Exhaust, then full intake (cai/sri, throttle body, possibly early 00 intake mani)
Tune
Cams w/gears
Head work
Then possibly race intake manifold and possibly 4.10 gears at that point.

The list goes on and on, just depends where you wanna stop.

Okay i have a 2000 Focus SE and i just put a Flowmaster catback exhaust on the other day. At first it was kinda quiet but then i let the gas run out and put 93 grade gasoline in. It sounds a whole lot better but the downside is when i rev; the RPM's drop down and theres low popping or grumbling sound like a Honda with a 3.5 inch exhaust smh. My friend told me that i may be running rich; because i do have a huge problem with gas and i need to replace my plugs because the maintenance of this car wasn't done entirely before i bought it earlier this year. What by this what do you think my prob is?

what else could i do to boost performance after this. I also installed a Steeda CAI.
im trying to get to at least 250hp by this upcoming summer.

Sorry for the bump but I've been doing a lot of research myself as I'm considering buying a ZX3 Zetec and doing an all motor build.

What strikes me as intriguing is when you compare the Zetec to say stock rice B series, there's a 20 horsepower gap between the two despite the Zetec having a slightly higher capacity. On the other hand, the Zetec is much torquier. Also interesting is where the two engines are making these numbers. The Zetec peaks at around 5800 revs whilst the B16 is making peak power up at 7600. Other than that, the two engines are similar.

After reading around on the forums, I just wonder why the general consensus is that 200hp is the max output for a Zetec? Guys are pushing 240-250 with N/A B16's, what's holding the Zetec back? Forget about the money nor time needed to do so, I want to know if one of these engines can push 235 all motor.

I'm going to be going to ODU this fall to study Motorsports Engineering Technology and when I get out (or hell, if I had $8000 bucks to spend), I want to build an all motor Zetec pushing over 200 (235 ideally). It's crazy as hell and although I could easily get that with forced induction, you have to respect a 4cyl making numbers like that N/A. I'd also like to take a S-Type and do a possible AWD conversion but that's a whole nother thread altogether and I won't go into that.

So 235 is what I believe to be the ideal number. Anymore than that I feel is overkill for a front wheel drive car because I want something more track oriented and torque steer would be a big issue.

The question lies in how to get there. Obviously, you'd have to go the whole nine yards. Pistons, rods, port, head, camshaft, there'd be some serious engine work to be done. Compression ratio through the roof. But is it possible? I think it is. What I'd like to know is how the Zetec would perform if one was to fully build one out and run it at 8000rpm. With a higher compression ration, better breathing, crazy cams and some ecu work, could we be pushing power past 6700rpm? That's what I wanna know. It looks to me that there's a lot that can be made with the engine IF one had the dedication to go that route. I also would be interested in seeing a Zetec put on a airflow bench. That would tell us what could truly be made

The head on the zetec does not flow now where near like the B-series motors that's why we can't make the power they make. Or well we can get close but by then your using race gas. Also you can take the zetec to 8k rpm but we are known to have oil pump failures even with the billet oil pump gears they can still break.

Yes it can be done I did it back in the early 2000`s for a track car , almost 14to 1 compression , custom cams , HUGH head from a casting you cant find any more , custom intake , SVT header etc , question is ... why do it needs 12.00 a gallon fuel , will eat it self in about 5000 miles , to much cost for the return but it has been done , did 230ish

Well, it's something that I've thought of for awhile and to pull something like that off I feel would be a pretty large feat. I mean, even getting to 210 would be more than enough and if you did decide to go forced induction, you would have a great base to work with. But a 230 horse Zetec? That's some major respect points. Personally, I'm an all motor guy myself so that's why I would go that route and it's something I've always dreamed of doing. Noone would expect a N/A Zetec to make that power and that's what is so appealing to me. Heck, I'd be satisfied with 210 or 200 like I said

I've looked about and there is a English company called CNC heads that sell custom fabricated cylinder heads. I wonder what the gains are from those.

I should be able to confirm weather or not better than 200 is possible in the next few months.
Also once the summer fuel comes back I need to run a before dyno. My bottom end will consist of Eagle rods and Wossner 12:1 pistons. With my shaved head this should put my static compression ratio near the 14:1 point, I'll have to clay/measure to make sure though. last dyno was half-assed tuned and on a different intake manifold. I now have the Ford Racing Intake Manifold and a bit more tuning into it as well as more RPM.
Even still I'm easily 200 motor HP as it sits.
My goal from the get go has been 200 wheel HP, at reasonable cost.

I see 235 being easily attainable, with enough RPM. Which happens to be what you're overlooking when comparing the zetec to Honda's. I'm sure once you get a bit of schooling under your belt you'll understand the interactions better and see were you're errors are.

The kicker on any high compression build is the quality of the fuel. Pump 93 isn't going to cut it if you want good real power.
... but I'm not using 'gasoline' so I'm not really scared of deto.
