Undecided four stroke turbo or build 2 smoke turbo

[sled_wrangler]

like the title says ... i have been thinking about putting a turbo on my 2010 m8 but was recently talking with a few guys and found out its going to cost more then i thought so now im thinking maybe buy the new 1100 turbo but not sure if want to deal with the weight of the four stroke

what are the pros to the four stroke and cons
prons and cons of doing a build with the m8

4 stroke is more reliable and build better torque. 2 stroke lighter and less complex. dont think you can go wrong with either.

I would do the 1100. Rode the M's for years and loved them but I like the ProClimb chassis a lot better. Better ergonomics for me and less effort to ride. But...I haven't rode the 4 stroke in the ProClimb chassis. The 1100 engines are bulletproof and can make awesome power on the cheap.

Of course the M8 is bomb proof and can handle a turbo easily. Keep in mind too, your turbo M8 wont be worth much when the time comes to sell it. Been there, done that.

On a side note, I was in almost the same predicament as you when I was looking to turbo my M8. I ended up selling my stock sled and purchasing a turbo M8 already built. Saved a ton of $ and time.

Im not an expert but from what ive heard the problem with the "stock" 1100turbo is that the turbo is pretty small and no matter what controller you;re using or exaust ext with it, 200hp is all yer gonna get out of it. 200hp isnt bad but if you want more out of it than that, you are lookin at a 6-8g turbo kit same as you would need for the 2stroke.

You would be able to get way more Hp out of the 1100 if you wanted to spend the money, and more reliable too.

The problem I have with the 1100 or any of the current 4strokes is they are still a bit too heavy of a sled for the mountains imo

Thats why I would go with the 2stroke. Like has already been said you might be better off to sell your sled and buy one already turboed. Tons of M8 turbos for sale cheap on kijji.

Buy one that's built......as stated above you will save a ton of cash. 4 stroke= reliability...2 stroke = lighter sled. There's been some good reports coming out on the "Boost-it" fuel system and if it's all true, it would be the one system I know of that's truely rider friendly. I've had a Nytro an M8 and a Pro RmK with boost and the only one that I never worried about all day long or had to p*ss around with fueling and stare at egt every second I was riding was the Yammy. A friend with TSS system(Boost-It) seems to be having really good luck here in the Flats and out west.

Chris Brown was selling his 11 Twisted Turbo M8 a little while ago. Not sure if it's still available, likely not as it was a good price, but might be worth messaging him.

If you're going to Turbo your M8, I'd do a complete engine rebuild first, once they have a bunch of miles on them I've heard that they can be a little grumpy. I have a '13 etec turbo, 1000 km and no issues but i'm also running straight av gas. As said before 4 strokes are heavier but more consistent. 2 strokes are lighter but dont have the low end a 4 would. I personally love my Etec Turbo though, and wouldnt exchange it for a 4 stroke but thats just IMO

Yeah the Boost-it controllers seem to be the best most user friendly system around forsure.

Im excited to see how these New Vi-Pecs are going to work. Vi-Pec is not just a fuel controller it is a stand alone ECM that lets you control every thing from fuel to timing. These arent some thing joe blow can just tune himself tho. You need someone who is a pretty knowledgable tuner to set it up for you. Once its setup you shouldnt have to mess with it ever again.

They are currently only available for the pro, but I think stand alone could be the future of turbo sleds.. Time will tell.

Personally I wouldn't buy a boosted 2 stroke, or even a 4 stroke without serious engine review. Boosted 4 strokes need a leak down test at bare minimum, 2 strokes could have any number of issues and should be reallly looked at critically, especially engine internals. Some work good, many don't. Was just talking to a guy who rides sicamous the other day, his buddy bought a TM8 and its been nothing but headaches and hasn't run right from day one. Couple other members here also bought pre-boosted sled and nothing but issues also. Not all like this but what are you willing to give up? The attraction is that it will be cheaper than installing it yourself and your get a turn key sled, the down side is you might wind up with a problem child that will cost you just as much in the long run. This applies to both pre-boosted 2 and 4 strokes.

On the flip side, buying a kit and installing it yourself on a 2 or 4 stroker. You know the history of the sled and what it has been through, you also get the knowledge of the kit and if something goes wrong, at least you might be able to fix it or trouble shoot a problem easier. Downside is it might take some tuning to get the kit right, which could mean your first few rides out "tweaking" etc might not be at full potential (or even half potential... LOL).

2 stroke is by far the lighter of the 2 sleds, but with the torque of the 4 strokes, I've never really been able to find the weight as noticeable. Stock to stock unboosted you can feel it, but once you add boost to the 4 stroke, its a different sled because you won't steer it with the skis, only what's left of the track on the ground.

The 4 stroke is a different animal, especially in the 1100. Its heavier for sure but will last longer. The 1100 builds peak torque for over 4000 rpm, the curve is basically flat. A re-programmed box on the 1100 will get you 240 HP on pump gas for $600. 2012-2013 1100 Turbo PROCROSS / PROCLIMB ECU Re-Mapping (MULTI-MAP) Adding some intake capacity and a few other little tweaks and upping the boost only slightly, it doesn't take much to get in the 225-250 HP range. The stock turbo only runs 9 PSI, its got some output left from what I understand. Boondocker was making use of a bigger turbo capable of up to 40 PSI, not sure you'd need anywhere near that boost though and I haven't seen a kit on their website yet. Hope that helps.

I got no experience with either 2 or 4 stroke turbos. But from what I read and heard make sure you do your home work and get someone that knows what they are doing to do the install! I think once things are all set up you will be all smiles either way you go.

this just confused me even more lol

i agree not buying a boosted sled and not knowing the history of it

i agree with building my own like you said cause i know the history of my sled

my problem is i like the trees as much as i like to climb and this is where is where my problem is ... i know you say the four stroke turbo are a different animal but how do they handle in the trees cause i dont want to just point and shoot !!!!

mind you i started off on a 04 900 1m and learned to ride a m8 totally different sleds so i think the new 1100 proclimb will just be a new learning curve just gotta harden the phuk up lol

so i guess this did help lol 1100 it is !!!!

thanks for all your help!!
