i have finaly saved up enough money to get a new engine... i want to get a brand name one like OS or hpi or some other brand... i dont want a SH... no offence...

i have a $150 spending budget... witch one do you think i should get?

os cvrx but the sh is a nice engine and for the money you cant beat it.

Well for me i like the SH.... its a nice motor...
the Infinity is also a sweet motor.......
my buddy has a OS and its almost the same as the SH...
me i would go for the SH... thats just me.....

UH, get what ed says.

ok then.... i will see if my bud rob has one in-stock...

and how mutch more power does the sh 18 make compared to the vx-18?

alot, the vx is a 2 port engine, the sh is a 3 port engine.

how about a go engine?

ooh kool... i just talked to Rob and he said that he does not have any sh-18's instock so i will just get the os engine beocuse i found it on the SlapMaFro store for $90 and it was onsale and the shiping is $9 so i will go with the Os one thow... is there anything i need to get with the engine... like shafe extender, new header, stuff like that?

hear is the [link=http://www.smfstore.com/product_info.php?cPath=196_195&products_id=879]engine.[/link]

so is there anything i need to get with it?

and i will be geting a new heder so i dont need that...

you will need a new flywheel unless you use the one you have. not sure if it fits or not, but new engines dont come with one of those, or the engine mounts if they are needed on that engine. basically all it will come with is the pull start and carb.

oh and it looks like you need a different engine that is the non-pullstart engine, unless you have a roto start or bump box that will fit.

This is the engine you need. the cvrX

ya the x has a pullstart and the normal does not... i have a hpi rotostart for the vx-18 and will that one fit? and i will get a 3 or 4 shooe flywheel... for racing...

not sure but i think the engine you have listed will only work with a starter box. you will have to wait for one of the pros to answer.

if it does then i will go to my lhs and get them to get me a new backplate...

no the vx backplate will not work, you need the os setup.

eddie i know that they are 2 compleatily difrent engines! i was talking about the rotostart adapter (and it is the hpi brand) )(Part #87121) and i will go to my LHS and get them to take a look at it and see if they have a backplate to fit...

do you like the rotostart that much more then pull start? i would get the cvrx and then change out the back plate later. then you will have 2 ways of starting it incase your rotostart ever breaks.

my hobby shop here has the cvrx for $95.

the hpi starter wand would work on the os rotostart backplate but the backplate would not work on the os.

I'm gonna replace my sh engine and have been talking about it in some other forums. Right now I'm trying to decide between the sh.18, the os.18, and the lrp z.18. They all seem like good engines I think the lrp might have the most power but do any of you guys have any insight on what one might be best? 1/10 mamba/tsunami is what its going in and it has the .18vx now. I need more power lol.

well, weather its himoto or the other company, they both have engine replacement programs. The sh.18 has alot more power than the vx. The os cvrx has great power and is pretty much a direct replacement like the sh but will cost more money. I dont know about the lrp since i have never owned one, i like the power and ease of tuning with the cvrx for sure or any os engine but i have had no problems with the sh.18 either and they have plenty of power.

Is the OS much more power than the sh? They must both be good upgrades from the vx right?

Yes they are both upgrades, The SH side exhaust is just slightly less power than the CVR (both .18's) I'm mostly a rear exhaust guy and the .18's accross the board are the same with the exception of the SH .18 Pro and the OS .18 TZ, the TZ still has the edge over the Pro but the Pro breaks less parts from shear power [&o]
