From what I've been reading, you need to run the L92 crank pully to keep VVT but the L92 water pump will not clear the DBW throttle body on the car intake manifold. Specifically, the tube comming out of the top of the water pump hits the throttle body.

To fix this, you need to use a spacer kit such as from Mast Motorsports ($200 for the spacer kit alone) along with a car style pump with the forward facing tube. Here is a recent post as an example of this setup:

but... I got to poking through the GM Performance Parts Catalog
http://www.gmperformanceparts.com/Parts/catalog.jsp
and on pg 219 it has a picture and a part number (12600767) for a L92 Water pump. The picture has the tube on the water pump facing the front of the vehicle, like the car style water pumps. So my question to the GM parts guys is the info correct? ...Does this water pump offer both the correct pully spacing for the L92 motor and have a front facing tube?

In the attached photo, you can see the normal L92 water pump with its upward pointing tube.

Another picture of the standard water pump alone... and the one that GMPP is calling the L92 pump.

Good find Dan!! I looked it up on GMPD, but it didn't provide any info other than the fact that it's a water pump & they're wanting $156 before shipping (which means it'll be $250 with shipping)...

I'll definitely be watching this thread...

PM me if you're interested.

Alocker, now I see what you did, lol. I didn't even see the spacer/adapter on there. Very clever. I've got hood clearance issues though so that wont work for me.

I wonder if I can just flip it?

I have a brand new L92 pump if anyone wants to buy it. It came with my L92 engine but I converted over to the Corvette parts. PM me if anyone is interested.

Flipping the TB over seems like an interesting solution... is there anyone who's had a problem with this?

Dan_W

Not sure if anyone has done it before... at least I havent seen anyone do it yet. The picture is of mine.

Please do chime in if you have done this.

Magnacharger has been flipping the TB's with no apparent problems.
