Best quality pics I've seen so far. I think the Cobb is the best looking too. On a side note... Are those stupid tow ring arrows some sort of spec thing because they look stupid.

Its so the towing crew doesn't rip out your radiator core support or something. If you have the ring you want them to find it.

Any way, I'm anxious to see for myself tomorrow morning, SEMA here I come!

The cars were cool and a few STs I haven't seen any new pictures of were the ST Octane Academy cars which have a dual brake caliper and hydraulic hand brake setup. I should try to take a few tomorrow.

Good news: Borg Warner is releasing a dual scroll version of their smallest EFR turbo. That should mean an even quicker spool than the current model so a sub 3,000 rpm spool might be possible together with close to 400 HP potential.

There was a Fusion 2.0 EcoBoost with an EFR turbo and that looked pretty cool. So EcoBoost with an EFR is starting to become a known upgrade path.

I need to see if Bosch is there so that I can ask about the high pressure fuel pumps. And go back to Ford to ask questions about the Sigma engine.

I also have to try to find BFG and tell them to make a Rival that fits the ST.

Lastly Optima is running their ultimate street car challenge. The competitors looked like some serious stuff but the event is three parts, an autocross, brake test and then a hot lap on a track. I think a 300+ HP Fiesta ST would be a contender in the first two and not that bad in the third so if I've got an EFR, big brakes and sticky tires I might try to get an invite.

Any way, I've seen a lot of cool stuff at SEMA so far. Now I'm going to look for dinner and maybe a show.

i had hoped that there would be some info from some of the vendors about hardware available, downpipe, turboback. intercooler package. i had hoped cobb would have something definite.

about the turbo upgrade. the first thing is that it should be a stock replacement. in other words, you take out the stock unit and you replace it with an new unit. fits in the same place with no special add ons. i would like to go the same general route as my WRX. i went from a stock turbo to an evo III 16 g which is a modest upgrade for that car. i'd like the same what i call stage III bolt ons. and a tune to go with it and access tuner race to fine tune it with.

even if a new turbo comes out though i will wait until someone else tries it out to see if fueling can keep up with such an upgrade and if not what the solutions are. i would really dont want to open up the motor for a cam change. in fact that might be a show stopper. bigger injectors might be ok depending on how hard they are to swap out. i did that on my wrx and it was not too hard. but those units are not high pressure.

interesting, if you check around, there are upgraded injectors for the FOCUS st. and i wonder if FOCUS injectors would work on the fiesta st. Both are dI.

assuming power upgrades are possible, i might be interested in the limited slip diff. but thats most likely a no no due to the complication of installing it.

finally, i have had custom ground-control suspensions on two cars. i already called them and asked if they were gonna do something for the fiesta st. so we'll see. i want a slightly stiffer suspension. i'd like it adjustable and i'd prefer to be able to raise it up to stock height for various reasons..

The Borg Warner KP39 is so tiny that there will never be a drop in upgrade turbo. Its not going to happen.

Luckily the EFR turbos are also Borg Warner so they have integrated wastegates and boost control solenoids so I was told its a straightforward conversion from the Borg Warner on the 2.0 EcoBoost (K04 I think).

For a turbo upgrade its going to be all or nothing because less than a full system upgrade is going to leave a huge bottleneck somewhere. Basically all the hot side plumbing and a lot of the cold side will need replacement or serious modification.

Injectors are an interesting question but I think the challenge will be more with the volume of fuel the pump can support. There is so much pressure in a direct injection system that I doubt the injectors will limit the engine before the pump does.

Any way, Bosch does not seem to have a booth so many of these questions will go unanswered until someone runs in to the limits.

from another forum... where the kp39 is used (vwtdi)...

BorgWarner kp39 and some bv39 are prone to fail due to construction flaws.

On engines equipped with these turbos I wouldn't even consider a standard stage 1 tune.

If tuned they turn into a ticking time bomb, they are one of the most common failed units I get from customers in my workshop, and most of my customers drive completely stock cars, no tune or something like that.

Those turbos are made for quick spool, lightweight and therefore weak rotating assembly with super thin shaft, small bearings axial and radial, undersized in every point of view plus an fail constructed compressor wheel, weakened exactly at the point of highest load/centrifugal forces. ( see picture of JFettig, that's an typical failure - compressor wheel burst.. )

Tune them, use the extra power - wait for boooom. It's just a matter of time....

For some application there is even an OEM Garrett replacement available since the failing of the BorgWarner units is a well known and common issue.

Well that's always nice to hear. :/
yes i was bothered by that since i plann(ed) to get the cobb unit. if you dig a bit, you find that there are immediate replacements for that turbo for the vw folks that produced better tuning results and that are more robust. one had a slightly larger coldside. these were garret turbos. and they are direct replacements. which means that the same turbos can be adapted for use on the fiesta being of the same physical size as the stock turbo. it just takes market interest. this is what happened with subaru WRXs. popular tuner car so turbo aftermarket started making bolt on replacements that fit in the same location, bolt pattern and hookups as the stock turbo for existing turbos that were used on other cars.

here's a garret vnt-17 with a compressor from a vnt-20 supposedly produces quicker spool than a straight vnt-17

That doesn't look like it will fit a Fiesta.

If you have to wait for Garret to tool up for a drop in replacement, it may be a long wait.

I haven't seen anything suggesting that Garret has or is planning on making something like that. On the other hand I wasn't looking specifically for that because I wouldn't want an incremental improvement from a replacement turbo, I would want a significant improvement.

my experience with other cars is the aftermarket will take a turbo like above and machine it to fit. not garret. and im not sure what the difference is between incremental and significant. thats in the eyes of the beholder. i went from a car with 220 hp at the crank on a 2.0l to a one with 390 or therabouts at the crank on e85. this is what i what i describe as incremental. a similar upgrade to the fiesta st would exceed 300 at the crank. my guess is that around 250 many folks would be satisfied and i suspect that turbo above or something similar would produce such gains.

time will tell as tuners start searching for the limits of this car. atp turbo has already stated they are working on turbo upgrades.
