the reason behind the 1098, was because i have this available to me today as it were, as soon as i take it out of my estate thats being scrapped that is, i could just not use it and wait and put it in my pickup in just standard form after a through checking over of course.

I have been broading my thoughts past the 1380 idea for the same reason as you mentioned, i found that the 1275 head bored out would not be strong enough to take the pressure i would be looking at running so have been trying to find other engines to satisfy my needs, i know that the austin minx 1750 e series was a favorite transplant many years ago and these engines can also be found in the alegro, they produce the same power as the metro turbo in standard de-tuned form, alternativly i had thought of the rover 216 (around G reg) i owned one of these cars years ago and it has to be the best engine i have ever owned, being made by honda it is a all alloy block thus light weight, comes with a 5 speed box (always handy for motorways) and is fuel injected, the cars are also pretty cheap to buy aswell, i picked mine up for around £200 i think, 1 problem though is that i don’t know if it would fit, not having owned it for at least 6yrs i can not recall if it was a big engine or not, or the layout of the engine/gearbox

your thoughts??? i’m not sure i’d be able to fit a charger but i’d certainly look into it depending on power outputs (which i can’t find out at this time either)

would it be possible to contact you directly, you know your stuff and i would hate to gum up the board on a non supercharged tangent

I think 286 is probably a little too much overlap for blower on the road, not sure about the swiftune though, stage 3 head sounds good but you need to ensure that you have the largest possible combustion chambers which means don’t skim it more than is required to clean it up. Flat top pistons are probably a big no no as you need a deep dish piston to lower the compression ratio to around 7.0:1

I have a 3.1FD and find that with the extra torque it wheelspins in first second and a bit in third on 12″ wheels with yokohama a539 tyres. When I get the chance I might change it up to 2.9FD as it screams along at 4000rpm @80mph at the moment!

The main problem with supercharging is that you need to lower the compression a lot to stop the engine knocking, I have managed to get mine to a reasonable level but have still had to fit an intercooler and water injection to get it to run reasonable amounts of timing advance to run off boost nicely.

I was wondering why build a tuned 1098 at 54bhp when a standard 1275 can easily give 56bhp, is there a shortage of available parts in your area? If I wanted a good engine to start with then I would use an MG metro turbo lump and rebuild that but it would have to stay to standard bore sizes as the 73.5mm(1380) doesn’t leave enough meat between the bores to take the boost pressures reliably. The other good thing with the turbo engines is they have sodium filled exhaust valves and slightly better sizing on some gearbox parts.

It is always fun making things that are different so keep at it and have a look over at alt.autos.mini newsgroup if you have any problems as there is always someone who can answer a question, however silly it might seem to you!

taken a look at your site, very impresive i must say, i hadn’t thought about the gearbox as such, i had planned to fit a SW5 cam or Kent 286 cam with a stage 3 head and flat top pistons, i had planned on running this through a possible 3.1FD am also planning on lightening and balancing the flywheel.

I wasn’t planning on buying the kit but rather build it, i think i can do i can buy the parts cheaper seperatly over time, and the engine modifications would set me along the way whilst getting the parts together.

of course i could do the proposed mods only without the supercharger and build myself up a nice charged 1380, i would be able to sell the 1098 in it’s tuned form quite easily as i belive it would pull around the 54bhp with over a 50% torque increase

My friend has the vmax blower and his mini produces 160bhp! poor old gearbox!

I have almost sorted my traction problems now! I have stopped it from wheelspinning in third by only taking the mini out in the dry!…………..

check out my website and have a laugh at my long minivan!

The vmaxscart kit sits on an inlet manifold at the rear of the engine, so it is really a bolt on goody!

do a google on it and you should find some good photos!

After recently having to take my daily driver off the road and reverting back to the trusted mini for a good few years i am looking at going the supercharged route now, i was wondering if the charger could be mounted at the rear of the engine like the shorrocks were. can anybody shed some light on this, i think the front bulk head cross memeber might foul the install making it impossible without redesigning the cross memeber completly, something i don’t fancy doing myself.

thanks in advance

If you really have to keep the engine then I suppose the best places to start are the places which cause the most restriction to power output.

Without hurting your wallet too much I think you would be safe with a stage one kit comprising of a good inlet manifold, lcb exhaust manifold, rc40 exhaust system and a needle for the carb, as you have the filter I think you should be ok, although I have always found that a K&N filter in the mg metro filter housing is superb!

Anything more than that will start to cost money and involve engine rebuilds, although a high lift rocker set works pretty well and can just be bolted on if your valve springs will take it at full lift without binding.

Next on my list would be cylinder head and cam!

I would seriously consider putting in an MG metro engine as these things standard will produce far better torque and power than you could hope to sensibly achieve with a 1000cc and you could always go 1380cc later if you fancied it.

And before anyone asks, yes it is a very easy engine swap to do and all the parts interchange pretty well!

If you want to read a book on engine tuning for the A-series then I can thoroughly recommend Tuning the A-series by David Vizard, it is very informative and will help you to build an excellent machine!

Hope that points you in the right direction!

I have a classic austin mini-1000cc engine & the only thing i have done so far is install a hi-power air filter.i tried your link but it did not work.

waiting for your response!

I think you will find that there is already one fitted! Although it will not be one of those boy racer noisy things as the S has a supercharger it needs to use a recirculating dumpvalve(bypass) which basically returns the boosted air back into the inlet side of the Blower when the car is at idle and decellerating.

So in short no! Although the MINI isn’t really that short is it to be fair!

I hope that helps!

I was wondering if Miniman could let me know where he got the multi v belt pulley, my single v belt one needs replacing anyway so fitting a blower ready item would be a good idea.

Thanks
