Hi all,

I am new here. And I have a serious problem with my setup.

I recently helped a friend, who owns a Lancer 4G92.

I changed the block, pistons, connecting rods, crankshaft with 4G94, and only the cylinder head I am using back the 4G92 MIVEC.

The engine starts, but at idling, each time when I step on the accelerator, it keep knocking. What seems to be the problem? Do I need to do other modifications? Or anything else to solve this problem. The power is also not so good when I try to rev the engine hard.

Any advise would be much appreciated. Thanks!

Cheers,
Simon

 

is your timing correct?

 

Yes the ignition timing has been adjusted to as low as 5 deg BTDC. And when strobed with the timing light, and tried to pull the throttle by hand to get the knock. Noticed the timing is retarded a while before it goes back up. Is this normal? The knocking happens when the timing mark on the crank retards.

Thanks.

Cheers,
Simon
