2.5" Piping Too Big? - mysterygirl - 08-29-2004
Well, jus drove my sisters car....damn it feels "peppy". She has the 2005 Focus 2.0L ZX3 SE.
Someone was telling me something about backpressure? Am I losing anything with my setup? or is the Duratec Engine just more "peppier"?
My setup is on my signature below

The Duratec has way more HP then a Zetec. With all your mods you are running, your probably getting basically the same HP output as your sister's stock 05. Your probably getting a bit more but her car is also newer so that could play a part in there. 2.5" exhaust, with all your running, that should be perfect.

2.5 is a little big... But meh... wont affect that much so I wouldnt worry about that.
The new focus's are just peppier.. just gotta live with that ... *shrug*

with the mods you have you should look into some cams next, something like a stage 2, also cam gear and dyno tune them, your car will feel incredibly different after that. :D

I thought only the 2.3l was the duratec? 2.0l was still a zetec?
2.5" Piping Too Big? - S2 - 08-30-2004
Actually the Duratec is available in a 2.0L (PZEV) and 2.3L....

Also, from all my experience with the focus, the best exhaust out there it seems is the BORLA SVT catback (works with both the SVT of course and the ZX3).... BORLA is a 2.5" setup. Your fine with a 2.5" exhaust. Perfect if you ask me....

also ask pat for his 2000 intake manifold and port your throttle body, matched with the cams and cam-gear you should see around 140 hp / 140 tq maybe ever 150 if your lucky and tune them well. ;)

The Duratec 20 (2.0L) and the Duratec 23 (2.3L) are indeed more peppy thats for sure!! The 2.3 started in the states to meet California standards as the PZEV (Partial Zero Emissions Vehicle) and was available in the 04's
2.5" Piping Too Big? - mysterygirl - 09-08-2004
now that just sucks!
all these mods I have now...are equivalent to a STOCK duratec?!! that hurts.
so cams next? turbocharger or supercharger?
2.5" Piping Too Big? - french_connection - 09-08-2004
well, I was saying cams and all, but if you can afford a little supercharger... :lol: slap a jackson on there and you'll be all over her. ;)
its the perfect mod to bolt on and forget about it, it need no maintenance at all and can be found used for a pretty descent price.
