  1. Naturally Aspirated
    I'm looking to add some performance to my 1990 3rd gen 4WS which has the oceania market B20a6, I know that there are hurricane headers that I can purchase but I'm looking for 4-1 headers rather than 4-2-1. Are there any 4-1 headers for a B20a6? Also what other headers are compatible with the B20a6?
  2. 3rd Gen
    Hi guys! It's been a while and I've managed to get the engine rebuilt for my 3rd gen prelude (engine b20a9). However, even with all the internals of the engine replaced, it still seems to have difficulties starting the first time of the day. After trying 5-10 times, it starts. Also, when...

  6. 3rd Gen
    Alright, so the other day, while driving, my car started running really poorly, so I pulled over to find oil all over the passenger side of my engine bay. It came from the cylinder position sensor, which is connected to the exhaust cam. It seems like oil leaked into the sensor, causing it to...

    Does anyone know if/what valve keepers from other B20/18/16/H22/23 engines are compatible with the B20A5? I have heard a rumor that the H22/23 springs and retainers are compatible, but nothing about the keepers and whether that included the variants of the B series or not. Any help is welcome!
  8. 3rd Gen
    I'm in the middle of a top end rebuild and desperately need of a lower timing cover. I was wondering if anyone has any knowledge of capability with any other B-series engines. My main concern is that the mounting points won't be the same, but if most of the points line up, then I would use it at...

    Hello prelude community it’s me again… unfortunately😂😂 I’ve figured out how to jump the OBD connector to get the CEL to flash the codes. Only problem is I can’t tell which code it is this time. The first long flash is what’s confusing me. Below I’ve linked the video I posted on youtube with...

  13. 3rd Gen
    Picked up a 89 beater with plans to freshen up and swap in a b20a5. Wheel hubs all around are rusty and gross as shit. Looked around on rockauto and all the common retailers for some replacement hubs, to no avail. I assume they're completely discontinued, with no aftermarket options. My question...

    Been working on my 1991 Honda prelude and turns out since the timing was off the valves are bent. Instead of giving up I’m going forward in replacing the valves. My end goal is just to have a good running engine and not going to crazy on my budget. here’s a list of what I plan on buying and...

  19. Introduction
    I have not slept since I saw the Craigslist post. There is a listing for a 3rd gen 4WS in Idaho for $2500 and I’m meeting the owner today! It is kind of high mileage but runs and drives good with a clean title and no body damage. I have no idea what this thing is actually worth, but I love...
  20. 3rd Gen
