Hi there, first i thought it was impossible with what you are looking for. So i just looking around in my garage... and i found a MG TF160 '03.
Changed oil and added improved body rigidity. Stage 2 Weight reduction, carbon hood and added ballast weight 42kg. sorry its 32kg.
I then put in Stage 2 engine tuning, sports computer, racing exhaust and the manifold, catalytic converter and intake tuning. All that adds up to 260hp with 449pp at this stage power limiter is at 100%
I think there is a lot more cars that can be a potential to you what you need.
