!

 

looks nice under the bonnet matey, keep the picture comming

 

How much does it cost for parts to convert to EFI roughly?

 

cost me about £400 inc chip and injectors

 

that good going, have you noticed any difference on the road?

 

it boosts alot smoother doesent feel as raw but its over fueling ( black smoke on boost ) so setup is next
but the starting issues i have always had are all gone fires up first attempt that was the main reason for me doing it

 

Am interested in this conversion myself.Could you do a full list of every part needed and what car they were off.FIESTA RS OR XR3i,If you don,t mind.CHEERS

 

Me too, could you list the parts needed, plenty of EFI inlet's on ebay but unsure of rest of parts needed, wiring etc.

 

Can i have a list as well please mate

your car looks mint as well fella

 

sorry for asking but if you do not have any issues what are the advantages of going to EFI and do they justify the effort

 

sierra cvh 1800 bottom pully machine work needed
sierra 1800 chv cam cover with cps cover need to be cut down
mfi to efi adapter plate or efi head
fiesta turbo inlet manifold c/w injector wiring fuel rail etc
xr3i efi 1990 loom cps wire needs extending and the fan plug will need to be extended and the origional plug used
fiesta turbo charge carrier and 90 spec rockercover
ofac fiesta turbo ecu and map sensor for ease of fitment
accelerator pedal off a carbed mk4 escort and cable from a zetec escort
sierra 1800 cvh alternator mounting bracket and adjusting arm also u will need the alternator pully

thats just roughley off the top of my head

 

Is it easy to wire it in did you use any wires of you old mfi system?

 

its easy just use the 3i main loom the only problen i had was the interior clock and the o/s interior switch

 

been a while since my last update cos of health problems

arch repaired


should of checked the other side before it went in


got my s1 kit ready to be fitted


progress is slow but its getting there

 

Top work there fella. I recon i might be asking a few questions from the man! if i get stuck doing my efi conversion lol

 

ok decided to assemble my arb it has beed to the powder coaters and with new lower arms poly bushes and nuts/washers it looks like new

 

looking spot on there mate im in the process of collecting the efi parts for my car and getting s1 kit painted ready to fit, great minds think alike

 

Nice one ,will look great on the s1 kit
