Default Performance Mods To 1991 Ford EA 3.9L Multipoint Injection Car

Hello all,
i have no idea on motors. i only understand electronics.
So far i have done nothing to my engine.
To make matters worse (maybe) the car in on LPG.
I want to get some more straight line power from the car.
But i do not want to reduce weight...ie the subs in the boot

Car has a 2.5" exhaust system from the cat back
Car has brand new radiator...i think a better than stock on but nothing too special and has just had head gasget done

What mods can i do ranging from cheapest to dearest to get some more power out of the motor...keep in mind what mods i do now i need to work in future if say turbo is added or whatever.

I have read putting on a Xh snorkle and K & N filter into stock air box helps
I have also read about putting on some extractors and high flow cat converter

are both these true
if not please make a list of mods i should do
thanks all
BRADMAN

ensure the ignition system is in good nic.
plugs/leads/coil

extractors help, cam also is a cheap mod if you can install yourself.
a good tune up (advance timing) and service can help a tad.

often the small things make a nice difference.

Convert it to manual if not already done so. A shorter set of diff gears will also help.

i have found a few different extractors on ebay
do you need any specific type given that my car is on LPG?
how do i know the difference between a stock set of extractors and some "racing" extractors?
where can i buy a high flow cat converter?
Thanks all

A stock set of headers will look like a log :P, any aftermarket extractors will have elongated primaries. It's not hard to tell the difference...
