I agree, no "extra" power no, but it certainly will bring any bhp figures back closer to what it had the day it left the factory.
It's not about saving money fast though is it. My plan is i'm saving for a black Ep3 Type R. I could save the money for that in less time than two years, if I devoted more money to saving, however the insurance on a 2ltr v-tec monster is going to be about 2.5 / 3k at my age. If I wait until i'm 21, or even 25, it'll be much less, especially with more NCB.
So saving a hundred or two each month and spending a couple hundred in total on my clio / his clio really isn't going to waste. SOmeone mentioned previously that he upgraded bushes/suspension by 35mm and good tyres, and it handled like a demon. Then said that they regretted spending the money and should have gone on holiday. Really? Should you be on a Clio owners site with the general subject being modifying with a mindset like that?
The main thing is the lad is enjoying it very much and is very excited about all these mods, and is asking for any other/better ideas from more experienced people. He's not a troll. It's a learning experience. I may well be back on this forum in years to come pleading with 18 year olds to save their money. For now, let's get back on topic.
Lower it with your coilovers 30-50mm
Get good Tyres
Good and regular service
Upgrade the anti roll bushes
I'd stay clear of the remap.. As mentioned a lot of money for less than 10hp. The DCI route looks like the best idea out there as said above! Very eco, cheap tax, win win!
