  1. Dear All, 

    After 8 years of good fun and challenges with the 1998 Lotus Esprit GT3 it is time for something new. 

    So therefore it's up for sale. To give the forum members a chance UI will list it here first exclusively for a while before it will be listed elswere. 

    The has has 79k kilometers on the odometer.
    Engine is tweaked to ~320 hp (Attached the graph)

    Summary of the upgrades,

    Quaife LSD

    EFi Euro 4 ECU (Incl USB module)

    Deatchwerks injectors

    Alunax tubular manifold

    Engine rebuild at 70k km with light weight conrods 

    Upgraded clutch

    Calibration at DPengineering Boven-Leeuwen (Now calibrated on throttle position, runs very well, good cold start and no pops and bangs)

  2. If you are not running the operating point close to the surge line at any point i the compressor map it will not bring much benefit. Pre-swirl only shifts the compressor map. For efficiency the pre-swirl vanes are only another drag increasing component within the air system. 

    As both the I4 and V8 Esprit engines don't take a extreme amount of boost a situation that a compressor is benefitting from this pre-swirl system is very rare. Beter is it to select the best compressor and turbine combination to improve performance. Also a straight inlet before the compressor inlet important and overall as less restriction in the inlet as possible. (With a downside of increased intake noise)

  3. Hi Erik, 

    I know Lotus bits have experience with racing their sunbeams, but racing Esprits I'm not sure. 

    The original X180 were made by safetydevices in the UK. http://www.safetydevices.com/ but I don't think they have any data. 

    This cage was a bolt in cage, https://www.classicandracing.co.uk/projects/lotus-esprit-turbo-race-car/   but difficult to judge if it is compatible useful for a roadcar. Nevertheless it would be a great base for road cage. 

    I build a custom cage in my Esprit S1 racecar, but that process would mess up the interior and only works if there is a body of restoration. 

    If you have any idea to make a kit that can be fitted in a car with remaining most of the interior that would be great.

    Otherwise i think it is just as easy to make a custom unit for each individual car by a local company if you take the engine and interior out.

  4. It;s a bit of a guess, but it could very well be that the strange bits are not to hard to take off and you find the original bodywork underneath.

    Much more so at the rear and front spoiler. The front bumper area would take a bit more work. Nothing too bad for a GRP specialist.

    My guess, Excluding new (SJSportscar) GRP and other parts but Including total respray, could be anything between 5000 and 10.000 of work to get it back in the original shape and color.
