Whoops, been away for a while, I believe it was this one: https://www.amayama.com/en/part/honda/90181s7a000

Another gift from my brother, photoshoot session. Unfortunately it isn't completed because my MAP sensor gave up mid-session so I spent the time making it running again.

Huh, I missed it. Yes, all F series engines with A suffix should have the same bolt pattern on manifolds.

Not a problem, I actually meant to say that h23a2 manifolds fit on f20a4 and in that case o2 bung is on the donwpipe before the cat, but you didn't mention the exhaust so I didn't want to jump to conclusions.

5th gens are OBD2a. F20a4 5th gen only has one o2 sensor. Except newer models that have true OBD, only OBD2b Hondas like Accord Type R have secondary o2. OBD2a doesn't have a secondary O2 sensor, nor an OBD2 port, but it does use OBD protocol inside the ECU. You can get adapters from Prelude 3pin po...

Not at all, exactly as @Scott560 says.
They go through Global shipping programme so there will be no extra fees on what you pay on Ebay, import duties are calculated in. Mine totaled to 60USD.

I don't believe they exist.

They do, I have them: https://www.ebay.com/itm/222792025729

They are not OEM, but look rather decent:

Well no, f22b has 8.8:1 compression ratio which is very low for naturally aspirated engine. If you want to go low boost turbo then yes, leave stock pistons. If you want to gain any power as NA, you absolutely must use different pistons, be it custom ones or from some other car. You want 85mm bore wi...

Brother got me new licence plates for Christmas. Double (or triple?) win: 1. My initials are BB 2. BB6, obviously. Even though it is actually a BB9 I will let it pass since it's faster than a BB6 :) 3. 3 digit plates are ultra rare in my city, I can't remember when is the last time I saw a non 4-dig...

No need, I am here :) Your block is 85mm bore and 95mm stroke, while K20a pistons are 86.5-87.00 mm. That is a lot of overbore, I wouldn't trust it but if you decide to go with it, I see no other problems in your list. Few things to take note of: You wil have to weld some material to the head to fit...
