Personally I like the look of this crate LS3 variant: http://store.chevroletperformance.co...-19244549--%3E

6.2L, 480hp, 475 ft-lbs, $8K brand new. Some googling ( Engine Weight LS3 (LS376-480) : MG Engine Swaps Forum : MG Experience Forums : The MG Experience ) says it only weighs 375lbs right out of the box. Description sounds like a nice flat torque curve too.

More realistically, though, I'll probably search for a cheap LS6 or LS7 from a wrecked vette

i would go LS3 also, LS7 is high strung cause of the bore to stroke ratio and piston sideloads. plus thin piston walls. Theirs a reason the Zr1 is based on a LS3 motor when the wanted to go F/I

Shows the oil pump location if you wanted to look at it. My car is in the states, and I, currently am not. From a glance it looks as though it would be directly behind the belt/pulley assembly, might be hard to get open; though I would think you could open it up without draining the oil, it would be pretty easy to get crap in the sump = bad.

Edit: I too am interested in how or why the oil pump gears are substandard, and what this means for the weekend warrior.

To remove the oil pump:

REMOVAL
1. Remove oil pan (upper and lower) and oil strainer. Refer to EM-77, "Exploded View".
2. Remove front timing chain case and timing chain (primary). Refer to EM-50, "Exploded View".
3. Remove oil pump assembly.

Timing chain removed. Not easy.

The gear is sintered metal (small metal pieces bonded together). This metal is suitable for lower temps but at race temps can disintegrate.

DR_ · 10-01-2012, 08:19 AM

But what is "race temps"?

Probably part of the reason for the 280F/300F engine protection.

DR_ · 10-01-2012, 10:50 AM

So at 260F temps do you think we are okay?

we cant be sure how much abuse the gear can hold

Ive got up to 145C *293F* when my VVEL decided to break down...
we now know that the oil temp on the VHR is taken right before going in the engine.
which mean there was probably a good 15-20C more which bring to 160-165C *320-329F* (having a dual oil cooler)

no matter how slow I was going to cool down,, nothing was bringing the temp down even with my oil cooler fan ON.

my guess is the oil pump is fine to that Race temp(260F* as someone said,without to much of a problem, but I would avoid revving pass 7900rpm
also having a heavier oil weight would probably help at that temp, (this is what ive been told ,,,)

ValidusVentus · 10-03-2012, 12:03 PM

So what I'm getting from this is if we keep our temps within reason there is no issue. Still my mind boggles at ever making engine oil pump gears out of such a material, sounds like metal plywood.

@Megan370Z - If yours held up, then the rest of us probably don't need to worry.

for the 95% of 370z owners I totaly agree with you.

but there is that 5% that keep pushing to the limit and ofcourse if they dont have any support mod on the oilling system ,, that might/will also happen to them

I learned a quite expensive lesson but I take it with a smile and move on with Megan Version 2.0
