OK, here we go. The F23A1 is the standard 4 cylinder that came on 6G ( 6th generation ) Accords, like my 2000 Accord. The engine comes to 150hp and has pretty good torque as well.
Heres the thing tho. You can get a f23a1 for pretty cheap engine, tranny, ecu, everything!!!!
But if you're gonna swap try the h22a1 or f20b.
Heres why:
The h22a1 is more expensive as is the f20b but they are actually smaller in displacement than the f23a1 and have way more hp. So.....
IN CONCLUSION
Swap = Good f23a1 = bad choice.
Shit I'll sell you my f23a1 tranny, ecu, wiring harness, A/C, whatever you need for $1000 plus shipping but you are better off without it.
