I grabbed this fully-loaded Focus ST that suffered an engine failure last Friday. Got it refreshed with a used motor replacement with a ton of other bits it needed over the last 9 days to get it ready for a new home. This one already had a bigger turbo installed along with the usual bolt-ons.

Along with the engine, it just recieved a new alternator, starter, LH inner/outer tie rod, flywheel, RS clutch kit, RS slave, heater hoses, waterpump, thermostat, front o2 sensor, serpentine tensioner, idler pulley, both belts, separator plate, all gaskets/seals, spark plugs, axle seals, front end links, oil/filter, coolant, and had the headlights restored.

The car:
2014 Focus ST3 (79,500 miles) in Oxford White with heated, full-leather power Recaros, 10-speaker Sony speaker system with subwoofer, dual-zone auto climate control, 8" touch screen, ambient lighting, Bi-xenon HID projector headlights, and power sunroof.

Modifications:
- ATP Gen2 GTX2860R (.64) turbo kit
- COBB 3" intake and 3" catback
- Whoosh 3" catless downpipe
- Mishimoto intercooler/hotside piping
- CVFab cold side pipe w/ Turbosmart BOV

If anyone is interested, it will probably be listed for $13,000. Clean title in hand.

Alex's Fiesta ST in for his big turbo upgrade!

Turbo Technics S280 w/ Turbosmart wastegate, Whoosh downpipe and intercooler, Velossa Tech snorkel, and a Damond rear motor mount!

This is the perfect pump gas setup and he chose a the right parts himself.

A couple cars on their way to the dyno this afternoon after some pretty extensive work.

The black Focus ST on the trailer got a new ATP GTX2867R Gen2 turbo kit, heater hoses, thermostat, E-brake cables, spark plugs, valve cover, tensioner/idler/belts, a shift tower reseal, and some exhaust adjustments. It should make 330-340whp on 93 on a conservative 93 tune per our request.

Tyler's Nitrous Blue Focus RS had a timing cover reseal, new valve cover gasket, PTU seal, and an NX2 turbo w/ Turbosmart wastegate, a downpipe w/ new OEM o2 sensor, a replacement passenger rear ABS sensor and an oil change to top it off. This stock engine should make 400whp on 93.

Honorable mention: Logan's Shelby GT350 is being picked up after having a McLeod RXT ceramic twin disk installed. After some break-in miles, it will be ready for more autocross abuse this summer.

Travis' Focus RS delivered to the shop here in New Hampshire all the way from COLORADO!

Unfortunately, this car has experienced what a lot of high-horsepower builds do. It was originally built by a popular EcoBoost company using a new Twinscroll 2.0L block a couple years ago and blew a headgasket sometime last year. The head was resurfaced and gasket replaced and within 6 months, the block cracked. 🫠 The car is using a PTE 5862 turbo making around 550-600whp and the newer 2.0 TS blocks just cannot structurely handle the pressure/power at this level, which is why it will be rebuilt using a 2.0 Focus ST block this time around. While it's here, I have the opportunity to straighten out any hardware discrepencies and re-tune the car if he desires.

Having a good relationship between your machine shop/engine builder, mechanic, and tuner is a major factor as you strive for double or triple the factory horsepower in a build like this. Nothing is perfect. But when all parties agree, you have the best chances of success and reliability.

Money spent on recommended service/parts/tuning to reduce risk is an investment, NOT a cost!

Here we have one of those special edition Focus RS that has twice as many cylinders, permanent drift mode, and a snake badge... In the shop for a McLeod RXT twin disk clutch kit install! 🐍

Mike's Stealth Grey Focus RS on the dyno this afternoon to see what his new Precision Turbo & Engine NX2 turbocharger and Xtreme-DI LLC HPFP35/2000cc injector combo is doing for us! This car is still using the original engine with 55,000 miles, all the bolt-ons from Extreme Turbo Systems, and an Advanced Clutch Technology FF5-HDSS organic clutch to take the abuse.

Justin Brasil at Freektune got it dialed-in on pump gas with 407whp/411wtq and added some ethanol to the tank to see the full advantages of this turbo/fuel system. Www.freektune.com

This car exceeded our usual goals, making 443whp/446wtq so we dialed it back to 424whp/427wtq where we believe this engine will live a happy life for Mike to enjoy as his daily driver.

Thanks to JP Alonso at Edge Autosport for offering his support to fill the demand of Precision turbos here at the shop! Www.edgeautosport.com

Who's next? 😏

Tyler hit me up a few weeks ago asking if I was willing to re-seal his timing cover on his Focus RS. Now this is probably one of my least-favorite jobs on this car for the sole reason that if it does leak again, I lose my shirt and have to do it a second time and not get paid (f**k that s**t). I explained to him I like to lower the engine to ensure the highest quality result possible, and he decided now would be the best time to upgrade his turbo while I was there. We fitted a Precision Turbo & Engine NX2 turbocharger and will have this thing sealed back up in no time so he can enjoy his new 400whp (on 93) setup with no more oil drips!

Thanks Tyler for trusting the process. 💪

Brad's Focus RS engine suffered some rapid unscheduled disassembly a couple years ago while he was still living in Washington state.

He moved to New Hampshire recently and trailered the car with him to his new home where it has sat under a car cover in the driveway.

A this may be a bit of a project for a shop unfamiliar with these cars which can make owners a little nervous, but it is just another day here.

A new OEM Ford 2.3L long block is being installed along with an ACT flywheel/clutch kit as well as some other service items while the car is here.

I have been VERY busy the lasy few weeks. The nice weather is here and owners want their cars faster, lower, louder, or just fixed! New projects are showing up here every single day and a ton of people have been stopping in.

Diagnostics, EVAP repairs, fabrication work, turbo installs, clutch replacements, big power builds, brake upgrades, engine swaps, preventative maintenance, and resolving issues caused from other shops all happening.

Right now I am booked flat-out for the next 2 weeks, if you need something please reach out ASAP to get in the schedule loosely. Tow-ins are always welcome and will be tended to right away.

Thank you! 💪

Oil pan re-seals/replacements are always fun when the engine is still in the car. Gravity is constantly working against you, pulling oil downwards into the area you are working, no matter how long it has been drained for. The mating surfaces must be completely clean to ensure a perfect seal, and even the smallest bit of oil can ruin the entire day you've spent.

Client was unable to dodge some debris on the highway and it poked a hole in the pan about the size of a grain of rice, so I am replacing the pan.

The best way I have found to fix a leaking oil pan or leaking rear main seal is to do both at the same time. Unfortunately the transmission, clutch, and flywheel have to be removed so it is no simple task.

Do what works best for you!
