We spent a lot of time with timing adjustment and finished with these exact numbers:
We used valve clearance:
intake
0.20mm, -+0,05
Exhaust
0.37mm, +-0,05
Timing regarding N1 cams and factory instructions should be 110° intake / 122° exhaust – both on low cam
Timing was quite off when We set as it was from the factory
We finished with: 111° on the intake, 117° on the exhaust side
valves opens +- at the same point as are the factory specs =
Intake Low: Opens at 0deg before TDC, Closes at 40deg After BDC
Exhaust Low: Opens at 64deg before BDC, Closes at 0deg After TDC
What is strange - when We have exactly measured low duration of the cams , it´s differs a lot!
Many thanks to you guys!
and why 18´s? Almera kit car also had 18´s for asphalt competitions... I need much more grip and have 225/40/18 size in the vehicle registration. Those wheels are very light /only 7.2kg per Wheel/ and wrapped in Pirelli Trofeo R tires /225-40-18/
