Just wondering if anyone offers a stroker kit or if there is enough meat in the block to do an over bore?? i know new pistons (bigger if bored and with a diffrent pin hight if stroked) would be needed.

thanks Chris.

Overbore + stroker = 2.0L, but its not available yet. Its coming out some time this year from Revolution MINI Works in California. Thats just about all thats publicly known at the moment.

Woah. Implications....? thin wall of engine? strain on drive train ?

Hmmm....

Cheers,

New liners and more stroke luckly we'll be able to offer them on an exchage basis as we do have quite a few cores lying around.

I saw some interesting pictures of it. Will be interesting to see how it compares with the GTT/Fireballed! Turbo kits, or the MiniManiaUK Opcon kits.

its a shame but I think turbo is out of most peoples reach at say £8000+ vat for the fireballed kit but on a more realistic £5000ish tuning budget it looks like it will be up to minimania in the UK for a opcon supercharger up grade or revelution mini in USA is a rotrex supercharger up grade and it will hopefully still net the big 300bhp... happy days..

I'm still not convinced about turbo conversions. I want more power, but I have always liked Superchargers more. I just dont like any lag. Price is an issue too. Its probably a bigger issue than the power.

I imagine a stroker engine + rotrex kit might end up similar power to a turbo, but I would think it may be similar cost too due to the amount of work that needs doing. Untested design too in this application. How well will a 2.0L engine cope in the long term? Even if its cheaper you may have to pay the difference between the stroker engine cost and full turbo kit in more regular engine rebuilds and maintenance.

Stroker kits are proven technology in the Skyline community though. Rotrex kits certainly develop some nice power on Civic Type R's and Nissan 350Z's.

Its an interesting time at the moment for MINI tuning, and I think all these different developments can result in bigger and better things as the competition between tuners hots up.

Now if only I could fit the 2.4L SRT-4 engine to the MINI

Hi Alex,......wait till weve taken you out in our turbo, you wont want anything else once you have. More cc or bigger S/C or Twincharge on an MCS will never outperform a 'turbo only' set up. I said this 3 years ago about the MCS and I'll stand by that.

Its a good thing to have choices,and MINI owners are getting a good selection! -Turbo,Opcon,Twincharge,Nitrous,Stroker, all different means to the same end.
No doubt there will be more choices in the future,and indeed combinations of the above,even the unexpected ( the diesel may still have its day),
whichever choice ,300 bhp or large torque cars,are going to cost,if not in conversion prices,then in running costs,tyres,clutches,mounts,insurance.
300 is a LOT of power in a small engined light car ,you could destroy a set of tyres in an hour with ease!! producing more power is possible,but beyond 300 you get diminishing returns,and the car becomes a specialist car ,track use ,drag use,rally car etc and far more prone to premature failures.
250bhp per Ton or nearly 190bhp/litre is a lot of car, not bettered easily, and only a small percentage of owners would want it. As the MINI gets cheaper these conversions will get more popular,a £3000 cooper s with a conversion is a great bang for buck,and next year we will see £3000 cooper s cars!! probably with broken chargers and worn clutches.
Still lots of good things to come for MINI owners much like the original mini -once the warranty expires and BMW dont want to know

[Bhozar]

Funny you say about engine mounts and clutches; my clutch is on its way out and I had to uprate my engine mounts with Proflex bushings as the engine was rocking too much.

What ever option I go for in the end I still want it to be a daily driver for another year or two. After that it just needs to be road legal and useable on the roads at the weekend.

The Fireballed! lot in California have a couple of mad BHP turbo only cars on the road used as daily drivers. I think they are all 400bhp+, and they still manage to use them daily. Not sure they would actually say, "Love the car, but no way can you use it in traffic or every day to commute to work."

So who can make me a stroker, opcon, turbo, twincharge kit?

[chuntington101]

Bhozar, well a stroked, opcon supercharged twinchared car would make sence. lol

you want the stroker to reduce the specific loads on the engine. bigger engines make the smae power with less stress. also it would make it easier to drive everyday!

then you just have to have a bigger suoercharger to take adavantage of the bigger engine. if you dont then you are just going to run the stock supercharger to fast and increae inlet temps! and we all know thats bad!

then to stop the stroker being slugish at the topend you have to have to turbo on there to!

thats my thinking anyway! lol

Chris.

PS. thanks for all that guys. i did a search but couldn't find anything. has anyone got any links or anything to boreing/stroking the mini engine?????

[Bhozar]

I think there are only a couple of posts on MINI2 about stroker engines, and a couple more on NAM about it. At the moment info is scarce as the engine hasnt been released or seen by much fo the public so far. Only person I know doing a stroker kit is Jan from Revoltion Mini Works. He is the same guy doing the Rotrex kit.

[Revolution Mini Works]

I can tell you this..............

the strokers are alive and well........

I have one in the drag car that has put amazing numbers down on less psi than any Mini I have ever seen. I am making more torque than the other turbo Mini's hp numbers!

I also have one in a street/track car now for testing. It won't be long til I release it.

I have another stroker that I am making that will really make your head spin.

[Paul Webster]

Sounds good Jan espically for us heavyweights weighed in at 2572lb the other day but I'm legal to 8.50 now.

I undestand why you want some custom axles now, any date on these yet?

no, I haven't heard for sure when they will be done, you know how the car community is

they promise you a date and then you watch it pass without a whimper

Yup its sad, Liberty mucked my mate around for 5 months, but they are always going to look after there main income stream first (pro stock etc) he ended up with a 5spd G force box in the end

you are right about that, not many people are interested in doing 1 offs when they can deal with the Honda community! It's a fact of our cars and being pioneers in making hp

What is worse is I develop something only for the rest of the community to try and steal it away.

Jan, you sound as paranoid as I am! Its not that I think they're talking about me, its that a know they are talking about me!

Well, when my manufacturers call me and say so and so called and wants to have it made for them with my proprietary piece.... yeah that's a problem

Youre lucky to have a manufacturer that tells you!
