Okay, so I am going to attempt to swap out my 998cc engine in the coming weeks, for a 1275cc I bought from a member on here.

I haven't seen the engine running, but the chap assured me it was a good'n... though I am aware of the risks involved with going on someones promise.

That being said, I've already gone ahead and bought various bits that I am aware of, in order to successfully carry out the swap and get me running. But I wanted to know if there is anything else that I might be missing?

This is what I've bought:

- Silicone Hoses (for 1275)
- Top Rad Mounting Bracket
- New Oil Filter
- New Fan Belt
- Silicone Rocker Gasket
- Thermostat & Housing
- Heater Valve
- Hif44 Carb
- Coil (non-ballasted)
- Stage 1 Kit (not essential but got one anyway)
- Various other gaskets

I have an alternator, 2 core radiator, water pump and other bits that I had planned taking off my 998cc and re-using.

I had been told that I might need a new distributor? I was planning to use the one from my 998cc. If I can't and need to get a new one, which distributor would I need?

Any help on this would be great!

I'd fit a new oil pump and water pump

[jamiepaulsmith]

Thanks. I'll look into the oil pump then. The water pump from my old engine is a relatively new one, only 3 or 4 months old.

[Fast Ivan]

personally I would check the crank end float, remove the head to check the bores and service the head

fit a new clutch

renew the engine mounts

and I think you'll need a longer top engine steady bar

[Rocket.]

have you thought about trying to start the engine outside of the car ?

 

Might be an easier way to save a lot of hassle if there is something wrong

[psychobob]

is the 1275 block from a carb'ed model? I only ask as the block I used was originally an spi, which brought up  a few other issues. like fitting a temperature sender?

[jamiepaulsmith]

Yes, I do believe it's a carb'ed model... I think? Is there a way to check?

Yes, I do plan on fitting the ancillaries and trying to start the engine outside the car first. I'm very new to all of this, but is it really 'necessary' to fit new mounts and service the head etc. just to get me up and running? That could always be done at a later date, surely?

I'll get a longer steady bar though.

[nicklouse]

in your images one is an A series and the other is an A+

 

dizzys have different fittings. and there are other mounts that are different such as the alternator bracket.

 

so what exactly have you got and what exactly have you bought?

[jamiepaulsmith]

I've listed everything that I've bought in the first post and I have a Aluminium 2 core rad, alternator, water pump and distributor, all currently fitted on my 998cc. The dizzy on the red engine is the 1275.

[nicklouse]

so you are going from 998 A series to 1275 A+

 

was this bought complete? what clutch system is fitted? what was the old one you might need a new clutch hose.

 

why by new stat housing? the one of the old engine will be fine.

 

you could well need to re do your wiring for the starter  but again without knowing EXACTLY what you have bought who knows.

 

you may also need to change the engine mounting system if it did not come out of a Mini.

Hi Nick, if I'm honest, I'm completely unsure on how to tell the difference between an A Series and A+. My 998cc is the original that came with my car (1984 Mini25) and the 1275cc I bought from a guy on here. I think it's early 90s.

 

The 1275 was bought complete with gearbox, clutch and housing, oil filter and feed pipe and a water pump, but that's really about it.

 

I've bought a new thermostat housing, as the one on my 998cc was looking shabby.

 

No idea with regards to the starter and wiring. I've attached images of my current engine bay with 998 in situ.

 

I know the 1275 came from a mini - Clubman I think - so not sure if that makes a difference regarding the mounting system?

 

With regards to exactly what I've bought and what I have, I'll list these out.

 

What I've Bought:

 

• Lucas Sport DLB110 Non-ballasted coil (I also have the DLB105 Ballasted type)


• MSF166 Oil Filter (minispares)


• Top rad mounting bracket (to suit 1275)


• New thermostat housing and 75° thermostat


• ADU9102 Heater Valve (Huddersfield Spares)


• SU HIF44 Carburettor (serviced and cleaned)


• Fletcher Silicone rad and heater hoses (to suit 1275)


• Fan Belt (minispares)


• Stage 1 Kit (http://www.minispare...|Back to search)


• Various gasket inc. silicone rocker gasket (minispares)

 

What I already have (from 998cc):

 

• 70amp Alternator (bought last summer)


• 45D Distributor, with new ignition kit fitted


• Super Water Pump c/w by-pass (minispares)


• Radiator fan


• Solenoid, washer bottle, fuse box, wiring etc.

I've attached images of my 998 engine bay for reference, in-case I've missed anything from this list.

[CAU998]

Well as above your 998 is definitely an a series and not a plus. So won't be original to a car of that age. Looking at what you have both are pre verto so you shouldn't require clutch components. As its like for like. The dizzy in your 1275 is a 65d and is a reliable unit so seeing as your original won't fit I'd be tempted to use that if it works? Only requiring a loom to connect to the coil but you would require a coil to suit and neither of the above.

[CAU998]

Also I'd try to find a small water pump pulley and you may find you have clearance issues with the fan hitting the breather on the timing chain cover, so you may have to modify it to make it flatter like later cars.

[jamiepaulsmith]

Thanks for the response CAU998. I'm not sure I can use that 65D on the 1275, it looks a little worn and busted but perhaps I'm wrong.

 

What coil should I be looking at then? I only ever thought there was ballasted and non-ballasted types. If you can point me in the right direction, i'd really appreciate it.

[jamiepaulsmith]

Is this the type of dizzy I should be getting, if I need a new one... http://www.ebay.co.u...A0AAOSwtO5XI2-0
