I've upgraded my NT-16 with the 18 size piston, sleeve, and connecting rod. (CEN Piston and Cylinder - G70344-08, CEN Connecting Rod - G70344-07) I just wanted to make this post because I've had excellent results with the modification.
From what I read before I did the modification, I was under the impression that I wouldn't really see to great of results. My particular results have been great. My truck is performing simply awesome. I'm running temps of 220 to 240 doing full speed runs, running in the grass, and just plain running it hard. I've noticed a change in power in my low, mid, and high range. I'm hitting second gear at just above half throttle! Before the mod I was running full throttle for a few seconds before second gear was kicking in. The second gear hasn't been tuned since I've upgraded my engine. Before the mod, I was really pushing my temps to try and achieve the performance I was looking for.
What i'm getting at is... TRY this upgrade! For $35.00 I'm more than happy. Now I must go play some more!!!

Very Nice! I've been wanting to convert my ATX to a .21 with the parts my friend supplies, but at with the rate it goes through gears now, I dont want to risk it.

Karl

poor judgement

just a thought karl - if ur meshing the gears well, then check that ur chassis is still nice and straight, it doesnt take much of a bend in it to make it strip the gears very easily

madmark

hey

if the chasis is bent , can u straighten it easily.just wondering

cenracer1

Unless the chassis is braced, it can bend in the back rather easily..It can be straightened out by bending carefully in the opposite direction a little at a time until back in position.... The new era roll cage will help eliminate this as well as the jt chassis...

madmark

what shell is that proline one and is it 1:10 scale or what , where would i get one

thanks madmark.

PROLINE SILVERADO




WHAT SCALE GENIUS

poor judgement

im not tellin yer.

madmark

well if ur able to get one to fit mt2

.............somehow i think i'll manage lol

What kind of plug do you use, mine use OS-8 with 20% nitro. Just run for 6 tanks, the clutch bell stripped out... over power ???

poor judgement

u mean the teeth on the pinion gear stripped? or it burnt the clutch out? if it burnt out then u may have something binding somewhere. do all ur shafts turn freely? and are ur clutch shoes ok?

i have a os 18 cvrx in mine, it just snaps and twists my driveshafts for me, which is nice.... i havent had any clutch problems, yet...

rolland

The OS 8 is kind of hot for that motor. I have done the .18 conversion and us the OS A5.
CEN also recomends a short cold plug for their motors.

Does the conversion from the NT16 to NT18 also require the new head and button from the NT18? CEN Racing posted that it was recommended in the conversion. I wanted to make sure what all is needed before placing my order with my local hobby shop.

dkf1979

I read that the new cooling head was needed because the buttons were of different size. So I ordered the cooling head listed. !QUOT!I!QUOT! couldn't figure a way to make the cooling head work. So I ended up not using it, and just reusing the original setup. It works just fine. Again, !QUOT!I!QUOT! would say it's not needed, save your money. [:@] The only thing I needed to replace was the piston, sleeve, and connecting rod. I could have probably got by with the regular connecting rod. But I didn't want to take any chances and ordered the .18 size one. It's noticeably thicker than the stock connecting rod.

poor judgement

that sucks - cen recommended the head and it doesnt fit? oh man..... who writes their posts? the company secretary?

sschuler

Anyone have a link to where I can get the piston and sleeve?

dkf1979

Go to Ehobbies.com and type in the model #'s I mentioned up top into the search bar.

cossie

if the chassis is braced it shouldnt bend in the first place lol

sschuler

I'm slow. Forgive me. ;-)

The attached picture shows how I stiffened the chassis a bit. I added a aluminmum brace between the trans mount and the throttle servo. The other mods shown are a TRX2.5 engine, LD3 pipe, and Ofna 125 CC tank. This is my first picture post so I am not sure if it will actually post without seeing it in the preview.

The larger cooling head isn't needed. My max temp on a 90 degree day was 280 and that was running flat out for the hole tank.
The purple cooling head that is usually recomended is one of the option parts for the .16 if additional cooling is needed.
I would also recomend putting in a new piston pin. The added security is worth the 2.00 or 3.00 dollars

ravmsem

how noticeable is the .16 to .18 in the low end? from take off will the mt2 stand up?

Generally no, but there is a noticable increase in torque running through grass.
It will mainly depend on the gearing and what clutch setup you are using, along with what truck you are doing the conversion in and the suspension.
Mine would do small wheelies with the stock chassis using a 12 tooth clutch bell (single speed)
and an XTM sliding clutch with Traxxas red springs on the rear and Losi silver on the front with the stock shocks and oil.
Now that I have the JT chassis it wont at all.
