So was doing some random surfing today and found that a popular combo engine swap is using the 4cylinder K24 block and transmission from a 7th generation Accord with a K20a head from the RSX type S. Apparently this brings up the torque and HP numbers greatly.... with >200hp combo attainable.

Any gear heads here knowledgeable about this and is this a doable mod in an accord? I could totally see doing this in a few years but just wondering how much ECU and wiring changes might be required..

Apparently the head is a straight bolt-on.

Well, did some quick searching and this appears more difficult than I thought. Apparently the accord pistons don't have the proper valve reliefs, etc... just the tip of the iceburg.

yep, you need a CRV block to make a K24/K20A2 hybrid motor. but i'm sure you can make it work with different pistons that give a bit more clearance.

another heavy engine mod is putting a tsx tranny on the I4

heres one of the threads about that over at gen7, theres a bettter one, but i just couldnt find it http://forums.gen7accord.net/viewtopic.php?t=3591

Yea us K24 owners got jipped with a cheap, pseudo-vtec head. The K20s have real VTEC technology (there's a big difference when it kicks in). I read it in honda tuning magazine.

go over to gen7accord. they have a tsx head swap.
