Well I think I'm at a point now where I can just about justify a project thread. I never ever anticipated to get into what I have, but hey ho :)

I bought my JCW R53 not long ago (having had a MCS before) as a promotional car for my photography business. However, it became quickly apparent that I wanted to put in on track - and to do it properly.

My last car was a 2006 Subaru Imprezza WRX 2.5 which I bought and spent quite a lot of cash modifying - but not doing it properly as it was a daily hag too.

But enough about that!

As it stands at the latest update:

Mad4Mini in Leeds are my local Mini specialist who have stripped the car for me, and together (with the assistance of Jan & RMW - who has been superb! and Jeff at Howerton Engineering for the Meth solution) we are hoping to complete the build in the next 2 months :)

Car with boxes full of new gear!

GRS motorsport intercooler was put on, but it soon became apparent it wasn't going to quench my needs!

Rear bumper off, checking routing of braided hosing for meth from the battery area

Initial strip - CD changer coming out!

Brand new callipers

Black mounts

Lovely new seats!

So at present, the car is stripped as much as possible, we're awaiting suspension, brakes and wheels to get it rolling again.

As soon as we get the engine components, we'll get it bored out to 1.7L and get the engine fully forged and the stroker built. The head will be a couple of weeks behind that, along with the Rotrex.

So at the moment - we're at a standstill other than body work / painting and interior work / cabling :)

What a list.

I just cant understand why people would spend money (brand new parts) which are fucking expensive, on a mini..

With that dough you could have such a nice stock motor..

I've had nice motors - and I've had expensive motors :) But that's not the point is it ... ?

For what I paid for the car and the mod list, pound for pound the fun factor will be epic!
It's going to be used in hill climbs, track days and hopefully, in 2013 - time attack!

@Jack - yep, I was introducing Abby today to Meth and what we were doing with the build. She's really interested!

Mad4Mini aren't building the engine, we're taking that to a company in Bradford to be assembled and tested :)

I'm meeting with Steve this week to discuss the rear cage and harness bar that Nige (brownpants) has been talking about.
I'm really just waiting for parts / manufacturing now. In the mean time I'm working on the electronics in the car, and I have decided to fabricate some slider mounts for the drivers side seat, get the battery sorted out and start to build a custom electronics panel for the meth / switchable maps etc :)
