Hi everyone,

I bought a Grey 2009 MCS 3 months ago. Initially as a car for my partner to drive. The car had 27k on the clock with one owner from new with FSH. Was in quite good condition, everything working as should, one slight carpark ding on the drivers door was all I could fault it on.

After owning for a month it developed a slight death rattle when cold. Im up near Aberdeen, with no mini specialists near me, so I spoke to Lohen for advice. After removing the rocker cover I discovered the timing chain was slightly stretched. Although the car had now only covered 29k from new and wasn't too bad of a rattle I thought I would leave it to see how it develops. A week later it hadn't changed but for peace of mind I booked in with Lohen for a timing chain replacement, de-coke service and their performance pack 2 consisting of;

Lohen Performance Pack 2,

ITG Panel Filter
NGK Uprated Plugs
Forge Front Mount Intercooler
Akrapovic 100cell Sports Cat
Manic Motorsport Stage 2 Tune (Maps, A,B,C)

I also purchased the optional Manic SPS switch so I could change between maps via the OBD port

On the DYNO my car made,

247.4HP @ 5679rpm
394.6NM @ 3021rpm

The package completely transformed the cars performance and Lohen did a great job working late on a Friday night to complete the job as I had a 6 hour drive home to complete after.

About a week after returning my clutch starting slipping in Map C, I then spoke to Lohen about a clutch, flywheel and much needed LSD package to get the power to the road. I ran the car in Map A which helped with the clutch until I could figure out when I could get time off work to do the 6 hour drive down to Lohen again.

A couple of weeks later ( roughly 3 weeks ago ) whilst driving home from work the car starting misfiring, I was doing around 50mph in 6th gear at the time just cruising.

I let 2 mechanics at my work investigate and I spoke with Lohen. Turns out it was a failed piston ring in cylinder 1. :(

Currently the complete front end is off the car with the engine and transmission removed and block stripped down.

I seriously caught the mini bug after my performance pack from Lohen. Im planning on doing a fully forged rebuild. While the engine has been out my OCD has kicked in. I have removed the subframe and completely stripped and refurbished with new components. As im aiming for a fast road / track car i want to basically do a nut and bolt job on the car upgrading anything i can, and anything not worth doing im completely stripping and refurbishing.

I have took photos from each step of removing the engine and transmission for anyone needing advice I would be happy to help and should have photos to aid.

Going forward I have done a lot of research online and spoke to numerous machine shops and mini specialists both in the UK and USA. I still don't have a full plan of what I am doing to gain power ( Engine, Turbo, Transmission and all other supporting changes needed to complete this ) Any help from people with 300hp+ N14's would be greatly appreciated. I have been very busy purchasing suspension, brakes, interior and exterior upgrades at the moment as I cant buy anything / am reluctant to buy anything engine wise until I have a full plan of what to do and who is going to do the work.

The Plan; (* = already purchased ) I have nothing installed on the car just now, ( parcels coming everyday the last two weeks lol ) Everything I've purchased is brand new as I am going to put a lot of money into this build i don't want any second hand parts breaking on me early

SUSPENSION

ALTA PSRS rear wishbone bushes *
ALTA Front and Rear adjustable drop links *
MOOG Track tie rods *
MOOG Lower wishbone arms & ball joints *

KW clubsport coilovers / XYZ racing spec coilovers
KW anti-roll bars with powerflex purple series bushes / Eibach anti-roll bars with powerflex purple series bushes
Eibach adjustable rear control arms / Forge adjustable rear control arms

BRAKES

REFURBISHED rear callipers *
Brembo Xtra rear discs *
Mintex M1144 rear pads *
HEL front and rear brake lines *

TAROX 10 POT big brake kit / AP 2 piece big brake kit / Brembo 2 piece big brake kit

EXTERIOR

Carbon fibre wing mirrors *
Carbon fibre door handles *
Carbon fibre beltline kit *
Carbon fibre boot handle *
Carbon fibre bonnet scoop *
Carbon fibre front light surrounds *
Carbon fibre scuttle panels *
Hydro dipped carbon fibre wiper blades *
Hydro dipped carbon fibre rear light surrounds *
ALTA short radio Ariel *

JCW aero kit
Carbon fibre / hydro dipped front grille surround
Carbon fibre / fog light surrounds
New headlights
New rear lights
GP2 rear diffuser
GP2 engine undertray
AG carbon fibre rear spoiler wing
some sort of front splitter

INTERIOR

SPARCO ADV - LF seats x 2 *
SPARCO RAILS *

Custom weld in cage
Harnesses
Gauges
etc (not put much thought into this as unsure to do with build if I will require fuel cell, Meth tank, wiring etc so thought I would do this last )

TRANSMISSION

Unsure, depending on recommendations to handle the power

ENGINE & TURBO

Really unsure ha.

Was thinking of Supertech head and carillo / supertech bottom end

Possibly gtx2867r or gt2860rs

Will post any new parts I buy and will update on the build as I get more of a plan together. I really want to get the engine away and and get work started on it. Communication and waiting on replies has been my hold up to date.

Here's another good reference thread --- https://www.minitorque.com/forum/f272/thepenls-r56-25947/ --- takes awhile to get thru it, but lotsa good info. My own monster is strictly for power, with minimal handling mods --- current info is on another forum --- https://www.northamericanmotoring.com/forums/mini-mini-builds/334228-update-to-obw-s-build-dec-2018-a.html --- my MT build thread isn't current.

Over 300WHP will need a Cylinder Support System of some sort --- there's virtually nothing around the N14 cylinders. As for turbo selection, take a look at Garrett's new G25-550 & 660 models. My GTX2860R appears to be maxed out, and their 2867 series isn't much better.

Have fun with your build and keep us posted ---

Thanks for the links and the advice. I forgot to add in my spec about sleeves, but ye will most definitely be installing Darton mid sleeves.

I'd have thought Lohen would have cautioned you over the vulnerability of the N14 before going ahead on even a low mileage car, it's not like there is any shortage of failure stories which they must know very well, regardless though it is nice to see you're looking ahead, and keeping the car going with what looks like a good plan...

Thanks mate.

Ye they warned me, so did my mechanics, think with the car having that low mileage would definitely not help. One careful lady owner before me, so the car has probably never been warmed up etc then with me increasing power and pushing it a little has not helped with the its previous life ha

Sorry to hear about your troubles. Hope you manage to get everything fixed up and your car back on the road (and track) soon.
