Waterpump interchangeability
Hey guys,
I've got a 6.0 LS2 out of a GTO that I'm swapping into a car it doesn't belong in (Nissan 240sx).
Short of it is that I don't have enough room to put a shroud and low-pro fans behind my larger radiator with the GTO specific LS2 water pump on the car.
I'm looking at notching my radiator support and angling the radiator forward, but I also wanted to know if anyone has used another water pump with a shallower pulley successfully.
Here's a shot of what I'm working with currently.
I found several threads that say that you can't use the Corvette LS2 pump because there is difference in the offset of the pulleys, but I haven't been able to find any other information on this forum or ls2.com.
Thanks.
Thanks.
Go to the auto parts store and buy a LS3 pump (or if someone you know has one), but make sure you can return it for a refund if the belt rides too far out (you'll need the thermostat housing too).
Alternatively you could swap to a Corvette accessory drive including the crank pulley which would pull the accessories in even closer. Pretty much all vintages of Corvette drives (LS1-LS3) would do this.
