Jay - Luv that gif. I stole it...hope u don't mind.

 

I totally agree that these gains are possible but there is several concerns I have. Certain parts of the engine can handle that much power, some not, only time will tell and show the longivity of the engine. The big concern I have is the gearbox...Plus you would most likely need an LSD on this which would most likely add a fair amount of torque steer, and please correct me if i'm wrong but I thought an LSD also was harder on a gearbox but I need to double check that(anyone know for sure?) Also you would have to have a stress bar in this and other items to reduce chassic flex...this just isn't a matter of bolting on a turbo, there is several other things that you would have to do.

But only time will tell on these types of conversions.....so when is someone gonna jump in and ask if this voids the warrenty?(hehehe - that was said with heavy sarcasim)

Which one, the BS meter? :smile:

I stole it too! Woohoo! Share! :smile:

 

>>I thought the wankel took up an enormous amount of space? I could be wrong, but when you look at the skeletal pictures of the rx-7 and rx-8 the wankel and tranny take up a huge amount of hood real-estate. I wonder how you could stuff that into a mini. Would be sick though.

Actually, I think a Wankel is SMALLER. I could be wrong, but just the "block" is about 3/4 the size. If you're talking about the length, yes. But remember, the RX-? series is a rear drive.

If you look at just the dimensions, it will slide in with room to spare. Even with the Getrag. I don't know if it will bolt up to it but just the physical space is NO problem.

Here is a photo of an ear-shredding kidney-rupturing 645HP RX-7 Engine.

Now do I want a 645HP Mini? No, but a dependable, driveable 250 to 280 is not only realistic, it's conservative.

Can someone with more techie experience and know how address this?

here is my 2 cents.

Is it possible...YES

Will it be reliable...Maybee, maybee not. I have seen allot of turbo cars built and most tend not to be daily drivers, and soemthing pushing that much power will have its share of stupid little problems.


Can't wait to see it.

These are my opinions and I am all for a Turbo Cooper S.

 

Here are the stats on the new RX-8 W2 engine. I can't find the weight though. Also, this is a NON TURBO version. (tail wagging)

Engine
Type: W2
Displacement cu in (cc): 80 (1308)
Power bhp (kW) at RPM: 240(176) / 8500
Torque lb-ft (Nm) at RPM: 155(211) / 5500


Here is a picture of the RX-8 Engine:

I love the RX-8 in the blue color. Like X2. Very saucy. They say it handles like a dream too. It will be a classic without a doubt.

So many cool cars on the road now.

 

It could be possible but I am not going to belive it till i see the system.

The MINI's engine could probably take that much hp. It seems to be overbuilt and has all the go fast goodies needed to sustain that much power.


If you want to see a motor that is really overbuilt go look at a Nissan SR20DE motor used for many years in various forms in both fwd and rwd cars. The motor made around 150 hp stock depending on the type of car it went into. The stock internals can take some where in the 500 hp range and still be very reliable.

 

>>Hmmm, why is there no discussion of a turbocharged Wankel engine for the Mini?
>>
>>I still think this would be the magic silver bullet.

Hmmm, a Wankel engine would increase length of the Mini by a foot or so if it were a rwd car. As a FWD car it would be darn near as wide as a Hummer. Mazda would have the market on quick cheap cars if it could make a FWD Wankel practical. A 1.3L twin turbo in a protege' would make for a hell of a car.

 

>>I thought the wankel took up an enormous amount of space? I could be wrong, but when you look at the skeletal pictures of the rx-7 and rx-8 the wankel and tranny take up a huge amount of hood real-estate. I wonder how you could stuff that into a mini. Would be sick though.

>>Now a K20A in a Mini would be an incredibly sweet thing. That RSX-S engine is a true jem and a half. Heck the new detuned 2.4 in the TSX is a beauty too.
>>
>>I still find it hard to believe, but you wouldn't see me complaining if you proved me wrong. In fact I would welcome it.
>>
>>Someone I think that much power on a FWD car would effect daily driveability slightly, but I would love to hit a nice, reliable, controlled, and non-lagging 240-250 hp. :smile: Is that asking too much? Is mid-12's in the 1/4 too much?
>>

>>Rofl, would love to see the look on the service man's face as he chokes after opening the hood too. :smile: Even better with iVTEC!! Lol, get your car serviced at an Acura dealership! Now that would be trippy stuff!

Actually the wankel rotary may appear to take up alot of space in the new RX-8, but in actuality its quite the opposite. A better example is an RX-7...take a look at the 3rd-generation RX-7's for example. Because of the enginess small size, it allows it to be placed further back in the chassis, making it in essence a front mounted mid-engine car. This is a big contribution to its 50/50 weight split. Now...just imagine, with how amazing a new Mini cooper handles stock, and give one that weight distribution!! The wankel 13B(2-rotor) displaces 1.3 liters,and weighs only about 250lbs and is so small you could probably fit two of them in most cars...but it packs alot of punch. So if someone were willing to take on the project of installing one in a new MINI, the hardest part would not be where to put the engine, but how to make an adaptor for the transmission...as I scratch my head

It all sounds sweet, and I am all for turbo upgrades, but I am not going to jump on the wagon yet. As far as the engine being bullet-proof, if it goes, are you going to buy me a new one? It would be a ***** and a half to drive all the way down to FL just for the install. Did you mention when the power would kick in? You need to keep that number as close to the stock supercharger number as possible. People aren't going to want power to start at 5,000rpm. Show us some factual testing/long term testing and I will think about it. 5-6k for an upgrade is no chump change...

 

I can't wait to see what the results are when this car is "extensively modified and wheel-hp dyno tested". That should make it fun in road-mph driving.

 

I am sure that the system is entirely possible. I think it is also quite silly not to modify the internals. I think it was 2 seasons ago when a well known import tuner released a turbocharged AND supercharged Integra, using supposed stock internals, into the drag racing scene with relative success. I forget who the tuner was, but the supercharger was an eaton roots style from Jackson Racing, and I think the turbo was an HKS unit. This beast boasted huge power, laid down serious numbers, and was featured in one of the 2 major import magazines (either SCC or SS) so it is possible. I have not seen that car since its debut season. Take that to imply what you may.

 

We will definitely test this system over time, at least 5k miles to work out any initial bugs, I tatally agree with those of you who think of the 100 little stupid things that go wrong, because its just a given with custom projects of this nature. We will do some track events, and deinitely some road-mph testing too, the dyno is good to a point, but the road and mph certainly doesn't lie. I think we are on the right track because the kit won't see the market until at least 8-10k miles of reliable performance can be had.

To answer the question about install/what the kit consists of, The kit definitely will consist of more than just bolting on a turbo and letting it rip. The main components will be a header-type ceramic coated turbo manifold, Mitsubishi 25g ball bearing turbo, intake system, 3" downpipe,intercooler, fuel computer, possibly some ECU fine tuning if needed, a much bigger fuel pump, fuel pressure regulator, and one or two additional injectors. The beauty of the supercharger coming off is that you now have ample room for the top-mount intercooler, which is more than double the thickness and cooling capacity as the stock unit.

Now, when will the power come on?? at 5k? Of course not, why would anyome want that in a street car? Any of you from the DSM car camp, Lancer evo3 or evo 4 owners or anyone who have a good knowledge of Mitsubishi ball bearing turbos knows that they are some of the best spooling turbos on the planet. The 25g used on the test car is capable of supporting 700hp and efficiently producing well over 30psi, yet its docile enough that it begins making boost at 2,500 rpm and full boost comes in at 3,500. Thats not quite as quick as a pulleyed MCS...but thats still enough driveability to satisfy most.

Theres not much that compares to the feeling and sound of the boost of a big turbo coming on at 2,500 RPM and relentlessly pulling at full force from 3,500 all the way to redline. The getrag transmission can reportedly handle 300hp...but getrag loves to under rate their gearboxes. The toyota supra is a perfect example of this. The getrag 6 speed in a supra has been proven to handle over 1,000 hp. I'm not saying the Mini's will, but time will tell us if the tranny will take 400hp or more. We are confident it will. Definitely add a phantom grip or quaife diff and some sticky tires, and hold on tight! I'll be keeping you posted!

 

I've seen a few v-tec Minis in MiniWorld magazine, those Minis must be crazy fast! I saw one for sale on ebay a few months ago. I wish I had the $ to buy it! I bet one of those would give the new MINI S a good run.

 

what about the Cooper.... Push the battery into the boot.... TWIN TURBO capacity... Sounds good to me...

I'd do it if I were made of money.... or had a huge sponsorship
