Car Forum / MINI / February 2004Mini Donars
I am the owner of a 1977 mini panelvan. My father is looking at geting a project mini its a Morris 1000 Deluxe i think... anyways, i feel he may want disc brakes on the front of his new mini (when it gets to that stage) but i know that reconditioned cooper discs cost alot ($1500 up) so i was wondering if anyone knew of a similar car that these could be used from. Maybe a dihatsu charade? i vaguly remember hearing of machined civic brakes, but im not sure. Also, would the power assisted braking unit be transferable? Personally, i would like to see if i could get a 5 speed gearbox. I know most people go for a better 4speed, but i like the current ratios for around town, i just need 5th for highways. Are there any gearboxes that will fit onto a mini engine with slight modification? i remember the v8 minis use a 'princess' gearbox. I have no idea what a princess is (not in australia) but im guessing its in the sump, and so is this transferable onto the 4cyl? maybe a van box? i am not sure. One more thing. Injection systems. I love carbies dont get me wrong, but if i could get an injection system that would be great. Im pretty sure (i dont know a lot abot injection) that ill need a new head for multi point injection, but wouldnt for single point injection. Anyone know of a transferable single point injection system? and what is involved in installing it (eg sensors, inlet mod?) Thanks for your time. Regards, Mik Where abouts are you? If you are in the USA, 4th on a mini should be more than long enough for cruising. Mine revs less than most modern cars in fifth at 70, never mind 55!!

However, if disks are too pricey you can try to get hold of a remote servo and fit that to your existing brakes that will help. A princess is a really ugly looking british car that is very wedge shaped..I couldnt tell you if the gearbox fits a mini box but at a guess it would be an A series or B series engine and gearbox. I think it the B series with rear wheel drive like an MG BGT so you would need to do some heavy floorpan mods. Both the single point and multipoint injection systems have the injectors in the manifold not the head but you would also need to change the cam/flywheel/end engine case/starter motor/petrol tank as well as rewiring the car for the computer and sensors and fuel pump etc. I threw my SPI stuff away from my cooper as it is crap, Its not really fuel injection anyway more like an electronic carburettor. Stick with carb or carbs unless you are restricted by emissions laws. fragged > I am the owner of a 1977 mini panelvan.

Being front wheel drive complicates a conversion somewhat. > Also, would the power assisted braking unit be transferable? Yes. It's called a "VH44" and was also used in many early Holdens, Chrysler Valiants and possibly Falcons. It was pretty much THE compact single line hydraulic booster of it's day in Australia. Any Aussie brake specialist will know what a VH44 is. > Personally, i would like to see if i could get a 5 speed gearbox. $$$$$$$$ > Are there any gearboxes that will fit onto a mini engine with slight > modification? Not even nearly. Consider how the Mini motor and gearbox fit together. It is completely different to almost any other front drive arrangement. > i remember the v8 minis use a 'princess' gearbox.

No, it's completely different to the Mini A series. > maybe a van box? i am not sure. The Mini Van, like a Moke, is just a different way to join all the mechanical parts of a Mini together. The gearbox is no different. > One more thing. Injection systems. I love carbies dont get me wrong, > but if i could get an injection system that would be great.

Anyone > know of a transferable single point injection system? and what is > involved in installing it (eg sensors, inlet mod?) This would be a major job. The easiest approach would be to buy an imported injected Mini motor or complete Mini. Even the last injected Minis were only a two point system since there are only two inlet ports on a Mini head. Yeh thanks everyone. The power assisted braking unit number should come in handy. I thought the 5spd gb would cost more than the 1000pounds.. ive seen em for like 3000pounds before... I think ill forget the 5spd option anyways. More power and a bigger diff if anything. The only reason i ask is because i travel at around 100 (4000rpm in 4th) on the highway.. but thats floored. i wanted to have a bit of overtaking power. As for the brakes. Ill start looking myself. i dont really trust drums all that much, and they'll need an upgrade if we work the motor anyways. The Muffin Man, i never said my motor over reved at 55. But i do believe it revs much higher than other cars going the same speed. Maybe you are refering to the mini in 4th and the other cars in 3rd? im not sure. I find the need for another gear almost all the time. (tho i would prob get in trouble for going too fast) Anyways, thanks for everyones input. Ill let you know if i find out anything else. > I thought the 5spd gb would cost more than the 1000pounds.. ive seen em > for like 3000pounds before...

If you're using full throttle at 4000RPM to do 100kph then raising the gearing so that you're only doing say 3600RPM is only going to make matters worse. > As for the brakes. Ill start looking myself. i dont really trust drums > all that much, and they'll need an upgrade if we work the motor anyways. Mini front drums are pretty revolting objects. But thats the very reason why disks are so expensive. i dont understand: "if you're using full throttle at 4000RPM to do 100kph then raising the gearing so that you're only doing say 3600RPM is only going to make matters worse." Wouldnt it make matters better in the scope that you can now travel at a slightly higher speed, giving you more control (rather than having to max it out, and the only option is to slow down) ?? i know the acceleration suffers, but im not sure. I have twin carbs sitting on the shelf that i can fix up and pop in.. giving me more power to use with a bigger ratio diff.. but i might b donating them to my dad now. Anyways, thats the reason for me asking about the 5th gear, its just about highway travel (since im going to have to travel a lot more this year, and i dont really want to get rid of the mini) ill just bare it. it isnt all that bad to travel in.. im just glad i havent driven it with a hang over yet (the vans reverberate the exhaust sound more) Anyways, cheers. > i dont understand: >Graham wrote: >> "if you're using full throttle at 4000RPM to do 100kph then raising the >> gearing so that you're only doing say 3600RPM is only going to make >> matters worse." > Wouldnt it make matters better in the scope that you can now travel at > a slightly higher speed, No. The power available at full throttle generally increases with engine speed to close to redline, then tapers off slightly. If you require full throttle at 4000RPM to do 100kph, then by changing the gearing so that you're only doing 3600RPM, you will reduce the power available at full throttle. The car will not reach 100kph. You can do a practical demonstration of this. Find a long steep hill, one which you can drive up in third gear with near full throttle at a particular speed. Change up to fourth. You will no longer have enough power and your speed will fall off. AH yeh ok. but i thought that since the car kinda redlined at 4000rpm.. like in every gear.. that it would be able to use that power. like mine is maxed at 4000rpm in 1st, 2nd and 3rd.. and also.. the highways are all fairly level. THO..i wouldnt be able to use 4th as much just crusing up a hill like i do now. Hi, If my mini redlined at 4000RPM, I would want to find out what was wrong with the engine!! Keith by memory, compression is allright and all. its just the carb and timing... which is prob way out.. i do stuff by the book.. but i gave it to a mechanic once who tuned it .. and it ran good.. but the main prob was it didnt run under load,... which ended up being a fuel pump prob.. so after i fixed that (and had replaced the electrics and swapped the carbie around a bit), it was back to untuned.. so i got it running.. but not too great. ive gota get hold of a fuel air mix guage i think.. because i am pretty sure the needle is wrong the numbers are worn off the needle atm (i THINK.. ) but my setup is a: 1098cc 1/2" SU extractors which are barely any different to normal manifold. (got them for $10) 1 3/4" exhuast (from manifold is there anything else you need to know? everything else is standard. thanks > The Muffin Man, i never said my motor over reved at 55. Neither did I. But you also didn't say where you are from, you just talked in dollars, leaving many possibilites. > But i do believe it revs much higher than other cars going the > same speed.

(tho i would prob get in trouble for going too > fast) What I did say was that my motor revs at 3300 in 4th and most modern cars rev 3500-3800 in 5th at 70mph on a motorway. The Muffin Man weird. My motor would be going approx 80-85kph at 3300rpm in 4th. You saying that you get 70mph in 4th at 3300rpm is completely strange to me, that is equal to ~112kph, a speed i cant get out of the mini without a nice downhill slope. I believe all this is just a misunderstanding, most probably on my behalf. and appologies for not stating the country. > But you also didn't say where you are from, you just talked > in dollars, leaving many possibilites. Somewhere in there he mentioned Australia. |
