Hey Guys,

As some of you already know I'm on the search for a new S2000 engine. I'm coming across a lot of different engine codes and I want to know which is which and which is best for what (that kinda confused me right there, lol)

Anyway, below is what I've gather in terms of the 9K RPM 2.0 liter engines:

F20C - JDM S2000 engine - 250hp higher compression then USDM motor
F20C1 - USDM S2000 engine -240hp
F20 - not sure. I've seen people post F20 but I wasn't sure if it was JDM or not

Now I'm I might want to supercharge my car in the future and was worried about the higher compression of the F20C engine in terms are how the Comptech/Vortech/SOS supercharges were originally designed to work with. Is the higher compression a result of pistons or a simple head gasket with I can replace myself?

I also worry about the valve spring problem which actually destroyed the current engine in the car (something like it fell in a piston). Is the JDM engine less prone to this malfunction and is there any preventive measure I can take to avoid it? (like a new valve train)

Finally my other option is the F22C engine (I think thats the USDM code). I hear its more reliable although it doesn't rev as high, to some isn't as fun, and is more expensive. But if its a better engine overall I might just go with that.

Please give me your thoughts and opinions, thanks.

people are just lazy to type f20c or f20c1,there is no f20.i dont think the higher compression is due to the head gasket,id find the usdm version if you want a ap1 motor.
f22c have lower redline so it does put less stress on the engine so you could say its more reliable.

 

If the add does not specifically say the motor is JDM then I would assume they are all F20C1's.

I am almost 100% sure the pistons are the only difference in the in the JDM motors, as compared to the USDM. Obviously the ECU's and harness' are not the same.

 

F20C1 is what I would go for....I would rather rev higher than have more stroke...with an FI engine you can stuff more boost and the higher you rev it -- the more power you will have.

Upgrade the valve springs/retainers and keep up with the maintenance.

F20C1 laid down 703whp on stock motor with a very nice turbo setup.

With the maintenanc done and a few safety upgrades Im sure you could make all the power you want from a boosted F20C1...

There are 2.4-2.5L stroker motors available if you want monster torque (for a 4cyl Honda)
