What kind of gas mileage difference should I expect after doing a H22 engine swap. I was checking out the weight difference between the USDM 94 Prelude vs the 94 Accord and there’s not a whole lot. So should I expect similar results as the Prelude in the Accord? And how much does bolt on parts affect in a positive or negative way. The reason I ask is because of wanting more performance but still needing a daily commuter. More money I save on gas more I can put into fixing it up.

Thanks

 

mpg? 19-25 depending on how you drive. If you are in vtec all the time then closer to 11.

If this is a major concern, don't do the swap.
