Which would be quieter, more fuel efficient and more powerful?
The Toro TXP engine is almost a clone of the Honda GXV engine. Real bearings, cast iron liner. The Honda engine is very light duty, lots of plastic parts, plastic camshaft, plastic cam gear, belt driven camshaft, no cast iron liner. Basically, the Toro TXP engine is the better engine. If you are going to keep the engine long term (20 plus years) it will probably be easier to find parts for the Honda. Once Toro stops importing that engine, parts supply will likely dry up. UNLESS the TXP is a very close copy of the Honda GXV, in which case parts will be cheap and available forever.
Realistically, they both will run a really long time if maintained. Both are good engines. I'd honestly buy the cheaper one. If the TXP engine is cheaper, I'd go that route. Plus to boot, on paper the TXP is a better engine.
Bubba is spot on, however, like he mentioned, I'm not sure how close of a copy the TXP engine is. I realize you already bought your mower, but i went with the SR4 w/ the Honda GCV 160 back in 2012, its been a great mower. I would hate to think that something stupid like a bent pushrod would cause you to replace your whole TPX engine, but its possible if parts sourcing is not there. Toro does not provide consumers any part #'s for TXP engine components other than normal service parts [air filters, spark plugs, etc]. I would have to think that they would probably just unbolt the motor and replace it with another $100 TXP motor vs replacing the broken push rod as an example. Sad times we live in.
