Drivetrain 2003 Mini Cooper Engine Swap-KLZE v6
2003 Mini Cooper Engine Swap-KLZE v6
I have a 2003 Mini Cooper that is going under a full overhaul. I've ordered Carbon fiber Doors, Seats, Hatch, and Hood to reduce weight. I'm still shopping for coilovers and sways bars. LSD & Short Shifter, full sha-bang And I've decided on going with Team Dynamic Ultralight race wheels. As I look into enhancing the tuning of my mini I cant help but notice that the original engines tend to lack some power. Im not knocking cooper s or john cooper works but Its very rare to see a mini with 300+lbs of foot torque. HP is great but it isn't what really gets you going. In the past I have built MX-3's with KLZE's but I was wondering what experiences people have had with Mini Cooper Engine Swaps. What are any problems you have experienced? And if you find that a KLZE isn't a prime choice then what is your suggestion? Like i said, I just tend to favor the Japanese block due to familiarity and low expense. So what are your thoughts or suggestions?
The 1st Gen Mini engine is a Chrysler engine in it's base form......How MINI is that? The motor isn't what makes a Mini a Mini, no?
That being said, with all the lightweight parts you're swapping in, I think you'll find you don't need 300 ft/lbs of torque to really scoot. Think Lotus Elise. Unless, as stated by BensMini - you're wanting a drag car.....

An MX-6 engine in a MINI. Unless you plan on a rear engine conversion and have unlimited funds it's a pipe dream. There has been a Vtech turbo swap done in the UK with far from stellar results.




No links that I could ever find and as far as which Honda engine was swapped I have no clue. Here's a useless dyno vid.

It's a Mazda motor, made for front wheel drive cars.
Wouldn't it be a big project integrating the Mazda ECU and the Mini's computer? There's a lot of things in the Mini that are computer controlled, that are peripheral to the Mini's ECU.

Well, I would! I'd want the transplant to be seamless, to look, and work as though the bigger engine had always been there, including electronic peripherals. It is so much more elegant that way.

Is that the little 1.5L one they had back in the early 90's? Or is that the same as the Ford Duratec that was in the Probe?
KL-ZE
I would rather do a 1.8bpt smaller block and tons more aftermarket. Almost the same hp output as well. The BPD is the cool version of that block. It outputs more than the kl-ze and the internals are better in stock form. For the 199hp the kl-ze puts out I would rather save the money in aftermarket for the BPD block.
- 1997 Mazda Capella Wagon
- 1993+ Mazda MX-6 Jspec
- 1993+ Mazda MS-8 (Japan)
- 1993+ Mazda Eunos 600/800 (Japan)

Ok. To clear up some misunderstandings. The KLZE is a 2.5l v6 fwd Mazda engine. Its a compact v6 that can fit in mx3s and 626 so i KNOW it can fit in a mini cooper. Its natural aspirated output is 200-240hp depending on whether one attains a old mx6 or jdm import with 240. It´s easy to tune and low in cost. I know that its accepted to swap first gens but for all those second gen lovers. Losen up, i know you love your stock minis and for all i care you can keep em stock. Where I live, everybody has a porsche or bmw. I got a 2003 mini for 10k in mint condition. I love the handling in my mini but the power is very dissappointing. So all im asking is what engine possiblities should i consider. ECU and engine mounts will be a problem i will solve but right now i want the best engine available and i want to know my options in order to get started prepping it.
As for klze's theres a been cases of 800-100hp and Im not looking to push it that far. I would be content with 300 or so. Low boost and lightweight is my plan. I can raise the power if need be but I still want a DD.

I'm really glad to see you understand the reality of not being able to get 300 lbs of torque out of the MINI motor.
As for swaybars we have the best Hsport bars in Stock.
Then for LSD's, wait till you figure out your powerplant, but OS Giken that we sell makes great LSD's for more than just MINI's. Sounds like a Crazy fun project.
