2.2L Engine swap
 

This is going to be a touchy subject....first off, has anyone done this yet? I was told by well respected board member that it is likely possible to drop the 2.2 in a 00-03, using the existing ecu and all. It may not require any additional engine management. There's quite a few new 04 engines to be had, and I've got a few engine jobs on the hook. A local member is thinking of doing the swap, since the price is right, and he'll retain his orignal engine if needed.

Some concerns are.....
-the powerband may fall off at 8k (which is ok)
-is the engine physically capable of 9k? Very reliable sources say yes at this point...

Please add anything you can to this thread, and we'll see if this can fly!

If someone can post up the rod length, we can tell what the rod:stroke ratio is. I don't know about 9k, but 8500 may be doable and more reliable. I'm sure the F22C can spin to 9k, but for how long what is debatable. Tons of ppl have B18B and B20B (franky) motors spinning to 9k, but no one gives reports on those setups after 100k miles or so to see if they really last and those things have terrible rod:stroke ratios, especially the B20B and the stroke is super long leading to increased acceleration at the points of direction change (TDC and BTC).

Why do you want a 2.2L in a 00-03???

Wouldn't it make more financial sense to buy an 04'?

Usually people would want the 2.0L dropped into the 04'... But that also is bad for your wallet :)

The F22C is not designed to handle 9000 RPMs... The piston speed would be much faster then the F20C. It would be like running the F20C to near 10k RPMs...

Electronically, you won't have any issues hooking up the 2.2 to the 2.0's PCM. Both engines use the similar harness/sensors etc. I don't have an ETM here, but honda rarely moves PCM pin location on such similar engines. It's just cheaper to use ehat allready exists.

If you were to use a 2.2L PCM, you would need the VIN from the original vehicle and a Honda dealer to program the Immobilizer keys.

The only way I'd run the 2.0 PCM is after doing the piston speed calcs on the 2.2 at 9200 RPM. If the speeds are too high, maybe a external Rev-limiter woud be a cheap alternative to the 04 PCM.

The fuel maps have to be different. The 2.2 is 10% bigger there is no way that it would be using the same air/fuel ratio as a 2.0. The timing is probably different as well.

I think Sideways among other members already do this..

:iagree:

Also, this is not the first time this question has come up on the forum and other issues also involve valve springs. I asked at my local dealer while my car was in for an oil change and the '04+ models do use a different part number than the older S2000's on the valve springs. I'm assuming you're talking about a complete engine swap here and not just the block.

I don't know what the specs are on the springs in terms of the tension they exert to close the valves but I think it would be worth investigating that before trying to spin the 2.2L engine to 9k. It may not be an issue but if I'm right, you're running a real risk of "eating" pistons and valves in this little experiment.

Good luck & Drive Safe,

Not on stock internals.

Piston speed of the 2.2L at 8k is the same as the piston speed of the 2.0L at 9k.

Unless you're a Honda engineer, don't post what you don't know. Opinions yes...
$5k for an 04 engine installed, or 33k plus fees for an 04...some people can't just buy a new car when the old one lets go...

Then why potentially destroy $5k worth of engine swapping one and revving to 9k when its not supposed to? Seems pretty risky since you don't seem to be that financially secure. Just posting my opinion...
