4) The block is quite a bit larger than exsisting K-series (clearance issues)
5) All belt driven accessories mounted towards front of the block. Every Si owner knows how short our engine compartments are.
6) Does not bolt up to exsisting K-series transmissions. Uses a version of the RL tranny which is quite large and heavy. (Honda claims the stock K-series trannies are not strong enough to hold all the torque) (May not be totally true since there are plenty of turboed RSX's with over 260 lbs tq)
7) Connecting rod bolts are M8 where as other K-series use M9 (only a problem if you want more power)
8) Stock turbo is limited to 13.5 psi (must upgrade turbo if you want more power)
9) Top mount intercooler makes the engine very tall
10) Good luck getting the ECU to interface with our car</TD></TR></TABLE>

It can work just a little ingenuainility and a fat wallet if i had time and a motor like that yeah i would attempt it mostly for the hell of it and yeah it would suck if it was in but the motor couldn't run cause of the ecu but i'd ghetto rig it in a way to make it work..

An RDX swap is just too unlikely considering all the statements that BlueIntegraBoy listed above. Even if it was somehow or someway possible, imagine the amount of labor, money, precise examination and customizing that would need to be done to do a swap that only puts out a factory tuned 240hp/260tq. and if you were planning on building the motor, then whats the whole point? just get yourself a regular K and call it a day.

It would make more sense to just built and boost a K instead of dumping money just to MAKE the K23 engine fit.

you're preaching to the converted. A lot of people think the H2B in an 88-91 civic is impractical but I did it anyways.
Did you even read any of the points that were mentioned earlier? The engine isn't even THAT great, it's just the fact that it's a factory boosted K. It just doesn't seem worth it. Maybe just to say I have an RDX engine. It reminds me of the F2K.

well im sure if someone could put a LS1 in a ek like the civette or like how that other guy made his own mounts and other parts to put that boosted rotor engine it must be possible to do this swap, but like everyones sayin u should just got boosted k lol

My thoughts exactly. For the hassle and expense of swapping in the RDX engine with an inferior tiny turbo, why not just swap a stock K20 and boost it. There's a lot more potential in the latter option without all the previously mentioned obstacles of the RDX swap.
