Gen 3 JDM vs ADM...?

[hello_042]

Hey!

I'm new to this forums and was interested in getting a Gen 3 Prelude...I guess I'm just interested...what's the difference between the JDM and the ADM B20As in the Gen 3 Preludes? I've tried looking it up for the last hour and haven't found anything solid on it...

If the ECU was swapped would that improve much for the ADM B20A? Or is there a lot internally that is different compared to the JDM Preludes...?

Well...thanks a lot guys and I hope to hear from someone soon...=)

Yes, they'll help you out.

But just quickly, the JDM engine isn't much different. Its mostly in the ignition/ecu tune for the type of fuel they use. It wouldn't be over 5kw difference between the engines.

^^ its about 10 hp,

basically the b20a(no number after it, means its the JDM engine) gets higer comprssion than the adm
