easy mods?

The granny sedan needs a little upgrade lol... Stock 2.0. any thoughts on performance i was thinking bigger cams throttle body and maybe a chip. Still have egr and all that junk. I have a magnaflow high flow cat on it and a resonator delete but no difference. was thinking on a full rebuild but that's way out of the budget. mtx-75 trans any suggestions?

wideband air/fuel ratio gauge, nitrous, and tune. easiest and biggest bang for your buck power adder you can put on a focus

2.5" exhaust all the way back is the most satisfying thing I did to mine haha. :) Since you have your high flow cat, combine it with some headers (i have the FSWerks race headers, a little loud but they delete the cat so i'd stick with what u got), 2.5" flex pipe from c-f-m, i have a Flowmaster HP-2 Shorty Muffler, and had a shop make me the pipework all the way back

my car was a daily for a few years on the bottle. if the tune is good and you keep a close eye on it the nitrous wont hurt anything. of course that is assuming you dont go over a 100-125 shot on a regular basis.

and its only illegal if you get caught. remote bottle opener and a quick line disconnect in the cab of the car and youre good. they cant do a thing if the kit isnt hooked up when they walk up to the car.

svt header,svt air box/snorkel, orp tube or keep your hi-flow cat, 2.5" flex pipe ,2.5" fswerks stealth exhaust and tune. This from my experience is one of the best combinations.

WARNING!!!! INCOMING BOOK ALERT!

maybe i am a bit of a bad influence but its the truth nonetheless. it is also against the law to run an off road pipe, or delete the EGR but people do this quite often and never bat an eyelash. if you want to keep the easy daily driver function of the car AND make easy cheap power when you want it then nitrous is the simplest way to do it. the car will drive and function like stock for daily driving and if you decide you want to hit it for whatever reason it is ready to go within a few seconds.

other bolt on mods like header, exhaust, intake are fine but truth be told you wont feel any noticeable difference. maybe if you do a svt header conversion you might feel a little bit. the only way you will notice any real difference in performance will be with some form of forced induction like a supercharger, nitrous, or a turbo kit.

superchargers are expensive and a pain in the ass to put on in my experience with my jackson racing supercharger that i had and the power gain is very low for the effort and money. you might get 180whp on a JRSC and the absolute most you will get from ANY supercharger on a standard zetec platform is around 220whp.

turbo kits are the only way to go if you want immediate consistent power on tap but once again they are expensive. i would say its less of a pain to install a turbo than a supercharger personally. it takes a little longer because there are more small things to put on but is overall less frustrating. but if you go this route you will loose some driveability with the car. for example you will have to run a more aggressive clutch which will be harder to operate on the street and it will not last for nearly as many miles.

with the nitrous kit you can leave the car otherwise STOCK so it will drive exactly the same with the kit as it does without it until you turn it on. you can still run an oem clutch which will hold quite a bit of juice before it pushes it to the point of slipping unless its already worn out. i also found out from personal experience that an OEM replacement clutch from exedy will hold a 125shot with full bolt ons with no problem. i ran that clutch for 60k miles or more and after it came out of the car for a clutch that will hold 400ft/lbs/tq it still looks like it has lots of good usable life left in it.

if you disagree with me thats fine but the guy wouldnt be here asking questions if he didnt want peoples opinions so i felt compelled to give mine.

final note: you never mentioned if your car is automatic or manual. it it is manual everything i said up until now applies. if it is automatic i would take it easy on the spirited driving because they dont hold up so well to abuse unless the have performance torque converters and other internal upgrades. from what i understand a stock automatic trans is good for around 160-180hp with a good tune. and for that matter a simple tune with an automatic trans and you WILL notice a significant difference in performance.
