I thinking about to use an electric water pump on my lm7. Its in my car that I only use on summer for fun. Will an elektronic waterpump be a good choice?

 

Depends, I think I would probably save my money for other things, but if you have money burning a hole in your pocket, then why not?

I actually prefer the reliability of a stock pump too.

 

The reason is that Im change to ls1 intake and can't use std lm7 pump.

 

I see. Well, I think a meziere electric pump is about USD$475. I would rather spend money on a used LS6 intake and buy a stock pump for 100 USD (not sure on price in sweden).

A used LS6 intake and regular water pump would probably be around the same price as the electric pump, and would be better gains in HP.

 

I need to use ls1 intake because I need to keep the egr.

 

I see, I guess they are very strict on emissions where you live. Do you think they would actually check for the EGR valve?

If they would, go for the water pump.
