hey , ive got a mk3 fiesta witch origenaly was a 1.3 now its running a 1.6 mfi engine on carburetor witch is an easy conversion , now i want to run injection without any major changes ie full engine change and i'd like to keep it running on distributor , i know i need an mfi-efi adaptor plate to run xr2i or frst inlet manifold but is it posible to just edit out the coil pack wires on the loom?and just have it running mostly the fuel management , idealy this is to get the car ready for when money suits a 1.6 turbo conversion ,
are the xr2i and frst looms the same ? i know the 2i doesn't have boost control? but what else is different ? some rs turbo's run distributor thats why i'd like to keep mine so the change over is "simple" ,do the ecu's cross over? if the same type ofac or ofab if thats right ?

bear with me im a novice at this and probrably cant spell any help to get me to my goals will be much apreciated , sorry if repeat post

does any body know? surely theres enough technical boffins on here to go yes or no , some one ask someone who might know cheers

hi buddy have splice'd efi looms into mk3 before quite easy these a ecu pement live on red and a ignition live black these can be found on the efi engine loom to interior loom connector 8 wire connector on the engine bulkhead there is a green wire for revo will have to doublle check what the other wires are for, why would you want to run a dizzy seems pointless going half the way as the ecu alters the fueling and sparc in sync and would imagine would get confused also for the work thats involved ie changing flywheel for one with cps teeth for crank sensor you might aswell put the coil pack on

shepherd-racing

yeah i think im going coil pack to be honest , ive got an old escort fly wheel the small clutch pattern on , im told its lighter , so realy its looking like more hassle then its worth at the mo

fezzielove

yeh i would go all the way buddy dont know about the small flywheel thought they were all the same if you struggle to find a efi i know some one who has 5 or so in blackpoool

To be honest, and please dont take offence, it sounds like you need to know more about what your talking about. Prehaps you are struggling to put it into words? From what i understand you have a 1600 cvh, with a distributor and carb? and you want to make it k-jet injection? and a future turbo conversion requires this?

shepherd-racing

yeah pretty much , but i think its going to be easyer now to just put turbo engine and loom in at once , didn't want to waste the engine ive got as its over bore'd lightened ballenced internals etc cheers for your help

chaffe

yeah best to use all the frst bits, the twin coils are bulletproof, better than any distributor set up. you will need a CPS and the edis4 module and loom for the ecu to run anyway, regardless of wether you use the coils or not.

yeah my english is poor , i dont know what i need thats why im asking so now we know were i need to go what bits do i need to change over? fuel pump ?( 1.3 injection pump is there) should i just buy an inline pump and use in-tank as extra?

are all frst running the same loom - ecu etc? so if i can only sauce parts from breaker etc i can mix and match? donor cars an obvious choice but buying one defeats the object of building one

what parts do i need? ive got a deisel box already , presume i need loom - ecu - clocks? - mafs but what else? they dont use lambda sensor do they?

mrjenrst

tbh mate you'd best read up on them first otherwise it may cost you a bit of coin. Why have you got a diesel box?

shepherd-racing

im told theyr stronger im doing my reading up and asking questions

chaffe

whats stronger? stilton or kippers

shepherd-racing

the deisel box is , isn't that why alot of zvh'ers use it? taller ratio top end, good differential ,

just want to know what bits i need for conversion now please

chaffe

Negetive, diesel boxes are internally the same and therefore are NOT stronger. They do have taller ratios though. An MTX75 (as in mondeo, mk5/6 RS2000, or mk5 TD/XR3i 130) gearbox is, however much stronger. But fitting this box requires many custom parts and a bit of engineering

shepherd-racing

cool , not realy fussed just want turbo now

chaffe

Thats the spirit

shepherd-racing

so then chaffe what do i need? other then the obvious? loom-engine- intercooler?
what else ? radiator?

mrjenrst

An frst donor car otherwise you'll just be going round the house's to get what that can offer for a lot less.

chaffe

yeah, a rotten frst would be astart

shepherd-racing

decided to go a different route , thinking of just getting a cam and bike carbs and look for another car thanks for the help everyone

chaffe

Oh, not soo good best of luck all the same
