Hi all,

Im at the edge of starting my own project.
Im owning a 2005 mini one (which is a european cooper version with only 90bhp, but the same 1.6 base engine), which I became attached to.
Simply said, I do have the money for an s, but I dont want to trade in my own mini. Besides, my mini is without airco, so I want to install that as well!

What i also do want is MORE BHP!

So, what do I need,
- cooper s engine
- cooper s gearbox and shifterbits
- cooper s driveshafts
- cooper s hood

At the moment, I know where I can get all the parts (have some adresses here). For instance, the engine I want to use is complete with ecu, wiring, etc, and has done only 15000 miles. Good as new!

Ill try at first to keep the battery in the front and relocate the intake, but well see.

Im really looking forward at doing this project.
At the moment Im still searching for an airco-unit (so, if you have one or know one hanging around, let me know!) and a company that will help me install both (maybe the dutch m7 ditributor will provide help??)

Just wanted to let you know that there is an idiot somewhere whos really going to do it!

Greets from Holland,
Sid

This guy on here is trying to do it too but hasn't posted any updates on his progress. Keep us posted with details and pictures. I only know of one guy from Manchester that did it a few years back. Have fun with your project!

 

I recommend keeping your MINI One as is. Spend the money rebuilding a wrecked S which I'm sure you can find, or even better restoring a classic Mini S.

 

ehm...
no

 

Angenaam Sid,

You're taking on one BIG project. Vel duur ook mijneer.

 

thats true, but hej, I like a challenge like this.
Its doable, it has been done by several in the past, and I think it would be SO cool.
selling my mini just isnt an option, it has special value to me.

 

So you don't drive this car every day at the moment?

 

I put 20000miles on it every year, but thats just why I want the s engine, and not some aftermarket turbokit.

 

what's the time line for your project? Do you have a budget?

 

the deadline is end oktober/begin november this year (but I want the complete build-in completed in about a week).
the budget is 5000 euros (around 6500 USD I believe), but Im trying to keep it below 4000eu.
The engine and gearbox will cost me 1500 euros, the rest is for driveshafts, airco, bits and pieces and labour.
Maybe Ill get the airco for free!

 

Why dont you wait and put a 2007 turbo S engine/tranny since you are going through all the trouble. Better mileage and a lot more fun than the SC.

Question is how soon you think someone will wreck a 2007

 

well, the s engine is a pretty basic swap, since the engine Im purchasing has everything I need.

I only need to buy from the dealer:
- driveshafts
- hood
- shifterbits
- maybe a s-radiator
- some piping, wires etc

and after this, try to get my dealer or M7 so crazy to help me

 

This is a project that I have looked very seriously myself. I want to put an S engine in my cooper.

You mentioned trying to keep the battery in the same place, I think that is very possible if you install a M7 AGS, is moves the entire intake assembly out of that area so you should be good to go.

Keep us posted on the project, I am looking to do this once I get out of school, I really want to find a way to keep the cooper hood for a real sleeper look, I have a few possibilites that I am looking at right now

 

please share all your ideas so that we can all make it work
I found the m7 intake as well, which Im planning on using too.

only I do think Ill be using the s-hood, since its ''only'' 300 euros (about 250 USD in america I think?)

Ive got prices from my dealer as well:
- driveshafts left and right, together 700 euros
- gear shift lug 80 euros
- engine wiring harness 200 euros

I do hope the engine I want has the wiring harness still in place. Ill be looking at it next monday or tuesday, and will take some pics

Im also thinking about keeping the 5speed getrag unit, since they will take up to 150bhp without problems, but 163bhp and more torque (cause of the sc) might kill it... plus, when doing an engine swap, the gearbox isnt to much extra work anyhow

 

Ok, been in touch today with the biggest bmw tuner in the netherlands.

they really know what they are talking about, and
GUESS WHAT??!

they said that the complete engine swap isnt worth it...

why?
because the cooper engine will take up to 170bhp without problems! this includes the getrag 5-speed... the only thing you really need to do is to mount an oil-cooler (which is like 80usd, pff).

so, what should I do?
next week i have another appointment with them, and Ill be suggesting to mount the supercharger and intercooler bits on my engine, mount the oil-cooler, add an s-hood, lower the compression from 10:1 to 8:1 and custom-remap it so that it will run nice and smoothly...
this will save me like a grand!
the difference between the coopers and s's crankshaft etc...all completely unnecessary when not passing 170bhp.

Ill let you guys know.

 

Wow, that would be kinda cool. What about the water pump??

But the question is once you convert to an S, will you want to keep it under 170hp

Nik

 

the waterpump on my cooper engine will be replaced by the sc which has the waterpump attached on its other side

 

where would you get an oilcooler from??

 

 

I have thought about upgrading the cooper engine myself, but 170hp, Im young I want more power than that. Im looking to have 260-300hp mini

That is a thread I started on another website, the comments have pretty much stopped but it was going strong for a while. I would love to do this project but for me it would be cheaper to suck it up and buy an S, I have sadly come to this realization I'm trying to decide if its cheaper to do the swap or buy an S and twincharge it. I cant settle for a normal mini

 

how are you going to lower the compression?

 

the cooper pistons are flat. you could lower the compression by sticking cooper s pistons in there im guessing?

 

this definitely has got my attention been looking to get a CooperS engine from somewhere & have the conversion done

 

I was thinking about this last night for the first time and then found this post today. (how Crazy is that!) My thought is to keep the stock MC bonnet so that you have a sleeper. The solution that I have is to use a water-to-air intercooler (ie....the Mini-Madness intercooler). The water is cooled at the front of the Mini rather than on top of the engine so you do not need to have the opening... (I could be wrong though)
Just my .02 cents

 

Im back!

shoo, much has happened the last few weeks.

First, I went to take a look at the s-engine. The guy said it was a perfect engine, so I bought it for 1500 euros. I scheduled to pick it up a week later. Then the next day the phone rang. It was the guy who was selling the s-engine. He said he had a man who really wanted the engine and was willing to offer me 1000euros extra (thats like 1200 USD)!!! well guys, Im crazy but Im not stupid, so I took the money!

At the moment Im looking for another engine.

The list of parts youll need for the conversion:

- engine and gearbox
- driveshaft left
- driveshaft right
- shifter cables (2 pieces)
- engine mount
- s-bonnet
- custom air filter (like an K&N or something)

Then youll have to take the cooper-engine-wiring-loom and put it on the s-engine. This is because the s and cooper have different plugs.
The injectorplugs are different as well, but this can easily be sorted with another plug between the loom and injector itself.

So, Ive got it all sorted out with the help of a professional tuningshop, but Im looking for an engine again at the moment...
