  1. I think its just microswitch and you can measure it just with multimeter. I have opened some and just cleaned it. Some has actual microswitch in and its generally used part and separately sold in any electrical shops. Not seen potentiometer on any of my cars so far. If there is aftermarket ecu used then there could be potentiometer. Not sure about USA sold cars if they have. But its bretty easy to open and see if not sure.

  2. Engine type is diffrent on those (Chrysler 1.6, 1,8 and 2L) talbot and matra na engines . But yes, same gasket set is mostly parts suitable also on 505 turbo engine. N9T Is only turbo version type.

    Fex. 7T2 is 2L chrysler engine, 9N2 is 2,2L talbot/matra engine and N9T(E) is turbo engine used on 505 and citroen 4TC (BX B group)

  3. Basic engines are same from 150-180hp. Only diffrencies was. 150hp was no intercooler -84 models. 160hp was intercooler one -85. from -86 there was 180hp with or without lamda and cat depending country specifications. Some -86 -> -87 was with 160hp (sweden and switzerland). Not sure about us versions. 160hp version is 0.6bar and 180hp is with 0.8bar. So engine code does not mater, from 176 A -> C are basically same engines.

  4. Time to look winter tyres from storage, found my 14" old winter tyres with basic plate metal wheels. Noticed at I have some 15" sets without tyres and asked from local tyre supplier if they have some free intermediate tyres to use just for fun and before for real need for winter tyres with spikes. So they called few days ago and I give my wheel set and today I get my set back. Cost was 20e :D Michelin lattitude gravel racing tyres.

  5. Some update. Volvo pistons machined -1.8mm and piston head reshaped to match original. Fitted on block and now just waiting for custom head gasget to arrive. Ordered that custom head gasget from italy with separate fire rings. Same gasget as I used with that larger piston engine and same whitch Tama uses currently in his same way build engine (same 92mm volvo pistons and saab B201 conrods).

    Here is some pictures

    1. after

    2. Pistons before machinery

    3. mold mass testing for valve clearange (not hit at all even 0mm valve setting)

    4. own build dani head plug seat detail

    5. pistons assembled and front cover with gears and chains assembled

    Seem at pressure ratio will be bit lower than I previously assumed and calculated but it will be still close to 8, piston is now 0.5mm above block when in up position.

  6. taken from document

    SAAB Turbo 16 valve cylinder heads were then fitted on top. This is where the team had a real revelation, made possible by the construction of the SAAB cylinder heads. If you pointed the heads the same way, so that timing gears were on the same side, it meant that one head would be positioned correctly but on the other side the exhaust ducts would face inward and the intake ducts outward. This, obviously, would not do. Instead of manufacturing a custom head, which could have made the production costs unsustainable, there turned out to be a simple solution. On the problem head intake ducts were converted to exhaust ducts and vice versa
