K24 swap?
Hey guys, I'm hoping I'm in the right section here.. I'm considering buying an FD this summer, and I'm interested in the possibility of swapping in a variant of the K24 (the engine found in a TSX/Element/Accord these days) but I have no idea where to start, so I figured I'd see if anybody has any advice or just general speculation. The main reasons I'm particularly interested in this motor are the fact that it's got great NA potential, good aftermarket support, good fuel economy, good reliability, it's fairly low-maintenance, and it mates up with a six speed. Anyway let me know if you guys know anything about this swap or have any ideas on where to start. Thanks in advance =)
Good luck swapping in an engine made solely for FRONT WHEEL DRIVE into a REAR WHEEL DRIVE car. Moving to conversions...

Seriously what kind of response did you expect? Go into the Vette forums and ask them if its smart to buy a Z06 this summer and swap a civic engine into it. I assume your considering this because you think the rotary is going to blow up on you 2 days after you get it, honestly if you abuse the living **** out of it or mod without research hell it might, but I have yet to have a rotary related problem with my car. If you want gas mileage,"N/A Potential" 
, and a 6 speed, just a buy an accord, dont put a beater engine into a nice car. If you think 2.4L "V-tech" with some mods can come anywhere near to the 13B TT BONE STOCK, your in for a BIG suprise. I dont mean any offense but, Im guessing you or the friends you hang out with drive a honda, and think its fast....

okay, several things:
1. I expected a somewhat mature response, and I guess that was my first mistake. Or even thinking that someone else was capable of thinking a little differently.
2. It's Vtec, not "Vtech", which is a phone. And clearly you know jack flying **** about about the K-Series and the numbers people are putting up in much more reliable form than any stock 13B.
3. I do have a honda, and friends who drive hondas, and believe it or not, there are more than a few that would smoke a lot of FDs for a lot less change.
4. Learn the difference between your and you're. Might make me take your advice a little more seriously.

No one here has any idea if it will work because no one here would want to spend (waste?) the time to try it.
Be a pioneer, I have the first documented SR20det FB on the road. No one had answers for me, I wanted to do it, not many here like the idea of pistons in a Rx-7, but it's what ***I*** wanted and I'm loving it.
If ***YOU*** want a mad quik Vtec motor in a FD, two words... DO IT... more words, don't expect much help... if any.

I personally think it is a very bad idea....however its your car. If you want to swap the engine in it, go ahead. Nobody here has to drive it...what they say is strickly opinions. I have to disagree with you on rotarys not being reliable. Mine has never left me walking, granted it is stock...but I drive the crap out of it and it has around 200,000 on it. A full out race rotary wont last long (but then again no full race motor lasts that long), but a stock or slightly modded rotory will last just as long as a stock or slightly modded honda engine.

The K24 and the KA24DE are NOT THE SAME, now who's the stupid ricer? One's the engine form a Nissan 240sx, the other's from the Honda/Acura products mentionned in the guy's original post.
I think it's a dumb idea, lots of things will be in the wrong spot, like hose connections, manifold openings, driveshafts. It'd be a large undertaking costing thousands upon thousands for little reward. It'd probably be cheaper to do an S2000 drivetrain swap, at least it's RWD already, and there'd probably even be $$ left to do hp upgrades.
It's almost always cheaper to go with an established swap, like a V8 swap. There's no reason to swap in a FWD engine, there's lots of very good RWD options out there.

k24
you can do the swap, you just have to buy a k series to honda s2000 mounts, then have a great fabricator to make it work, your deff going to need to go with a s2000 transmission for now if you want to go the cheap way out

K24 to Miata is a known factor. Parts are so readily available for that swap that all you need to do it are wrenches and a credit card number, no skill required. The FD is a large Miata so it shouldn't be too difficult.
I've been toying with the idea of a K24 in one of my FBs. Should be a relatively simple way to get 300+hp in an emissions friendly naturally aspirated package that has decent acceleration. Basically like having a built 13B but without making everyone gag at traffic lights.
Also, K24A2s are CHEEEEEEEEAP on eBay. Like $700 cheap. Don't bother with anything but, there's a lot of "you can't get there from here" between a common K24 and the 200+hp version.

i think if you kept the revs down a little, it would improve things a lot. they just do not have a lot of margin for error like a rotary does
