    A2 Head Swap

    How's it going? I have just bought an Ep3 and i think its awesome, my first honda. I was looking around and i am interested in an A2 Head swap, i wanted some feedback on this swap. Did it wake your Ep3 up? Does it feel like this is the way the SI should have been made? I also want to know what everyone thinks about using Skunk2 parts to rebuild the head, cams, cam gears, springs, valve and retainers. i dont want to do to much to the Ep3 even though im sure that seems like alot. I want to build the a2 head, an intake, exhasut, header and k-pro in terms of engine performance. So any input or feedback is greatly appreciated.

    Dont waste the money on a A2 head swap. Take that A2 head and put it on a K24A1 bottom end.

    The A2 head on the A3 will be mediocre at best.

    Skunk 2 is crap IMO.

    Brain Crower is the way to go for reliable horsepower.

    Skunk 2 sucks dont even waste your time on it.....Brian crower all the way....you wont be sorry messing with brian crower.....and instead of buying a a2 head swap just buy a k24 motor and swap it in your ep3 will definitely pull harder then a a2 swap on your stock a3 motor

    Wake it up with some Boost. The K20a3 response very nicely to it.

    supercharger or turbo kit works very well. you can run 10 psi very nicely.

    Do what I am doing. I dont want to scrap my 40000 miles K20A3.

    So, what I am doing to satisfy myself is getting something new one at a time. Each time I get something new, I feel satisfied.

    Get an intake; next 3 months or less, get a header; next exhaust; then kpro; then a supercharger.

    It's a technique called "rewarding/treating yourself"

    Then don't scrap it! Sell it and recoup some of the cost of the swap or save it for a rainy day...

    i really wanted to get an a2 head and build it, i figured it would make more power but from what i'm reading i guess its not worth it, so i guess for now i'm gonna settle for an intake,header,exhaust and a reflash... thank you to everyone who posted, all very good information and suggestions anymore just keep the coming
