New spark plug cables! Finally! With the Bosch 2x2 coil fitted between the strut tower and the firewall I used some old Volvo cables and they barely reached the plugs. A few weeks ago one broke at the plug boot, that was the final straw to get new ones! Talked to my long time (Volvo) friends at Bijlsma Technical Innovations and they made me a perfect set. Car runs noticeably smoother with them!
Only need a set of plug boot sleeves and some flexible tubing to protect them from the local wildlife, some animals seem to love spark plug wires!
Also got a remap for the EZK from them, the previous map I used was much too aggressive at heavy load (boost) 3000 rpm up! I've always heard a small rattle inside the boost meter, especially at higher speeds.. As suspected that was detonation when the boost was building. With the Nylon tubing used for the gauge it works like a crude det can.
Lower gears it wasn't a problem, higher gears with the engine loaded up more and hotter the ezk successfully pulled timing I guess but that came at the cost of reduced performance. Engine runs much smoother now, less angry tractor motor! And most noticeably faster at highway speeds.
Also another experiment, an oil restrictor for the turbo. Not as small as the restrictors for a ball bearing turbo but at 2mm much larger. The steel SAE fitting on the turbo (same size as AN-4 but a bit stronger) was tapped for M5 thread (partly) and a small set screw drilled to make be able to exchange/remove the restrictor.
Still need to test how it works but people running similar turbo's on the Ford forums have reported good results, some cars even had them stock.
Oh and the exhaust rusted through right above the axle. Going to fab a new pipe between 1st and 2nd muffler from stainless steel.
