can anybody tell me if I have to change my ecu out of a 90 lx copue for the 97 f22b2

 

yes, and you'll need to do an obdI-obdII swap.

 

so it will be just the ecu or the ecu and the harness

 

You're going to need the 97 f22b2 ecu, the f22b2 wiring harness, and obdI-obdII conversion, and I'm not sure whether you'll need new axles.

 

so is it worth it because I found an f22a4 for the same price with the same miles.....

 

really depends, what are your eventual plans with yout car, your vision of your car so to speak.

 

well I want to add a turbo but at a lower ratio the the stock compression, and run somewhere in the low 12s maybe 10s if the block can withstand a 45psi boost

 

45 pounds of boost??? That just sounds like a lot of money.

 

Well, the 1997 f22b2, with it's OBDII, is gonna be one mroe extra thing you're gonna hafta convert to, and OBDII is a pain in the butt to tune with compared to OBDI, so stick with an OBDI engine, I'm pretty sure all f-series accord engines are in the 8.7:1 ratio or around there so it's good for boost. So, I guess you should look for an OBDI f-series engine with good compression in all four pistons, and low miles. . .

 

thanks for the help found one with 55,000 on it
