thanx guys

 

...remove overlap...

 

Wow Thats Rusty

 

looks like shit, do something with that rusty ass block and manifold

 

And that helps him tune his cam gears how?

They're right, though- you need to clean the timing side of your engine. That much rust on the pullies and that sprocket there won't do your belts any good. Rust on the turbine housing and exhaust manifold can't do much, but the backplate of the compressor housing looks pretty bad.

As for the cam gears, you can't just randomly adjust them. You either have to experiment with them on a dyno, testing small adjustments until you find the best setting for power, or degree the camshafts, which involves a lot of work finding valve timing events and adjusting the camshafts until the events precisely match the cam card. This last one is something there have been threads pages long describing, and I can't give you any more detail because what I just typed is about all I remember from the last one I read.

 

In his defence the motor has been in the car and it doesnt look like that...

as for the aem gears.... I have no clue. Maybe Rob or Dave might have something to say..............

 

thank you dario yes it is on a motor that i got out of a junk yard . some people cant tell that the motor in the pic is a example (brandon) you allways got a smart comment.

Question- are you on stock cams, or aftermarket cams?
