Can you do it? don't the 998 blocks have offset bores?

hi im not a 100% sure to be honest if it cant be done ould you be able to tell me how much of a difference performance pistons would make with the correct crank?

[lrostoke]

Pretty sure 1275 isn't possible from a 998

80 thou over is available and I'm sure I've seen slightly bigger, 80 thou bigger pistons are about £42 each thats about 1061cc I think ???, then boring and honing probably £100 or so.

Plus seals, gaskets, new bearing shells, oil pump.

It would be much better to buy a 1275 engine if that's what you want. Small bore A's can be tuned in to nice little screamers but nowhere near a 1275, £ for £.

As Ethel says, hover a 998 can go upto 1215cc if one is not available, also I recently heard from someone who states that he has converted a 998 using 1275 pistons... not quite sure how though as several people have looked at doing this over the years with no success, however .....

Agreed...... better to transplant a 1275 unit from a donor car. Even if you could rebore a 998, an engine transplant would be a lot less hassle than a rebore and probably cheaper too. Whats more you could sell your 998cc unit on fleabay in order to part finance the cost of the 1275cc unit!

998 or 1275? i would just transplant a 1275 into your car for a smaller cost. The 1275 engins can be picked up for about £100.00 or so these days on ebay.

You dont have to bore your 998 to get it more power, the work needed would cost a small fortune anyway. What you could do is work on the head. The smaller engines can produce some good power but most of that comes from head work anyway. The rule of thumb to remember is an engine is like you, it needs to breath. Having the inlet ports opened and some valve work will get your 998 screeming on its own, a good LCB and a nice set of twin 1-1/4 SU's will have it running well, and a cam into the mix and get the final drive sorted will have it competing with some 1275 and 1310cc boys anyway. And in my opinion and it is only an opinion, its much better to be keeping with people who have 1275,1293 and 1310 all day long and when thay stop and ask what you have, just watch there face whan you say 'OH only a 998.'

The 1275 engins can be picked up for about £100.00 or so these days on ebay.

Can't say that I've seen them at that price recently, normally nearer the £200 - £300 mark in my experience. The surcharge on a recon unit is usually around £150 these days, so any cheap engines will tend to get snapped up by the remanufacturer. If you do find a 1275 unit for around the £100 mark then you might have got yourself a bargain, but I'd also be wary that you haven't bought yourself a heap of scrap metal at that price. There are a a few lemons being sold on ebay, so whatever the price try and get one that is still in the car and can be heard running, there are still a few A series metro units sitting around in old scrapped metros which could be a good bet. Better still keep your eyes open for an old metro MOT failure that someone is trying to get rid of, buy the whole car and remove the engine, you could even make your money back by breaking the rest of the car and selling the parts on ebay. A-series metros are a bit few and far between these days, but you could get lucky and still get yourself one with a decent engine with reasonable mileage.

Not sure where everyone has been looking, yes fleebay can produce a few bad ones but, i have now had 3 1275's in the last 3 years and only paid 100 each for them. Maybee as you said ive just been lucky or maybee its because when i go looking for one i dont just stick to the forums and ebay like so many people do. The internet is a huge thing and by typing things in the search bar such as ' 1275 cheap engine, or bargain 1275cc engine, or even 1275 engine (followed by town names near to you) will produce the goods that you want at the prices you want to pay............. even sites like 'Find me a cheap ?' can also be a good resauce for engines. Also try looking in small village garages and workshops, you will be amazed at what the older mechanic shops have tucked away under tarps in a shed.

I've just spent about a month looking for a 1275 engine that wasn't on it's last legs and the best I could get one for was £200. That was with no ancillaries either, so if you do find an old Metro ("used to be owned by an old lady who only used it to pop down the shops once a week") with a 1275 engine complete for £100 in a scrapyard as everyone else seems to be suggesting, you're very lucky indeed.
