Ha ha... I get asked this all the time! 8)
I bought the car from a 45 year old guy who had basically owned it from new. It still has a 180k speed cut, 440cc injectors, stock fuel pump, no boost controller etc... It had a standard exhaust with cat when I bought it. Its honestly had no work done on it at all which really annoys a mate of mine who has a completely re-built rex (forged pistons, rods, race bearings, big turbo, injectors, FMIC, Fuel pump, fuel reg, link etc etc...) his car runs 17 psi and only makes 216kw (on the same dyno).
