Convert carbureted pre-2010 Vector engine to fuel injection?

[melmaq]

(I've posted in the RS/RX section, but got the tip to post in the 4 stroke turbo section, so here it goes!)

I'm considering the swap from a 2005 Skidoo Renegade, 144"15"2,5" 827cc RKT (158-168hp) to a Turbo'd Vector.

The sled would be heavily modified, steering rod, REV gastank/panels/seat, 144" 2"-2,5" track and so on.

Set aside that I haven't sold my sled yet, the talk Ive been hearing about the carburated T-Vector has the "flaw" of using carbs. IE: When rough trail riding, (bad Scandinavian trails) the sled can cough "studer". And when boondocking, tilting/rolling (somewhat frequently when stuck) the sled will be hard to start.

The turbo'd Vectors that are sold here in Sweden are almost all of them MCX rear mounts, and "I've been told" that the turbo lag of a carburated sled is more noticeable that a fuel injected one.

So, MCX has ended their production of T-Vector kits, a Supercharger from MPI would be really nice, but out of the question.. .

Anyway, It can be done, but has it been done?
To convert the engine to the newer fuel delivery system?
The main assembly is 846$, but then what, will I half to change out the ECU (engine management systems unit) as well?

Are there other better alternatives to make the fuel delivery system more responsive?

I'm a completely outside my area of expertise here, ask med anything about the Rotax Series III and it's system then I'm game, here on TY Im just out of bounds.

Thanks for your input!!

846$

There is no ECU on the carbed version so you would have to obtain one to run the FI system. (If I am understanding your question correctly?)

Alright thanks Irv!
More in depth, what will that demand?

will I half to buy a complete electrical harness from a -10 model, or is it just a modular change of the wiring?

As for mechanical and other parts, what more obvious parts will I half to collect from a -10 engine type?

 

[Redbeard]

There is a module on a carb Vector that facilitates the ignition, but will not support EFI .

 

[melmaq]

Ah, ok, so I will half to replace parts of the ignition system as well?

I will do a dive in and compare part catalogs later today (it's 08:49 in the morning here in Sweden), for now I'll finish my coffee and then do some A-Class surface CAD work.

Thanks for the tip northernsledder.jk!

The fuel system is completely different, I think the head is different, the ECU would need to be changed, the ignition is different, the wiring is different, the stator may even be different.

Unfortunatly its not a bolt on system by removing carbs and swapping on throttle bodies.

I know this is a old post but I have alot of knowledge on this if your interested also I have the parts.

You will need the wiring harness, stator, all sensors from the nytro engine as well as the throttle bodies, throttle body boots, and nytro output shaft. I have most everything and will make you a smoking deal as I want it gone.

The nytro uses a pickup on the gear on the output stub shaft off the crankshaft. You will need to machine the hole and mount for this pickup. From there switch the sensors, and stator and then hook up the nytro wiring harness. if your ambition and have some mechanical ability it can be done.

I have throttle bodies, sensors, injectors, wiring harness, stator, voltage reg. I would sell everything i have for $400. You will still need a ecu and a few other small things.

If you want you could just buy a nytro block and not have to machine the vector one. Then you would need nytro pistons. Which I have those as well with rods for cheap. The block is usually about $800-1000 for a good used one.

Heey Dirk!
Thanks a lot for your answer! I've red your REV build thread hundreds of times, and It is inspiring!

the $400 price tag seems really fair and pending on a few things these coming weeks I will get back to you on that offer!
Again, thanks!

Is this the pickup needed?

And is it on these teeth, on this sprocket, the pickup will be aimed?
