how can i make my 1.6 16 petrol engine leon faster??

Well if you want to make your car go slower you sure are going about it the right way. I would imagine that even with a pipe and induction mods you're car will still be slower than it was when it was stock, (after all that weight that you've added). Basically on a normally aspirated engine you're only going to make your engine make less power by adding a free-flowing induction and exhaust unless you sort out the fuelling too as you will have just made it run leaner, (and standard engines nearly always run on the lean side anyway to get through emissions tests etc). Real question is can the stock ECU deal with the required fuelling changes it'll have to make after the induction changes will have changed everything?

Also there is the whole issue of the tuning of the induction. In a normally aspirated engine the length of the inlets and induction piping can have a very significant effect on power output. Generally speaking manufacturers are pretty good at getting it right and usually making mods to the inlet system will only result in a messed up power curve. If you gain more than 5% through the midrange or top end on a modern NA engine with just decatted pipe and induction kit I'd be amazed, and that's assuming you sort out the fuelling.

tell the truth the bodykit is fibre glass, so it is much lighter than the stock bumpers anyway. The alloys probably add more weight to the car though

you'd prob be better going for a re map if you want to see a noticeable difference in power. an air filter won't increase the power by much, however it will probably make the car more responsive.

i personally would upgrade the suspension or brakes 1st. you'll upgrade the handling significantly and be able to go through the twisty sections quicker, that's where you'll have most fun. don't get me wrong you'll still get left behind at traffic lights but that'd still happen with an air filter / exhaust fitted

sorry just realised that the above link is sensored.
the ****** is for the other .net "seat forum"

it might give you some ideas

I would save the cash for suspension and brake upgrades as said, your going to spend a lot of cash for say 10bhp? Hardly worth it, it will make naff all perfromance difference.
I know its very frustraiting having to drive lower power cars due to insurance and the like but we've all done it.
Difficult as it may be you could even save the cash for a cupra in the future?
Just my 2pennth..
