Hi thinking about selling/swapping my seat leon cupra and going the rs route (stupid I suppose after spending 4k on modding it) , problem is I love the S1 but want something that can be quicker than my leon cupra which is currently running 229bhp and 230 Torque?

Do you think it would be possible to get a decent s1 and this sort of power for £5k that could be quicker than my cupra and also be reliable?

Any help on this would be appreciated.
