Shop around and see what you feel comfortable with. I have a CSR 35gpm unit, with a Champion 3-core radiator, and stock fiero fan.



Would you happen to have a pic of the CSR 35gpm unit installed or a part number.?

I don't remember the PN. I think it was CSR 925 or someting like that.

This is what I did on my Fiero. The water pump is installed at the front but you can istall it anywere you'd like. To avoid air pockets install it lower than the radiator like I did.
The pump is a BMW(Bosch) part number that can be found at any Advance Auto or NAPA or O'Reilys. It's been tryed on daily drivers and track BMWs. The one thing that'll you'll need is the controller for that specific pump. It's made by a company called Tecomotive in Germany. I don't even use a thermostat, it has a setting for that.

Disregard the stock water pump, I'm using the stock engine configuration. I cut the impeller off just to use it as a pulley.

Cyrus88, is that a remote water pump?
If so, where did you place it?
Did you have to modify the LT1 water pump?

Thank you for providing this option. Did you have to use a relay? Do you have the wiring diagram?

The controller comes with instructions on how to wire it and it also comes with the connector for the pump.
But to answer your question, no. It only uses a fuse for the pump but a relay for the fan control which I use the same OEM fan relay by running the signal wire from the controller to the fan relay.

Yes it's a remote WP.

I junked the stock pump and made adapters to accept 1/2-NPT. I also used a remote thermostat neck.

As you can see from my first picture, the pump is on the pass side behind the firewall and in front of the wheel well.

This pic shows the adapters and lack of stock WP.

If you can't make your own, shop for remote water pump adapters for LT-1 on the net. I remember seeing some, but can't remember where.

very clean looking.. do you have a pic of the remote thermostat neck?

Not a very good pic, but I have posted this one before somewhere on this forum:

The remote thermostat is Moroso 63426. I drilled and tapped the side for the PCM temp sensor (the one that is normally on the LT-1 water pump)

The goose neck is a CSR swivel kind.
