I am looking for some suggestions for an engine swap for my Traxxas nitro rustler. Any suggestions? I want it to be fast and have some torque for wheelies. Any help is appreciated!

I’m sadly running Traxxas top fuelTrx 3.3, os .18, and dynamite 19t come to mind. What's your budget?
Tighten that slipper down, get some grippy tires, add the black spacers to the shocks yo stiff them up. After that lower the clutchbell or increase the spur tooth.
What nitro % are you running?
20% or 33%I’m sadly running Traxxas top fuel
That's not that bad where I live, I favor the 33%. I've had O'Donnell and it had alot of oil in it. My next choice is Bones Brew.I’m sadly running Traxxas top fuel
Yep. When I first got the car I immediately looked it up to see if I could get parts for itBest bang for the bug is the Dynamite .19 hands down. You could go with an OS .21 tm but that's a little overkill for that car, and a lot more expensive.
Also, FYI, while it's been around for a while, Traxxas still sells new Nitro Rustlers.
Higher nitro percent gives it more power and runs cooler. Main reason I went 33% is the hot humid florida weather.Does the 33% make your car go faster than when it is running on 20%
?
Gotcha. So it will make it faster?Higher nitro percent gives it more power and runs cooler. Main reason I went 33% is the hot humid florida weather.

I also think I’m just gonna do the Traxxas power up thingy mabob to get the Trx 3.3 because the dynamite .19T doesn’t have the best reviews for durability in the long run.
do you know of an engine that will have good bottom-end torque and not bog down? I want an engine that can go maybe 60 but also be used for racing.In very rough terms, yes. It may not raise the top speed because the engine will have a similar max RPM. It should accelerate more powerfully.
It'll produce a bit more power assuming the tune, glow plug, and compression are all compatible with a higher nitro %%. For sport engines like the .19T or 3.3, it should be fine, but "racing" engines designed for 16% fuel might need a head shim to reduce compression slightly.
I've only heard good things about the .19T, where'd you see bad reviews? From what I've read, the 3.3 has a little bit of a reputation for breaking crankshafts and/or prematurely wearing out the rear bearing, though it's still a very solid engine.

Will the .19t be more powerful than the 2.5 but not stupidly powerful where it throws drive shafts every time I drive?
You can swap a 3.3 crank into your 2.5 to gain some power. If your 2.5 is still good, it’s an economical solution.
Stroke is the same. 3.3 crank is lighter and has a bigger gas passageInteresting. I assume that increases the stroke, and therefore the displacement somewhat. I can't find bore and stroke numbers on the traxxas engines or I'd figure out by how much.
Just for the sake of discussion, could one swap a 2.5 crank into a 3.3 to derate it slightly?
