    Oh man am I ever interested. I have found an easy way to resize my pictures is to just email them to myself and then I can select a smaller size. I am not really familiar with the 660 turbo sled engine but I know lots of guys that run it! I live in snowmobile country. Very interested!! Could you post some info on the work you had to put into it?

    The only issue I can think of for me anyways is that I have a 93 with the F6A engine and the 2002 has a K6A. Don't know if those two blocks are the same.

    The process started because of an air filter gasket fail on the first engine that sucked so much dirt in that it destroyed the top end... valves and head .The truck is a 2002 and the engine is a K6A Suzuki. Arctic Cat uses the K6A in their touring sleds. I am not sure if the non turbo sled uses the same engine. I bought a 2004 touring turbo that was totaled for a motor swap. The engine block is the same with just one mod we had to make.We had to machine a plug for the bottom of the block so the stock oil pan would work it was about a 2 inch round piece of aluminum that we press fitted and locktighted in . The transfer involved changing the front cover, oil pan,intake manifold,valve covers.Might have been some other things. The engine then bolts right up to the mounts and the transmission. It is not a dry sump oil engine like some say. The tapered adapter that the clutch bolts to comes off the crankshaft and then the flywheel with the starter ring gear from the old engine bolts to the crankshaft. That's all the easy part . It looks and fits exactly like the old engine. Hard to believe but true ! Now the hard part. Hadn't planned on the turbo but well........to much power to pass up. I mounted the turbo on the side of the transfer case did the pipe and hose routing. Added the heavy duty double element air cleaner to feed it behind to cab. Also built a box that brings air from the top of the cab. That box continues under the truck box and the intercooler is mounted to the front side and a continuous radiator fan to the backside. Then the complete snowmobile wiring harness was neededand the ECU for the correct mapping and all the extra wires for the turbo controll and waste gate. That was the hard part.... married the two harnesses together in several areas .Even needed the sleds speedo gauge in the cab as the main gauge. It was a fun project once I decided to add the turbo. Makes a completely different truck out of it especially on tires. It is wild !!. We have run it for about 3 yrs with no major problems .
    Still trying to get this pic posting figured out.

    Well that is awesome! So you are running your stock intake, valve covers, manifold etc? Did the engine go in on the same extreme slant as stock? I assume so if it bolted in. I am sure this is just the start of the questions! There will be a lot of interest. The extra power would be great for my tracks!

    Bolts in the same slanted on the side.. Same engine you had before

    I do use the Arctic Cat 40 dollar per gallon synthetic oil now.. I would recommend that.

    Finally got it figured out. Hope the pics help you guys with your dream !

    Oh it is really nice to hear someone actually did it. I know Kccats has been interested. Now to figure out if it can be done in an older model like mine. Are you using the factory Suzuki fuel pump?
     
  14. Kent

    Kent Member

    Engine is fuel injected so I am using the fuel pump in the tank of the truck.. did some marrying of wires between the truck harness and the sled harness

    Sounds great!
    But I am concerned with mine not being efi?
    Do you have any idea what the differences are between the F6a and the K6a motors?

    I do not.

    Very cool! Thanks for taking the time to make the photos work. Looks like quite the ice fishing rig!

    Thanks ...used a tracked atv last year . Hope this worked even better

    I used to use my Brute to plow with, now that I have plowed with my Suzuki, I'll never go back!

    OK on with the search!
    I may start my own build thread?
    I have bought a pair of Arctic Cat exhaust manifolds!
    A Non Turbo Header! And the turbo cast iron!

    So are you attempting to just put a Arctic Cat head on an existing engine?
    If you do create another thread can you post a link to it in this one?
    Good luck!

    A few things to consider when you do the build. The turbo Arctic Cat engine uses a forged steel crank the original truck engine is a cast iron crank . Forged steel flexes with the extra pressure from the turbo. The turbo pistons are low compression vs the trucks came with a high compression piston. The wrist pins are also larger on the turbo engine. The oil pump that is in the front cover is 25 % larger that the stock truck oil pump, this may be needed to supply the extra needed oil for the turbo bearings and the extra stress on the crank.
    These are just a few a the differences in the two engines that I know of. I am not sure if it makes a huge difference in doing a turbo add on but wanted to share anyway.
    Good luck

    Well the header doesn't look it will fit.
    I think I will be using the Turbo manifold!
    It is cast iron and very small, I believe I can just make a flange and weld a 2" 90 to it?
     
  26. Oh my goodness, I've been on this forum for close to two years and I don't know how I missed this amazing thread. OMG Kent you truly are a blessing, thank you so much for your info....... And your pics of the most beautiful Carry I've ever seen, wow she is a work of art, amazing job brother. I'm so happy because my f6a engine in my 99 efi Carry has been having some problems due to neglect...not on my part! But I've been in the works (saving up) to do a full rebuild and some day put a turbo charger on er... Thanks to you, my to do list has just been modified:) this is amazing! I read and reread this hole thread and my heart is still racing. I know this is a few years old but Kent if your still around could you please tell me how the transmission and running gear (differentials) held up to all this new found power? Please. Oh and I'm, in no way, a sled head. I know little about them but for the 660ac motors, do the sleds have to be within a certain year radios to match up properly, or are they all compatible?
     
  27. Ouch, heart break:( I jumped the gun! I didn't realize that Kent's truck and mine had different motors. F6A vs k6a. Does anyone know if the transmissions are the same, same mounts, same bolt pattern?

    The Carry F6A came in a turbo offering starting in 1996. They are rare but Yokohama motors had new OEM turbo exhaust manifolds. You could blow through turbo one pretty easy using a modified street bike carb..

    If you have a '99, then you really do have the K6A that most T660's had. I know sleds were built with the F6A but not many

    Cat uses the K6a motor as well
    But it uses different intake and exhaust manifolds.
     
  30. I have a 99 db52t, Wikipedia tells me that they didn't switch to the k6a until 2001 and that I have a modernized f6a engine. I know there's a world of difference in speed and power between mine and my buddies who has a 92 carry which has a f6a engine also but I assumed that had to do with intakes, efi vs carbureted etc. Matt167 are you assuming that I'd have the k6a or do you know this. I'm not saying that to be sound ignorent, I just don't wanna jump the gun lol I can go to the province next to mine, maybe a 4-5 hour drive and pick up a t660 ac turbo for $2000. I would have left by now if I knew I had the k6a engine in mine but I still believe it's a f6a, I wish it weren't and I hope I'm wrong. But even so, wouldn't the two engines still use the same block?
