Correct ancillaries for 1275 Marina

Postby Andy W » Sat Oct 15, 2016 6:35 pm

Hi,
My Traveller has a 1275cc Marina engine. I read on a thread here that the 1098 ancillaries are restrictive for the 1275.
I think my Traveller has the 1098 ancillaries but do not have the knowledge to know.
Could you folks look at the photos & let me know please? If I could do with upgrading that is fine...
Thanks in advance!
Andy W.

Yep you've got the Minor combined inlet/exhaust manifold, carb and exhaust - wont be doing much for the performance :(
Your best bet is to get a Mini alloy inlet manifold with an HIF44 SU to go with it, and a Midget 1275 exhaust manifold feeding into a decent 1 1/2" system - but there is a bit of faffing needed to mate the down pipe to the Midget manifold. There are tubular exhaust manifolds available with a downpipe that fits straight on as well.
The easy option is to get a Marina manifold, most of the big suppliers make an exhaust system that fit's straight on, but you will still need to find a HIF44 carb as well.

Thanks for the reply.
I'd like to squeeze what performance I can from my engine as I do a lot of miles in the Traveller.

There is a Marina manifold on eBay but it states that it's for an SU HS4 carb -

http://www.ebay.co.uk/itm/331995552405? ... EBIDX%3AIT

Is there more than one variant of Marina 1.3 manifold perhaps? :?
Scooting around on eBay, HIF 44 carbs seem easy enough to get.

The exhaust part I can sort out in time, I can TIG a little & have made a couple of motorcycle exhaust systems.
I hope you don't mind the novice questions! :oops:

HS4 is an 1 1/2" carb, it will do the job but HIF44 or HS6 1 3/4" would be better.
This is the type manifold you should be looking for for best performance

http://www.ebay.co.uk/itm/CLASSIC-MINI- ... SwFqJWlmJc
and maybe something like this

Shop around for the best prices though as you will need the rest of the system too.

I've just fitted a Midget exhaust manifold and Mini inlet to my 1098 traveller and it works very well but I've used a HS4 because of the smaller engine, the same set up on your 1275 with the bigger carb would be a big improvement on what you have.

viewtopic.php?f=47&t=11516&p=133383#p133383

Like said there's a bit of faffing and fettling involved getting the downpipe to fit onto the manifold but it would probably work out cheaper than the tubular system, depends on if your handy with a welder and pipes. There are usually second hand manifolds available on ebay so it can be done on a low budget, my inlet cost me a fiver and the exhaust manifold under £20 but I waited for the right ones to come up.

This one looks like a contender, a slightly different shaped inlet manifold...

http://www.ebay.co.uk/itm/Inlet-And-Hif ... SwpLNX-ovD

Some inlet manifolds state "water heated/cooled"- are they different?

Oh dear, this is all getting me hooked on a new project..! :)

That's the exact same manifold I fitted :) You can get them pretty cheap but it's the carbs that are becoming expensive, this one would be perfect for you as it will already be set up for a 1275 and it has the abutment plate between the carb and manifold to clip the choke and accelerator cable too (you can pay around £20 just for this if you buy everything separately). The water heated ones (like the one in the listing) have the heater return piped through them to prevent the possibility of icing up of the carb in the winter, most people dont bother as a cooler fuel air mixture gives a bit more power.

I got it..! :D
£85, a reasonable price I think.
That's the inlet & carb sorted...gotta keep my eyes open for a 1275 Midget exhaust manifold now.

Thanks for the help & advice Panky, its appreciated.

Pretty good :)
You will need a filter too, a K&N is the best but I found it a bit noisy for every day use. A Mini one will fit fine

This type

http://www.ebay.co.uk/itm/classic-mini- ... Sw65FXsJxd

I bored some extra holes around the outside of the air box for a bit more flow, 60's style tuning :D


and you will need these to fit it to the carb

Oh good grief! :shock:
Now I remember why I mostly hang out on the MMOC site...it's easier to make myself avoid anything modifications wise! :roll:
This site is like mod-candy!

I went & bought a second classic car last night as well - now I've got an empty wallet & an empty bank account! :shock:

Ah! The JC Midge is also a Moss car (JC = John Cowperthwaite, Moss was his company)

The Midge folk split from the Moss Owners Club, you can find them here:

The hillclimb Midge on eBay in Bath looks scrumptious & not too far from you........
