What did you do to your Fiesta ST today ?
I never thought to do a "How To" on this project so I didn't take photos along the way.
I used the M7 catch can because I bought it for a previous car and never used it.
I chose to place it in the rear corner, right side, of the engine bay because it fit and provided the shortest hose distance.
I ordered an additional OE PCV hose because I wanted it to look as close to OE as possible and it was only $12.00.
Cutting the original hose and adding pieces of the second one I was able to route the hose as shown above.

Sorry don't have a dyno anywhere near here, not expecting a huge bump without a stage 2 tune and even then I'm not expecting too much. I imagine it'll come into play once more mods are done especially a bigger turbo.
The measurment of the core is:
Stock - (L/W/H) 27 x 1 7/8 x 5
GodSpeed - 24 x 3 x 7.
The godspeed isn't as long but the pipes out of the end tanks are not near as restrictive as the stock unit.
Here's a side by side

For what its' worth, I fitted a larger intercoole 24" x 6.4" x 3", ran it for a while then did a dyno. After fitting the cooler, the car felt dead. Did some logs and found that at higher RPM's the car was boosting 0.3 bar less than with the stock cooler. This is with a stage 2 tune. I took the thing off and went back to stock cooler.
I would only fit a bigger cooler with a turbo upgrade. It's not as if I rag the car all the time, so heat soak is not really and issue, I also dont track the car, where a better cooler will benefit more. I am rather going Water Meth injection with stock cooler.
My 2c.

When it gets hotter as summer goes along if you want to seriously track the car or make an extended mountain run, etc.....that is where the bigger IC is going to be the most important even on a stock turbo most likely. Testing on a dyno or real world driving in not really hot weather, might give up some power but loose less when it starts to really get hot and you are pushing the car, watch the water and oil temps then as well of course.
The stock turbo is just a bit to small for the engine size and will be straining to make full power meaning more heat generated, adding the bigger IC can make less boost as has been seen on one car so far that I have seen posted, here, just not enough turbo to overcome it.
Upgrading to a bit bigger one and there has to be some reasonable cost ways of doing this will help build a better power band, more HP and less strain on the turbo as well.
I love this little car but Ford did some really odd things, turbo to small, insanely restrictive downpipe, maybe they were concerned with us beating up on the FoST so they throttle the FiST back on purpose, not much else I can think of for doing things this way. It would of cost them practically nothing to have a bit more turbo, a bit better DP and a bit larger matching IC and radiator as well.
One reason I bought the car was the factory turbo but the only thing I am retaining is the manifold when really needed and was ported well by me and the internals of the engine, I am changing just about every other part and not going after nuts power, just a really nice usable power band that can handle the heat on track on hot days, climbing a mountain pass, etc.....then a bit more on top of that.

It's only 1.6l... the turbo is adequately sized for super-quick spooling. If it was bigger we'd have to wait a lot to come on boost and it would feel sluggish down low.
I had a K04 on my 1.8t Passat years ago and it had essentially NOTHING until 3K and then it was full 21psi and wheelspin galore. It was fast but wasn't super fun because of that digital feel of boost delivery.

In my opinion of course:
Super quick spooling, torque peak is far below optimum and then it runs out of steam at higher RPM, not really a great setup. A slightly bigger turbo would smooth out the torque curve, give a broader power band and more top end. I have sized turbo's on a few custom NA to turbo builds and upgraded turbos on FI cars and had great powerbands that were easier to drive
I have also detuned the top end in the name of reliability when I had more than required for the job but would of gone to a smaller turbo if needed.
Go very big, then you get that dreaded lag and bigger overall numbers to brag about but a pain in the arse to live with and sometimes outright dangerous because you cannot get out of the way in an emergency, to much power under limited traction situations, etc......it is all about balance, in all things.
A perfectly sized turbo, properly tuned, would greatly benefit this car enhancing drivability, when done right.
I have built some very fast, fully sorted out, chassis, brakes, suspension tuning, then dial in just the right amount of power and beaten tons of cars with far more power.
250 WHP and ft lbs with a wide powerband is plenty to make this a very very fun car and easy to drive, I want a bit more but also am taking the whole car to a bit higher level than most will do and want around 275 or a bit more of each but too much will degrade the overall balance of the whole package. I will not sacrifice drivability for it.
I want power available all the time, I can live with a very slight amount of lag but not much at all and prefer none when possible, there is plenty of room for a bit more turbo on this car and achieve that.
I just wish somebody would step up to the plate and offer it in a reasonably priced and reliable package.

This post is a bit redundant so I will clean it up later, I have to go right now.
