Going Secret AP1s calcs, 8500rpm should be fine and at the approximately crank journal speeds as the 2.0L. The F22C does run a different rod length (I don't remember what the length was, but it is different), so there's going to be a greater variation in the actual piston speeds than the crank speeds. I don't see why 9k has to be the magic number...yeah, it's great for bragging that we can go to 9k, but I'd rather have a better power/tq curve. If the power drops off with cams at 8500rpm or so, I say leave the redline about there. Let us know how it all goes, but I think somewhere around 8500rpm would be a better bet.

 

Can't wait to see how this turns out! Good luck guys.

 

Ok so I've kept my mouth shut up till now, but I do know one board member that's been running(and tracking) a MY00-03 ECU on a 2.2L for probably 9months now. I'll PM him and see if he wants to PM about his experieces. He has dyno charts for this setup already. Might be useful. So far so good with his car.

 

The plan is for 9k so that you dont need to add anything new. Using the factory supplied ECU and no external rev limiter. Replacing the ECU with the 04 would require immobilizer re-programming. The goal of this project is to make as cheap of a swap as possible. A MSD rev limiter is cheap and easy to install, but if it's all fine at 9k why really bother to put it in? I think that's what we're trying to determine here. If at 9k everything will be fine. The powerband falling off was stated to not be an issue.

 

 

I don't think max piston speed is the real issue here. Remember, the piston feels the same forces that you or I do. So, acceleration and not max speed is what matters.

Given that the 04 has a longer stroke than the 00-03 engines, for each stroke, it has more distance to accelerate and decelerate than the engine with the smaller stroke. So, you should be able to run a higher piston speed than in the F20C without consequences, provided the materials (ie conrods, pistons, crank) can handle the added stress.

In short, for this case, do a few calcs, and then try it out in the real world on a real car.

 

Sounds cool! I'm curious to see what a stock 2.2L motor can put down from 8200-9000rpms.

If it all works, it would be interesting to see if someone could get a JDM/EU '04-05 ECU (which should have compatibility with the new keys/immobilizer I'd think), a JDM/EU '04-05 gauge set and run the 2.2L @ 9000rpms. My friend is moving to Tokyo, maybe he can buy the parts and mail them to me

Or at least see if we can get the MY04-05 running to the tune of 8500+ rpms to make some extra power with a full engine management system or maybe some sortof piggyback (?!).

Keep us up to date billman250!

 

billman250 for trying something new and interesting. Hope everything works out.

 

I am subscribing. Let us know how it goes.

 

damn! hope everything goes well... I'd like to know the results
