F23
Ive been looking into motors now that mine is shot... and im finding F23 motors for the same price as a F22. I know its only a 5hp gain... but for the same price, you cant go wrong. Especially because a newer engine will most likely have less mileage.
Other than the OBD issues, is putting a F23 in my car going to be a big deal? What ECU would I use, I dont think I can use a F23 ECU cause of the immobilizer. Can I use my current ECU?
Everything else should be the same, correct? Both my CV shafts are almost brand new, so I dont wanna have to buy different ones.
The worst part of this whole situation, is my car only has 95,000 miles on it!! :rant:

well wtf did u do to kill ur engine? i'm happy w/ my F23...but then again it came in my car from the factory...
you had an F22 before correct? i don't know what aftermarket parts you had on it but some of them may be transferrable to an F23 (fuel rail, cam gear, some pulleys are all same part #s), looking at how many posts and hearing how you phrased your question it sounds like you already have a knowledge and aren't a noob so i may have just wasted my time w/ what i just said
i haven't heard of too many people swapping an F23 INTO their car...so i'm not 100% sure what you would have to do with the ECU...if nobody gives you a straight answer here i'd suggest calling honda i'm sure they could tell you what would work
OBD2 sucks try to avoid it haha
i think F23's are a good engine to replace with because they're a dime a dozen...they have decent power but are a bitch to mod because there aren't all that many parts out there for them (compared to H22 or something to that nature) and once you go extreme with them (internals and such) most of it has to be custom which is mad expensive...
if you're not looking to go wacko w/ the engine go for it...if you are then might as well spend the extra cash now and get an H22 cuz i think it'll be cheaper in the long run...
i'm sorry if i went in a direction that your question was not intended...if you were just trying to figure out if the f23's 5 extra HP was a good investment for the same price then yeah i think it is so long as you don't have to spend a bunch of money getting it to run since it's not intended for your car

the price of converting to OBDII is something to consider too, I have no clue how much it costs. If you're looking for a replacement engine, my 1995 f22b1 with 120.000 miles is departing from my Accord soon, I'll sell it for cheap-like, 100 bucks plus shipping or something.

Have you thought about rebuilding your old engine with new rings and such, do you know what parts have failed?
A DIY engine rebuild could be as cheap as a few hundred bucks.
The F23 will be a pain to wire in, for 5hp, just find a good low milage version of your exact engine if you are going to swap for another F-series.

The price of converting the f23 to obdI is free, cause all you have to do is cut the harness off the bottom of the block.
Everything bolts up, you have to use the f22 altenator bracket, your ecu will be fine, everything is plug and play, the f22 mani fits to the f23, the f22 header fits the f23. I am finishing mine up here soon, just need to replace my clutch line, and my 5spd and swap will be done.
Everything bolts up, you just have to cut the harness at the bottom of the block off, you will see what I am talking about when you get it.

i'm pretty sure there's more to obd2-obd1 conversion than simply cutting the harness...i haven't attempted it but nowhere have i read that it is that simple...

I just done this swap and its pretty simple, F23a1 obd2 IN 92 prelude obd1, tfor the hard part everything bolts up perfectly tranny mount, engine mount, back and front mounts - and you have to use like 92-93 accord distributor with external coil, and f22 or h23 intake manifold you have to modify the gasket and block a coolant hole and cut off a pice from that manifold you will see if you do it, then just use h23 engine wiring and ecu.
