Zetec mods.. what next?

Nos ?

What mods does your insurance company allow? DIY gass flowed head, scrapyard turbo or supercharger conversion?

There is no next: everything costs money and even the sun doesn't rise for free.

The only thing that cost but thinking is loosing weight on the car. 20-

30 kg is possible without any hassle. 200 kg is possible too but it won't be easy nor cheap.

I like flywheel shaving as it gives the car far crisper accelleration in low gears. On modern engines taking 2-3 kg of it lets the engine idle as sweet as before. You want extra torque? And for free? 100% reliable?

You want the moon, my dear fellow... but maybe you could take away the cat and replace it by a straight pipe. It frees up around 5 Hp, fuel consumption drops and you loose 3-4 kg. Make it so that for MOT you can easily replace the cat.

The three items (weight, flywheel and cat) will modify the behavior of your car but do not expect a transformation to a rocket. The above works and is condemned by the one who proposes them.

Oy yes: did you weight your new exhaust / compare it to the original?

Rip the insides out of it, like Tom says. You'll get sick of the noise and it'll be a pain in the arse to get all the trim back in if you ever want to sell it. A good trick is to buy some dry ice, put it all on the floor and the underseal will just chip off.

Take a couple of mm off the head, use Super unleaded to stop it detonating, thats almost free to do and will give you 5 to 10 percent more go at all rpms. Careful head gas flow (mainly a good careful valve seat cutting job, also gives a bit more. All DIY stuff and cheap. After that go here

Or buy a better rear drive bigger engined car.
