RedTop Engine?

[S.K.]

That is big port engine.

Quote:Third Generation 4AGE 89.5-91.6
The next generation engines were introduced in May 1989 and remained in production until June 1991. Two types exist. The 16 valve has silver cam covers with red lettering only, and so are called red tops. These engines have oil cooled pistons, an external oil drain from the head to the sump (located behind #4 inlet and the ignition leads run underneath a cover between the cam covers.) Power is increased to 100 kW and all engines are MAP sensored. This is the final 16 valve variant produced. These engines have dispensed with TVIS and feature smaller inlet ports.

I have a small port engine, but it´s a with AFM.
