my car is 2001 accord lx 2.3L 4dr sedan vtech

• when i am looking for parts for my car many times i will encounter the question which engine i have and i do not know what is the difference LX -- L4 - 2.3L 2254cc type F23A4 - MFI GAS SOHC
• LX -- L4 - 2.3L 2254cc type F23A1 - MFI GAS SOHC

how do i find out exactly which one my car is?

 

either by ur VIN I think its the 8th or 10th digit (one will b a 1 for ur year so it will be the other one) that will give u the engine code which u can put into google (try "honda vin decoder") and follow links. Also it will b stamped on the engine block somewhere along w/ the serial number.

 

i checked out the vin and there is nothing in the vin indicating whether its a F23A1 & F23A4

 

Found ur answer. I just use google (for everything) I put in "f23a1 f23a4" and it gave me anything w/ those 2 engines in it. I found exactly what u were lookin for on Wikipedia (that & google are probably the 2 best sites).
Under Wikipedia is "Honda F Engines"
F23A1 is 150 hp/152 ft-lb
F23A4 has ULEV certification is 148 hp/150 ft-lb, different exhaust manifold, a 32-bit ECU which uses a wideband O2 sensor when compared to the F23A1.
There is more look it up.

 

There is a sticker on the timing belt cover with the engine code on it. Check to see if it is still in tact.

 

thank you for ur great answers guys

 

I could be wrong but I read somewhere that the 4 (is the ULEV engine) and the 1 is the (VTEC engine)

ULEV 148hp
VTEC 150hp

hope that helps

 

Honda-4-Life - they both are VTEC engines just one of those engines is ULEV

 

They're both V-TEC, but the ULEV engine used a more restricted exhaust manifold with a front wideband O2 sensor so it lost 2hp, but if you use the exhaust manifold from the non ULEV you will get back that 2hp

 

does anyone know how much hp to the wheels the f23a1 has?
i know the website says 150hp but im pretty sure thats not the wheels
