silver top sump fits, you need the silver top pickup, but the black top sump is much better, just need to cut it a bit if u are using a front starter.
ST170 springs are stiffer than normal zetec, the americans get about 20psi out of them, but you're better to uprate them.

your better of using a standard black top head with standard cams but with uprated springs with a custom inlet and this is good for 350 bhp, and if using focus rs box then use black top sump as it uses the extra holes

i had really bad valve float at 12psi on a standard st170 head. a blacktop will be much easier to get the power from and map.mine is over 350hp on a standard head and cams with a set of up-rated valve springs.
p-s really dont see why people want to go down the st170 head when the blacktop is sooo good.

i'll second crazy been in his and first time we opened it up properly for a run on motorway to stretch it's legs we pulled to limiter in fourth which was like being on my bike and after run realised we were in fifth and had actually been at 7000+ revs in fifth gear which then made us realise just how quick it is and when it torque steers you need 3 lanes on motorway to keep it straight the jump from 270-280 t0 350+ is emense and for a road car 300 is plenty

if you want it for fast road use then perhaps 350 is slightly too much
but if you want it for making records like crazycage is going for then go for it mate.
sorry didnt see the strip and track post

and that just goes to say what a genuine 350bhp fiesta goes like still getting sh*t loads of torque steer even with focus rs box decent suspension and custom bottom arms.

9months ago kriky lol i think what youve said before tho you will get it as far as you can but when you cant get no more air into the engine from the turbo i think you will get bored and will have to go gt30 
haha nah mate its an utter animal as it is.i think you should leave it as it is then i might be not to far behind you one the 1/4 miles when my engines built haha

Have a look on google at the st170 turbo's over the pond (search svt turbo)
They retain the vvt to get the turbo spooling up quicker and don't even change the compression ratio so get 300bhp at 12-13 psi on crappy fuel and that's reliable too. Some are running 20psi on the standard engine puting out around 380bhp.
Jamsport do gotech ecu's that can retain the vvt (cheaper than omex and dta)
The only thing I'd recommend is ditching the standard inlet manifold on them as they can cause problems
