so i think i am going to build a fpp stage 2 . what do you guys think . had a 1100 cat last year with lots of problems. going the whole way pistons fuel system .Going to put 2 ply track on it, is going to be on a new 13 renegade rmotion. Does anyone have any good suggestions on other things to do to sled?

I suggest you let me ride it. LOL

I am also looking at a turbo 1200 this year. I am going with a 180 MCX kit stage 1, and if I want to do an upgrade the next year, it can be done at a reasonable price.

Good luck.

Please keep us updated.

Just FYI, to upgrade from MCX stage one to Stage two is $3755.00. 180 kit works awesome but if you think you may want more later, a lot cheaper to start with the stage 2 IMHO.

what is a better kit for stage two .mxc or fpp. i like juston he is very good to deal with .is pistons better or head shim . i no that pistons are more money butt do they last 7500 miles we no oem do . wisco in past dont .

I have heard good things about the current generation Wiseco, although no high mileage reports. I had the first version of the JE pistons and left a lot to be desired. FPP and MCX both make great kits. Pistons are ultimately the best route over a head shim as long as the pistons seal properly which the JE do not. It is my opinion based on my own trial and error, head shim is a safer bet expecially for high mileage trail sleds. Too many unknowns with pistons from their actual design, to machine shop tolerances and engine assembly. There are many here that have lots of knowledge to share so hopefully they will pass on their experiences as well but for an all out trail sled for big miles I would go with a low boost MCX or FPP kit, or a stage 2 MCX with head shim, leaving engine stock until all current generations of low compression pistons are thoroughly proven for big trail miles. If you are looking for more of a race sled and not going for big trail miles go with the Wiseco's. Once again, just my opinion, Hope this helps...

MCX .. no doubt about it.. way better design and far better expandability ... go right for the stage II MCX and call it a day

Here is a list of things absolutely needed:

Primary Clutch (PB80 works great for low boost but stage 2 and up require STM, Tapp, Polar, HRP etc.)
Secondary Helix and spring
Gear and Chain (41 tooth gear and 102 link chain for low boost, 38 tooth gear and 100 link for stage 2)
Clutch tower and engine brace (STM, Racewerx etc...)
Wideband AFR gauge (AEM,etc...)
Boost Gauge (Aem, etc...)

Here are some optional equipment:
Free flowing exhaust (Hindle is quiet, Straightline a bit louder with some drone, MBRP is load and has a lot of drone to it!)
Solid Motor Mounts (FPP...)
2 Ply Track (Not needed in my opinion unless going to a deeper lug than stock for traction, 1.375 Ice Attack works well in snow...needs traditional studs for traction on hard snow and ice)
Reinforced drive axle (Not needed in my opinion...)
Aluminum head light bracket (Powderlites, makes a clean job and eliminates the need to hack up stock air box)


As far as Turbo kits are concerned, MCX is the most user friendly. Pretty much just install and go with only clutching changes needed to reach peak rpm. FPP needs a lot of tuning time to ensure AFR's are at a safe level. All kits require Minimum 91 octane fresh fuel and when fuel is suspect either stay out of boost or keep a can of race fuel on the back to mix to ensure 91+ octane. Just for comparison, we have a 2012 XFturbo with TD exhaust and 4 stage and a MCX 180 kit on a GSX SE and the doo beats the cat on every setting except the race setting, and these findings have been validated by Doodoctor as well in case some feel that our cat is a poor performer, which it is not. I tried the 180 kit because they were on sale for $3600.00 and it is an awesome value for the dollar, only better value is the TD cat flash and exhaust. Again hope some of this info helps and others add their own list of must have parts and experiences...

No one has said anything about powder lite turbos? Ive had 3 ski-doo turbos since dec. 2008. A couple of things if you want to run more than 12 lbs. of boost with a fpp get the al. intake(Ive cracked 2 al intake in 3 years)If you race it much you do need 2 ply track.I had a 1 ply come out the back at over 100mph.And on the fpp you will be changeing the fuel settings and the fuel presuure. I have put 4000 miles on fpp kit and over 5000 miles on pl kit. Make sure you get a good cluch.After 2000 - 3000 miles most will show wear rollers-pins-weights-bushings in cover and moveable sheave. I have had pined tra-micro-belmont-polar-tapp clutchs. also have 4 friends with ski-doo turbo and they have used diff. clutchs encluding supreme tool and The best so far is HRP AND TAPP. Dont be afraid to check into powder lite turbo specialy with rapid bike race fuel control.Dollar for dollar they are hard to beat.
One thing is most of the problems people have with these turbo kits are not the fault of the kit.

This is my opinion. I would go pistons because the rings are set lower in the piston. The piston is forged not cast which is much better for turbo applications. I don't now about wiseco but I have the newest generation JAE with 4000 km. I did have it apart at 1800 km with a problem with head gasket and everything was good. I have the HRP and I am very impressed with how it is standing up. Rollers pins everything is in perfect condition. I am running the single ply cobra track which is still good but I don't race it. Go with 9 tooth drives and 24 42 gear and chain much more efficient, belt will last your 2500km with the HRP. If you go any lower then 41 tooth bottom with stock drivers you are going to have a lot of clutch heat which results in low belt life. I would build my own kit but if I were to buy a kit my choice would be MCX stage 2 but I do like FPP intercooler set up way better. That is the only thing that I am not impressed with the MCX. Good luck you will love the sled what ever kit you choose. Just a little advise keep checking everything constantly to avoid any problems you got to remember this is a major change to the intended design.

HRP - Clutch type .. JAE = JE = PISTONS

This is 100% true!!

Before anyone gets offended, this is just my opinion and what I have seen
as I have installed both the FPP and the MCX kits. I have seen both kits
get miles put on them and have seen the weak components...I say spend the
extra money now and you will NOT be disappointed on MCX, top quality!!

I put 3700 miles on my 1200 with the MCX stage 2, all done up in Cochrane
and Northern Quebec, I am not gentle on the machine and it worked flawless.

This info is getting better and better all the time guys , and appreciate your thoughts.

I have been running 2 stroke 800s pretty much for the last 5 years, fun as hell, won lots of local races, but will never replace my 1000sdi Mach. Since Doo is wanting to test my patience for a stock muscle sled, I decided this year to try a 2013 Renegade X and add some boost.

There are a few guys, and counting around NS /NB that have these kits, and also a few legit installers. I have been leaning towards MCX due to experienced installers and users, thus maybe have more help if needed, but also would expect less troubles.

I want a sled that I can run 200-300 trail miles a day, have a afternoon of drag racing 800-1320ft, but dont need to worry about having race fuel, octane boost etc to have the sled work good. Is there a kit available for my wants, or just stay with the 2 stroke and wait for my next NEW MACHZ 4 stroke from BRP.

I am looking at a kit in the $4-5K range that will give me 180+ HP and use mostly stock equipment.
