Fordmad!

Is there any threads on this and has anyone done it?

I see people putting 1.8s in or 2.0 mondeo engines but not a puma engine.

Im after abit more power and reliability then the cvh but something cheap and readily available so I see the puma engine the right way to go!

I would be on the look out for a full doner car! Either rotten or rear accident damaged

Can anyone help?

Exactly same as putting a 1.8/2.0 zetec engine in bud! U need your cvh mount trimmed puma engine with engine harness (engine loom), key, ecu and pats sensor pretty much it a few other little odds and sods nothing major use cvh gearbox rst or diesel best option but if u wanna use puma box i think u have to mess about with drive shafts not 100% on that bit

Fordmad!

Thought it wouldn't be too bad. Only real things I was worrying about was the driveshaft/gearbox bit and the wiring side.

Like I say id buy a running car to make things easier.

If you use your gearbox uou can use your drive shafts. If you use puma box i think the drive shafts are longer so you either use fiesta zetec s ones or there a chap on here makes/alters them to fit (i know i had to do this when fitting st170 engine and gearbox and rs focus gearbox but not sure if puma is the same assuming so as puma drive chain is wider than an escort) wiring is pretty simple the whole thing is simple probably easier getting donor but not a must as long as you got all the bits! Whole thing can be done in a day but wiring may take you a day itself as you not done it befor its not many wire 10 or under from memory

Fordmad!

Yeah id keep the 3i box in as ive got a puma linkage already to go on so that save hassle. Id get a donar so I know there are no faults with the engine etc!

I take it I wont have to change the brakes either as no much of a power increase 20bbhp at most!

Would the exhaust fit? Id probably get help with the wiring as im useless lol

Change your front breaks is a must its not just about engine size and power out put, puma engine is heavier than yours! Fit rs turbo breaks all round or rs turbo rea hubs (theyre bigger) mondeo front calipers with st170 discs or rs turbo rears and escort cossie fronts!
Cant remember about exhaust you can use yours but have to adapt it to fit puma down pipes or have one made

Sounds like a cool project. The puma engines are spot on.

Cheap as chips to i know someone with puma lump low miles Ł150

GVK.

Starter motor will be in different place if using an old XR3i box??

Is there any reason your thinking puma engine as they will not make more power than a 1.8 or 2.0 zetec on carbs bud

Zetec_mk4_XR3i

Would be an interesting conversion!

Remember the exhaust is at rear of Puma engine, and the stock manifold and down pipe is quite bulky...I'm not sure if it would fit? An aftermarket 4 branch manifold might be needed!

Get some pics up

Fordmad!

Right it looks as im going ahead with this plan. Although I have my engine running fine now im sick of it always going wrong.

Ive want to keep my 3i but really want a puma so looks the best way to do it!

Im bidding on a rotten puma so that will be the donar car

Any more advice on the conversion would be really appreciated from fitting to wiring to parts needed.

Thought you had fixed problem and had car on eBay.

Fordmad!

Yes its all fixed. Its on ebay but ends with no bids. Don't really want to sell but sick of the unreliability of the engine so going to go down this route

Zetec_mk4_XR3i

Not sure how the engine mount on drivers side is going to work mate, they are totally different mounts and Puma one sits further forward than mk4 one?

Good luck with project though and get some pics up!

Fordmad!

Im sure it'll be okay. The lad doing it builds metro 6r4s with type r supercharged engines for a living so shouldn't really struggle with this. Well I'm hoping not anyway!

Should have a rotten puma bought tomorrow so I should make money back by selling my old 3i engine and what I have left from the puma. Just need to pay for the labour!

Tbh I wouldn't do it there gutless little engines my mates escort gti can easily overtake my pum'd fiesta after 70mph and it was running std bhp....

mattxr3i

1.7 Puma engine is all alloy and is really light, lighter than the CVH in the XR3i. It's a conversion that I looked at for a mk4 Track car but decided to go mk6 Zetec. The exhaust will need some fabrication due to the intake being at the front and the exhaust at the back. They are very good engines and without a CAT, it should rev even nicer. Look at the racing Puma for upgrades too, to get to 150 odd bhp.

Surprised that a standard Escort GTi was quicker than a 1.7 Puma, the Puma we had was pretty good and I would have thought would have been quicker than the GTi. Notice it's a conversion, did you use the 1.7 ecu for the variable cam timing?

As for brakes, I would upgrade to the RS Turbo 260mm disks and pads and you should be ok.

Fordmad!

Tbh I drive my mums puma all the time and also used to have a GTI and puma is quicker revs quicker and for me is an all round better car.

I want the puma conversion as theres more about. Plus everyone goes down the 2.0 zetec route.

With a few tweaks I think id see 130ish bhp from a good engine which is a lot better then I have now, same mpg, far better reliability, parts easier to get hold of and its different from the norm

Stick a cone filter on it and a 4 branch manifold. You will notice the difference.

I fitted a cone filter to my pooma a few weeks back and it is defo quicker and the throttle response is better too.

Straight_4_N/a

Its quicker bottom end but after 70mph thay haven't got as much pulling power as the 1.8 and its only quicker bottom end because my fiesta is loads light than an escort.
yeah it has 1.7 ecu lol also has 4-2-1 manifold decat and cat bk exhaust system and feels gutless top end lol.

Puma engine should be lighter as it's all aluminium

Fordmad!

Well tbh im not mad for speed so that doesn't really bother me. Its reliability im after more then anything.

Just got off the phone and hes giving me a quote for the work tomorrow.

Straight_4_N/a

Tbh theres not as much available for the the 1.7 compared to the 1.8/2.0 and the 1.8/2.0 is a much stronger engine 1.7 bottom ends are made of butter lol.

also the cost on tuning a 1.7 is much higher than a 1.8/2.0 and the 1.7 wont make as power power as the 1.8/2.0 with the same mods and the 1.7 will have loads less torque.

Straight_4_N/a

Lol then your looking at the wrong engine! Zetec-se are throw away engines and really not known for reliability lol,

Fook it just stick a mk1 frs engine in it. Cant beat some booost.

Fordmad!

They arnt that bad and im not looking into tuning it. Reason im going for that is there are plenty of them around see rotten pumas up for peanuts all the time

Fordmad!

What power are the 1.8 mondeo engines? Are there any ones better then others?

rdvil

There must've been something wrong with a puma engine that couldn't beat a 1.8 escort. Stuck on torque limiter or somesuch, thinking it's always on 1st or 2nd gear?
Only ever drove the 1.8 zetecs in Focus & Mondeo, and those lumps don't feel near as lively as a Puma. Puma vs. 2-litre Focus, I'd bet on the Puma.
No idea about tunability though, but as std, I'd say the Puma engine's a gem, and this idea has my vote.

luke19790_3

Blacktop will be 115 just fit a 2.0

mattxr3i

2.0 Duratec is also has to be in with a shout from a MK3 Mondeo. 148bhp in a Mondeo with all the eco rubbish and are dead easy to tune.

Fordmad!

Ive owned a mk1 2.0 focus ghia and it would of beat a puma when you hit 70-80ish but id say puma would be quicker then a GTI all day long.

If I could find a cheap mondeo id go down that route but the seem thin on the ground now

CrOwSoN15

Not so sure about that, a 1700 SE comes in at around 80kg..

mattxr3i

Duratec has a different bolt pattern for bellhousing so could be a pain thinking about it.

Just buy a mint puma and just mod the puma.

Straight_4_N/a

The limiter in on in 1st and 2nd gear and if you have a post 2000 ecu its much more aggressive than the pre 2000 ecus and post 2000 ecus have more of an eco map than pre so even less guts.
the problem with them there limited in 1st and 2nd and time your in 4th it starts to lose its get up and go so you really only have 3rd gear for full power, where a gti still has power in 4th so shes quicker.
In a straight line there next to no difference between the 1.8 and 2.0 focus lol and a puma would be dead in the water just after 80mph.

Straight_4_N/a

And the rest lol the 1.6 comes in at 81kgs bare and the 1.7s heavier lol.

Straight_4_N/a

Ive owned a focus 1.8 2.0 and currently have a 1.7 fiesta and I use my missus 1.6 focus and the 1.8 with stick with a 2.0 till there both out of puff the 1.7 runs out of puff just after 80mph (ish) which is miles before a 1.8 does lol.

and tbh my missus 1.6 focus feels like it has more pulling power bottom end but thats because the 1.7 is limited.

Fordmad!

So am I being stupid or could you just swap the ecu's for a pre 2000 one?

Glenn_

iTrader: (1)

Pre 2000 uses the 2 lambdas. You will also need the key from the car the ecu came from.
