The original Wireless Lego Race Car was built with the hacked motor and gearbox with axle that I took out from small toy R/C car, and modified LEGO Plates to be used as a servo mount.
Later on I designed new three new hardwares to be used with custom design LEGO vehicles or robots:
So, I no longer have to hack or modify anything any more. Now it is a lot more convenient, when I have a new custom design LEGO vehicle or robot to build, I just order the 3D printed motor housing and servo mount (since I do not own a 3D Printer!) 

Even though this was a "redux" or a rebuild of Wireless Lego Race Car, there are some changes on the parts. But the shape of the car is still the same.
I am going to show you how to build this car step by step all over again just like we tear the model apart and rebuild it.

where did you get the motor and controller? I didn't know they made those pieces!

I got the motor from e-bay.

For the Palm Arduino Plus (DIY Arduino with motor controller on the PCB) is the prototype that I designed specifically to use with LEGO components.
I got it made from third party fabricator (OSH Park, http://oshpark.com.) the EagleCAD files provided at Palm Arduino Plus here, http://www.instructables.com/id/Palm-Arduino-Plus/.

By the way, I have some extra motors that I can sell to you. Sent me Private Message.

Hmmmmmm, how much does it cost???
sath02 (author)  S.Korea12 months ago
This is my rough estimate:
LEGO components, based on LEGO's Pick-A-Brick shop (http://shop.lego.com/en-US/Pick-A-Brick-ByTheme) and BrickLink.com (http://www.bricklink.com).
The components are also mixed between the used and new from both places, and the price is for USA only. You might get it cheaper in other country.
I got it around US$ 27.00.

9g Micro servo is around US$ 6.00
2mm Shaft Adapter is US$ 3.00 from Pololu.
9V 24mm Motor is around US$ 2.00 from ebay.

3D printed servo mount is around US$ 6.00 from Shapeway.
3D printed motor housing is around US$16.00 from Shapeway.

You will also need Arduino, some where from US$5 to 25, depend on whether you are doing it yourself or you are buying the ready made.

And you will need wireless module, either Bluetooth, XBee module, or RX-XV Wifly module.
Bluetooth is from US$ 5.00 from ebay to $40.00 brand-name buletooth.
XBee modules (you probably need two, and it is around US$ 26.00 each.
If you use RN-XV WiFLY module it is around US$ 35.00.

All the price quoted above are not included Shipping and Handling.

Hope this answer your question!
