  1. Bit of an odd post, but I think it makes some sense at this stage.

    The gearbox is not far from completion and I`m soon to start with the engine build for this project.  As already stated, the car will be for sale soon after project completion and there is an opportunity for anyone who is genuinely  interested in buying the finalised car to influence the specification.

    The current intended spec is as follows (with options where relevant)

    - Target weight: close to 1000Kg

    - Target power: >520bhp

    - Top speed: 186mph @ 7400rpm

    - Upgraded 918 with ductile iron liners, Saenz forged rods, CP Carrillo forged pistons, special BE shells, ported cylinder heads, stainless 316 tubular manifolds with BorgWarner EFR 6758AL turbos. Engine is running Motec M800 ECU and ADL. Twin Motec wideband lambda enabled. Exhaust is twin centre exit.

    Option to leave existing polished plenum arrangement or move to a motorsport plenum with 8-primary injectors instead of the OEM 8 + 2 secondaries. Option also to re-paint the polished plenum and cam covers in any colour desired.

    - Engine will be twin chargecooled, with two options for the system:

    1) Motorsport set-up with twin Spearco chargecoolers fitted in the boot area

    2) Pro Alloy system that preserves the boot space coupled with stock ex. manifolds and full T28 60mm compressor based hybrid turbos.

    - Will retain PAS, but water pump has been moved to Davies Craig EWP 150 electric pump and fan controller. Custom Aux belt to reflect removal of water pump and A/C compressor  Option to retain the OEM mechanical water pump.

    - Pro Alloy main coolant and twin-pass chargecooler radiator. There is no A/C fitted from the factory on this car.

    - X-Shift 6-speed sequential straight cut dog engagement gearbox with 140mm AP Racing multi-plate carbon clutch pack and slave cylinder.  Option available for steering wheel paddle shift or traditional gear level. Automatic throttle blip for downshift.

    - Penske 3-way dampers, with option on road or track springs

    - AP Racing 6-pot front and 4-pot rear with AP Racing grooved fixed discs with alloy bells (front: 356mm and 320mm rear). Mechanical handbrake

    - Wheels: Rota GTR 18x10 e35 and 18x12 e20, with Yokohama Advan A052 in 255x35 and 315x30. Spacer/Adaptor to 5 x 114.3

    - Aluminium fuel tanks will be fitted.  Option to install a foam bag tank

    - Interior will be fitted with lightweight black carpet with full Sport350 carbon interior parts still installed. Option to leave interior completely stripped and painted in a desired colour

    - Option available to include or remove the heater

    - Seats will be Corbeau carbon race seats, with Willans 6-point harness

    - GT1 arches will be visible super-lightweight carbon

    - GT1 carbon rear deck

    - GT1 carbon front splitter

    - Although the exterior colour is currently in the standard New Aluminium, it is planned to re-spray to Black to match the GT1 cars that ran in `96 BPR.  It is also planned to install the full #22 car decal set from the same BPR series.  Option would exist to do something different with the colour

    - Rear wing is planned to be a high downforce motorsport version, but option would exist to install whatever was desired.


    Rough price guide (dependant on final spec) not less than 90K€.   I would invite people who are interested to contact me via PM, but please only if you are serious about becoming the potential owner and want to discuss personalising the car.

  2. That interval is consistent with the updated Service Bulletin sent out on belt tensioning.   During the service, you might want to have the tensioning checked.

    As an aside, I have found that the Gates HD blue belts hold their tension better than the standard belts, so if you felt inclined you could use this service to swap across to those and then have a solid datum for your ownership moving forward.

  3. Hi Alex,   Are you able to share the images you mentioned in your last update?

    Later this week, i plan to take images of the engine bay parts for clarity to each member of comprising items AND what is required with the cast boost pipes on how these are modified as well and the reasoning behind why we require these supplied on this part.

    Upon Chris's suggestion and my belief that at this point it would be best to start giving weekly updates on the Group Buy of the Twin ChargeCooler Lotus Esprit system. 

    Hi Alex,

    How about the first of those weekly updates?  That was the intention almost a month ago now.

    Please can you provide us with some information and perhaps even an outlook as to when the kits may be available.

    I understand it's a big project and will take time to execute, but that is an even better reason to provide regular info on the current status.

    Kind regards,

    Mike S

  5. Having retrofitted the later changer onto the Simon Francis 97 V8, it is not only a case of getting the parts - although that alone is a challenge.    Depending on which chassis coolant pipes you have running through the backbone, it may also be necessary to customise the master unit to make it fit.

    As others have already suggested, your best bet would be to overhaul the existing mechanism.

  6. The crank sensor wires runs as part of the main engine loom back to the ECU connector (pin 79 SigGND, 73 RefHI).

    You probably won't want to unpack the entire loom, but could run a replacement pair externally if needed.  I would buzz the pair and see if you have a weak connection first.
