Get a 7 port and injection and maybe forced induction. Its a false economy stuffing about with the asthmatic 5 port and its Siamese ports especially when you can set up injection for trouble free running and more power than stuffing around with a carb.

If you are doing any machining then get a 1275. Machining costs are the same but you end up with a much better engine.

An a+ 1275 from japan would cost next to nothing right now as minis in japan have reached the point where they are too expensive to be kept on the road.

How much are you willing to do yourself or what specific skills do you have?

Would a tuned 998 be a waste of time?

Ahem, go ahead and recommend injection and 7 port heads but don't knock 5 port heads

I love small bores and wouldn't hesitate to build another with even more power.

They certainly don't run anything like a stock 1275...

Compared to a stockish-mild 1275 a hi-po small block is 100 times more fun, revs happy - more than a mildly worked 1275 and fast enough to get you into trouble.

The fun is in the sound, keeping it on the boil and using every last inch of power it can muster.

My 1152cc with 12G295, 40mm Dellorto, RE13 was quicker than a lot of 1275's and parts are cheap.

Where's the fun in a stock 1275 when you can have a precision tuned smaller engine pumping out more power for cheaper?

I'd go for a stock 998, ported 202, and a turbo.

After the initial expense of getting all the bits for the turbo is done you should be set.
If you run low boost no need for an intercooler.
If you blow up the engine or smash the gearbox you can unbolt all the Turbo bits and bolt them onto another 998 and off you go again.
Happy Days

With 1275 prices on the rise still, its doing many things:

A) making them harder to find and buy
B) making small bores cheaper to buy
C) making blokes like yourself choff around bagging on the smallbores

My 1152 will whip most mild 1275's (yes but for the same amount of work a 1275 will be amazing blah blah blah) if my engine were ever to blow up I'll just pick another small block from the pile and away I go...

As PDJ said, turbo it, let it blast any NA engine, if it breaks chuck it on the next 998 block...

“A turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.” - Jeremy Clarkson

Im not sure what the eye rolls are for? Is there some advantage to a 5 port Im not aware of?

Apart from being cheap, but then they are only cheap if you can do the work on them yourself.

The 5 port does a good job and was designed by a man with good credentials, Harry Weslake (Jaguar, f1 engines) if your keen to have a go a 202 head can be ported to flow enough air for 60 bhp and have good road characteristics. Stick a webber it and a decent exhaust and it will sound horn, go hard and idle sweetly. A turbo will drown out the exhaust note.

Or if money is no object and you absolutely have to have twin webbers on a 1 litre engine.

Fitting a 1275 isn't as straight forward as buy, build and drive. Additionally the 1275's have pretty average harmonics, I think I remember someone on here complaining they used to rip the mains out of the block if you pushed them too hard. However if its power you're chasing you cant argue with displacement.

You will need to upgrade the brakes (even if it is stock) where as a modified 998 will avoid this. Don't try to avoid it, insurance will get you eventually.

1275 or 998? your choice, I've made mine.

I would definitely still budget in front discs on a modded small bore........
On my first drive out with my fresh engine...on drums...needed some fresh underpants.
I went home and covered it up until I put discs on it.

Its ridiculously cheap for the benefit you get. Landed from minispares uk was just a couple of hundred. (Provided you can fit it yourself)

yes, front discs will be a must.

My first clubman had suspect drums and i ended up having to go around a corner at a t junction on the footpath one day. i was heading down a steep hill and after the brakes didt work too well a combination of pumping, engine braking and handbrake slowed me to 30 odd but enough to make me very worried.

So, the front disc set up will be second hand too... recommend getting metro discs from the UK? Or utilise a set from u-pull-it off a small car?

Ideas?

Most s/h Metro sets I've seen from UK are covered in rust and by the time you rebuild them properly, you could buy new.
And, if you are thinking of running 10" wheels, 8.4" discs are too big.
