Still testing different exhaust header flange openings with the new port shape. I didn't care so much for the restrictive round header opening matched to the oval exhaust port. Don't need a reversion step that mismatched.

Right now I'm playing around with the stock engine and ECU and pushing it as far as I can.

I am also working on the spare bottom end as well.

I should probably start a build thread somewhere instead of posting in here.

10yrs+ and still they dream of a 200hp zetec. If it wasnt a small truck motor at heart people wouldnt have to ask bc the info would be plentiful on how. Tell folks u have 200bhp and have something fun to drive. That or get a hair dryer. Akin to comparing us with hondas in the 1/4. More parts more development more numbers but... less weight.

To be completely honest! The head will probably never see a flow bench and the wheels will never touch a dynos rollers. I'm good with that, as long as the mods that I do make it funner to drive in the end. That and they don't cost me $10K like my ongoing N/A Honda build!

i'm pretty sure Its all about the $$$ why spend the money for N/A when you could blow on a turbo for double the ##'s. I'm got my svt cheap only to blow my headgasket in the driveway, now i'm thinking that massive head is looking like a good idea.

It is much more than the $$$ in some cases. I consider it to be more of a challenge to make power N/A! I've done a few 350-450whp 1.8L and 500whp 2.4L boosted Honda builds. Sure it's fun beating the all mighty Mustang and Camaro down the track. But to be honest, boost builds are pretty easy! And to do them properly they can be just as expensive as an N/A build hp/$.

at this point in time, I think its pretty cool for those that break that 200whp because it seems almost taboo.

Because if I boost my car with good parts I'm over the 500whp mark pretty easily. but then I'll need stock in a tire company.


~200 and 2,300# makes for a very fun Focus.

You can do 250 to 300 with a turbo very easily. 200 all motor means twisting a motor that was never meant to twist like that. Put the SVT head on put the Ford manifold on or combination of SVT Cosworth whatever manifold you want to put on it put big cams in it doesn't matter. To get that power you have to turn rpm's at your motor was never meant to turn or will do safely on a repeated basis. It'll likely be flat on torque and not in keeping with what the focus is. Then you end up with a portly Honda with no VTEC on top to pull you back up. that's what you have. Off the soapbox.

What do you mean by twist? I'm assuming you mean engine speed or RPM. Were the ZETEC pistons or rods specifically made to take boost? If I wanted Boost I'd buy an STi.

So in your eyes what makes them not like 7000rpm or twisting?

What would happen if you were to lighten the pistons, increase displacement and compression, strengthen your rod bolts, and change the bearing clearances accordingly?

Don't ask why would I bother? I know you can build a cheap boosted car that will run 300whp all day. I'm not interested. This is The N/A Zetec Performance Thread... not the lets have all the snail lovers bash N/A builds thread!


Anywho,
Here are some pictures to go along with my MAF instal thread above. No this is not a Focus, it is a ZETEC though.

6" - 3" velocity stack,


6" K&N filter over the stack,


Pro-M housing and GMS MAF,

I prefer na actually. But in all these years of the zetec what it can do and not do is pretty well known and past development. Its the head primarily. Sadly to make that high hp level you need to a crazy high rpm race gas grenade. And prolly gotta eat a good amt of the low and midrange tq this motor does well. A pt where u got to put focus no pun on ur motor's strengths instead of dreaming of a # on a graph.

Again to summarize, if 200hp was feasible u would see far more info on how to do it. Seen many builds over yrs with cool manifolds, big lumpy cams, more headwork than a nympho girlfriend, bored 20 over, race gas and they all end up 170-180.

Pick your poison. I toy with turbo idea on a zetec, but the duratec donor will be here next wkend.

Keep pushing
