it broke in an hour

I got this motor on Christmas last year and put it in my lancer EVO, it ran very good for a while until i put a 4 wheel upgrade a few months later and i think that and the batteries i used kind of fried the motor and did not run as fast as it used to, and yes the rechargeable s were at full charge, but besides that VERY good product

This product is great. My camaro can get going so fast! You might read other reviews that say how bad it is, but this product is truly worth the money!

this was my worst experence with radio shack ever. the motor did not work at all an the shaft coming out of the motor was to big for the pinion gear to fit on!

this upgrade is great. I used it in my car and it has the best performence. just make sure you use the original(stock)second gear,the big gear.

Works great. What i did is i used the same motor that i had and used the gears that came with the stage 2 motor, that way i'll waste the stage 1 engine, before the stage 2 engine. Very durable, and very cuztomzable.

this engine is the best when you but the all wheel drive it makes it go as fast as it was

The torque gears really speeds your car up but the gears for speed are as slow as the stock engine. I dont understand why people use the speed gears when the tourque gears are faster. I also dont understand why people on [@] say that the torque gears are slower and the speed gears are faster. I think they got confesed or something.

it makes ur xmod go really fast but don't use 12:23 cuz it can only make your car move fast off the ground but can't really pull its weight on the ground what a great product

This is great for the xmods F-150 u get great speed and it is still easy to handle.It is very easy to instal. I have rearended walls and the engine still hasn't broken down.

this motor is awsome! the only problem I has is if you don't completly disconect it by dosconecting the wires from the car you will break the wires of the motor eventualy. I advise that you do this it takes a little longer but you won't have to buy sauder and a sauder iron to put it back together or buy a new motor.

I just got this motor, and man does it fly! The only problem is it cracked the rear driveline case on my ford f-150, because i crashed it at over 15 MPH! I love this motor. get it

deffinitly makes a difference in performance!

I just put it on today and I could already tell a difference in speed & torque, Keep it Up and you should be fine

it was pretty easy to install, and once it was installed it flew(off a ramp <=0 it made me crash a lil though because i was in an enclosed area and i wasnt used to soo much speed " U

WOW, Makes your car have soooo much tuorque and if you have all wheel drive perfect for drifting.

its realllyyy goood for a fast car GET THIS!!!

this upgrade is the next bast thing to add to your x mod. it puts some serious speed on the car. if you like drifting this is perfect for you. your x mod is going so fast that when you turn it slides so fast that it drifts perfectly!

It is a really good motor !had it cut the wires a little ad the red wire came off and almost blew up the engine but over all it is the best out there!

it was hard to turn.Then i finally found a way to drift without the drifting wheels.

yo man this is my first upgrade and i speech less now my friends dont want to lose there cars

Fast Fast Fast

takes car to the EXTREME!!!

Teh best upgrade that there is for the evolution series.

this product is great it makes my xmod go 20+ but you need all wheel drive kit too.

this thing makes it go fast!!!!!!!!!!!!

This is awesome, though I wish they sold the stage three this is great for driving fast or offroad

this upgrade makes your car fly or be really strong and unlike the classic cars the wires dont come out

This upgrade is best for your car (faster with all wheel drive)

MAKES YOUR CAR GO SO FAST!!!!!!!

It made my evo go twice as fast it is the best upgrade you can get

This motor is so worth buying it will make your car go all the faster you need it to go and its not hard to install its a great deal.

having the gear ratios is nice but the lack of low end torque in the stage to motor wasnt impressive. its a blast to expirement with this kit however

Nice motor package. Great for anyone who wants a ton of extra speed- plus it gives you all the supplies you need if you get another motor- but it won't get your Xmod to 20 mph.

it was pretty hard to install but after u installed it ur car would go 20+ mph
