View Full Version : bye bye water pump

Ready to upgrade to an electric water pump. This will be controlled by the AEM EMS. That means it can be run even after the car is shut off (and other neat options).

Without this and the A/C, the car will be running only two pulleys.

Picture is on the built motor. (Don't worry, the NST crank pulley will be transferred over :smile: )

This photo shows the block off plate but where is the (I'm assuming) remote pump?

Cali-we ran an electric water pump (from a Civic) on the Yaris. We stuck it inline in the lower radiator hose and simply disconnected the water pump pulley for dyno testing. Getting rid of accessory drive from water pump is worth a few extra horsepoweer.

Electric water pumps seem unreliable to me. It's not the pump itself but more the thermostat to engage it that scares me. It's obviously a simple way to gain a few hp though.

The remote pump isn't installed yet, since the motor is sitting on a stand waiting our swap. Hadn't thought of using a Civic pump, I was going to buy a new aftermarket one. Thanks for yet another good idea, Richard!

Electric pump setups are very reliable (e.g., Civics have them) - this one will be controlled by the AEM as my first post mentioned. Mechanical pumps fail, too - as do thermostats. Just have to watch the temp, another good reason to have real gauges on these project cars!

Looking good so far Garm. Where did you get the block off plate?

Art had it made, or made it himself -- he sent me the pic from his cell yesterday. :smile:

I wouldn't mind a spacer for the oil pan, for a little more capacity.....hint hint... NST...hint hint.... :wink:

I love it Garm , go bigg or go home . Damn your car is gonna be a freakin' track(drag/road) monster after the engine swap/Aem ems is done/tuned, Omfg !

Let's do it!!! You know how to find me to get the ball rolling :biggrin:

i know more oil capacity for a stock internal n/a car may not be necessary, but if the price is right..ill support nst and micro image! ;)

For open tracking the car is probably needs something extra. I have not seen the oil pan and windage tray, but I doubt it was designed with sustained high g turns in mind.

Garm, to be honest you should probably just do an Accusump setup to protect yourself from oil starvation. It is only a couple hundred bucks.

i do plan on autocrossing this car as well as taking it on a few road courses. maybe a pan to hold an extra quart would be sufficient? would cooling fins on the pan work to keep the temps down as well?

Adding some extra oil could be a good idea. Really you need someone with their oil pan off to see how much extra you can actually put in. Someone like Garm who has their engine out already :)

It is kind of a mystery as to how much to add. As a guess I would say 1 quart would be too much. That is over 25% of the total capacity.
I have no data to make a concrete statement though.

Again, I'm not sure on how hot the oil runs in this car. I don't have a gauge in mine. I'm sure a finned pan would help a bit.

well i believe we need to conduct some studies. to get the temp would a filter sandwich adapter and gauge be accurate enough to read temps?

At both of my trackdays I never saw the oil temp above 109 C. I run the oil level about a half qt. low (about halfway or a little lower on the dipstick) and never saw any abnormal oil press. fluctuations (i.e. pressure changes not consistant with rpm).

With a higher output engine (boosted) I could see the need for an oil cooler or a finned pan, but for an N/A application of the 1NZ I don't think it's really needed.

I think a pan rail spacer would be cool to run if we were able to drop the pickup the same amount, and then run about the same amount of oil (or maybe a half qt. more). It would reduce windage, and maybe allow the oil to "calm down" a bit more before getting sent back through the engine. With the way the sump of the engine is set up, I feel pretty confident that the 1NZ with stock oil capacity can handle any kind of lateral G you can throw at it (I had absolutely no problems at the Streets of Willow).


Cali....that water pump is the nuts! I'd be really interested in doing the same thing on mine.....and removing the A/C is getting more and more tempting every time you mention it! Great work, and I can't wait to see this thing on the street!

Mike....I'm running an ARK Design MFD with the oil press. and temp. sensors mounted to a glowshift sandwich plate. I have not had any leaks at all with this setup.

Thanks, I will look into that!

Oil cooler will be added when we do our install.

You can also pressureize the oiling system before you start the car.

Good to know. 109C is about 230F which is a little warm, but still ok. Be aware, as you get faster, you will have more issues with heat.
If you get R compounds you could start to have oil starvation issues on sustained high G corners. Many cars have this problem on sticky tires. On street tires you may never have an issue.

I definately would not run the oil lower than full at the track. The potential problems of running less oil and having starvation issues far outweigh the possible slight power losses to windage when running full or slightly overfilled.

Water temp, oil temp and oil pressure is what you will want. Boost is not a big deal with a supercharger, but if you have the coin and space, go ahead.

Good choice on the electric water pump and the AEM EMS (Two steps are a thing of beauty). If you haven't already picked up a pump yet then I would suggest and EMP unit, they're very well built. I was helping a friend out on his BMW 330ci build and I couldn't get over the quality of it. Here's a picture:

LtNoogie, I'm running oil temp. and press. with the ARK design MFD, and water temp, ignition, and inlet air temp with the scangauge. I also have a tach mounted on the A pillar.

Thanks. Any pictures of the gauge layout would be appreciated. You could even start a new thread for gauge layout.

I might do that....I'm in the end stages of getting a pretty trick install finished for the MFD, and there will most def. be a thread when it's ready to go.
