I know tht wet sump holds oil and dry sump uses a oil container seperate from the engine. Dry sump supposedly pumps oil into the engine. Better for racing and roadcoarse.

But what are the physical engine diff? As in crankshaft, oil pan etc. I have a ls3 6.2 corvette tht im workin on for a buddy. We gotta install a new engine. His is dry sump setup. They are more costly than a wet sump. He doesnt do much racing anyways.

Can a wetsump be installed in its place instead of dry sump? I do my own custom tuning for codes etc. The wet sumps are alot cheaper as well. Are cranks diff for wet vs dry? Any help would be appreciated thanks.

I am sure this can be done.
My suggestion would be to post your questions in the
C6 Section of the Corvette Forum Site.
Good Luck

Looks like this may be possible. Only thing needed would be a wet sump 6.2 and install in its place. Just do away with the dry sump oil canister and lines. I think this may be the route we take.

A dry sump system should not require any crank or other major modifications. A dry sump setup is effectively bolt on....or simple bolt off. ( well maybe not simple...but certainly no mods to crank needed )

Some people above are getting confused with a semi dry sump setup as per OEM LS7

But of course it depends on exactly what you have and are working with.

* Wet sump pumps oil that drains back to the sump.
* Dry sump pumps oil, scavenges air from the crankcase like a vacuum pump, de-aerates the oil, and reduces oil temperature. It also consumes more HP to operate.

The factory engine in that car has a long crank snout to accommodate the dry sump oil pump, different engine front cover, and a different harmonic damper.

In order to convert to wet sump you will need an oil pump, LS3 crank sprocket, LS3 front cover, oil pan & windage tray, dipstick and tube. I don't think you need a crank spacer because the original damper from that car already has the extra long hub.

And any little bit of money you save converting to wet sump will be wiped out x100 when the car is devalued because of it.

Since when did an LS3 corvette have any form of dry sump ?

Surely only the LS7 had that ?

Grand Sport Corvettes had them, manual trans equipped coupes only though.

Beat me to it. Friend of mine who road races; erupted an 08 C6 from way high oil temps. Sold the roller and got a 2012 stick GS. The manual trans GS cars got hand assembled versions of the LS3 in the same facility as the LS7/9 stuff.
In addition to the longer crank snout; I thought the engine actually sits lower in the chassis for handling benefits. Not sure there’s room to just pop a standard pan on without changing mounts.

The wet sump route would have been an option. His car is a manual ls3 grand sport edition. With the dry sump package.

To keep things simple we are just gonna pull and replace with another low milage ls3 dry sump setup. I dont think the wet sump oil pan will fit in this corvette. It has pretty low suspension. We should be pulling motor next week.
