I have a 86 prelude si and I have an f23a from a 2000 accord can someone with more knowledge inform me on just how hard this will be and what I can do to help myself..

 

is there even axels that could work?

 

Couldn't I just use an h2b adapter and use the b series transmission and drive shafts?

 

If you have to ask basic questions like this then this is not the swap for you. There is very little gain by going to an F23 engine which is an economy oriented single cam. Just because you have it available doesn't mean it's worth figuring out how to get it to work. If you're really set on doing it then you'll probably be one of the first. Search for H22 swaps for your chassis and it will be...vaguely similar.

 

I'm an very set on this engine it's just a tank and I dont feel like hunting an h23 and yes it is an economical engine but I've seen good power pushed through them and I'm only looking for 300 to 350 horses in a daily "race car" and if I'm correct won't the h22 twin cams fit on the f23 block with some fab work and a good tune?and you are right this may not be the swap for me but it's the swap happening🤷‍♂️😅

 

Thank you aradin... I am definitely over my head and just jumping into this but its till happening and the reason for the f23 is its dirt cheap and makes a great boosted engine. If I'm remembering correctly cant you put h22 cams on the f23 with some fab work and a good tune and even without work done to the engine it's a 60+hp boost without

 

sounds more like Gyro Gearloose stuff

 

You just got me so good TimiK....that's kinda the idea I guess I got time so why not.

 

Any motor that is not the A20 will be a better motor to start.
The F23a is a bigger displacement motor so that in itself is an upgrade in power.
Then if you do decide to go with an H22 head swap, then you are going to be in a lot deeper with the project since you will need to fill a couple of holes on the head, modify the rear waterpipe, modify the waterpump to accept an H22 waterpump sprocket to work and a few more mods.

That is all before you get to making the mounts, I know of one 2nd genner Max who did the full H22 swap which this is essentially going to cost the same plus more to mod the head to work with the block.

Here is Maxx's H22 swap into his 2nd gen: https://www.preludepower.com/threads...a-swap.313118/

So what you want to do is going to be the same plus more work to make the H22 head fit the F23a block.
