Would these engines fit on a savage 4.6 or 5.9?

If these don't work, what would be an other powerful and fast engine?
Thanks.

You do not want those, poor quality choices. Just because they are big displacement does not mean poo in relationship to power.

If you choose this one make sure you get the roto conversion for it.

Another good choice that will accept a roto backplate without a conversion kit.

These are the two strongest 200 dollar M.T. engines you can buy. They will flat out kill a 5.9 or the other two engines you listed.
Run a medium temp long plug and 30% fuel with no more than 12% oil in these engines.
You'll need one of the below pipes to be able to get a proper tune and make the engines reach their potential. There are better pipes for these engines but they require some modding. 086 style, JP-2 but they are left side pipes for truggies/buggies.

Scrogg is on point here. Those engines you listed are just "big". I don't even know if the CEN engine will fit without a special mount.

The LRP30 is a strong engine. I've seen a few vids of it in a LST2 really ripping it up.

I run the LRP28S3 in my savage and aftershock and it's a heck of an engine. So much so that I go through center axles on my savage quite frequently.

The picco 28 is a good performer as well:

One bad thing about the LRP's is that they drink the fuel like no other. Mine have both been good running and reliable engines though. The 30 wasn't out when I got mine and with the driveline wear I have running the 28's, I'm probably glad I have the 28!

run a os 30 or a axial 28rr i have them both in a savage very easy to tune and very reliable and not that pricey i buy all my parts from tower hobbies

Picco generally makes good engines. I've owned several 26 "outlaws" which is an older engine series and they have been easy to tune, dependable, and I can still get parts for them.
I've never owned the 28, but have heard nothing but good things about this engine.
The only downside that I can say about any Picco is that they have a unique (smaller) exhaust port than other manufacturers, and you need to find a gasket that seals the exhaust port to header fit or you'll have a messy ride - and also lose some efficiency. They’re not difficult to find as I’ve had luck with the stock HPI gasket, but just something to keep in mind.
There are also headers specifically sized for Picco's too.

Scrogg is on the money how the right pipe will allow you to get a proper tune and help the engines reach their potential.

I've never owned an LRP, but I seem to recall that Olds here has 4 gallons on one. Which is quite a testimony. I know that a lot of that 4 gallons is due to proper care and feeding on his part, but it takes the right materials for an engine - specifically the piston/cylinder - to have that longevity.

Since you're already in the price range with the Cen, I'll throw out my engines of choice which are 28's by Novarossi or RB (which is a essentially a custom branded Novarossi).
Novarossi offers 3, 5, and 7 port 28's and they're powerful and reliable screamers.

http://www.rbproducts.com/mainEn.php?part=Products
Amain hobbies carries both brands - http://www.amainhobbies.com/

Since both manufacturers make pull-start/roto-start and bump start models make sure you choose one of the former since bump starts don't work in a Savage.

Given everyone’s recommendations I think that you have some good engines to choose from. Have fun with whatever you choose!

I've gotten as much as 12 through an old OS 21 RG before giving it a pinch then ran another 4 through it. It still runs, but after running an LRP, I realized that it's a really weak engine for a MT.

As for the LRP's, I have about 5 gallons through the one in my aftershock and at least 3 gallons through the one in my savage. You can still feel the mechanical pinch quite a bit with the glowplug out of the 5 gallon engine.

The only issues I've had with either were the o-rings in the aftershock one drying up and causing it to tune itself lean on me and the one in the savage seems to seep a bit of fuel around the carb slide.

That RB does look nice:

Little rich for my blood though. Then again, you get what you pay for. RB's are known for lasting many many gallons and putting out some serious power and RPM's.

I should do a search on youtube and see if anyone has that engine just to hear/see what it does.

well dang well I've been rocking for awhile an fig i try something diff so i got a xxl aftershock from a buddy an he had a k4.6 he wanted to sell to so i got it i was thinking it be a fast motor but guess I'm wrong o well olny $50 more new in box so what is the fastest motor i can get for this truck I'm wanting crazy off road speed

actually the hpi k4.6 does run pretty well,i've had one and there a fairly good engine but the picco is a better motor for sure.

 

[richierich]

i have the rb 28 turbo very nice motor pricey about 500 but worth it balls to the wall

Send the K4.6 to Extreme RC Mods if it is still in GC......you'll never believe it is the same engine when he is done. Your buddies will be chasing your exhaust...
He can turn that mill into a beast.

ya your right on the money with this comment,i've watched a vid of one of his modded engines in a truggy and its doing wheelies as long as a football field,and truggies arent supposed to wheelie lol and the modded engines run smooth right from idle all the way through the RPM'S....
