Here's 2 that cost nothing;

Remove the air channel inside the air box(as per i200?).

Adjust the wee cog(spring tensioner) inside the air flow meter, the spring gets weeker with age and so the engine tends to run leaner, think the i200 had this adjusted when new....have still got the Manta Magic with the info in it but I'm sure someone can confirm the exact procedure quicker than it takes me to find the Manta Magic!

Some thing else, why not just check the ignition timing as well.

Put higher octane fuel in.

Cut out the collector box in the exhaust front pipe and weld in a straight pipe; all the performance systems do away with this box.

What about a K&N panel filter.

When was the fuel filter last replaced?

All of the above is easy and cheep .......or maybe you have some money to spend

All the best,

John.

Erm the spring gets weaker the flap opens more for the same air so the mixture get's richer not weaker? Pretty much like the mod - two thirds down this page

Put higher octane fuel in.

Not strictly true. If the car is correctly timed for the current octane putting in higher octane will make it slower!

What about a K&N panel filter.

There is an adapter from the AFM to filter on Peugeot 205 and others that adapts from AFM to round to allow cheap use of various cone filters instead of expensive kits and sorts the airbox issue too.

Additionally unless you are exceeding the CFM flow of the standard paper filter a performance one doesn't gove you any gains, that is a CLEAN paper filter may well not impact performance / get no gains from a performance filter compared to it, as it is designed to be adequate with 6K or 12K miles of dirt in it. A cheap mod the insurance company can't really moan about is to change you air filter more often.

I would chuck the airbox altogether and replace it with an after market adaptor and cone filter to bolt directly onto the air flow meter. I would fit 2.4 Frontera injectors and fuel rail(needs some minor mods)and use an adjustable fuel regulator. If you replace the petrol filter use a 86 Jag one, approx twice the capacity but has same manta 5/16 ends, for more oil filter capacity use a 3.0 litre monza one....

The cheap and well know way of doing that is in my post above, with Peugeot adapter

As i said "someone can confirm the exact procedure quicker than it takes me to find the Manta Magic!"

[mantaboy89]

are there any esay brake upgrades that are easy enough to carry out?

By far the easiest brake mod is the twin pots from a B series they will fit without any mounting modds just change your flexipipes for some goodridge B series pipes and away you go.
