Put nitrous in it Geoff!
Re turbos, transition to boost is much smoother on the 177 hp engine, due to the smaller turbo. The 170, easily identifiable by the twin butterfly throttle housing, is more switch like and could catch the unwary out in the wet, however the ignition pulse sensor on the 177, I now refuse to call them series one or two on the same principle that there was never a mark five Cortina, is as rare as hens teeth and if it fails you could pretty much guarantee that your otherwise pristine 924 turbo will not get stolen as it will be completely immobilised with no spark, and slim chance of repair, as the sensor is unavailable and has been for at least ten years. to my knowledge. Don't let that put you off though. Either car is a hoot as they are frequently mistaken for 924 n/a and the look on peoples faces when you open them up..... As many will know I am currently working on a 220 upgrade to my 177, with new cam profiles intercooler raised CR, reconditioned brake calipers new discs etc. The project stalled for eleven months due to the failure of my sensor. Luckily I found one in the last place you always look, under my nose, so the project is on again.
You pays your money......
