184bhp Westfield 1.6n/a road legal

Recommended Posts

*Video added from last visit to Northampton Motorsports




















For sale, my Westfield SE independent suspension – originally built from kit by previous owner in Summer 1996. I bought the car around 2007 and somewhere in the house I have copious amounts of original paperwork – instructions, registration correspondence, etc. This will be provided for review before sale.


The engine is from a Vauxhall Corsa GSi (1.6 16v, x16xe/ c16xe - the differences between the 2 original engine specs aren't fundamental) currently producing around 184bhp at the flywheel. The induction roar is lovely, beyond that it's utterly ballistic until over 8000, when the dash warning lights indicate change.


The car was stripped and rebuilt, completing Q2 2014, since which the car has covered road only miles. The entire car was stripped, the chassis was reinforced with additional tubing, chassis and cage repowdercoated/ repainted, new lightweight bodywork was fitted, new carbon panelling installed (dashboard, tunnel top and sides, rear bulkhead/ front bulkhead), new racing battery, new lightweight seats, engine bay undertray were fitted. 


Selling for the following reasons: -

  • This would make a great competition car. However, I’ve realised that although I like sprints and hillclimbs, I’d much prefer to pay another owner, turn up, jump into a fast, well prepared car, leave just the right amount of rubber on the track, get as much out of the car as possible, cross the line in the full knowledge that I’ve done my best, applaud the winner, party a little and then drive home in a "normal" car (neither a motorhome/ nor with a trailer).
  • For the 50 or so miles to work and back, I actually prefer driving my automatic (I know, you’ve just stopped reading). It just means I get there more relaxed and better placed to manage the daily battle.
  • I haven’t got the time and this is unlikely to change. I get the car out for about an hour per month, if I’m lucky/ if the weather’s good/ if I’m not working the weekend. I am just not doing it justice.

What a beautiful piece of kit - potential buyers, don't just look at the headline figures; the combination of power, gearing and weight will make this a very surprisingly quick car, with lots of very expensive bits on it...!
