Hello i'm just wondering if there is a mini with anything like this and if so what is the best place to get the parts from.

Also has anyone got any pics of an engine like this?.

Originally i was going to supercharge a standard 1400 and try to fit twin su carbs but from what i was told it would be very hard. As i live at work with no bills, girlfriend etc... money is not really a problem so i thought an 8port would make it easier to mount them?

cheers se

That would be interesting...

However if money isnt an issue, how about a 16V KAD engine, with jenvey injection? Force racing turbo'd theirs, stupid amount of power...

[burnz24]

with money no object you have no end of options..
the above options would be great, if it has to be supercharged then a rotrex supercharged 16v KAD/specialist components engine with a loopy parts list..
just remember with no budget you can quickly run up massive bills and end up with a car/engine that is both undrivable at low speeds and dangerous at above that

KAD 16v!!!!!! i said money isnt really a problem not i'm rich enough to buy a racing engine every month lol.

i've heard the life time on these are only around 4k miles road use??? or am i wrong?

That is the idea burnz i want a car to take to shows and back and that is about it... i have my daily mini then the one that is being refurbed atm. with the amount ive spent i wish i waited for a mk1 cooper s!!!!!!

How about a bike engine conversion ?

[se_juggles]

hmmm just had a complete front end, boot/seat pan and a new floor welded in. All heritage :s so probably piss the welder off if i asked him to cut a hole in the boot floor.

The reason i want to do this is... its something i've never seen before. I'm a big fan of the weber carbs and 8 port heads so its just something to stand out and impress. Hyabusa's are fast but *yawn* its just another conversion i've seen to much of.

Promotive conversion. No cutting needed. Its all up front.

I wouldnt bother with twin webbers if you are using forced induction, you dont need a big powerful carb when you are forcing the air in you just need a carb that can supply the required fuel amount,

If it were me I would look into a charger, and 16v head of some kind, 1293 with uprated bottom end, make it a fairly hot engine but still driveable.

dual twin webers look soooo awesome though!

the power is not a thing i want really... i just want it to turn heads... the car will be in the garage around 99% of the year.

[Alex_B]

If its turning heads then I wouldnt bother withe supercharger, fit twin 45s and have straight cut drops, with a big exhaust ( not chav spec just a larger bore) on an 8 port head so the webbers are at the front with a nice set of filters that can be taken off when at shows as trumpets look yum!

[se_juggles]

Thats the look i want to go for. but again its been done to much i've not seen this setup supercharged.

Firstly if you are fitting an 8-port then bin the idea of carbs. You have 4 separate inlets, the best and easiest thing to do is put a plenum on, a single TB and inject it. Also, don't spend all that money on a fancy well specked head and then ruin it by bolting on a crappo M45 charger. If you must supercharge, build a high comp engine and use a Rotrex, otherwise turbo would be the way forward

The issues I perceive with charging an 8-port are as follows:
1) there is no cam available off-the-shelf that would be suitable. so you'd need to comission one, would only be a few hundred pounds, but you'll need to specify the profile.
2) How big can you get the chambers in the head, 26 to 28cc would make life easier when choosing pistons
3) If you turbo you'll need a manifold made, again, not a big deal but will cost a few hundred notes.
4) Make sure you buy the non-race 8-port with the smaller valves

[mini13]

what he said ^^^^

my sugestion would be to use the specialist components 7 port head (as wil above has done) as you'll be able to get a turbo exhaust manifold off the shelf, and also a plenum.

[MIGLIACARS]

i have a 7 port supercharged with a rotrex blower on it. webbers are not the best idea, i use a dta fuel injection system so its very drivable. webbers are not the easiest things to get running nicely and will be lumpy down low.
i had a special cam made up for it.

if you are serious about this and have some cash available mbe will do it for you, they did mine and cannot fault it. mike really loved doing this installation, and has talked about doing an 8 port.

[se_juggles]

hmmm have you guys got any pictures??...

i know carbs are not very reliable especially webers but there tidy and look the ********.

how much did your 7 port supercharged with rotrex cost to do miglia???
