Engine Swap?
I have an old Traxxas nitro street and I am trying to make a drag car out of it, and I was wondering is there a way I could put a TRX 3.3 engine in it? It has a TRX .15 in it at the moment but I want something faster.
Thanks, Chris

RE: Engine Swap?
I don't know much about that car or those engines but get a spec sheet of each engine and compare the specs and see if it's possible to even fit the bigger engine in there. Is it a 1/10? Is that what people use to make drag cars? I would think a longer chassis would be in order for that application.

RE: Engine Swap?
I would assume you would have to probably replace gears if you're putting a higher power motor in it. So I would look into whatever aluminum gears you can get on top of specs on the motors so you can compare them. Should be interesting if you can do it and I bet it would scream.

RE: Engine Swap?
I just went down to my LHS and they said it would fit right in. I would just have to change the throttle linkage for the new slide carb. He said I could trade in my TRX .15 and get a TRX 3.3 for $115 or the TRX 2.5R for $85

RE: Engine Swap?
Slap a supercharger on that 3.3, 10% power boost. And they REALLY look the part !
l love em, people swear there rubbish, [ most of which have never used / owned one ] but if you buy one, and use it, you will find a supercharger can bring to life a dead engine ! Like i did.
And new engines, well it'll turn the TRX 3.3 into an OS 3.4 instantly ! The OS 3.4 has almost double the power of the TRX factory engine .
Mine was on a truggy. You dont want to flip the machine with a supercharger on it, trust me !!! mess.
For straight line speed, for turning heads, it blows alloy for bling ! And the SOUND , if you like nitro for the sound, THIS IS FOR YOU !
Before a stupid debate starts, based of the fact they cannot compress the air and therefore are rendered useless, is false.
They work through superior scavenging. ie, clearing of the cylinder. And the ydo give 10% power boost.
There about 170$ bucks though.
But its all about power and noise ! Not money ! Thats drag racing !

RE: Engine Swap?
Towerhobbies has superchargers and turbo chargers for most traxxas motors. They are rather expensive though, like $130 or something like that. At that point you may be better trying to shove a big block in there.

RE: Engine Swap?
Don't spend the money for a supercharger (assuming they work, which is another debate all together) and then put it on a crappy TRX engine. for $179.00 you can get an OS 18TZ which has much more power than the TRX 3.3 is much easier to tune and will last longer. It will bolt right in for the most part.

RE: Engine Swap?
i agree i have a friend who has had a stampeede for over 5 years and the engine starts right up. every part on it is original, even engine parts. it has an electric start too which is nice, but the engine is starting to get sluggish and its as slow as a turtle and barly accelerates

RE: Engine Swap?
People people people, what is drag racing, NOISE AND BLING AND SPEED, get a big block then, and super charge it.
There is no debate.THEY WORK.Absolute fact. Not by compressing the cylinders air, as mostpeople missunderstand, but by scavenging, superior !
It will absolutely make any engine go faster, and stronger. Around 10% usually.`You can get gains of 30% with the right induction fan replacement and tuned exhaust .
Anyways its a blingy thing, for those who love the noise, little extra power, but they are dear, never said they were not.
Every nitro driver that ever saw mine, turned there head, EVERY one of em.
The little Inferno was a rocket !
Mine was on a 4.6cc engine.
Mine got destroyed in a roll over crash, another bad point about em.
But l cannot say it sucked, it rocked.
lm now looking at the induction units that bolt onto the HPI baja , with the CY 26cc engine.
Should be interesting, from what l read they work well too.
All the nitro turbo engines l ever used, seemed to be crap.The turbo doesnt actually work.And how can it !
The superchargers however, are just a blower fan, it cannot, not work ! hahaha
PS. forgot, you all should hear a supercharger on a nitro, at TOPrev screaming past, all you nitro drivers that always argue, love the smell and sound, just dont know what your missing !
Beware , conrods in danger if you put one on a TRX 3.3 !

I've never seen any difinitive proof (other than talk) that they actually add power to a nitro 2 stroke. I'm open to the possibility, but throw me a bone here.

RE: Engine Swap?
I swapped out the Idler and planetary gears will Traxxas Rustler VXL tranny gears. They are 48P gears. I also made the planetary gear posi by putting epoxy inside.

Any dyno numbers to back these percentages (comparison of power before and after supercharger installation), or should I just assume they were pulled out of the air?

Real world experience.
They have been dyno'ed and yes they can pull up to 30% with the right fan, standard its 10% ,do your own research, there a few years old, l aint spending 7 hours finding old posts for the details, just buy one. They work.
Have you actually seen any real proof of ANY nitro engines ? Is that common ? NO.
Traxxas claim over 1 HP from the TRX, like to see you proove that, ppfftt.....Cen recon they get 4HP out of one of there engines...bs.......PROOF and claims are different l agree, but dun get niggly with me over superchargers, had this debate a few yaers ago, is why l bought one, after arguing they cannot work, i was forced to EATMYOWNWORDS.
So go eat yours.
Or buy one and we will debate it if yours doesnt work , ok ?
Before that, you have no argument saying, what you did.
But by all means look into them, there not worth the power per buck, but they are bling noise and look the part.
The numbers were originally posted on there sight. RB.
Independant testers gained far more with exhaust modifications and induction fan changes.
If you understand how a nitro engine works, it becomes common sence that they do actually work.
The debate is how much boost they can give.
At 10% on a nitro engine that revs to 30 or 40 thousand RPM, if you cant figure that the scavenging is going to increase air flow, and lubrication, your missing a few l recon.
They can be fiddly at first to tune.

Do they make an aftermarket exhaust for this engine, because the stock exhaust is not good enough?

For that motor, you could always buy a curved header and install a tuned pipe. I think associated makes tuned pipes for small block engines.

Got any vids?
Also, please to be providing proof of the 10% gain? Since...like..you can have a 300% gain by putting in a Picco P7R...for only another $100...so why supercharge it?
