4AC compare to 4AFC Tue, 10 December 2002 13:59 Go to next message
What's the power difference between them?
I know for the 4AC, the intake and exhaust is on the same side.
Is the 4AFC the same?
Do they have the same block?

The 4A-F is a narrow-angle twincam, hence it will be xflow (exst on the other side from intake).
I dont think a "4A-FC" exists?

4A-C is around 70Hp @ 4800RPM.
4A-F is 90Hp @ 6000RPM.

Both do use the same block.

The 4A-FC does exist, and yes, its a carby 4A-F from an AE92.

All are twin cams but they have a single cam belt to one cam shaft, than a cog from one cam to the other, so its greatly different from a 4A-GE.

It is a x-flow head, which means in a FWD car, intake at the back, exhaust at the front.

Same block as a 4A-C, so it will mate up with the C5* gearboxes, and use the same drivers side engine mount.

FWIK all engines in an AE92 are unleaded, but i may be wrong (still driving an LRP car *sigh*)

4A-FC does exist. As haggis pointed out they're the carby engine from an AE92 (I should know being blessed with one Mad )
They are all twin cam. You guys should know how to read Toyota engine codes, come on! The 'F' stands for economy, in other words, twin camshafts. Narrow angle cams as pointed out earlier by M.W.P. The 'G' in 4A-GE or 1G-GTE or 2JZ-GTE means wide angle twin cams.
They aren't bad. A decent torque line and they are plenty quick enough in the city (but not for fun or our egos). The best thing is they're an easy engine to tune and play with yourself, which I'm slowly getting the hang of doing.

So can you put the 4AFC head on a 4AC bottom end?

yes you can but you need to change the pistons which will mean selecting a bottom end with the correct size gudgeon pins.
