To build or not to build?

[AntonUK]

Hi Fellow Petrol Heads,
I currently run a highly modified Mini Clubman Estate ((some old photos here)). Its runs a 1380cc, race head & Cam, megajolt, 45DCOE, straight cut gears etc etc... but tbo its not quick enough. Having always wanted a Westfield, Caterham, Lotus 7 kinda car, it has led me to this site... I have been reading your forum for a while now.

What I really want is a silly quick car, 250bhp+ that's fairly cheap to keep and has the potential to tinker with it some weekends then drive it to a track the next and have some fun with it

What I would really like to know is if the plans I have are viable. I'm planning a car based on a locost/haynes chassis, Fuel injected 1.8 zetec lump with a single turbo hanging of the back of it. Having built the mini, I have the tools and capability, there is going to be a learning curve with the fuel injection and but that's half the fun.

Are things like brakes, diffs, clutches available to handle this kinda thing? or will it be custom stuff?

Comments / Opinions most welcome?
