This is bringing back memory's , such as about ref cv, mine eat them all the time so I just stopped replacing them and run shit ones, also for afters lol was rotar cap + arm every 3 months ( same cap as a cossy) , if you run more/ loads of boost without a fuel regulator upgrade then the manifold may crack , a chip for the mk1 was a bleed valve (maybe different on a mk2) there was a proper upgrade ecu for the Mk1 from Italy at £1400 , also the Mk 1 had two types of box ie under floor linkage or through the car linkage ( under floor run a 17 spline clutch and the other a 20 spline, as this is identified by the spares number / second vin plate on the slam panel) my mk1 was dame low( I was young ) and it would belly out the box hence popping holes in it which the only road side fix was fibre glass resign , also my boost went of the std gauge , and the bloke that had it after me put a proper gauge on it and it was making 23psi and I fun it like that for 2 years plus with no problems , I would have another but it has to be mk1 as the engine is far better than the Mk 2
