well iv got my zetec s fiesta as a project. looking into engine conversions as i miss my rs turbo a great deal. the wiring bit is the only thing that blows my mind away tho.

i was thinking if i was to fit the fiesta rs turbo lump on a diesel courier van g-box so the mecanicals are done. the wiring side i was thinking that instead of cutting looms up to make a super loom, i could just transfer a complete fiesta rs turbo loom (or xr2i) into the car..... would this work?

cheers

 

If you want to use the FRST engine then you will need the loom and management for that engine, XR2 would not work, you may also need the fuel pump as the one you have may not be able to flow sufficent fuel for the demands of the replacement engine.

Martin

 

so in theory swapping the whole car loom would be easier.... its a on going project so ill have time to re loom the whole car... dont want to start cutting 2 looms into one

cheers mate

 

Yes and you also need the ECU as the S ECU/mapping will not run that engine. This can bring it's own problems due to immobilisation (If the FRST has such a thing?)

Martin

 

yeh cheers mate, looks like to keep things easy for my and whom ever i get to set up the car the frst complete set up will be better. or ill end up with some hybrid super shit loom that does nothing lol

cheers mate

 

easyer than that mate, you can cut back you engine bay loom (starts at the fuse box at the back right of the engine bay, runs lights ect aswell.) cut all the engine sensors out bar the gearbox sensors and fan switchs and the coolent sensor (this tells the ecu what to display on your clocks)

then its 7 wires to put your frst loom in,

standard pumps are pretty good tbh so ok to start with.

 

But are the connectors and sensors not different on the CVH? Will the ECU connector fit the other ECU, I know there both EEC but the pinout may be different, thats if the connectors are even the same?

Martin

 

you have to retain the stadrd zetec s ecu, it runs the lights and dash , heater ect, all runs through it and its fuse box,

you can how ever trim the loom back loosing most of the engine baysensors,

then lay the frst loom over the top, just popping the ecu inthe glove box then connect up the appropriate 7 wires

so 2 ecus

 

What are the 7 wires for?

 

Rev counter
perminant live
Switch live
Oil pressure switch
Earth
Starter solenoid coolant

 

Cheers bud. I jus remembered about the rs turbo rear set up you wanted...when i went up to that lock up it had be broken into so i forgot as po po had to sort things out before i had access again. Still need it?

 

Well takin a slightly sufferer route now. Putting a 20 valve turbo in it hopefully along with tt gearbox lol.

 

Haha kewl... I got the misses a 10plate zs focus so fiesta is getting the turbo attack lol

 

Lol. Do it. Didn't u have a focus st aswell ?

 

Yeh. Sold it so misses could have a new car. Lil boy is 5 month old so 3 door was a nightmare

 

Yh can imagine.

I personally wouldn't put a cvh in a zs. Do a zetec turbo or get ss4s and throttle bodies.

 

To add you will also need to connect CPS, TPS, ACT, cam sensor (AKA phase) and knock sensor etc via the FRST loom there will also be a connection for the Amal (Unless using manual boost control)

Martin

 

i was going to use cvh just because i have the block ready to use for mocking up... i do like the idea of a zetec turbo but i like cvh as its something i have worked on time and time again....hmmm not sure:S would it still run fiesta turbo management? or would it be worth putting standalone on?

 

I would say standalone, the EEC may be able to run it after being mapped though, many go down the Omex route for ZT.

Martin

 

if you go megasquirt its easy, as you can still use the rs turbo bay loom, and all its standard sensors inlet ect.,

would make for a nice fun car, and can use standard rs turbo rad and intercooler and exhaust, so makes for quite a simple swap;.

use a sport ka gearbox, better ratios.

i can supply you with a modified lsd for that to

 

I know zetec turbo should be the way but im still thinking cvh as its cheaper

 

Or as i just read in fast ford... Decomp plate on standard zs lump and turbo that lol

 

Doeesn't that cock up the cam timing though?

 

have a look in fast ford... the oc with turbo'd lump

 

Floating pulleys so cam timing will be spot on, I've got a turbo manifold for both zetec and zetec s engines

 

is there anything you dont have that ill need for this conversion :P lol

 

Lol. An ecu. But u can run mega or micro squirt. I was thinking about doin this conversion before. Like home engineering.

 

so what did you work out you would need? you can do some away from home engineering at my house if ya want lool

 

Rods and pistons ideally but decomposition and rod bolts would do. Oil cooler kit, drill sump (use a puma one as holds extra litre) puma inlet (metal) megasquirt and some bigger injectors (2.3 duratec ones) and a 1.6 focus zorts manifold to make into turbo manifold (there stainless) and a t2 or t25

So a bit of outlay but could all be done on budget apart from managment.

 

Since you said zetec tturbo its really making me think....200bhp and potential for plenty more.. Ill be happy with 200 just for a toy. That way the zs box. Ka bellhousing and modified diff will be fine. No need to change gear box. Or for 200 will a cvh be good?

 

I know you said ka gbox but the zs ratio will be fine till i get bored or blow it up lol

 

If u go cvh or zetec u will need a ka box for the bell housing. I blew 3 gear boxs on my zs lol the standard diff is weak hence wanting the LSD. Cvh will do 200 yes just questionable reliability were as a fresh built zetec will cost a grand but only need about 10 psi to do 200..

 

Will the diff you said you have do the job? Is that a complete build... Turbo and everything?? really thinkin zetec turbo for that price zs box will survive a short life then lol

 

U need the ka box for the zetec and with the diff fitted its good for 200 and a hard life. Zs box won't fit.
But if u got a cvh and management is go with that. Have it done in a weekend.

 

Cheers... You do know your stuff..... Im now not sure what way to go main thing i want is turbo power but budget as i dont have mega money spare it

 

Then go cvh. If u want zetec budget at least a grand for engine then a grand for ecu ect. Plus as said if u go cvh u can use rs tad and ancillary s

 

Cheers. Will be quizzing you more soon lol...if i got the loom could i pay you to make it?

 

I'm sure we can sort something mate. U got a fiesta turbo loom?

 

Na gtta get one.... All i have atm is the zetec s lol what bits you got that will help me?

 

xr2i and fiesta turbo looms ARE the same, the only difference is the map sensor and ecu.
