Can a big block water pump be used on a LS engine?
This adapter kit from Moroso allows the use of their big-block Chevy water pump on LS engines, providing less weight over the stock pump, more coolant flow at idle and the option to run big-block Chevy accessories. Electric water pumps are ideal for drag racing applications.
What kind of fuel pump do I need for a LS engine?
Virtually any aftermarket EFI in-tank pump that can supply the 60-psi fuel-pressure requirement is suitable. Many builders suggest the Walbro 340 in-tank pump because it holds higher pressures and has proven to be very reliable for supplying LS engines.
Is the Moroso LS engine an electric water pump?
Schroeder also points out an interesting feature of the Moroso LS engine electric water pumps. Moroso has designed adapters that allow the LS engine to utilize its big-block Chevy electric water pump. “The end result is that it eliminates the bulky LS water pump with a more compact, cost effective pump,” says Schroeder.
Which is easier to change external or in line fuel pumps?
External, or in-line pumps, are simpler to install and are usually cheaper than in-tank fuel pumps. In-line pumps are much easier to change, making roadside swaps bearable.
What kind of fuel pump does a LS1 EFI use?
This kit includes a high pressure 255lph MSD in-line pump capable of 43 gph @ 40 psi or 39 gph @ 80 psi, a filter/regulator assembly, and all necessary fittings (including fuel rail fitting and hard-to-find -6 AN female to 5/16″ hose barb fitting). Pump draws only 5.4 amps and supports up to 500 horsepower.
What kind of oil pump does an LS engine use?
Perhaps the most dramatic LS engine architecture change was away from the traditional Gen I small-block Chevy oil pump. All small- and big-block Chevys employed a simple spur gear pump driven off the camshaft.
What should idle pressure be on LS oil pump?
Despite this lower pressure, there still is sufficient oil volume to feed the bearings and energize the hydraulic roller lifters. Given this situation, excessive idle oil pressure is of minimal benefit. Idle pressures of 30 to 35 psi, or even as low as 20 psi, offer no cause for concern.
Where do inline fuel pumps need to be installed?
These are inline fuel pumps, we recommend they be installed between the factory (or another aftermarket) in-tank fuel pump, and the fuel rail. These may be installed in the fuel tank, but some custom fabrication will usually be required.
