N/A cylinder head from SFR. Cracks were detected in the ceramic exhaust ports of the original cylinder head. Jon Milledge did not recommend the standard 951 ceramic port head for highly tuned applications - the risk of ceramic port failure is too high.

Penguin: lol...Looks like you went to the aftermarket 944 restaurant and when they handed you the menu you just replied "Yes!"
Nice work. Should be a great fun car which is the main reason for doing all this. Sean who did all the work said "It reminds me of your old Slate grey metallic car."
Look forward to seeing the results.

Patrick I spent may years collecting the parts & there was a change plan.
My objectives were:
(1) Retain the original block so that it remains a matching numbers car with a provenance traceable back to Neckarsulm;
(2) Conceptually to be a "GT3" version of the original 952;
(3) Be capable of being driven from the UK to the Nordschliefe, Spa, Imola or Monza, lap for a full track weekend & then be driven back to the UK;
(4) Retain the full original black road car interior;
(5) Externally, be a "sleeper" which looks as stock as possible;
(6) No cage;
(7) Retain rear seat;
(8) Practical levels of ground clearance.
What changed over time:
(i) Moved from being an Alusil 2.5 litre to a Darton MID 2.7 litre;
(ii) Wossner pistons & rods replaced for 2.7 litre by Mahle & Carrillo;
(iii) Changed from the original seats to Recaro Classic Pole Position ABE in leather;
(iv) ECU changed from Vi-Pec V88 to Emtron KV8;
(v) Moved to Emtron CDI ignition;
(vi) Turbo changed from GTX3071 Gen I to GTX3576 Gen 2
(vii) Racers Edge welded Tubular Steel A-Arms exchanged for billet aluminium;
(viii) Webcam 274 exchanged for JME SR8-14;
(ix) Leda coilovers replaced by KW Clubsport 2-Way;
(x) Tial MV-R 44mm Wastegate exchanged for F46;
(xi) Tial QRJ 38mm recirculating BOV exchanged for Tial 50mm BOV.
Deviations from the "Sleeper" look are as follows:
(a) Ride height 25mm lower (max ride height for the coilovers is Front : stock - 25mm / Rear: stock - 20mm)
(b) 18" 993 Hollow Spoke Technology wheels / 18" Fuchs Matt Black forged Wheels - with 225/40/18 & 265/35/18 tyres;
(c) SFR 4" exhaust outlet & Borla XR-1 muffler;
(d) Recaro seats;
(e) Micro display / AFR LED in the cubby hole blanking plate;
(f) Carpeted "hump" in the boot over the dry-sump cover.
My goal beyond enhanced performance is factory levels of reliability & durability. The last thing I need is to be stranded 400 miles from home, somewhere across Europe in a broken car. This vehicle will be unsupported, no other vehicle carrying spare parts, spare tyres etc - the aim is to roll-up and drive, just like a GT3.
People I've consulted along the way (who all deserve my gratitude for their time & patience):
(1) Chris White (944 Enhancement);
(2) Mike Lindsey (Lindsey Racing);
(3) Tim Richards (Speed Force Racing);
(4) Bill Dailey (Dailey Engineering);
(5) Robert Gant (Gantspeed Engineering);
(6) Jon Milledge (Jon Milledge Engineering);
(7) Jonathan Weston-Taylor (Stanwood Engineering);
(8) Mark Shead (MA Developments);
(9) Emmanuel Garcia (Ferrea Racing Components).
Of course the experiments & experiences of the people on this forum have been invaluable in narrowing down options & helping plot a path.
My original project plan was divided into the following categories with the following number of line items (actions):
(1) Engine - 55 items
(2) Suspension - 18 items;
(3) Engine Management - 19 items;
(4) Exhaust - 8 items;
(5) Bracing - 2 items;
(6) Brakes - 12 items;
(7) Transmission - 11 items;
(8) Interior - 2 items;
(9) Undersealing - 1 item;
(10) Clutch & torque Tube - 13 items
Seven Project Plan Versions - total of 141 line items
All parts supplied were documented in the Project Plan plus the contact details for various specialists.
Gantspeed took a full inventory of all parts provided - although more were supplied through the course of the project as fitment issues arose or the plan changed.
Next Step - Gantspeed to fit intake filter & ducting, remove centre rib from bonnet & then car to go to MA developments for ECU wiring & mapping.
