This Vectra, even at these power figures (and it can make more), has so far been reliable and it is my wifes daily driver. A five mile round trip in town traffic. Monday to Friday. If I am going to Scotland or the Midland I will commandeer it and take advantage of the fuel economy if the power is not used too much. Also the load lugging space. Totally nothing like undrivable and a pleasure to drive, relaxing and listening to Radio 2.!!!
The items that have required attention were a replacement inlet manifold, which I ported, when we first got the car. There was an issue on the injector wiring loom which may be common to other Vectras. This was an easy no cost fix. An issue with one injector which resulted in all four injectors being sent away, rebuilt and new nozzles, got stung on this and will not use that subcontractot again. As far as the engine is concerned that is it.
Ball joint last week, odd bushes previously, brakes, discs Bilsteins and Eibach and away you go.
I first went to A RR Day at RSTuning 05-02-11. 205 bhp without 50-50Water methanol injection and 216 bhp with. I think it was around 348 lbs/ft at that time. Mapping and an understanding of the ECU is as important as the hardware and on the same turbo at RSTuning after mapping 13-04-11 the car did 217 bhp no water/methanol and 230 with 50 :50 water methanol. I am now on my fourth incarnation of the original 17/49 VNT turbo having tried a disastreous 17/52/56, 17/56/60 great power but too far up the rev range (2,300 rpm) No use for a comfortable town car and currently 17/56/56. Good power well below 2,000 rpm. All the figures I quote are from the RSTuning rolling road.
If I purely wanted to produce good figures and bottom end was not important to me then far greater power would already be achieved but I want to retain this as a car that can drive round town well below 2,000 rpm.
With a colleague we are well on with a further turbo incarnation and shortly he will be able to offer a small range of hybrid turbos for specific applications on these engines based on proven results. All results have been documented on the same rollers which many claim are conservative.
No doubt I have more interesting information for you but in the meantime please let me know of the reliability issues suffered on these engines/cars with 888 and DTUK experiences.
