Turblown Engineering's Electric Water Pump( EWP ) kit is a complete bolt on system designed to eliminate the OEM belt driven water pump. Traditionally an electric water pump upgrade yields between 1 to 2 percent more rwhp by reducing parasitic drag on the engine. The OEM belt driven pump requires power to drive it; removing this " frees" up more hp. More importantly an EWP upgrade upgrades the reliability of your cooling system:

Removal of the mechanical thermostat that is prone to failure
No more cavitation like the OEM water pump
No more belt slippage when removing the air pump which is commonly found when not using an idler pulley( even if you have larger diameter alternator and water pump pulleys- the belt will still slip, or even worst you have it torque so tight it will wear out the front main bearing, and alternator bearings)
Ability to control pump flow based on coolant temperature while engine is running, and post shutdown
LCD controller allows cockpit access to coolant temperature and Alarms


Turblown offers two different versions of this system; Street or Race

The Street kit uses the OEM FD3S waterpump housing. This does not require an alternator relocation bracket, and the loss of either the a/c or p/s. It also retains all the OEM water connections( throttle body coolant, turbo cooling lines, heater core lines, radiator hose positions). This system can be used on the track, and only differs in ease of installation, cost, and loss of oem functions.

The Race kit is more intense, and not yet finished. It mainly differs by requiring an included alternator relocation bracket( with the loss of either A/C or P/S mandatory). A supplied billet water pump housing that replaced the OEM unit completely. This billet unit includes a pressure cap assembly, and ports for heater core/turbo cooling lines, AST etc. It also moves the EWP pump up closer to the engine for aesthetic reasons. Again there is no difference in cooling performance between the two versions.

Both kits include the Davies Craig EWP 150 Alloy pump, LCD controller kit( clamps, wiring etc) & new Gates Alternator Belt if chosen as a full kit.
Street kit includes an adjustable bypass block off that also houses an included thermostat seal. Please note OEM thermostat is removed on both kits. Thermostat bypass IS required when not using a thermostat!
Optional SS allen head bolt kit for improved aesthetics.

I have just sent two units out for installation photos and video etc. Please note the install photo is of the preliminary race version.

Noone from turblown answer my questions

 

1. The post you replied to is from 6 years ago and is no longer directly applicable now in that particular regard to some of the details.

2. If you click the link at the end of the post it still takes you to the order page for what they currently offer for it on their website. Which what they offer now is described in detail there.

3. I saw a recent message from them (maybe on their blog or instagram page) that they’re swamped with a record volume of turbo orders and to expect some delay in response since they’re super busy fulfilling backorders. So you’re likely going to need to be patient.

best wishes otherwise ...

I ordered the ewp kit yesterday anyway. And still no one replyng me. Lol.
nevermind as long as their suply a good complete kit. I can do it

 

you should have received an invoice or acknowledgment email with an order number then; did you try replying to that with your question(s)?

usually worked for me in the past, but they weren’t as buried then. Having bought parts internationally and wanting to be certain, I get where you’re coming from.

You've already gone agro on one vendor because they didn't get back to you fast enough. Might want to pump the brakes.
