The thing is ITB's are such a restrictive option that it'll be custom made. Its kinda a no brainer that it'll make more power but ive seen maybe one example of it in over 8 years now. do you have a link to a kit that'll work in a focus chassis?

Well ether way here. This is pretty much a must have list of parts for a wicked N/A and when i mean wicked going beyond the basic I/H/E. If you want more power or more power a cheaper way then you need to go FI. Of course if you do all of the N/A or most of those steps you will end up with an even badder @$$ FI car.

The Lotus/Caterham guys swear by them if you plan to rev over 7,000. Could save your motor.
Cost about $50/set.

Oh, and ITBs (if you can fit them) ; )
most forged rods come with arp's, well at least my eagles did!
i got a question. does the machine shop oversize the stock valve seats, or do they have to put in bigger ones for 1mm oversized valves? i wonder how much extra it would cost with the 3-5 angle valve jod?

IIRC, yes, they do. the 5 angle valve job will only help w/ the valves seating more evenly. and IIRC again, it was 30 bucks more, but it will vary from machine shop to machine shop.

The exhaust will fit except for the tail pipe. The sedan requires a longer tail due to the longer body.

The seats have enough meat for the OS valves.


The valve job you have to talk with your local machine shop, prices vary and just because one paid this does not mean that is the going rate.
I called 6 machine shops for machine work on my SVT head, prices for deck and 5 angle ranged from $175 - $300 but where all tenative on parts.

What I did find is that the SVT head is a 5 angle stock, far as I can tell.

Excellent info guys. Very helpful in pointing some one who doesnt know much about the focus (such as my self) in the right direction. All the upgrades are pretty much standard with most 4 cylinder NA builds but what i found really helpful was the links of where to get the parts and the mention of the companies that make parts for this car. Thanks guys
