May add 20-30% But I'd have to se the dyno # to believe that.
To set up an engine to run those carbs correctly will require re-cam-ming the engine and extensive exhaust mods.
Not to mention the head porting and valve train work.
If it was that easy we would ALL HAVE GONE THAT ROUTE LONG AGO.
Look, you bought a Samurai. If you wanted a Porsche you should have bought one.
The 1300cc hp can be increased in small increments very easily.
A cam , exhaust and carb upgrade, ( Webber, Toyota, CV, or Holley 5150, All work nicely.
Some work better than others off road.
NONE will double you're HP.
That costs real $$$$$$ Talent and time.
Any one telling you any different is blowing smoke up you're nether region....
The 1300cc Suzuki motor suffers from the same problems ALL Suzuki motors are prone to. Week crank case journals.
If you push it past 100hp plan on stress cracks in the block.
Just realize that no matter what you do to you're rig. IT is, and will always be a utility vehicle. Not an economy car and defiantly not a race car.....
This is how you double the HP in a Samurai.
