This is 1970s saloon car racing in JB, this silver car has a schnitzer twin cam M10 with Kugelfischer mechanial fuel injection (similar to the Brabham BMW F1 engine from early 80's) Silver 2002 racing with a wild mix of 70s cars... I see minis, MGs, Lotus 7, Lotus Elan, BMW E9 CSL ....must have been fun to see...
Awesome photos, but I thought Pasir Gudang circuit opened in 1986. BTW, I think picture 2 is BMW corner
Maybe it's the 80's. I am surprised they still use the 2002 body then....but the engine certainly looks like an early S14
