Hello!

Former MS3 driver here, and I've done a lot of research and lurking on this forum about the ST so I know what to expect. I'm hoping I can live with the smaller turbo and lower overall stock turbo power as a daily driver and still be happy. So far, it seems like that's definitely possible.

Well, I'll see you guys around!

I personally never had an issue with the torque steer ever feeling uncontrollable in my 2nd Gen MS3, even though I did feel its presence in general. I understand that the K03 gives me even MORE low end torque than the K04 which is crazy, but I can't help but feel like all that low end is TOO low, leaving the turbo topping out at just north of 4.5k RPMs which I'm not used to. Ah well, I'm sure I'll end up loving the car regardless!

recommend test driving a few and finding out for yourself ;)

I noticed the trq steer more in the MS3 than a ST but I notice more trq steer in the 13-14 than the 15-16 ST... they all have it but to what level.

I owned a modded Gen1 MS3(bolt ons and tune) and stock MS6 and going to the Focus ST I was not disappointed. I knew the car would not be as quick as the modded MS3 I owned but it was not a huge difference and it felt more refined and smooth. I did get an Accessport and stratified tune for my ST since I was familiar with it from my Speed3 and the car feels like it pulls a lot better then stock and more in line with how my Speed3 felt. Other then the small power difference the ST is a much better feeling car and has a much better interior.

My MS3 had an intake, turbo inlet pipe, stock downpipe, 2.5" straight pipe from the downpipe back, BOV, and a Cobb OTS tune. The intercooler was also stock. How do you think a full bolt-on ST would fare against that? Will I be getting similar power from the ST with complete bolt ons? I guess that's what I really want to know. I want power as close to what I had as possible, even exceeding it slightly if possible. If that takes E30 to do so, I will change the fueling.

Power tops out more around 5500; e30 and a tune helps. Definitely an intercooler for repeat-ability; the factory unit heat soaks after one good pull.

Slightly off topic, but why isn't there a k04 upgrade available for our platform?
not off topic at all imo.... and yea I thought for sure one of the turbo kits has a k04 option... but not really worth it. if you are going big turbo (which the k04 is NOT) then why not go to at least a 2871R?

I had a custom tune which made a huge difference from the Cobb OTS, so if you had an OTS tune I would say if you do full bolt-on ST with a proper custom tune you should be doing better then the speed3. The tune is the big difference in these cars, and an OTS tune is just scratching the surface.

That's definitely good to know, thanks man. The only other thing I had left to get over regarding going from the MS3 to the FoST was the shorter/narrower overall body length/width. Wheel spacers, wider tires, fender flares and mudflaps are definitely in the plans at some point as well as suspension upgrades. The car does seem like it'll be tons of fun and sound awesome too, so I'm hyped! Can't wait to see the potential of Ford's spin on the hot hatch. I'll most likely be getting a used 2013 or 2014 FoST.
