Mk1 fiesta 1.7Puma

[n10beg]

My mk1 fiesta project has been a slow starter, i bought it from an advert on this site and she has now been named PAMMY. tonight i picked up some 6J pepper pots for a bargain so she looks a bit different to the pictures. My Girlfriends cousin owns a car dealership and has a tidy Ford Puma that's come in cheap with tatty bodywork. I intend on buying it and removing anything i need, id like to bolt it onto my 4 speed BC gearbox to start with but I have read that this is not as simple as dropping in a 1.8 zetec. Its an ongoing long term project so there is no rush to get it finished but if anyone has done this before and come shed some helpful information as i have read odd things such as the clocks have to be in to make it work and i will need an unlock code?

Based on the conversions into Ka's, you'd either need to build a hybrid gearbox or get custom driveshafts made. It is a good engine, but you'd prob be better off waiting for a ztec to come in and fit that

I had a 1.7 in a mk5 ZS and it was a quite an average engine I thought. I think I'd be more enclosed to go for a 1.8, I had a friend who ran this conversion in a mk1 fiesta on bike carbs and it went very well indeed.

The 1.7 isn't a zetec it's a yamaha (zetec SE) so doesn't have the ford bellhousing pattern but it does have the wierd ECU/dash immobiliser which as you say needs the matching ECU and dash to run, of course aftermarket ECU will sort that but not cheap ??

[BT]

Can this not be bypassed with megajolt and bike carbs? Not overly expensive option and helps things breathe a little better?

[n10beg]

yeah i think I'll wait for a Zetec to come up then, Like you say it can be done but its not cheap and this project is meant to be on a budget within reason! I'll update the thread I've got on readers rides once I find an engine!

[slater]

The SE Zetecs are great engines, mainly because they are really light weight. (an often overlooked factor when deciding on what engine you want) The normal Zetec is the easy option for sure but the thought of putting one in a car nowadays sends me to sleep lol

[n10beg]

I completely agree with you but this is my first engine swap and I am meant to be using it to get to my wedding next August so i don't want anything too complicated! plus i will be in massive trouble if i spend too much wedding money on ECU's and stuff to make the puma work!!

There is quite a weight discrepancy between the two however . In something like a Fiesta MkI the weight up front would make quite a difference.

Yes, isn't the 1.7 Yamaha engine Ali in comparison to the zetec?

[ChasR]

Yup, as is the 1.4 and 1.6. I *think* the old Zeta engines that got the Zetec name were vaguely based on the CVH engine. That would make some sense given that ZVH engines came about in the Ford world.

I remember Pumaspeed telling me years ago that in a Ka the 1.6 conversion wasn't too bad and looked factory to boot.

[zippyobrien]

Some miss info on this thread.

It's a great light weight engine

You will need the ecu ( tape code is the best as it can be hacked to run the racing puma map)
You don't need the matching clocks. Just the transponder from the key.

The bay loom is totally seperate and links the the car via 3 plugs. You would need to hack one of these to link the clocks up to the engine loom. Then keep the rest separated.

As for the gearbox. You could put the ib5 bell housing on to your 4speed. However the 1.6 gear box would be my suggestion. Shorter ratios tha the 1.7 box. This will mean using mk2 xr2 drive shafts though ( he Cvs are interchangeable on all bc and ib5 boxs.

1.8 focus clutch is the biggest and strongest yku can fit in the whole ( with out going multi plate )

A 1.7 with the tape Ecu, racing puma map and a Decat will make a very healthy 135-140 bhp. It's actually easier to get more power out of the smaller 1.6 As it has no Vvt, cams are cheap and they seem to rev a bit better. 1.7 is nice for a fast road engine.

I see no reason why you wouldn't get one in and running in a weekend of you have the bay loom, ecu and a wiring diagram.

[n10beg]

Thanks for the advice, I now am really split between 2 choices now! I would love the puma engine as it's already pretty powerful and it's bit different to the same il zetec as everyone else has... But the old zetecs are a lot more simple and even a stock 1.6 would still be pokey in a car as light as the mk1. With cams and exhaust I think it would still be fun to drive.

[slater]

At the end if the day it's about what you personally want. If you want a quick easy swap with a decent power hike the zetec is fine.

I tend to build cars for the engineering challenge and to have somthing unique so i care about having somthing more refined and a bit more unusual.

[zippyobrien]

Don't be different for the sake of it.

There's usually good reasons for common conversions.

But it wouldn't be hard to get a puma running in there

For curse word sake don't for a 1.6 zetec though. Tiny valves and a crappy 88 bhp power out put. The zetec se 1.6 engine is good ( Yamaha unit again). But if going normal zetec, go 1.8 or 2.0 only

Have to agree there, the ex wife has a 1.6 zetec escort and TBH my cortina 1.6GT spec pinto was quicker and nicer to drive (power delivery wise), great on a run mind you (fuel wise), having said that in a smaller car it wouldn't be as bad but if your going to fit a zetec why get the lowest powerd one that TBH a decent CVH would outperform ?

zippyobrien :
Is the puma differant to the fiesta Mk6 zetec SE cos i changed the ecu on one of those a month or so back (idiot welder spiked the ECU) and i couldn't get it to start without the matching dash? honest question not arguing just like to know

[ChasR]

What bortaf and zippyobrien said. I briefly owned a very clean 1.6 MkV Escort 16v. Frugal it was but it was by no means quick! If I am honest I reckon the Lupo 1.4 100BHP was quicker and even the Focus 1.6 I owned for years and that had the issue of longer gearing!

As said, with simple and thought out mods the 1.6 Zetec-SE engien can actually produce some good numbers. I think Jono (one of Dave Walker's workers) from PPC got 10BHP from one with basically a good panel filter, exhaust system, and a good exhaust manifold. I think most of the gains came from the manifold. To go further I think they eventually went to throttle bodies etc.

It is the same engine yes. Id use a mk5 fiesta a donor though. Much simpler loom and wiring.

The 1.6 will make a easy 120bhp with a manifold . Decat and map.
145 is do able just with cams. Head work will relieve 155 ish. After that you need bodies, but they'll do 200-220 on a modest budget and still wet sumped.

Cheers for that me son has a Mk5 1.25 he's had it 2 years and fancys more power oh well, i see this swap in my future
sorry for the hijack of the thread n10beg

I converted a few 1.25s back in the day. The maps are pretty similar, so if you pop a 1.6 in a 1.25 with the 1.6 maf and Injectors it will run well enough on the 1.25 ecu.

Used to do drive in drive out 1.7 conversions on the zetec s 1.6 aswell. Got them down to 4.5 hours start to finish.
