Right, I don't normally believe in this new year resolution s**t but, I kinda need to do this zetec conversion or at least try. I know what I want to do I just don't know which options are the best. Basically I want a 1.8/2.0 zetec, I will be running it off bike carbs as I have the esc sensor so minimal wiring is involved. Which engine is best suited/easiest to fit?? Also how do I go about finding a rad and coolant pipes etc??
Brakes/chassis wise, si rear beam, xr2i drilled and grooved disks with calipers obviously, green stuff pads, probably strut braces, I already have springs I just need decent shocks to match. Then finally a half cage as I think they are awesome.

Cheers

easiest zetec conversion for great power is a 2.0 zetec silvertop as you have to do is find the mounts from an xr2i 16v, or rs1800 etc.

do you have power steering? if yes then you can convert to use the steering system off a fiesta si and all the engine mounts etc. if you don't you have to find the mounts from an early fiesta zetec like the xr2i/rs1800 to be fair you'll probably feel more power from the non powersteering one as theres less drain on the engine.

but one thing about the silvertop zetec engines, most of the big boys are using them for high powered zetec turbo'd engines. easiest engine to find that's dirt cheap are the 1.8 115ps engines, then just upgrade the cams to 2.0 ones and you're halfway there to a 2.0 lol! give it a decent four branch exhaust manifold and as you want to go for the bike carbs the power will be plenty enough for your fiesta mate. you can try to find the 130ps 1.8 engines from xr3i mk5 escorts, or the rs1800 fiestas and they could be good!

if you are converting your fiesta if its still the very small engine then a full wiring loom swap over will be needed easily found on scrap fiesta si's etc also you can upgrade to electric windows, central locking etc if you wanted too as well!

as for brakes, I would go for bigger is better, so you can choose from cosworth 278mm brakes to fit under 15's, or if you want 16's you can choose 300mm ones with mondy mk3 calipers and st170 discs. or I know escort rs2000 260mm brakes can fit directly as well. green stuff pads are ok but they are only just as good as normal ones i'd say I had the same setup on my escort but in 300mm deep grooved discs and green stuff pads and they squealed like pig when braking! so switched them to ferodo pads and standard discs and they felt better!

as for the rear brakes/rear beam just make them brand new, as the main braking is mostly on the front. but still change them to new parts and fresh fluid and braking should be top notch all round! you can probably upgrade to a rear anti roll bar if you haven't got it.

rad wise well whilst you got the engine out better to change the cooling with a new radiator and hoses well you can buy new kits from roose etc if you like but again look to scrap fiesta 16v ones as the hoses are very different to the small engines

Why would he need to change the loom? He's going to be running it on carbs and his car is already running a carb engine so a zetec loom is going to be little use? Also swapping over both interior and engine loom? Really? A heck of a lot of effort for sod all tbh not needed not would I be ripping the cash etc out for electric windows lol

[Gus!!]

I already have electric windows so no problems there, and that's what I was thinking, don't I just need my crank sensor etc for engine loom??

[Gus!!]

I also don't have power steering so that's another plus I guess!! If I have the 2.0 I need a sump and waterpump off the 1.6 but if I have a 1.8 I just keep standard iirc?? Also if I still run carbs do I need the tank with swirl pot etc??

[Tweek]

All mondeo engines run the same configuration so as long as you use a 1.8 from a Fiesta or Escort then that is correct.

[Gus!!]

Cheers Wayne, so best bet is a 16v 2i or rs1800?? Also what sort of power should it be running with the bike carbs as I've never really seen figures or anything.

[SLEEMAN]

isn't the 16v xr2i engine only 105ps? surely you want something a little better

[russ-RST]

I think general range is about 150bhp with a 2ltr zetec on carbs obviously more depending on what you do ,do to it

[Tweek]

2ltr has much more torque than the 1.8 variants too

[Gus!!]

140-150bhp would be what I'm aiming at tbh!! I mean the 1.1 had 50 when it was New!!

[SLEEMAN]

theres quite a few 2.0's on ebay at the mo but they are pretty much going for the same price as a 2.0 blacktop too. but depends on your budget as everyone knows that 2.0 silvertops are good for zetec turbos as well so prices on them engines are going higher.

i wrote a few guides that you may find useful

oh and this as a comparrison of inlets injectors etc http://fiestaguides.co.uk/phpBB2/viewtopic.php?t=6290

mine was 145bhp on the rr before it came off the road

Those guides seem like they will be spot on mate, obviously the zetec one I will have to differ a bit when I get to inlets etc as I'm not running efi!!
I'd be quite worried about the timing when I put it all back together but I'll work it out!!

[mikeymikeyp]

how where you thinking about running the carbs

[Gus!!]

Off the esc pack that's already on my car mate, I have been told it works??

[hb69]

Yeah as a basic set up its ok

[mikeymikeyp]

iv heard that it works like that as well

[Gus!!]

If it's s**t I'll have to look into something else!! Lol

[Gus!!]

If I did end up putting a 1.8 out of an xr2i in, do I just need cams and ecu off an rs1800 to make 130bhp??

[hb69]

And inlet, they don't normally make 130 though, a 2.0 should do easily though and more scope for modification in the future
