What performance parts are available for the Duratec I4 ? Please post only the items below, and I will add them to this list. Do not discuss them here. Also, please make sure they're ACTUALLY available, or post if they're "coming soon." Please also post link of the product.

FSwerks is still around. They are just putting more emphasis on their Focus and VW parts.

Has anyone had any experience with optimized throttle bodies on the Fusion? I have been providing optimized throttle bodies for the I4 and V6 Mazda6 for quite a while now. On the 2.3L I have dyno measured gains of about 4 HP and 5 Lbs. of torque. I haven't seen a dyno from a V6 yet, but the customer compliments and positive feedback indicates a pleasant gain for the V6 also.

If anyone is interested in checking out this mod for the Fusion, I have some technical details posted at http://cordovamotorsports.com/mazda_products.html The optimization service is basically about $65 above what the part cost. (I'll need to check into the 'Ford' version of the TB to get an exact price...) If anyone has a throttle body to send in for optimization, the price is the same $65 and the turnaround time is about 6-8 business days.

twowheelin, do you enlarge the bore and add a new butteryfly or just port and optimize? I wish I could have my fusion parked for 2 weeks so I could have you give mine a try. Another question, how to you get the electronic throttle body off without breaking anything? There's no screws or bolts or I'm an idiot, after all it's been a while since I've looked at it.

I have enlarged the bore as much as 64mm, but found that a well optimized 60mm TB produced almost the same peak HP gains (4+) and provided a little better low RPM torque. (+5) Based on my actual dyno results, (Link) I stopped offering bored out TBs and only sell the 'optimized' TBs.

The TB is held on with 4 easy to reach bolts. (8mm) There is an electrical plug and 2 small coolant hose connections. (If you haven't done the bypass yet...) The Ford parts are cheaper than the Mazda parts, and I offer the same refund for core returns, so you can get a new part for pretty cheap and not have to park your car...

Sorry for the late reply. What you're saying is that I can front you $225(or less because ford parts are cheaper), get a new Optimized TB and send back my old one for get refunded for all but $65? That sounds like a sweet deal to me even if it is only +4hp +5ft/lb. Let me know when you'll for sure have ford parts to do the work.

On another note. With the coolant bypass, has anyone had any problem with below freezing temperatures and early morning starting? My fusion needs to be reliable because my Wife will be driving it with my baby in the car and I don't want to risk anything.

What's the durability of the optimized throttle body? Looks like an awful lot of material was removed. Is it still robust?

It's not really a high stress part, I don't see it making much a difference at all.

I'm testing out an optimized TB for the 2.3L Fusion. BTW: The 2.3L Fusion uses a 55mm TB which looks to be the same as the Mazda PZEV 55mm TB. Optimization will open up 17.4% more area on the 55mm TBs which would be almost as much area as a standard 60mm TB. (2211 Sq mm VS 2227 Sq mm)

We'll see if the 2.3L ECU is a little more forgiving than the 3.0L for TB changes... :huh

[/quote]This sounded like a promising mod but I haven't heard a lick from this guy in ages and afraid it's a dead issue until I hear otherwise...

thats no est bieno.i guess i might have to do what i did with my tib(bbtb where close to 600$ when they first came out) is take it down to a local machine shop and have them bore it out,new valve, and polish it. it only costed about 100$ and they had it done in about 3 hours. and it was a pertty good gain to. and if doin that i might as well get a custom pulley or two...i live in a oil town, so machine shops are pertty common around here. so there always looking for side work. i had a new x bracke done for my zam, and it honestly took a few hours,and it was powder coated and everything. guess its just an excuse to not weld headache racks together all day
