Well I haven't heard a great deal about them from people who have run them, but I'm sure I've read a couple of people who weren't overly impressed. I do know that they went to several top engine tuners to develop it (Bill Richards and MorSpeed for two) and they both wouldn't touch it, I believe because MiniSport wouldn't allow anyone to put their name to it. So they developed it in house.

Why not go for the BMW "K" Head?

8v is just as good as the 16v...
Spoke to Simon about doing the 7 port thing, basically, getting the head, and then getting him to properly sort it, and he said the 8v is a cheaper, and more powerful engine!

Ok you can't use the bottom end bit as standard on a A series, but Simon quoted me...

a 1380, with all the toys on...
proper injection system
300* cams...

I could quite happily see 160-180bhp!! thats from a 8V!! the 16V is a little bit more...

Hmmm, not sure the BMW head would be cheaper. The one major plus point the 7 port head has over any other 16V or 8 port head is that you can use a lot of existing mini parts with it, exhaust manifold, etc.

But I'd admit, if I was doing this project, I'd serious consider the BMW head.

[andywaller]

well i did consider it but when you take into consideration that i have already hundred of pounds on cam, vernier timing gears, rockers, springs, pistons, exhaust manifold, rocker cover ect. its starts to become less of an investment!

and to do the k1100 properly not just whack it on and get it running would definately cost more than the 7 porter would, even before i consider the time to buy/ make all the custom parts!

im really stuck now, im not going to go the k route as its just too expensive for me in terms of wasted parts, if i was going to start agin on engine spec id rather pay a visit to KAD and get things done properly!

so if i dont go 7 port i would have to look at something along the lines of miglia spec!

[andywaller]

right price wise for a specialist components kit id be looking at

£1385 which would get me

head and trottle bodies
conversion kit
trigger disc
exhaust manifold

to this i would need to add the cost of ecu about £600

and also i few hours machining

also i would need a front mount rad and various bits and bobs


7 porter is going to cost less but yeah wont be as much power.

[Dave 1293]

stay 7 port... your cars light... its guna be quick anyway

[wobblybob]

tbo anything over 120bhp is just wasted power it'll just spin,save some money, save a bit less stress on the engine and run at about 100bhp u'll get the same 1/4 /0-60 times as the 120+ one as u wont be able to use all the power so wots the point in having it?

[Jammy]

You can easily use more than 120 bhp in a mini, and the extra power certainly will bring the 0-60 times down, just ask the Vaux/Vtec lads!

I'd say, at this stage stay with the 7 port! Then if you don't have enough power, look at doing something a bit trick with it, be it Megasquirt, forced induction, NOS, etc.

Seconded...

[andywaller]

cheers for the advice i think your right, i will continue as planned.

its going to have ITBs and a mappable ECU anyway so the fueling will be sorted.

and if that doesnt deliver the goods i will turbo the little bugger!

[andywaller]

well i had a busy weekend on the car and can now say i have finished all the repair work welding now so its onto panels in a while. i still need to dress a load of welds that i did on the car and also prepare the sills so they go on nicely but thats it!

so i hope to get that done by the end of the week end and its then off to the sand blasters!

i also scraped off all most of the undersill, thats a nice job! NOT. need to tip the car up the other way to finish that!

i spent this evening with the dremel smoothing all the internals of my block, i can now say that the oil is just going to glide staight back into the gearbox so easily! looks trick but you will never see it!

so here are some pictures

[wobblybob]

use a grinder with a wire wheel, its will get the underseal off so easy, i did the whole floor and arches of a cooper s at work in no time back to bare metal, comes up much nicer

yeah the whole floors going to be sand blasted so it will all go anyway, just needed to get the worst of it off.



i modified my hi los at work this afternoon so i will now be able to lower the car another 15mm more than before, as i had the adjustment bottomed out and still wanted to go lower.

A 5 port 1380 with decent stage 3 head, mappable ignition and throttle bodies will easily reach 140bhp so I think 150bhp+ is a very realistic target
.
However, I think this "£1385 which would get me
head and trottle bodies
conversion kit
trigger disc
exhaust manifold"
is very optimistic. the head alone is £1300 and the head has a cast inlet manifold, which is very short and designed for weber 40s. - this is the only way it'll fit under a bonnet that doesn't look like you've stuck a bread bin on it, so to achieve mappable ignition you'd need £1500 for a weber alpha kit (which includes everything tb's trigger disc ecu etc)

Ok sorry for this, but I'd love some more info on this!

and MOWOG... 15mm!! Can u reveral how youmanaged to do that...
