spitfire 1500 ford puma engine transplant

Recommended Posts

Hi all,

I'm new to this forum and quite new to mechanics too, but just bought a spitfire 1500 with a couple of friends (some of which know a lot about mechanics).

We're thinking about transplanting engine and wondered if anyone has experience of the Ford Puma 1.7 engine in spitfires?  It's small and light and not over powered (at 120bhp).  It's called Ford Sigma or Zetec SE.

Any advice on how easy the transplant might be or whether it would be suitable much appreciated!

Many Thanks

Welcome.
My sort of thinking!

However, I don't think there is a simple bolt-on gearbox to convert to RWD. Have a look at http://www.locostbuilders.co.uk/index.php as people on there have done just about every engine in something. I know the puma engine has been uswed but how easy is a different matter. There is also the small matter of ecu's. It may be possible to use the std injection, or you may need something a bit different, megasquirt, or megajolt with either bike carbs or webers etc. Not sure, outside my limited knowledge.
However, I can personally vouch for the Zetec E (mine was, next one will be 1800) as a well balanced setup. About 150bhp on carbs, more on injection. Same weight as the Triumph lump.
I have recently seen a pinto in a spitfire too, and that needed no bodywork except a GT6 bonnet to get it in. And a chopped manifold, but any engine swap will need that unless you are mega-lucky.

BUT if you have limited mechanical knowledge, you may wish to learn some skills (welding for one is rather handy as you will need to make up engine mounts, brackets and cut/weld bits of bodywork etc)

Zetec SE is a good engine.  It is a Mazda design and has different bellhousing pattern from the normal Ford one.  I have read that it matches some of the MX5 gearboxes (later ones?) but I'd check that before parting with money!  Could try the Retro rides or PPC forums to get that question answered.

Erm,   I thought the 1.7 Puma engine was a sort of one off special which Yamaha (motorbikes, not pianos)  helped develop?????  Could well have been based around a standard Ford / Mazda block though.  Further investigation needed.............

Mind you, didn't Yamaha have a hand in the 1.25 engines too?

I think they did 1.4 and 1.6 Pumas too, more like your boggo Ford enignes.

I believe that is correct, according to wiki at least. Developed with Yamaha, and then used by ford and mazda. The whole lot is so incestious these days :-/

Anyway, there is a bellhousing available

There was a herlad with it in at Leatherhead this year, and he was running Twin SU's!!!! custon ali manifold too, so very "period"
I have also been in contact with a chappie doing the MX5 conversion, looks well but the gearbox is very long, and the gearstick is waaay back, much more so than the Type 9 conversions.

"Straight forward" is a matter of opinion ;)

Zetec SE is most common in 1.6 form with millions in the Focus.  One in my drive (management transport).  Suprisingly torquey and willing for a 1.6 and good on fuel too in spite of having to drag the fat Focus around.  1.7 Puma version has variable cam timing as well as a few extra ccs.  Possible to get near 200bhp from the 1600.

There is a guy on the Retro Rides forum who has put MX5 engine and box in a Herald 1200.  As he runs SUs I suspect he's the same guy Clive met.  No particular difficulties reported but very little detail given.

I like the Zetec SE idea  :)

Hi,
cheers, great discussion.  It sounds like there's probably a simpler option than the puma 1.7 (although I bet it would be a great one).  I don't really want to get into a transplant that's not been tried and tested.  I think the focus 1.6 is not quite the same engine, it doesn't have variable valve timing, I think it's a zetec-e but it does sounds like it's the best option. Is the Zetec-E engine the same in fiesta, focus and mondeo? I read that the mondeo one is heavier and not so suitable?

Do you know where i'd get all the bits to make it rear wheel drive and what gearbox would fit etc?

Cheers,

http://www.zetec-cat.co.uk/  gives the basics of how it all bolts together
http://www.locostbuilders.co.uk/index.php  lots of kitcar stuff, good for a browse but variable knowledge (ie some are clueless, some are genius)

My spit had the 1800 (from an escort, but basically the same as all mondeo/focus etc zetec e engine) weight same as std spit lump. Fits up to type 9 gearbox. Simples ;)
