hello has anyone upgraded their nx-15 engine to the turbo 25? if so how much faster is the car? has any one changed the pipe on their ct5 to the g70352 pipe? let me know how much faster the car gets and if anyone has done these upgrades.

nobody knows the answer? or they haven't upgraded to the turbo engine?

Hey Chris,

I know I haven't, I don't even own a CT5 but I'm sure if someone has they'll post something for ya. Is the NX-15 not enough motor for you?

sorry idk.

Just picked up a CT5, havent even broken it in yet

There is a thread on here somewhere though, where someone put a .28 in a CT5
Pretty cool and FAST

hello guy's the nx-15 is not doing the 73 out of the box ill tell you that much. just ran ten tanks in mine and its not a powerful engine im going to upgrade to a O.S. .12tz turbo or a .12 turbo novarrosi sorry for the bad new thank for reading.

did you change belts? the ct5 comes with two different belts. if you did how much faster was it? how did you test the speed?

no i did not change the belt. I dont think the belt is going to make it faster.

the speed come from the gears or the engine not the belt.

but there are gears that came with the belt also. i think if the gears are smaller then the ones on the ct5 now it will be faster

For the CT5 the belts do affect the speed. Just not in a direct way. The pulleys are to be changed when you change the belts. The optional pulley set in the box offers increased top speed at the expense of acceleration. (gears the car taller which more top speed). The pulleys change the overall gear ratio, the belts are just a way of transferring the power like the universals on a shaft driven car.

The stock belts and pulleys gear the car lower ( ie more acceleration). The optional belts in the car will fit the stock pulleys, but they will skip and you will end up with a car that doesn't go...

As for the turbo 2.5, unfortunately that motor is now discontinued. Some motors you can use are the Novarossi CX15 (this is a big block .15). The big block .15s were the motors meant for the original 1/10 scale on road cars, such as the serpents, piccos, and bmts, if anybody else recalls these cars.

You can also pick up the optional CEN Engine mounts meant for standard .12-.18 engines and you could fit an OS .18 TZ rear exhaust engine or any of the other small block .12-.18s for an upgrade.

s5lin I have tried a LRP Spec3 engine on my CT5 but was unable to use the .12 engine mounts because the engine mounts screws would not go pass the engine case, can you tell me what .12 engines worked without any modifcations??

You need the cen CT4-R ones, they are also option ones for the CT-5. Let me get the part number for you. It is CTS-09



They are sliding mounts so you have a little more room to work with to fit different engines.

Yep those are the ones I am trying to use but the big screws are not going through the engine holes, causing them to stick against the crank case.

I am trying to put the engine on a CT4-R

Bounty,

Usually the allen screws that go through the engine mount are 3mm screws. Are you sure you didn't get a 3.5mm screw? (GST engine mount uses this size screw and a few other 1/8th scales do too).

If it is a 3mm screw, what I have done in the past, was I carefully enlarged the crankcase mounting holes with a drill press to 3mm to clear the screw properly. I had to do this to one of my piccos before.

Most engines have the same size clearance holes cut out for the engine mounts, but sometimes, some are a little tighter.

Ok thank you for your assistance

but can you give me the lenghts of each screws, and which goes where ?? I think I may have gotten some screws mixed up

What sizes going directly into the engine attaching it to the mount, and what is the size of the remaining 4 screws ??

I am not seeing any 3mm screws
