yea deff need some major tuning my car is a 2000 zx3 just has svt header and full 2.5 in exhaust with ported 2000 intake mani - my car has 115,000 miles on it and i made 132whp and 130wtq thanks to "mcnews automotive".... then again idk who ported your head but that alone can mess up a motor / your power numbers... a ported 2000 intake manifold flows well till 165 whp btw.

you also should set the revlimiter up to 7000 or 7200 and dont go past that unless you have upgraded oil pump just for safety
 
you can go to 7400 and a bit over safely. the SVT and zetec use the same pump and the svt has a 7400 rpm rev limit.
 
7400 is fine. people beat the snot out of the svt motor as the rev limiter cuts out at 7400 and i've VERY rarely ever seen anyone blow an svt motor. at least not to high revving.
 
correct me if im wrong but... he is not driving an svt... svt's do hold up very well. he has a reg zetec .... svt = forged internals+piston oil squirters ... reg zetec doesnt... im not saying u cant spin it to 7400... u can... if u choose to might wana play it safe and put an oil pressure guage in the car.

not being smart or anything im just saying... mcnews automotive (who is my tuner) is widely known im great friends with Bobby Mcnew and Ray Mcnew they are 5 miles up the road from me. they have tuned thousands of focuses (they are one of the best in the business) both svt and reg zetec. i've heard many many stories of peoples focuses from them and because of them i know what to do and what not to do...just saying i learned from professionals thats all. i may only have 5 posts on here but i know what i know... spent my last few yrs in FJ community im new to FF
 
Normal zetecs can handle the same I'm sure, they have the same oil pump. Oil squirters are more for cooling from what I understand. As far as internals I'm sure it was for longevity and reliability from a manufacturers point of view (warranty claims) [dunno]
 
... you're cam timing is off. Go back through the procedure and set the cams per Crower's specs, you'll need a degree wheel to do this.
2nd that! Dial in the cams. Not sure why you didn't perform this basic necessary first step. Having built a few race engines over the years it is not that difficult and yields the be results. Without it you are shooting in the dark....
 
I dont agree at all , Only a dyno can set the cam gears to the best over all performance , your wsting your time with a degree wheel , none that I have set with a degree wheel made the best performance on the dyno , all when adjusting the gears on the dyno made more TQ

^^^THIS^^^

Make sure your cams and AFR are adjusted properly. You probably have more to gain from fixing those.

Also, build up the engine a bit (valves and pistons, in particular) if you're wanting to rev a non-SVT Zetec over 7000...

Agreed, it's the ONLY way to properly get the most out of cams stock or aftermarket.

NO NO NO NO


His EX. gear is maxed out,,, right?
So obviously the cam timing is off. If you don't understand how that works maybe you shouldn't be touching his car.
Or think of it this way, what would power do if you could move the gear more? (A: you don't know)

I don't get at what your saying no to imhell? Yes the OP needs to re time his motor. He's just saying that cams need to be adjusted on the dyno to yield the best results compared to using a dial wheel to set them. I don't think he's talking about the OP problem?
 
While dyno tuning the cam gears/cams is correct,,, that only applies if the gears don't max out while tuning them. If they do max out then the gears are off to begin with. Which means, if they where installed properly using the cam bar and such, that you have to ignore the cam bar and use a degree wheel and set by clearances to the specs listed on the cam card.
Being the gear is max'd this is the case. And it's not uncommon for aftermarket cams to need degreeing for proper installation.

Tom knows this, he just needs a slap in the face to wake him up every once in a while.
But that all depends on the customers goals and if he wants things done right or good enough.

Your a funny guy , good thing I like you , I kind of know what I am doing , he has his cam gears installed off is the only problem , they need to be rotated (installed properly) then readjusted on the dyno , Now can I touch his car ?

Your funny too.[giddy] No disrespect but....
Dialing in the cams to manufactures specs is where you need to start otherwise you have no clue where you stand to begin with. That was my point. You kind of went back in this direction I see and corrected yourself.
