That would be nice. It'll take some time but you'll be the first one who did it on a NTC3.

Many years back, when two speed trannys was only on the Sperents. My buddy brough the two speed tranny and converted his one speed Burns (Off road buggie) to a two speed with some custom parts and kick A##. That was the good old days. Now three speed trannys are coming out.

Status: offline 		Well once you do find out, you can email me at darkangel01_3@hotmail.com and let me know the price and everything and maybe when you buy yours you can also buy mine, I would really appreciate if you would do that for me but we can figure out the details later and thanks for everything you have done and explained me you too B.T.D.T.
thanks again i will update once the project is done.

Status: offline 		I'll let you know, and we can work something out when i buy my gears. But i'll warn you, I won't be buying mine for at least two months from now. I need to save for my engine.

Status: offline 		Good luck to both of you modifying your cars. My project for the winter hopefully is to start make a speed trap to record top speed for these cars. It should be simple, but nothing is simple if you plan on using stuff you have lying around.

Status: offline 		hmm wat kind of project are you working on I am intrested, and do you think I can go with a bigger pinion and smaller spur for my top speed because I was thinking maybe I can make a conversion for .21 engine to fit into the tc3 for example making the gas tank smaller let me know what you think of this idea if it is possible at all
thanks...................

Status: offline 		I"m building a big block rs4 for this: http://www.rccaraction.com/rc/news/car_challenge.asp

Basically i'll be running an RS4 with assorted Buy HPI and Wolf Pack Rack Radicals aluminum parts throughout the chassis of the car for stiffness. My suspension will be 1/8 scale proceed shocks with the a-arms and everything else being standard plastic shocks. I'll be running a single speed custom spur and pinion gear combo from robinson racing if it's not too expensive, haven't decided on a metal spur gear or not. Along with the custom gears, i'll also be getting robinson racing's metal ball differentials, pinion gears and brake kit. My engine will be a RB Concepts Rody C5 Circuit Team Edition. My exhaust will be a Novarossi short header with the 9886 pipe for top end power.

I should be geared to around 105-110mph. I don't plan on going to win, just wanna see if I can break 100mph.

Below is the picture of how it sits in it's current form. Except for the chassis, i'll be buying new aluminum and gears as well as replacing the brake kit with a new one. I bought it off of eBay and it wasn't up to par with what I need to go as fast as i'd like to go, so i'm replacing mostly everything throughout the car. When i'm done, it'll be as close to a brand new car as you can get.

Status: offline 		For your gearing, yes, you can run a bigger pinion than spur gear. I'll probably be running that with my car. But like i said, you'll need to have at least the pullstart engine mounts since i doubt you'll get enough clearance from the chassis.

I will warn you there is a big disadvantage with running the stock drivetrain gears and just gearing up the primary gears, you won't be able to fine tune your ratios like you would if you did custom gears all around. That's one of the dilemas I will be facing with my gearing setup, but for me, it's important to keep costs down.

As for doing a .21 conversion on a ntc3, it can be done if you can machine your own exhaust system. You'll definitely wanna run a non-pullstart engine for that. You will probably have enough clearance to run the stock tank, but if you wanna make your own, go for it. Get a OFNA SG Crank clutch nut as well as some 1/8 scale clutch shoes. Not sure if you can squeez that in the stock clutchbell, if you can't, then you'll have to machine your own clutchbell, which might require additional machining for the transmission. Also, .21 engine mounts for an RC10GT, MAY work, no guarantees, but you can try, if they don't, you'll need to machine your own. Also, one of the big things, while the stock drivetrain is pretty bulletproof for small blocks, i'll bet you'll start breaking gears with a big block conversion.

Status: offline 		hmmm I am thinking of maybe entering that challenge also but I am not sure I have enough money to buy all the custom parts I am going to need did you say you have teams sponsering you or are you paying for all the parts yourself?

Status: offline 		A little off topic, sorry. Earlier in this post, I listed my car at 60+. I was in error. When I first got my venon speed meter, I held the car and ran it at wot and it read about 45. When I took it outside and ran it, there wasn't much difference in the top speed. After changing my gears and installing the cvec pipe, I ran it again in my house and got a speed of 68. I didn't think it would be that much of a difference so I ASSUMED the car woud do about 60 on the road. I ran it today and it topped out at 54. It's still very fast for me (noob) and I didn't see any loss in acceleration. Now, I'm in search of an actual speed of 60+. Any suggestions?

Status: offline 		20blks,

I hope your not running WOT with the wheels not on the ground. You can blow your engine up by doing that. Free running the wheels at WOT can and will cause damages to your car.

To get top acceleration read the other links.
