Hi all, his name is Spike and he has the following spec:
G-Tech - GP/R 1.5
Engine rebored to 1500cc
G-Tech Roller bearing Turbo
9.4:1 Forged pistons
Cryo treated, balanced & polished conrods
Larger fuel injectors
Two larger intercoolers
Silicone boost tubes
Sports air filter
Exhaust system straight through no silencers, 200 cell sports cat
Replacement fuel pressure regulator
Custom G-Tech ECU
Stronger clutch
Single Mass Flywheel
Iridium Spark Plugs
Custom ground camshafts
Ported Cylinder Head
Exhaust temperature gauge
Quaife LSD
Brembo 4 piston brake system with 305mm front brake discs
KW Variant 3 coilovers
288 hp / 299 ft lbs torque
Next step is a cage, OMP seats, harnesses and for the summer a grippier wheel/tyre combo.
Should have some vids up on Youtube soon.

To answer some of the questions, best I've had out of it is 55 mpg and I averaged 52.5mpg over 150 miles on a run across France. It's done a 1000 miles at 43 mpg so far. I'll post up a pic of that 52.5mpg run. It's pretty astounding economy but if you're off the turbo it's a lightweight car with a 1.5l engine!
As for torque steer - it has none - none whatsoever. The only time I experience any is when the front tyres lose grip in the conditions we've got at the moment. Before the bad weather set in I could use full power everywhere and absolutely no torque steer. The Quaife LSD seems to do a magnificent job. By comparison a Golf GTI / GT TD torque steers all over the shop.
The wheels do look shopped in that picture but I can assure you it's how it is. I think the KW coilovers make the wheels really fill the arches now so it gives that impression.
As for the engine bay, not much point in a photo, it looks almost standard. G-Tech modify the car to get compliant under TuV so even the cat bodies are retained, but a 200 cel core is put in place of the original core. It's a really tidy professional job. Will take a pic soon anyway and post it up so you can see the differences. You can see the bigger turbo but not a lot else is visible.

must say "no torque steer whatsoever" is very hard to believe, how can it be quelled completely? with similar power, a quaife diff, revoknuckle suspension and after spending millions in r&d ford didnt manage to get rid of it all in the focus rs.perhaps it is less than in the golfs you have driven and so it feels minimal although with all that torque it is some trick.
im not doubting you believe what you say and perhaps it is a very small amount, but kind of doubting of its possible to have that much torque in a small fwd car and have no torque steer whatsoever in dry conditions.
either way i hope you are enjoying it, i bet its a blast.

Is part (or all) of the Focus' problem not that the driveshafts are of significantly unequal length?To the o/p: epic car, absolutely love it

Thanks for all the comments everyone. Yes, it really doesn't have any discernable torque steer at full boost and I realise that is pretty unbelievable but it's true. I'm not an engineer, but also remember this is about 400kg lighter than an RS so maybe that has something to do with it, or as someone else has mentioned the physical design might be the issue. I own and have owned a lot of performance cars so know what torque steer is. I was fully expecting it to be a torque steer monster but it isn't and I can't explain why either. I will ask G-Tech why they think that is, perhaps they will know more.
As for cost, it costs more than an RS to put together, around £28k so far. Sure I could have bought an RS but it is not my cup of tea at all and as I said on another thread, this makes me chuckle. No one expects this little thing to go like it does but in my book if a car makes you giggle like a little kid it's a good 'un.
To answer one of the questions boost is a touch under 1.8 bar. EGT doesn't go higher than 900 deg even after a hard run. That's lower than stock temps.
I'm thinking of ditching the stickers to make it even more stealth but that will come behind the other mods I'm making as I'm intending on tracking it this summer.
