first of all, that first one is a .28, those are used in big block off road trucks, also, what is your price range and are you just using it for bashing or true racing on a track, the 18tz is gunna be way, way more power than you can need or use because the tc3 is so light

Cas_NitroGT

well pretty much both... I bash on the week days with my brother and a cupple friends with R40's that have the Sirio Evo3 in them but I race on the weekends for money and winning rc cars if they put them up... I'm a club racer. but need a little bit more power... I've been hearing alot of good things about the O.S. 18TZ... whats the hp range on that ?... because I know its about a 200 dollor engine...

GET THE .18TZ I HAVE IT AND IT RIPS. buuuuuut you must know how to tune it for it is a turbo motor. which tend to be a lil more finicky but i love it and am thinking putting one in my revo if i don't go big block so that shows the horsepower it has.

The .18TZ should make a little more than 1BHP (real world HP). It's advertised HP is nearly 2.2 to 2.3HP. Bear in mind that advertised HP is very different from SAE corrected real world HP.

The .18TZ produces torque and HP that rivals many smaller displaement big blocks (.21 engines). In a light vehicle, (I have one in an HPI R40), the .18TZ will literally cause all 4 wheels to drift at the instant the trigger is pulled. It will take you alot of trigger discipline to tame this and master maximizing your car's acceleration.

The Kid and I both have TZ 18's in our on-road cars, ( my RS4/2, his NTC3 Factory Team Car ). Crazy power, and holds a tune well. More power than you really need. A CV 18 may be a better choice as it's a little less powerful. We have the CV's on our RC10GT's, and they are great.

well see I was gonna put the .18TZ in my NTC3... but the thing is... would the slide carb work with the stock servo ?... because it have a rotory carb. I just wanna buy the engine and the roto start on it and break it in. and anyway how much would a break in station cost a guy ?

Rotorranch

Yeah, either the slide carb or the rotary carb will work on the NTC3. You will have to change the carb linkage around some. Refer to your instruction manual for specifics.

As stated earlier, the TZ is way more motor than needed. A CV-18 is plenty. The Kid completely shagged out a brand new set of tires in ONE TANK OF FUEL with the TZ-18.

The .18TZ also comes in a rotary carb version. I think it is the -P, I cannot remember, but check out the OS website, they will tell you the exact model that has the rotary.

Cas_NitroGT

see but the rotory carb doesn't have the SG shaft... thats the thing that worried me... so pretty much the CV 18 is the way to go ?... what hp is that ? and whats the rpm rate on it ?

hpi apollo

the 18cv-r is rated at about 1.6hp, its not a high rpm engine but it makes up for that in torque, trust me, its a very good engine, starts easy, tunes easy, reliable, and powerful
