Chap at work had the following lying around in his garage and offered me it free of charge, of course i said yes, plan is to rebuild it for fun and possibly use it in my kit car or sell. From what he remembers his son took it out of a Fiesta and it's a 1.6? From what i can see its definitely 16v and has a zetec rocker cover but an EFI inlet manifold, So I'm thinking single point injection 1.6 Zetec? From an XR2i? My ford knowledge isnt amazing however. Everything is there including new cambelt/tensioners, new gasket kit and new head bolts which is great, all I'm missing is a bottom end essentially. I suppose my question is what bottom ends work? Will any 1.6 Zetec bottom end work? Will a 1.8 bottom end work? Here's the pics if anyone could give me any more info it'd be much appreciated imgur.com/a/c4LbL81Also anyone know how useable it is with a type 9 in a RWD config? I have a half built kit car with a mk2 Escort rear end so this could be ideal really. I know the 1.8 blacktop works but know very little about the other engines

This might help a little, assuming we are talking a Zetec-E from a Mk3 fiesta, then it will be multi point injection. The XR2i was fitted with a 1.8 and the 16v Si got the 1.6. The Mk3 RS1800 version is decent however, giving 130bhp from the 1.8 as opposed to the 115 regular 1.8 16v. The 1.6 isnt much use I'm afraid, its not a very popular choice due to the power being no better than it's CVH 8v predecessor. www.projectbobcat.com/guides/ford-zetec-enginenot a Zetec-SE from a Mk4 onwards is different to the above

Yes that’s a ‘true’ Zetec, generally referred to as silvertop. 1.6 are obviously fairly undesirable compared to a 1.8 or 2l.
It will bolt up to a type 9 but you need to mix and match the clutch setup a bit and you need a specific starter. You’ll also need a custom sump to make it work in rwd configuration.
They go well compared to a pinto or whatever though. I did one in a minor that already had a stage 2 pinto setup in it, it got a 1800 on bike carbs. Made a dyno proven 145bhp and the fuel economy went up too.

Thanks for the input lads! In terms of bottom end what am i looking for?
What bottom ends are compatible with what i currently have so i get the engine built up.

Just get another engine. Ten a penny. Can't remember if there is any differences that would stop you bolting the 1600 head to a 1800 or 2000 block but it's a bit academic really. Better off just buying a whole one.

Humor me, id like to use this engine even if i don't end up using it in my kit car i'll have fun building it and its cost me nothing bar sourcing a block.
What blocks could i use? 1.6 zetec only? 1.8? 2.0? what are the implications of the larger capacity blocks if they line up

Also assuming the block fits and works fine would a blacktop 1.8 block not make it a damn sight easier to mount it RWD in a kit car? I cant imagine using a silver top 1.6 head will alter that

Hi Dan,
I'm not sure if you can mate it to a 1.8 block, it's got very restrictive valves (26mm as opposed to 32mm on the 1.8 and 2 litre engines). I know using the larger heads on the 1.6 engine is a no go, so presume the other way round would be an issue as well. You could perhaps try the locost builder forum?
A blacktop bottom would certainly be a bit easier to find nowadays but I'm sure there are issues with getting the cambelt tensioners to work with a silvertop hybrid which would require additional work.

To be honest the 1.6 head would be best served keeping a door open in isolation. No point trying to locate a 1.8/2.0 bottom end for it.

Dan has asked that we humour him and plough on regardless in this circumstance Phil. Polished up it might make an interesting bit of art though

It would certainly make a “nice to look at” piece all polished up with a piece of plate glass on but I still wouldn’t use it as a motive power source 😂

Alright chaps relax the humor me was more the fact that despite asking on multiple forums people telling me don't without any sort of proper educated reasoning why is pointless unfortunately forums can be filled with people repeating what they've heard without knowing why. This place usually has some well informed people on the older stuff! Thank you bobcat for explaining why I appreciate it!
Should always ask why in my opinion, now if somebody asks me the same question one day I know why it's a wasted exercise instead of just saying it is because some bloke said it
But if the valves are as restrictive as you say that makes sense why it's a wasted exercise! I'm more than aware I can get a different engine no trouble but it seemed a shame to waste a skimmed 1.6 head with fresh parts for it!
I expect I'll source a 1.8 for the kit car and one day build the 1.6 as a seperate engine for my own entertainment not to be used in anything.

Sorry if I sounded harsh but Bobcat had already hit the nail on the head. The valves are very small and probably about right for the 90bhp that the 1.6 Zetec made. I know where you’re coming from - seems a shame to dismiss a totally functional piece of equipment even if it’s not actually that good or useful (compared to the plentiful alternatives out there). That’s probably why I’ve got piles of stuff still hiding everywhere. I’ve no use for a Zafira fuel tank but I’ve got one taking up space “just in case” and because someone said they’d chuck it if it wasn’t collected. It’s got a new pump and filter on it too

No not at all mate I get where he's coming from just always good to question! Also will a block from a later 1.6 focus silvertip zetec work? For the sake of building it up anyway

For the sake of building it up anyway from my hazy memory of early Foci, the 1.6 in them is a Sigma engine, or Zetec SE and not a true Zetec engine. also has pretty much nothing in common with the bigger block either, being all alloy whereas the big Zetec stuff is iron block

Might well be given the Focus came out about the same time as they went blacktops in the Mondeo - which is about the time the Signa/Zetec SE came out?

The Mk1 Focus got the blacktop zetec in 1.8 and 2 litre variations, I'm not certain on the 1.6 though.
Speaking of the Zetec SE engines though, they are great little engines, developed in conjunction with yamaha.
