Engine Swap Thread

Recommended Posts

Hey Everyone, I’ve created a few other threads and a bit disappointed at the limited responses the forums seem to get. So rather than asking about an engine swap i’d like to share some information with others here in an effort to generate some discussion!

So i’ve done much research on engine swaps for my 800cc buggy, and my ideal swap would be a suzuki swift gti engine, however they seem to be rare and very expensive if you can ever locate one. The only ones i’ve seen are going for $3500+ which is completely rediculaous becuase the purpose of an engine swap should be to get an inexpensive engine that parts are available for, the suzuki swift is neither.

So in my research, i’m specifically looking for a naturally aspirated lightweight aluminum engine that produces “acceptable” power. Far as I can tell such a thing rarely exists in the US, which is probably why the G13b engines are so redicualously overpriced.

What I have found, and present to you is a  Mitsubishi Mirage 1.2L It’s an all aluminium, lightweight 3 cylinder NA engine that’s producing 74HP and 74ft lbs torque. Not crazy power numbers I know, BUT for an NA 170lb readily available, AND cheap engine those are not bad in its stock form. Certainly those of you looking to get a little crazier than I can drop a turbo in and up those base numbers. 

Far as I can tell in my research No one has done this engine swap to date, so I suppose I will have to go fist... I am not quite ready to take on a project of this magnitude but will likely make this my winter/spring project and hope to have it completed by early/late spring next year.

I will of course document the install and process once it gets under way. In the meantime please feel free to use this thread to discuss other possible engine swap projects or ideas for such! I love me some buggy action and can’t wait to get this swap underway.

Small and powerful?  Kinda spendy but why not drop a KTM 1290 v twin in it?  Will be easier to find parts than a gti lump, water cooled, 100+ HP, chain drive, 6-speed, what more could ya want?  Gonna be spendy though, around 3-4K for a wrecker.  Any old street bike twin may be good candidate,  but many are $$$ and hard to find parts like the gti.

How would you hook up the independent rear suspension, just got a 07 joyner sand viper 1100cc dont know if the motor is good, missing the tranny. Was thinking of a engine, tranny swap with a Geo metro. Never had a buggy b4. So all will be new to me!

The geo is not a bad option, but it’s going to be heavier than the mirage for same or less power numbers. If I needed an engine/tranny combo i’d look no further than the mirage, going to be the lightest most powerful combo you’ll find for cheap cheap cheap. Keep us posted!

      Make your own, it's easy, I did, just in case mine breaks.

      At the suggestion of one of our members, here's some info on the gas gauge sending unit.
      3 ohms is full, 13 ohms is 3/4, 23 ohms is 1/2, 63 ohm is 1/2, 110 ohms is empty.
      Electrical readings are: F=0.75v-98ma, 3/4=1.91v-82ma, 1/2=2.7v-71ma, 1/4=3.3v-62ma, 0=4.1v-52ma, E=5.0v-39ma
      0 is top of red zone, E is bottom of red zone.

      A few pictures (so far) of the engine work - eventually I will share wiring info and other details (if anyone is interested?)  should anyone else ever need to swap an engine in one of these. The replacement engine is a Harbor freight $750 special 670cc,  (lawn mower/industrial type lump) with a few minor upgrades. Should have it back together soon, bolted in. The cold weather slows me down!

      Has anyone done an engine & tranny swap on an 1100cc sand viper?
    • By Earl Middleton
      I have acquired an older Kawasaki Mule 2010 with KAF 540C engine.  The engine is shot so I have the option to either rebuild or replace.  I am thinking a swap to a three cyl diesel out of a Toro mower.  Anyone tried this?  The only reason I am considering this is because I have the mower which is inoperable.  The engine runs great so just wondering if this swap would be feasible?????

      I just finished rebuilding my 800cc SOHC f8b and boy did I wake this little engine up with port, polish , exhaust, cam and valves! I’ve richened up my stock carb about as far as it will go and still seems to be running on the lean side especially under hard acceleration. I’ve read some posts and going to try my hands at a weber 32/36 two questions:
      1- Is this the best upgrade carb for the engine? 
      2- Will it fit with stock manifold? I ordered the Suzuki Samuri  conversion kit with carb...
