WANTED: 16V A+ SERIES BUDGET INFO.
JONBEE - 6/10/08 at 07:16 PM

Hi ladies & gents,
i've been looking at the 16v conversion options for the A series engine.
HOW MUCH!!!!! £6K done, or £3k for parts!!
The car is not worth anywhere near that.
But i like something different.
Anybody got any info on the scrapyard / breakers conversion for a 16v A+ series 1275.
i emphasise A series. no rover k 1.4,1.6, 1.8 , or zetec etc.
Thankyou
Jon

NB: now i'm staying with the A series in the moggie, i have a MT75 rwd gearbox from a 1990 2.0 dohc sierra. mileage is unknown, but was told it was very good when recently purchased. £40 ovno or will do a deal with a low mileage 1300 maestro engine, preferably with the ancillaries.
message me if interested, and i'll return my contact number, unless i can call you.
thankyou
Jon

Hows about the 16 head off a BMW motory bike? Seems a popular conversion.

Haven't we already had this discussion (or one very similar)?

The £3k, £6k option is for the bmw k1100/k1200 option from well known tuning shops (minis)
slightly cheaper for 8V !
I have short arms and very deep pockets , with very little in the pockets.
More info if you can please.

Mate of mine is going the BMW head route.

Head from a K100RS (ideally as it's got long duration cams) try this place for one Motorworks
IIRC about £350 for all you need head, TB's etc.

And this place Specialist Components for everything else.

Edit to add.......
If you do a lot of the work and source fabrication etc it can be done for much less than 3K

Fine if you are building an engine to fit in a particular class ie some of the Mini classes where you have to retain the Min block and transmission but totally crazy for any other purpose.

Of course you would have to spend money on the bottom end to make it cope with the RPM a 16valve heads needs to produce decent power ---

If you look around there is a lot of more conventional A series tunning gear to be found -- you never know you might find an 8 port Arden head.

A lot of work certainly, but I don't think it's totally crazy. To get significantly more than a genuine 100bhp with a 5 port head you really start sacrificing driveability, idle quality, economy etc. An engine swap is a lot of work with custom driveshafts, subframes, often bodywork mods etc.

The bottom end of a 1275 is pretty strong anyway, the Metro Turbo in standard form was safe to 7000RPM for brief periods as advised by the handbook. With a center main strap and shot peened rods etc. the bottom end can be made very robust.

Here's a DIY guide to the BWM head conversion, the only 'cheap' option.

The KAD or JKD heads are both insane money.

On the whole doing DIY subframe mods to fit a 1.3 Nissan Micra engine (with a good intake/exhaust it makes Suzuki GTi power) will be cheaper, lighter and give you a 5 speed gearbox.
