Sedans Rule!
That's exactly what I was wondering... If so it can't vary much, in fact is the added parts/complexity even worth making it variable flow?

Don't know,
One thing I've noticed over the years is GM doesn't typically do things they don't have to. Meaning if there is a 2 cent washer somewhere, its probably needed.
They often don't do things they should for that matter cause it costs an extra fraction of a cent.

3.8 buicks had a gear type pump off the front of the engine.
pumps like that are used in auto trans a lot too, ls engines have that style of oil pump
In a 4l60 they have kits that have different amounts of vanes to make pressure more consistent and sometimes stronger. these pumps are nice because theyre easy to modify and rebuild.
Is it just me or do the rod and crank journals look huge? Maybe its just the perspective from how small the engine is

that's not a bad thing in my book

I was a little concerned about how this motor would hold up with a tune on it but it really seems well designed. I hope to get 200k+ out of my sonic and correct me if I'm wrong but I think its possible.

My last Sonic was totalled at no fault of my own. So stop being like me and calling other people names when it might not be their fault.
edit : although that certainly looks like it was their fault.

You know the difference between my Cruze and Sonic is weird.
The Cruze feels faster in some ways, probably due to the gearing and yet I often find my self with the pedal to the floor where my Sonic is almost never floored.
Overall I think the Cruze is slower then the Sonic.
Both are stock of course.

What's the weight of the Cruze compared to the Sonic? I know the Sonic is lighter but not sure how much.You know the difference between my Cruze and Sonic is weird.

These cars are pretty light weight, which means weight ends up mattering a lot. I feel a big difference between when I'm driving alone and when I have a passenger or two.

I've noticed the same thing. Had a carfull of people and they wanted to see what it could do. I floored it and kept thinking "when's the boost gonna kick in, sh!t whats wrong with my car
". Then I thought about it and 500lbs of people will do that lolI'm curious aswell. After you said this I actually realized this might be why lugging an engine is bad, low oil psi. Before I'd never heard an adequate reason why lugging was bad, mostly wives tales type BS.
I was just thinking about this. I'm wondering if as RPM increases the vane would cause the spring to compress opening up the clearances and causing psi to drop and flow to increase?

I was looking for the weight of a basic LS and I found its 2745lbs. Found this link which has a lot of specs;
2012 Chevrolet (USA) Sonic Sedan detailed specs and performance
Does our sonics come with a heated oil pan? I just read somewhere it stated it was a option for our cars, but I can't find that article now.
